4 INTRODUCTION As a trusted data center infrastructure partner, Brocade is helping organizations worldwide transform their data centers to reach the next level of performance, scalability, end-to-end connectivity, and ease of use. Our products and services help organizations scale their infrastructure to manage and protect their digital data assets, improve performance of the applications that create business value, and ensure that users and applications are always connected to their data. From this vantage point in the data center environment, it is our mission and responsibility to build and support a data center fabric connecting users and applications to their data. The Brocade data center architecture provides a blueprint for building a cost-effective data center with products, services, and partner alliances to reduce the complexity of connecting, accessing, protecting, migrating, and storing data for applications and users. A key component of the Brocade data center is Brocade Data Center Fabric Manager (DCFM ), a unified fabric management software platform. Brocade DCFM builds upon the recognized capabilities of Brocade s existing fabric management software, Brocade Enterprise Fabric Connectivity Manager (EFCM) and Brocade Fabric Manager. DCFM leverages a proven fabric management architecture and delivers innovative new features, it provides the following key capabilities: Compelling increases in scalability and performance, which are essential to support present and future infrastructure management needs Integrated, unified data center fabric management to extend the scope of management from individual switches and directors to pools of physical servers and storage that leverage data center virtualization technologies Simplified management of physical and virtual data center infrastructure, to expose policy-based fabric services such as Adaptive Networking and data-at-rest encryption services Open standards interfaces to simplify integration with Brocade server, storage, and infrastructure management partner frameworks Reduced management complexity with fewer configuration steps Understanding of Virtual Fabrics and Logical Switches, concepts introduced in Brocade Fabric OS (FOS) 6.2 Integrated management for both Brocade FOS and M-Enterprise Operating System (M-EOS) users Unified management of Storage Area Networks (SANs), Host Bus Adapters (HBAs), and Converged Network Adapters (CNAs) Server virtualization support Support for Fibre Channel over Ethernet (FCoE)/Converged Enhanced Ethernet (CEE) Brocade DCFM is easy to deploy and use. For example, DCFM Enterprise requires only one part number and a Brocade Enhanced Group Management (EGM) FOS license is bundled with Fabric OS (for most customers. contact your Brocade representative or your storage vendor for details.). Note that Fabric Manager is currently at End of Life (EOL) and EFCM is in sustaining mode, which means that Brocade supports ECFM only as necessary. This paper explores several of these key capabilities to help data center managers and administrators better understand the advantages of deploying Brocade DCFM.

It helps automate operations across multiple switches to save time and streamline repetitive operations, which are typically prone to error. Brocade EGM drives consistency across fabrics, while minimizing the risk associated with potential downtime due to configuration mismatches. EGM provides streamlined troubleshooting for more effective fabric monitoring and diagnosis. Brocade Data Center Fabric Manager (DCFM) 7 of 50

8 NOTE: In this document, features and capabilities are described for DCFM Enterprise; these features may or may not be present in DCFM Professional Plus or DCFM Professional. Upgrade Paths Figures 2 and 3 illustrate the current EFCM/FM-to-DCFM Enterprise upgrade paths and DCFM Professional/Professional Plus-to-DCFM Enterprise upgrade paths. Note that there is no upgrade path from EFCM or FM to DCFM Professional or Professional Plus. Figure 2. Supported EFCM/FM to DCFM Enterprise upgrade paths Figure 3. Supported DCFM upgrade paths RELIABLE AND INNOVATIVE ARCHITECTURE The Brocade DCFM architecture is built on a reliable and proven code base and adds new and innovative capabilities. The following list describes some of the key features of its architecture: Built on an industry-standard Java EE Application Server foundation Architected for scalability and performance Leverages a multi-tier architecture: Embedded Relational Database Management System (RDBMS) for data persistence Brocade Data Center Fabric Manager (DCFM) 8 of 50

9 Web-started Java client enables easy deployment of client infrastructure and allows for automated client updates when the server is upgraded Modularized independent mid-tier services for data collection from managed elements Leverages event-driven status updates to reduce unnecessary polling of the fabric and switch elements Collects, persists, and ages over time (user-configurable) the performance data Leverages a built-in Rules Engine to enable policy-based unified management Provides a powerful Reporting Engine to generate comprehensive out-of-box canned reports Provides out-of-box ODBC/JDBC drivers for access to the DCFM database for custom reporting and analysis (for example, Crystal Reports, MS Excel) Enables user-defined client views to visualize only segments of fabrics that are of interest, which allows for faster drill-down to analyze potential problems Supports virtualization for both DCFM server and DCFM client Enhanced Scalability and Performance In addition to performance, scalability is required to keep pace with data storage growth and the corresponding increases in fabric data movement. As detailed in the Brocade DCFM Release Notes, the supported limits for DCFM depend on the host configuration. Table 1 provides the supported limits for Brocade DCFM. Table 1.

IT organizations can analyze performance trends over time to maximize asset utilization and aid in proactive capacity planning. DCFM provides practical features that enable holistic visibility across a global infrastructure to avoid unintended manual errors the type of error that could be catastrophic to businesses. For example, zoning information could be overwritten by two or more users on the same zone set. A wizard-driven approach streamlines configuration activities (setting up cascaded FICON fabrics or FCIP tunnels) and troubleshooting/diagnostic activities (determining why two devices cannot communicate with each other or why sharing of devices between routed fabrics is not working). These commonly performed tasks can now be preformed across groups of switches in a single operation: Firmware download Fabric configuration setup Backup and restore of critical configuration and performance data Collection of diagnostic data for troubleshooting Automation of repetitive tasks enables IT organizations to ensure configuration consistency on a global basis across their multiple fabrics and across geographically dispersed data centers. For a more comprehensive explanation of DCFM features and how to use them, see the Brocade DCFM User s Guide for your version of software. Performance Monitoring and Management Brocade DCFM enables IT organizations to monitor fabrics on a real-time and on a historical basis. DCFM uses a policy-driven approach to set thresholds for both individual ports and end to end between source (application) and target (disk). This allows users to address performance issues proactively, rapidly diagnose the underlying causes, and quickly resolve them before the SAN becomes the bottleneck for critical applications. Furthermore, IT organizations can use analytical and reporting features to study performance trends over time and make changes to maximize asset utilization and plan for future capacity needs. Some performance monitoring and management capabilities are listed below: Real-time performance data collection, monitoring, and graphical display (across FC, FCIP, and Gigabit Ethernet (GbE) ports and connections), shown in Figure 3; includes support for both performance data (Tx/Rx) and error counters (CRC/sync loss errors, signal losses, and link failures) Historical performance data collection, monitoring, and graphical displays (across FC, FCIP, and FCR ports and connections); includes support for both performance data (Tx/Rx) and error counters End-to-end monitors (both real time and historical) from source (application) to target (disk) Top Talker monitors determine the data flows that are the major users of bandwidth bandwidth usage is measured in real rime relative to the port on which the monitor is installed.

11 Policy-based, user-defined performance thresholds Color-coded marching ants on the topology to show traffic status Out-of-box reports (Top N ISLs, Top N Device Ports) The performance of the following objects can be monitored: Switches and FC, GbE, Inter-Switch Link (ISL), and device ports; customize the device tree to show only ISL ports or only device ports Active FCIP tunnels Trunks End-to end-monitors Managed HBA ports Real-Time Performance Monitoring The current release of DCFM supports multiple open instances of real-time performance monitoring (previous releases supported multiple open instances only for Historical graphs). Figure 3. Real-time performance graphs Historical Performance Monitoring Historical data collection can be easily enabled for the entire SAN or a selected set of fabrics. Historical performance graphs display the Top N performers for a selected object type. The historical performance of the following objects can be monitored: FC, ISL, and device ports FCIP tunnels FCIP statistics, including timeout retransmits, duplicate ack. retransmits, window-size RTT, and TCP out-of-order segments End-to-end monitors Brocade Data Center Fabric Manager (DCFM) 11 of 50

12 The following are details of the historical performance capability: Data is persisted at each polling cycle of 5 min. Each port has a maximum of 606 records. Note that starting in DCFM , these limits are not user configurable. A Round Robin Database (RRD) style aging scheme is used. Reporting can be configured for these intervals of time: 5 min, 30 min, 2 h, or 1 day. Interpolation is supported for up to 6 data points, which is helpful when there are missing data points that might skew the trend line. Historical tabular reports can also be generated. NOTE: 600 KB of raw storage is required for each port; approximately 7 GB of disk space is required for 9,000 ports. Top Talkers The Top Talkers window, shown in Figure 4, displays a real-time (top) and historical (bottom) lists of top conversations for a selected switch (Fabric Mode) or F port (F Port Mode). (Multiple open instances of the Top Talker dialog is supported.) Figure 4. Top Talkers window Brocade Data Center Fabric Manager (DCFM) 12 of 50

13 End-to-End Monitor Support End-to-End (EE) monitors are user configurable. For example, in the dialog box shown in Figure 5, a user selects a fabric from the dropdown menu at the top left, selects an initiator port from the list, selects a target from the list, and adds a new EE monitor to the table on the right. Fabric OS (FOS) supports a maximum of 4,000 EE monitors. Figure 5. End-to-End Monitors dialog box NOTE: EE monitors must be provisioned to view statistics for both real-time and historical performance. Brocade Data Center Fabric Manager (DCFM) 13 of 50

14 User-Defined Performance Thresholds Threshold policies can be created and applied (shown in the dialog boxes in Figure 6) to entire fabrics and/or individual switches. Figure 6. Create Threshold Policy and Set Threshold Policies dialog boxes Brocade Data Center Fabric Manager (DCFM) 14 of 50

15 Marching Ants Marching ants are colored animated dashed lines in the View Utilization view, which display utilization for FC and FCIP, as shown in Figure 7. The range displayed is user configurable, and if no data parties available, a gray line is used. For example, if the data is between 0 and T1, where T1 is the first threshold, a blue dashed line is displayed. Figure 7. View Utilization on the Toolbar menu Zoning Policies can be configured to control the number of Zone database changes. You can: Set limits on the number of editing operations (add/remove/modify) that can be performed in zones, zone configurations, aliases, or zone members before activation Set policies on a per-fabric basis, for example, different policies for disk versus tape storage. Warm users when a policy is exceeded and prevent further changes Additional Zoning features are described in the following sections. Zoning Impact Analysis Brocade DCFM supports the concept of an offline Zone database, so that users can make zoning changes offline without affecting the production fabric. This feature helps SAN administrators, who receive storage provisioning requests throughout the day and want to make the configuration changes required. Typically there is a very small change window each day during which the changes can actually be pushed to the production fabric. The offline zoning feature provides precisely this ability. DCFM can compare the selected offline database with the online database to see which source devices have gained or lost access to which target devices. DCFM provides both host-to-storage (shown in Figure 8) and storage-to-host connectivity views. Brocade Data Center Fabric Manager (DCFM) 15 of 50

16 Figure 8. Zoning Impact Analysis: Host-to-storage connectivity view Additionally, whenever a new zoning configuration is activated, a comprehensive change impact analysis window is displayed detailing all of the changes that will occur in the fabric when the configuration is activated. You can review those changes and make sure they are in line with your expectations. You can also chose to compare the applied configuration with the current fabric configuration as described above. Figure 9. Activate Zone Configuration dialog box Brocade Data Center Fabric Manager (DCFM) 16 of 50

17 Multi-User Zoning Brocade DCFM detects when more than one user is working on the same zone set and provides a notification to these users, shown in Figure 10. Users can then choose to either configure these changes serially or to continue to work in parallel. DCFM provides a compare-merge capability when the users are ready to commit the changes. Users can compare their own changes to the changes of other users to ensure that zone configurations are not accidentally overwritten. In data center environments in which zoning changes to production fabrics are constantly being made, this is an efficient collaboration tool. Figure 10. Multi-user zoning: Compare-and-merge capability Brocade Data Center Fabric Manager (DCFM) 17 of 50

18 Quality of Service Zoning Quality of Service (QoS) is a feature in Brocade Adaptive Networking advanced fabric services, which enables users to set the desired QoS for applications running on both physical and virtual servers through the use of N_Port ID Virtualization NPIV. A High QoS setting gives critical applications the required bandwidth priority, maximum availability, and optimal performance in the event of network congestion. Brocade fabrics can automatically and continuously adapt to changing network dynamics to ensure that critical applications always receive high priority. QoS zones are similar to regular zones with an additional naming convention to designate High, medium, or Low QoS level. DCFM enables configuration of QoS priorities using zoning a paradigm that is very familiar to SAN administrators. Setting a QoS priority for an application, whether it is running on a physical or virtual server, is a simple choice from a right-click menu, shown in Figure 10. Figure 10. Setting QoS priority for applications running on physical or virtual servers Brocade Data Center Fabric Manager (DCFM) 18 of 50

19 LSAN Zoning Brocade DCFM has several features for performing Logical SAN (LSAN) zoning that allows multiple fabrics, whether local or remote, to connect with each other without merging. Only devices that have been specifically zoned within these fabrics can communicate with each other, rather than complete unrestricted access. DCFM consolidates LSAN zoning into the regular Zoning dialog box, but provides a different zoning scope based on the backbone fabrics that have been discovered. It displays potential zoning members based on the backbone fabric and its connected edge fabrics. DCFM allows LSAN zones to be created, edited, and activated in the fabric zoning scope for both backbone and edge fabrics. The DCFM topology supports comprehensive MetaSAN features, which include visualization of backbone and edge fabrics and display of Inter-Fabric Links (IFLs) in the topology. Figure 11. Backbone and edge fabrics showing IFLs Brocade Data Center Fabric Manager (DCFM) 19 of 50

20 Figure 11. LSAN zoning configuration Traffic Isolation Zoning Active Traffic Isolation (TI) zone information is collected by DCFM and persisted in the Zone database. Differences between defined and active TI zones are reflected in the Zone database. Configuration Management Configuration management features provide several benefits, for example, if a switch that had been performing successfully until just a few minutes ago is suspected to be misbehaving due to an accidental configuration, it can quickly be restored to the last known good configuration. Similarly, a user can remove a switch whose lease has expired and replace it with a new switch of the same model without having to manually reconfigure the new switch; it can be provisioned through DCFM. An enterprise may have global corporate standards for switch configuration and requirements. With DCFM, ensuring configuration consistency is easy: replications can be configured from a golden master switch to all other switches. Save Switch Configurations Brocade DCFM allows the user to choose one or more switches from the discovered fabrics and back up configurations to a repository, either manually on demand or automatically on a scheduled basis. Finegrained options include: To back up either specific switches or all discovered fabrics To determine how often automatic backups should occur and how long the backups are retained before older copies are purged, as shown in Figure 12 Brocade Data Center Fabric Manager (DCFM) 20 of 50

21 Figure 12. Scheduled Backup of Switch Configuration dialog box Restore Switch Configuration Brocade DCFM allows configurations that have been backed up to the configuration repository, shown in Figure 13, to be viewed with a configuration viewer. Single-click operations allow configurations to be: Restored to the switch Replicated to other switches Exported from the repository to disk Imported from disk into the repository Figure 13. Switch Configuration Repository dialog box Brocade Data Center Fabric Manager (DCFM) 21 of 50

22 Replicate Master Configuration to Multiple Other Switches The Replicate Switch Configuration wizard, shown in Figure 14, allows the user to select a golden master configuration and to replicate it to multiple other selected switches. Options are provided to selectively replicate any or all of the following: SNMP settings Brocade Fabric Watch settings Trace destinations The entire configuration Figure 14. Replicate Switch Configuration wizard Brocade Data Center Fabric Manager (DCFM) 22 of 50

23 The Replicate Switch Security Policy Configuration wizard, shown in Figure 15, allows users to replicate security policies such as: AD/LDAP Authentication Servers RADUIS Authentication Servers Switch Connection Control (SCC) Policies Device Connection Control (DCC) Policies IP Policies Figure 15. Replicate Switch Security Policy Configuration wizard Brocade Data Center Fabric Manager (DCFM) 23 of 50

24 Fault Management Brocade DCFM allows administrators to manage failures in the data center via the capabilities described in this section. Rule and Actions Support for rules and actions are similar to Brocade EFCM Event Management. The Event Policies dialog box is shown in Figure 16. Figure 16. Event Policies dialog box for configuring rules-based events There are four types of event triggers: ISL offline Security violation Performance threshold crossing User-defined events These events can trigger any one or all of four types of user actions: Launch a script Broadcast a message Send Capture support data (FOS only) Brocade Data Center Fabric Manager (DCFM) 24 of 50

25 Each policy (up to a total of 10) is composed of a trigger and one or more actions; simply put, when the trigger is fired, the actions are performed. Events persist in the database until they are purged based on user-configurable guidelines. For example, event storage allows users to set the maximum number of events to be stored in the database, and once the limit is reached, older events are purged. SNMP Registration and Trap Forwarding Users can automatically register the DCFM server as an SNMP Trap recipient on all switches that it manages, forward traps to other recipients, and register other trap recipients directly on the switches. A simple SNMB trap receiver can be connected to switches in the Brocade fabric, as shown in Figure 17. SNMP trap receiver Hosts Switch Brocade DCX Backbone Storage Figure 17. SNMP trap receiver connected to switches in the Brocade fabric In the SNMP Registration and Trap Forwarding dialog box: Users can select a different listening port number (the default port number is 162). Users can register or unregister other trap recipients on B-Series switches on a per-fabric basis. Additionally, DCFM 10.3, in conjunction with FOS 6.3, supports SNMP Informs for SNMP v3. The Informs tab in the SNMP Setup dialog box, shown in Figure 18, allows you to enable Informs instead of Traps for supported switches on a per--fabric basis. Figure 18. SNMP Setup dialog box Brocade Data Center Fabric Manager (DCFM) 25 of 50

26 Syslog Registration and Forwarding Users can automatically register the DCFM server as a Syslog event recipient on all switches that it manages, forward Syslog to other recipients, and register other Syslog recipients directly on the switches. The Syslog can be accessed from the main menu as follows: Monitor > Logs > Syslog. Figure 19. Syslog Registration and Forwarding dialog box Master Log Event Display Brocade DCFM can display the number of events defined by the user and use pagination when necessary to avoid performance issues. Right-click menus for display options are show in Figure 20. Figure 20. View All event display window Brocade Data Center Fabric Manager (DCFM) 26 of 50

27 Advanced Event Filtering Users can define event filters with greater granularity, for example, see only events that are highly relevant. Port Fencing A feature already present in ECFM is now supported in FOS and DCFM. Port fencing, allows you to configure policies that, when met, stop I/O into and out of a port. Port fencing includes sever categories of port malfunction supported in both FOS and M-EOS: Protocol error, shown in Figure 21 Link The following port malfunctions are supported in FOS only: Link reset Invalid CRCs Invalid words Sync loss The following port malfunction is supported on M-EOS only: Security Figure 21. Add Protocol Error Threshold dialog box Port fencing is supported on: All M-Series switches running M-EOS 9.x All B-Series switches running FOS 6.2.x Switches with a Fabric Watch license enabled Brocade Data Center Fabric Manager (DCFM) 27 of 50

28 Virtual Fabrics DCFM understands the new FOS concept of Virtual Fabric (VF) and Logical Switch (LS). Using DCFM you can enable VFs on switches, create LSs and use them in fabrics. (See the Brocade Fabric OS Administrator s Guide for details about Virtual Fabrics and Logical Switches.) In the Virtual Fabrics Connectivity Map, shown in Figure 22, Logical Switches are displayed with V-tagged icons. Logical ISLs are displayed as logical (blue) Figure 22. Virtual Fabrics Connectivity Map The Logical Switches dialog box, shown in Figure 23, provides an intuitive interface for creating new LSs and assigning available ports. Figure 23. Logical Switches dialog box Brocade Data Center Fabric Manager (DCFM) 28 of 50

29 Port Groups A feature called port groups has been developed in response to customer requests. Port groups allow you to configure, name, and save a logical group of ports as a way to administer them, as shown in Figure 24. A port group can include one or more ports on more than one switch in a single fabric. Figure 24. Port Groups dialog box Port groups have been extended to the FICON environment. Used with multiple Prohibit Dynamic Connectivity Masks (PDCM, a method to define port connectivity), port groups are equivalent to zoning for enabling and disabling traffic on a per-port group basis, as shown in Figure 25. Figure 25. Configure Allow/Prohibit Matrix window Brocade Data Center Fabric Manager (DCFM) 29 of 50

30 The following PDCM enhancements apply in a FICON environment and are introduced in DCFM 10.3: User warning when E-E and E-F port connections are prohibited The ability to provision the same PDCM updates to multiple switches Direct entry of row and column in the PDCM Matrix in the Allow/Prohibit Matrix for enhanced usability TROUBLESHOOTING AND DIAGNOSTICS Brocade DCFM provides powerful wizards to perform troubleshooting and diagnostic activities, and to aid in rapid problem resolution. This in turn helps IT organizations minimize their Time to Resolution (TTR) and maintain SLAs. Device Connectivity Troubleshooting Wizard This wizard checks for a number of conditions (shown below), which if present might prevent devices from communicating with each other. Once complete, it displays the results of these checks and the recommended next steps (shown in Figure 26). Device port status (online/offline) Switch port health status Zone configuration Active ACL DCC policy check LSAN zone configuration Device moved to a new fabric Fabric segmentation FC Router physical connection status Brocade Data Center Fabric Manager (DCFM) 30 of 50

32 Device-Sharing Diagnosis Wizard This wizard verifies whether two selected fabrics are configured properly to share devices. Execution of the wizard results in a report that outlines whether or not it is possible to share devices between the selected fabrics. Figure 27. Fabric Sharing Diagnosis Result window Trace Route Wizard Brocade DCFM provides a wizard a) to perform a trace route check from a source port on a local switch to a destination port on another switch and b) to determine detailed routing information between them. The routing information describes the full path that a data stream takes to go from the source path to the destination path, including all the intermediate switches it traverses. Both the forward and reverse path information is made available. In the current version of DCFM, trace route can also show the traffic path through routed environments. The wizard provides an FC ping option, which performs a zoning check between the selected device port WWNs. It also provides the maximum, minimum, and average Round Trip Time (RTT) for the frames between the device port WWNs and the domain controller. Users can determine the path and latency between given ISL ports and device WWNs, information that is helpful for diagnostic and troubleshooting purposes Brocade Data Center Fabric Manager (DCFM) 32 of 50

34 Advanced Call Home Advanced Call Home allows users to configure Brocade DCFM to automatically call into their OEM Service Center when specified triggering conditions have been met. It enables the service center to be configured on a per-switch basis. This is important, since SAN infrastructure devices are usually procured from more than one vendor and the service contracts for those switches are tied to the respective vendor service centers. Depending on the Call Home center supported by a vendor, the appropriate underlying mechanism is used ( , modem, LAN, and so on). Customers have access to fine-grained control over: Which events trigger a Call Home What DCFM should do in response to those Call Home events, including automatically capturing diagnostic information from the switches as part of the Call Home event Table 3 provides supported platforms for Call Home support.

37 EASE OF USE Brocade DCFM offers a rich set of capabilities, which might be considered overwhelming for end users. But the Brocade User Interface (UI) team managed to deliver a consistent and intuitive user experience, the characteristics of which are described in this section. Common GUI Widgets Library Brocade DCFM uses a common GUI widgets library, a collection of components listed and illustrated below. Consistent behavior across the suite of applications Data-aware functionality out of the box Component operations available through right-click menus: Tables and tree tables: multi-column sorting, incremental search, auto-resize columns, copy cell content, export/copy content, choose columns, editable cell indicators, and overlay tooltip for partially visible cells: Tree: Copy node text, incremental search, expand/collapse, and overlay tooltip for partially visible nodes panels: Clear and intuitive dialog boxes: Status and progress windows and input validation Brocade Data Center Fabric Manager (DCFM) 37 of 50

38 Wizards From the outset, wizards assist you in performing both one-time and repetitive tasks. Brocade DCFM has an installation and configuration wizard, and wizards are presented when a multi-step task is required. Wizards break down larger tasks into manageable steps, and this presentation ensures successful task completion. Steps are listed on the left side of the dialog box, with the task in process highlighted, so that users always know where they are in the process. Onscreen instructions move the process along. The DCFM Main Window The Brocade DCFM main window is a portal to application functionality. Shown in Figure 24, it displays a product list on the left, a connectivity map in the center, and a master log, legend, and minimap at the bottom. Status icons are overlaid on product icons; the worst-case status is rolled up to closed objects on the product list to ensure that they are flagged. NOTE: Access to main menus in the DCFM main window is dictated by Role-Based Access Control (RBAC) privileges. Figure 24. Brocade DCFM main window Brocade Data Center Fabric Manager (DCFM) 38 of 50

39 Connectivity Map The look and feel of the connectivity map is user configurable and scrollable, and it: Displays physical and some logical connectivity of SAN products Includes fabrics, switches, hosts, and storage groups Displays connection and product flyovers with additional user-configurable information Streamlines icon display: one for switches and one for directors/backbone platforms The tool bar (to the right of the map) contains global map zooming and group collapsing functions. Master Log The master log is a one-stop shop for all events. The log can be filtered to display events by category, severity, or user-entered event content. The following are user configurable: Determine log size and enable or disable log paging Hide or show selected events Display event details A right-click menu in the master log is shown in Figure 25. Figure 25. Master Log in DCFM Main window (top) and the View All window (bottom) Performance Legend Users can specify the ranges used in the Connectivity Map marching ants display. Figure 26.

42 BROCADE DATA CENTER AND DCFM The Brocade DCX Backbone family, which includes the Brocade DCX and DCX-4S, expanded fabric size and performance and added new "plug-in" fabric services, such as Adaptive Networking and data-at-rest encryption. In much the same way, SAN management evolved from the switch and director management architecture of earlier products to the policy-based, fabric service management architecture of DCFM. The Brocade data center, shown in Figure 30, defines an integrated, end-to-end data center fabric with seamless infrastructure management. Management extends from traditional SAN elements (backbone platforms, directors, switches and embedded switches) to include the server network and extended branch offices and disaster recovery sites. DCFM scales to handle the management of the physical and virtual data paths between servers and storage and integrates simply with existing management frameworks from our storage, server, and data center infrastructure management partners. Virtual and standalone servers SAN Mainframe Continuous remote replication Disaster Recovery Site B-Series SAN Third-party SAN M-Series SAN Brocade DCX Backbone Brocade 8000 IP Network Extended Data Center Fabric Storage Brocade Data Center SAN Server Network HPC Branch Office Virtual and standalone servers Figure 30. The Brocade data center extends from virtual and physical servers to storage and outward to DR sites and branch offices and IP networks FCIP Management Support for Extension Platforms The release of DCFM 10.3 includes features to support new extension platforms: Brocade 7800 Extension Switch Brocade FX8-24 Extension Blade These include: Comprehensive FCIP Tunnels configuration window shown in Figure 31 (replaces the FCIP Tunnel wizard and also supports legacy extension platforms. the Brocade 7500 Extension Switch and FR4-18i Extension Blade) Enhancements for connection properties, switch properties, flyovers and the topology view Ability to view all tunnels discovered by DCFM across all fabrics Brocade Data Center Fabric Manager (DCFM) 42 of 50

44 DCFM in a Virtualized Data Center Environment As more and more components of the data center are virtualized (from storage all the way to the server), the ability to manage virtual resources is increasingly necessary. Through the use of NPIV in the server virtualization hypervisor, DCFM can identify virtual machines running in the fabric. These are represented with a V-tagged icon similar to the one used to designate Logical Switches: Once these devices are visible in the fabric, DCFM can assign policies such as QoS or fabric services such as encryption to them just as if they were physical servers. In addition, and in order to improve visibility of the virtual server infrastructure for the storage administrators, the following features are introduced in DCFM 10.3: Discovery of VMware virtual machines via VMware ESX Server APIs, as shown in Figure 32. Figure 33. Add Host Discovery dialog box Brocade Data Center Fabric Manager (DCFM) 44 of 50

45 Identify which physical servers are running VMs (Figure 34). Figure 34.

You can view the details of VMs online and VM LUN path information, as shown in Figure 35. Figure 35. Virtual Machines Properties dialog box Brocade Data Center Fabric Manager (DCFM) 45 of 50

46 Unified Management of SAN and HBA/CNA Brocade is delivering on the promise for unified fabric management. Since Brocade develops FC HBAs and FCoE/CEE CNAs, integration with Brocade Host Connectivity Manager (HCM) is possible for all models of Brocade FC HBAs (415 and 425 in addition to the 815 and 825), and the following features are introduced in DCFM 10.3: Host-based discovery and topology views include discovery of Brocade HBAs/CNAs, shown in Figure 36. Figure 36. Host-based Topology view Automatic server-to-hba mapping Properties display Events integration Statistics collection and display including Real-Time Performance Monitoring, shown in Figure 37.

47 Figure 37. Real Time Port Selector window End-to-end switch and HBA configuration operations Instead of having to go to the HBA element manager first to configure FCSP and then to the switch element manager to configure the same parameters on the switch port, you can configure both ends of the connection (HBA port and its corresponding switch port) in a single operation from DCFM. Figure 38. FCSP (Fibre Channel Security Protocol) Authentication dialog box HBA supportsave: host management supports capturing support information for managed Brocade HBAs, which are discovered in the management application. You can trigger SupportSave for multiple HBAs at the same time. Deep element management HCM Launch-in-Context from DCFM With a single user interface to manage all HBAs, storage and server administrators can manage local HBAs (HBAs installed on same machine as GUI) as well as remote HBAs (HBA installed on distributed servers).
