10 Architecture overview This section summarizes the architecture and configurations we used in the Vblock Solution for Exchange and SharePoint. Microsoft Exchange Exchange consisted of Client Access server (CAS), Hub Transport server (HUB), Mailbox server (MBX), and Active Directory. The Vblock System 200 was optimal for the storage, compute, hypervisor, and network requirements of this solution. This enabled us to attain a more consolidated deployment of Exchange and SharePoint components across all five physical ESXi hosts on a Vblock System 200, by deploying six virtual machines (VM) on ESXi hosts 1 and 2 and six VMs on ESXi host 3 and 4, for a total of 12 VMs on four physical servers. Each ESXi host runs on a Cisco C220 M3 server and is connected through 2 Nexus 5548 SAN Fabric Switches to the VNX 5300 storage array. Microsoft SharePoint We deployed SharePoint in a three-tier architecture: Web front ends (WFE) Application servers (APP) Crawl (CRAWL), Query (QUERY), and SQL servers Table 1.

13 Design considerations This section describes the design considerations we used in the Vblock Solution for Exchange and SharePoint. Storage The disk layout was based on Microsoft and EMC best practice recommendations. Disk and pool layout The VNX storage platform used in this solution provides consolidated access to stored data from multiple hosts, users, and applications by using existing IP network and connectivity, and industrystandard protocols, including CIFS, NFS, and iscsi. Using RAID, the array can automatically rebuild a faulted drive to a spare drive. After the RAID group member is rebuilt, the group is resilient to a single disk failure. This solution, based on the VNX platform, allows organizations to store and protect files, folders, and application data at a low cost of ownership while meeting enterprise requirements for scalability, protection, and availability. Application resources Microsoft Exchange We used two Mailbox servers with the following thin devices in each: Four 1.6 TB database LUNs Four 100 GB log LUNs We used two HUB/CAS servers with one 300 GB thin device in each. We configured RAID 10 group for databases and logs, hosting 16 Raw Device Mapping (RDM) disks for Exchange resources. Microsoft SharePoint We used 200 GB for each content database. We divided 1.2 TB of user data comprising 4,800,000 documents into 6 x 200 GB content databases on 300 GB volumes, which we spread across 16 x 600 GB disks using RAID 5 for redundancy. All VMs used the VNX5300 for operating systems and content databases. We used RAID 1/0 LUNs for the search and TempDB databases. We deployed the VNX 5300 as a performance pool using 44 x 600 GB SAS 10 K RPM disks hosting 6 VM disks (VMDK) for SharePoint resources VCE Company, LLC. All Rights Reserved. 13

14 We limited VMDK sizes to the following guidelines to improve SharePoint management and performance: Microsoft strongly recommends limiting content databases to 200 GB. A site collection should not exceed 100 GB unless it is the only site collection in the database. Content database sizes up to 1 TB are supported only for large, single-site repositories and archives in which data remains reasonably static. Table 5.

Although not used in this solution validation, you can also create database availability groups to improve availability. Microsoft Exchange server roles, subsystems, and sizing The Exchange server roles we used in this solution are Mailbox, Hub Transport, and Client Access. We virtualized all Exchange server roles using ESXi 5.0. Table 10 shows the different Exchange server roles, their respective subsystems, how we sized them VCE Company, LLC. All Rights Reserved. 16

17 Table 10. Exchange server roles, subsystems, and sizing Roles Subsystems Sizing (per the Microsoft Mailbox Server Role Requirements Calculator) MBX Processor The megacycles required per mailbox are 3. The megacycles required for a four-core Mailbox server are 8,250. The specint2006 ratio for the C220 M3 blades is estimated at 697, based on the Intel Xeon ES-2690 processor architecture. We factored 10% processor overhead into the overall requirements to compensate for the hypervisor overhead, per VMware guidance. With this configuration, the server would run at 24 percent utilization. Storage The role calculator recommends 44 x 2 GB 7.2K SATA drives to meet the I/O requirements of 5,000 users with 150 messages sent/received per mailbox per day, with a 2 GB mailbox quota. Single-item retention and calendar version storage are included in this calculation. The IOPS per mailbox is No IOPS or disk capacity buffer are included. RAID 1/0 was the best fit for capacity and I/O with this configuration. Memory The amount of database cache required per mailbox is 9 MB. The amount of memory required per server is 32 GB. Summary 4 vcpus 32 GB RAM 4 x 1.6 TB database LUNs 4 x 100 GB LOG LUNs 1 virtual network interface card Notes The backup and restore of Exchange, outside of a JetStress test, is not covered in this solution architecture. EMC has a proven and documented backup and restore solution using the Replication Manager. HUB/CAS Processor We used a 1:1 ratio for Mailbox cores to combine Hub Transport and Client Access cores. We used 8 Mailbox cores with 8 Hub Transport and Client Access server cores. Storage Memory The Client Access role does not consume much storage space, and does not require a precise amount of IOPS or capacity. The Hub Transport role does have this requirement, based on the message volume per day to determine the IOPS and capacity required. We used 8 GB of memory for every processor in the system. Summary 4 vcpus 32 GB RAM 2 virtual network interface cards Notes Hardware or software load balancing was not used at the CAS tier in the solution testing. Although a real Exchange solution would include this, it is outside the scope of this solution testing.

18 Microsoft SharePoint Search SharePoint search architecture is made up of the crawler, index server, query server, and user interface and query object model. We used central administration to create a new SharePoint search service application. We set up content crawl rules, indexes, and content databases. We used WSS_UsageApplication Service Application to manage web analytics, such as usage, search query usage, and rating usage. In our solution, we deployed the query server on the WFE layer and the crawl server on the application layer to optimize search performance. When a user sends a search request to the SharePoint search site, the search request is sent by the load balancer to the WFE layer, where the query server is located. The query server thus processes the search query on the same layer, which reduces latency. The crawl server retrieves information from the content databases and indexes it. The crawl server then sends the index to the WFE server, where the query is processed. Figure 2. Optimized SharePoint search performance 2013 VCE Company, LLC. All Rights Reserved. 18

19 Databases Disk throughput requirements for content databases can vary significantly between implementations. Microsoft recommends matching your expected workload to one of their tested solutions. For more information, refer to Performance and Capacity Test Results and Recommendations (SharePoint Server 2010 and Exchange Server 2010) at technet.microsoft.com. Table 11. Content database configurations Database Configuration Content We designed the solution according to industry standards, as a publishing portal with 1.2 TB of user content comprising six SharePoint site collections or document centers. This configuration was based on the Microsoft recommendation to use smaller LUN sizes to reduce latency: We populated each SharePoint site with 200 GB data on 300 GB LUNs, which addressed the anticipated content database, file growth caused by SQL rebuilds and SharePoint sprawl. We used 50 GB log files on 100 GB LUNs, which addressed the anticipated rapid growth in database log files caused by modifications and binary large object uploads. We placed the content databases on RAID 5 LUNs to handle anticipated lower I/O operations. We reduced the content index files by partitioning the query server index across 2 RAID 5 LUNs, which allowed for better redundancy. TempDB We placed the TempDB databases on RAID 10 LUNs, per Microsoft SQL Server 2008 best practices in order to achieve higher IOPS. Search We placed the search databases (property store and crawl store) on RAID 1/0 LUNs to handle anticipated higher I/O operations. We allocated each of the search databases a 200 GB LUN, constituting 10% of the total content, in order to allow for growth. Crawl We placed the crawl server index on RAID 5 LUNs, because they only hold incremental data and are therefore much smaller than in SharePoint 2007 implementations typically only a few gigabytes for a 1 TB content database VCE Company, LLC.

20 Intel Hyper-Threading technology Hyper-Threading Technology (HT) is Intel s proprietary simultaneous multithreading implementation, which improves the performance of computers performing multiple tasks in parallel. According to Microsoft s recommendations for Exchange, HT can challenge capacity planning and monitoring for what is a small gain in CPU overhead. We recommend disabling HT on the Exchange ESXi host and only enabling it as a temporary measure to increase CPU capacity until you obtain additional capacity. For more information, refer to HyperThreading Considerations for Exchange 2010 at technet.microsoft.com/. We used HT for the SharePoint portion of this solution. Deployments This solution allows you to accelerate deployment by making clones for web, application, SQL, Client Access, Hub Transport and Mailbox servers for Exchange and SharePoint across multiple locations, which eliminates the need to manually redeploy your environment. Scalability Managing Exchange and SharePoint growth is an inevitable challenge. For Exchange and SharePoint deployments for more than 5,000 users, you can easily add compute and storage resources to the Vblock System 200 used in this solution validation. Vblock Systems support upgrading Cisco UCS blades within a rack to help manage CPU and memory performance during growth cycles. VNX storage platform supports high-performing Serial Attached SCSI (SAS) drives and cost-effective nearline (NL) SAS drives that combine the convenience of an SAS interface with the economy of serial ATA (SATA) drives. Many customers combine SAS and NL SAS drives for optimum cost and performance, providing a dynamic storage strategy that suits many business and technology requirements. We overprovisioned the memory for this solution to demonstrate that the Vblock System 200 provides ample room for future growth. Your business requirements, including growth plans, will determine your implementation requirements VCE Company, LLC. All Rights Reserved. 20

21 Solution validation This section describes how we validated the Vblock Solution for Exchange and SharePoint. Applications We used the industry standards, EMC Unisphere, Microsoft Exchange Server JetStress 2010, Microsoft Exchange Load Generator 2010, and HP LoadRunner 11.0, to validate the physical and logical configurations of the Vblock Solution for Exchange and SharePoint. We validated this solution per Microsoft s guidelines for Exchange and SharePoint Heavy Users, Microsoft SharePoint guidelines for Acceptable User Response Times, and relevant industry standards. EMC Unisphere Unisphere provides a simple integrated tool for the VNX for provisioning and managing VNX storage arrays. HP LoadRunner 11.0 LoadRunner is an automated performance and test automation product from Hewlett-Packard for examining system behavior and performance under load by emulating thousands of concurrent users to apply production workloads to your environment. Microsoft Exchange Server JetStress 2010 JetStress works with the Exchange database engine to simulate the Exchange database and log disk I/O load. JetStress uses the Exchange Storage Engine to validate that your storage array meets the IOPS requirement for Exchange. To ensure you have the correct Exchange Storage Engine, verify that it is compatible with the version of JetStress you have, and only use it to validate the actual server you intend to use for your Exchange deployment. Note: Run JetStress to validate your IOPS requirements before installing Exchange. Microsoft Exchange Load Generator 2010 LoadGen is a simulation tool used to measure the impact of MAPI, OWA, IMAP, POP, and SMTP clients on Microsoft Exchange Server 2010 servers. LoadGen tests the client-facing components of the Exchange solution and tests the compute, storage, and network components of the Exchange infrastructure. LoadGen creates users, groups, Organizational Units, Exchange databases, and mailboxes, and executes workload testing against the Exchange Hub Transport server, Client Access server, and Mailbox server roles VCE Company, LLC.
