Chapter 1. Planning for installation Read about deployment considerations and system requirements for Network Manager. Deployment of Network Manager Use this information for guidance on how to configure the physical deployment of your Network Manager installation. Deployment scenarios How you deploy Network Manager depends on your enironment, including factors such as the size and complexity of your network and the number of operations staff who require system access. The following are typical Network Manager deployment scenarios: Small demonstration or educational system deployment Small customer network Medium customer network Large customer network Very large customer network A further deployment scenario is the following: Telecommunications company or serice proider network. Note: Failoer can be applied to each of these Network Manager deployments. This section proides general guidance to assist you in deciding how to deploy Network Manager. For more detailed information, see the IBM Tioli Network Manager IP Edition Installation and Configuration Guide and the IBM Tioli Network Manager IP Edition Release Notes. Network and deployment comparisons Use this information to compare the example customer networks and to compare the Network Manager deployments for each of the example customer networks. Customer networks compared: Use this information to compare the example customer networks and to identify which example most closely matches your network. The following table lists typical features for each of the example customer networks. These alues are example alues only. Your specific network alues might ary. In particular, you should note the following: With regard to the alues for Aerage number of interfaces per deice specified in this table, the actual interface counts can ary considerably from the aerage interface count. An example of this is found in MPLS networks, where the number of interfaces per deice is ery high in the core network, but might be as low as 2 to 3 interfaces per deice for the edge deices. With regards to the number of deices for a telecommunications company, the alue specified (15,000) is an aerage alue. A national telecommunications Copyright IBM Corp. 2006, 2013 1

You might need to partition your network into multiple domains for one of the following reasons: Your network exceeds a certain size. See the section Guidelines for number of network domains to determine whether your network requires multiple domains. Discoery takes a ery long time. You can shorten your discoery times by partitioning your network into multiple domains. Operational boundaries dictate the need for multiple domains. Examples of operational boundaries include geographical boundaries and security boundaries. Your network contains oerlapping IP addresses. Guidelines for number of network domains: If your network exceeds a certain size, you might need to break up the network into multiple domains. Use this information to work out the number of network domains needed for your deployment. Use the following procedure to determine the number of required domains. For information on how to create and configure extra network domains, see the IBM Tioli Network Manager IP Edition Installation and Configuration Guide. Note: The calculations presented here proide approximate figures only. The actual number of domains required aries, depending on arious factors, including the agents used in the discoery. For example, the Entity agent discoers a lot of extra network entities, and this might require more domains. 1. Gather the following data: Chapter 1. Planning for installation 3

Number of deices in the network Aerage number of interfaces per deice Note: The actual interface counts on a gien deice can ary considerably from the aerage interface count. An example of this is found in MPLS networks, where the number of interfaces per deice is ery high in the core network, but might be as low as 2 to 3 interfaces per deice for the edge deices. 2. Apply the following equation to determine an approximate number of network entities: Number of network entities = Number of deices * Aerage interface count * multiplier Where: multiplier = 2 for a routed network multiplier = 3.5 for a switched network Note: Switched networks tend to generate more network entities because they contain VLANs, which contain multiple entities. 3. Apply the following equation to determine the suggested number of network domains: Number of domains required = (Number of network entities) / 250,000 Where 250,000 is the suggested maximum number of network entities in a domain. Router-centric customer The data for this customer is as follows: Number of deices in the network: 15,000 Aerage number of interfaces per deice: 20 This customer network will produce approximately 600,000 network entities: Number of network entities = 15,000 * 20 * 2 = 600,000 Based on the following calculation, this network requires three network domains: Number of domains required = 600,000 / 250,000 = 2.4 Switch-centric customer The data for this customer is as follows: Number of deices in the network: 1,000 Aerage number of interfaces per deice: 24 This customer network will produce approximately 84,000 network entities: Number of network entities = 1,000 * 24 * 3.5 = 84,000 Based on the following calculation, this network requires one network domain: Number of domains required = 84,000 / 250,000 < 1 4 IBM Tioli Network Manager IP Edition: Installation and Configuration Guide

Related concepts: Network domains on page 20 Before installing, you need to consider whether to partition your network into domains, or hae a single domain for the entire network. A network domain is a collection of network entities to be discoered and managed. Demonstration or educational system deployment This is a small installation for use as a demonstration system or for training and educational purposes. The following sections describe this network in greater detail and proide suggestions for a Network Manager deployment to meet the needs of this network. Description This enironment consists of about 25 network deices and key serers combined. All deices are in one location, on the same network subnet as the deices to be managed. There is one local GUI client session supported by the same machine that hosts the Network Manager product components. There might be one or two GUI client sessions on other machines. The network deices come from multiple endors. The network architecture is flat. All deices are attached to a LAN and hae Fast Ethernet connections. For demonstration purposes only, a number of network deices hae SNMP3, and a number of workstations hae IP6. Within this enironment the following example conditions apply: 1 to 3 actie GUI clients. Chassis ping polling and some SNMP polling actiity is required. No major Tioli products are integrated with the system, other than the required Tioli Netcool/OMNIbus. Performance reports are required for short data collection periods (typically 1 to 5 days) to match the length of the training course. Network Manager deployment A single-serer deployment is sufficient for this type of enironment. In addition to the single-serer deployment description proided elsewhere, the following deployment settings are appropriate for this type of enironment. System is an entry workstation class machine, with 4 to 6 GB of memory, dual-core processor preferred, single-core acceptable, reasonable current processor speed, and Fast Ethernet capability. IP6 dual stack support is required if workstations or network deices hae IP6. Default database used for the NCIM database. Client system: single processor, 3 GB of memory, supported JRE and Internet browser Chapter 1. Planning for installation 5

Small customer network This customer is a company with a network consisting of about 150-300 network deices and key serers. The purpose of this installation is to manage this customer network by alerting the operations staff to major failures. The following sections describe this network in greater detail and proide suggestions for a Network Manager deployment to meet the needs of this network. Description The primary users of the product are the networking operations staff. All deices are in one location and managed by a small operations group of a few people. Network deices come from multiple endors. A mixture of layer 2 and layer 3 network deices are present. Approximately 20 to 30 VLANs are defined. The network architecture is fairly flat and simple. All deices to be managed are located in the same network as the Network Manager system and hae Fast Ethernet connections. Internet connections are passed through a firewall and access to the systems within the protected network is aailable through a company VPN. The network operations staff hae clients attached by means of one of the following: a local LAN, WiFi connections, or by means of a VPN established by a telecommunications serice proider. Network changes are made once a month and a new discoery is anticipated at this time. Within this enironment the following example conditions apply: 3 actie GUI clients. Chassis ping polling at two-minute interals. SNMP polling at 30 minute interals. Typically three to 6 SNMP MIB alues require polling. No major Tioli products are integrated with the system, other than the required Tioli Netcool/OMNIbus. Performance reports are required for data collection periods on the order of 31 days. Network Manager deployment A single-serer deployment is sufficient for this type of enironment. In addition to the single-serer deployment description proided elsewhere, the following deployment settings are appropriate for this type of enironment. A single network domain is sufficient for this size of network. System can be any of the supported platforms. System requires 6 to 8 GB of memory, dual-core processor, and multiple physical disks in RAID 5 configuration. Client system: single processor, 3 GB of memory, supported JRE and Internet browser Default database used for the NCIM database. A single ncp_poller polling engine is sufficient for this enironment. 6 IBM Tioli Network Manager IP Edition: Installation and Configuration Guide

Medium customer network This customer is a company with a central major data center and connections to seeral remote sites. The purpose of this installation is to manage this customer network by alerting the operations staff to major failures. The following sections describe this network in greater detail and proide suggestions for a Network Manager deployment to meet the needs of this network. Description This network has between 250 and 1000 network deices and key serers of interest. Workstations, while numbering in the thousands, are not managed. Network deices come from multiple endors. All deices in the central location hae Fast Ethernet or Gigabit Ethernet connections. Remote sites are connected by WAN connections. The deices and serers to be managed are distributed among the central and remote sites. Within this enironment the following example conditions apply: There are 5 to 20 actie GUI clients. Chassis ping polling at two to fie-minute interals. SNMP polling at fie to 15-minute interals. Other major Tioli products integrated with the system, other than the required Tioli Netcool/OMNIbus: IBM Tioli Monitoring with Tioli Data Warehouse running DB2 to support performance reporting. Performance reports are required for data collection periods on the order of 31 days. Network Manager deployment Each customer enironment with this kind of network is different. The key to success is adequate memory and a careful understanding of the polling targets, combined polling rates, and the eent rates. Based on these considerations, a single-serer deployment or a two-serer deployment is sufficient for this type of enironment. The following deployment settings are appropriate for this type of enironment. One or two network domains are required, depending on the size of network. Single serer deployment (up to 250 network deices and 5 to 10 concurrent users) Four processors 8 to 10 GB memory Multiple physical disks in RAID 5 configuration Two-serer deployment (up to 1000 network deices and 10 to 20 concurrent users) Four processors for system with Network Manager Four processors for system with Tioli Netcool/OMNIbus and Tioli Integrated Portal 8 GB memory for each serer Multiple physical disks in RAID 5 configuration System may be any of the supported platforms. Client system: single processor, 3 GB of memory, supported JRE and Internet browser Any supported RDBMS used for the NCIM database. Chapter 1. Planning for installation 7

Number of polling engines: Single-serer deployment: 1 Two-serer deployment: One poller for chassis pings, two or more pollers for SNMP polls Large customer network This customer is a large enterprise company with a globally deployed network. The purpose of this installation is to manage this customer network by alerting the operations staff to major failures and to support the latest network deices and network architecture. The following sections describe this network in greater detail and proide suggestions for a Network Manager deployment to meet the needs of this network. Description The architecture of the network is complex. and contains the most up to date technology. For example, the network contains MPLS core networks. The network deice count ranges from 1,000 to 12,000 deices, and the complexity of the network is reflected in the fact that there are 30 or more ports per deice on aerage. Network operations are done from a central location with operations staff constantly monitoring the core network. Network deices come from multiple endors. Within this enironment the following example conditions apply: There are typically 5 to 20 concurrently actie GUI clients. Polling: Chassis ping polling at two to 5 minute interals. SNMP polling at 10-15 minutes. SNMP3 polling of key network deices SNMP1 polling for real time graphing as well as storage for performance reports. Other major Tioli products integrated with the system, other than the required Tioli Netcool/OMNIbus: IBM Tioli Monitoring (ITM) with Tioli Data Warehouse (TDW) running DB2 to support performance reporting. IBM Tioli Business Serice Manager (TBSM) IBM Tioli Application Dependency Discoery Manager (TADDM) Performance reports are required for data collection periods on the order of 31 days. Network Manager deployment Deployment choices ary depending on the size of the network. For the 1000 deice network in this customer range, the choice ranges from a single-serer to a two-serer deployment. Key factors for success include the network response time for the targets (gien that this is a county or global distribution of target deices), memory aailability on the supporting serers, the polling selected and the rates of polling. 8 IBM Tioli Network Manager IP Edition: Installation and Configuration Guide

For the top end of the network (approximately 12,000 deices), a distributed, multiple domain deployment is required. In addition to the multiple-serer deployment description proided elsewhere, the following deployment settings are appropriate for this type of enironment. Deploy two domains with two serers for each domain. Deployment of a dedicated database serer might be required. Each of the serers requires the following: Four processors. 8 GB of memory. 3 disk, RAID 5 multiple disk array For the systems used for each domain, deploy as follows: Serer 1: Network Manager Serer 2: Tioli Netcool/OMNIbus and Tioli Integrated Portal System 3 (optional): a customer-selected RDBMS supporting both domains Systems to be deployed on Linux or UNIX platform. Any supported RDBMS used for the NCIM database. Two polling engines: Use the default ncp_poller process for chassis ping. Create a separate ncp_poller for the SNMP polls. Client system: single processor, 3 GB of memory, supported JRE and Internet browser Very large customer network This customer is a ery large global enterprise company with a simple network architecture but ery large numbers of deices. The purpose of this installation is to manage this customer network by alerting the operations staff to major failures and to support short-term capacity planning. The following sections describe this network in greater detail and proide suggestions for a Network Manager deployment to meet the needs of this network. Description Network management is done from a central location and from regional locations. The network is ery large and contains oer 12,000 network deices and critical serers. Network deices come from multiple endors. The deices fall into two categories: Network deice infrastructure with interface counts in the range of 30 or more per deice. Managed deices with 1-2 interfaces per deice. The majority of the deices are in the second category, managed deices. To manage a network of this size, the network is partitioned for management on a geographical basis. Within this enironment the following example conditions apply: There are 5 to 20 actie GUI clients. Polling: Chassis ping polling at two to 5 minute interals. SNMP polling at 15 minutes or longer.

SNMP1 data collection Other major Tioli products integrated with the system, other than the required Tioli Netcool/OMNIbus: IBM Tioli Monitoring (ITM) with Tioli Data Warehouse (TDW) running DB2 to support performance reporting. IBM Tioli Business Serice Manager (TBSM) IBM Tioli Application Dependency Discoery Manager (TADDM) Performance reports are required for data collection periods on the order of 31 days. Network Manager deployment Assistance from an experienced IBM serices group or qualified IBM business partner is highly adisable for a successful deployment. Multiple domains are needed, supported by a collection of indiidual serers, or running together on a ery large system. After completing a surey of the network to be managed, break the network up into sections that yield about 250-300K network entities, and then assign each of these sections be to a domain. In addition to the multiple-serer deployment description proided elsewhere, the following deployment settings are appropriate for this type of enironment. Multiple network domains. Platform selections: Linux and UNIX. Large systems (many processors and ery large amounts of memory) can host multiple domains as long as the memory allocations and processor counts are acceptable. Memory: 8-12 GB per domain Processors: 4-8 per domain depending on workloads Any supported RDBMS used for the NCIM database. Two polling engines for each domain: Use the default ncp_poller process for chassis ping. Create a separate ncp_poller for the SNMP polls. Indiidual process memory limitations are a factor in this enironment. Client system: single processor, 3 GB of memory, supported JRE and Internet browser Telecommunications company network This customer is a telecommunications company and internet serices proider. The purpose of this installation is to manage this customer network by alerting 24x7 network operations center staff to major failures. The following sections describe this network in greater detail and proide suggestions for a Network Manager deployment to meet the needs of this network. Description The network to be managed has about 300 network deices; with an aerage interface count per deice of 15. This is an MPLS network, and consequently the network deices are large in terms of their interface counts and complexity. Network deices come from multiple endors. All deices are in one or more locations and are managed by a small network operations group. All deices to be managed are connected ia Fast Ethernet or Gigabit Ethernet. 10 IBM Tioli Network Manager IP Edition: Installation and Configuration Guide

Within this enironment the following example conditions apply: Number of simultaneous actie clients: 5-20. Polling requirements: chassis pings at two to 5-minute interals; SNMP polling of 5 alues at 5 minute interals. Some SNMP3 polling is in place. Other major Tioli products integrated with the system, other than the required Tioli Netcool/OMNIbus: IBM Tioli Monitoring (ITM) with Tioli Data Warehouse (TDW) running DB2 to support performance reporting. IBM Tioli Business Serice Manager (TBSM) IBM Tioli Application Dependency Discoery Manager (TADDM) Performance reports done once a day for key deices, used to assemble weekly capacity reports. Network Manager deployment A three-serer deployment is needed for this type of enironment. In addition to the multiple-serer deployment description proided elsewhere, the following deployment settings are appropriate for this type of enironment. One to two domains. A three-serer deployment is adised. System specifications: System 1: two to four processors, 6-8 GB of memory, two or more disks System 1 (where Network Manager is installed): four processors, 6-8 GB of memory, two or more disks. Note that beyond 4 processors or processor cores, the core clock speed and on-chip cache can be more important than additional cores. The general rule is as follows: select the fastest 4 cores before additional cores. System 2: two to four processors, 6-8 GB of memory, two or more disks System 3: database serer; processors, memory and disks selected by the DBA Any supported RDBMS used for the NCIM database. Two polling engines: Use the default ncp_poller process for chassis ping. Create a separate ncp_poller for the SNMP polls. Client system: single processor, 3 GB of memory, supported JRE and Internet browser Deployment considerations You can deploy your entire Network Manager installation on a single serer or as a distributed installation. During a Network Manager installation, you install the following four Network Manager components. Network Manager core This component consists of the core Network Manager processes: network discoery, polling, root cause analysis and eent enrichment. NCIM database This database stores topology data. Chapter 1. Planning for installation 11

Tioli Netcool/OMNIbus This component consists of the Tioli Netcool/OMNIbus eent management software. Many customers choose to hae a trouble-ticketing system integrated with Tioli Netcool/OMNIbus. Tioli Integrated Portal This component consists of the Tioli Integrated Portal user interface framework, together with the web applications. The objectie of the installation is to place these components on one or more serers. The following are typical Network Manager deployment configurations: Single-serer deployment Distributed deployment: two serers or more The factors that require an increased number of serers in a distributed deployment include the following: Actie eent rates Amount and rate of stored polling data Deice status polling rates and number of polling targets Network response times for polled targets Discoery frequency and Size of the network to be discoered (for each domain, where there are multiple domains) Note: These deployment configurations do not take into consideration requirements for other product integrations. In addition, you must consider deployment of appropriate systems to support GUI client sessions. Single-serer deployment Single-serer deployments are appropriate for small demonstration or educational systems, and for systems to support small to medium customer networks. A single-serer deployment must meet the following minimum specification: A minimum of two processors of current speeds, preferably four processors. Examples of current speeds include 3 GHz or better for processors from the Intel product line, and 1.6 GHz or better for processors from the Sun product line. A minimum of 6 GB of memory, preferably 8 GB. Distributed deployment: two serers or more In distributed deployments, Network Manager components are distributed across multiple serers, that is, two serers or more. Here are some guidelines for distributed deployments: Two-serer deployments are appropriate for the top end of the range of medium customer networks. Deployments might require three serers or more in situations where there are multiple network domains. 12 IBM Tioli Network Manager IP Edition: Installation and Configuration Guide
