2 Executive summary As customers increasingly adopt Microsoft SharePoint 2010 to meet the collaborative needs of their businesses, HP continues to provide guidance on the successful infrastructure sizing and deployment of these solutions. This white paper explores the performance characteristics of HP ProLiant DL380p Gen8 servers in combination with HP StoreVirtual 4500 and the HP G al Switch as they relate to a typical collaboration deployment with SharePoint 2010 and Microsoft SQL Server You have many choices when it comes to the underlying hardware for solutions, which is why HP strives to be the vendor of choice by constantly testing and understanding the needs of these solutions, and helping you deploy them correctly the first time. Target audience: Individuals or groups seeking guidance on the appropriate sizing and deployment of SharePoint 2010 on the latest generation of HP ProLiant servers, HP networking solutions, and HP Storage. This white paper describes testing performed in October Introduction SharePoint 2010 is one of the most prolific collaboration platforms available today, allowing people to work together in ways that best suit your business needs. However, this platform can be difficult to correctly size and deploy; as a result, HP offers guidance based on actual test results, allowing you to better understand the requirements of a SharePoint 2010 solution and the impact it may have on your existing infrastructure. The performance testing outlined in this white paper was designed to replicate typical workloads you might encounter when deploying SharePoint 2010 on HP products such as ProLiant Gen8 servers, HP Storage, and HP networking solutions. However, because SharePoint 2010 can be deployed and configured in many different ways, your results may vary depending on actual workloads and differences in configuration. The configuration described in this paper should not be considered to be the only configuration recommended by HP for SharePoint 2010 deployments; rather, it is just one particular solution. Important While this testing can provide a benchmark to be used for comparing hardware and/or software products, it is not intended to serve as a sizing guideline. In the real world, server performance is highly dependent upon application design and workload profiling. As with any laboratory testing, the performance metrics quoted in this paper are idealized. In a production environment, these metrics may be impacted by a variety of factors. As a matter of best practice for all deployments, HP recommends implementing a proof-of-concept using a test environment that matches as closely as possible the planned production environment. In this way, appropriate performance and scalability characterizations can be obtained. For help with a proof-of-concept, contact an HP Services representative or your HP partner. Test topology The benchmark testing described in this paper explores the performance characteristics of the DL380p Gen8 server in combination with HP StoreVirtual 4500 and an HP G al Switch when used in a typical collaboration deployment with SharePoint 2010 and SQL Server Two DL380p Gen8 servers were used, each configured with two Intel Xeon E CPUs, 192 GB of RAM, and two local hard drives (HP 300GB 6G SAS 15K rpm small form factor (SFF) enterprise hard drives). SharePoint 2010 was installed on one server typically known as the web front end (WFE); SQL Server 2012 was installed on the second server. An HP StoreVirtual 4500 was connected to the SQL Server machine to provide storage for the content database. 2

3 All systems were connected via 1 Gb network links provided by an HP G al switch, isolating the following traffic on to separate physical connections: Clients WFE WFE SQL Server SQL Server HP StoreVirtual 4500 This type of isolation, which is considered by HP to be a best practice for a SharePoint 2010 deployment, also allows you to accurately gauge the level of traffic between tiers. Figure 1 illustrates the tested configuration. Figure 1. Architectural diagram of solution HP G al Switch HP ProLiant DL380p Gen8 Server HP ProLiant DL380p Gen8 Server Web Front End SQL Server 2012 HP StoreVirtual 4500 Test methodology In order to properly test this or any other SharePoint 2010 deployment, you should emulate actual users that are performing typical tasks in the way a real user would interact with SharePoint 2010 sites. This involves the following activities: Logging on to and manipulating a SharePoint 2010 site Uploading and downloading content Making changes to site data Performing tasks that change the site In order to achieve this type of workload, HP LoadRunner, an industry standard for application performance testing, was used. HP LoadRunner HP LoadRunner can emulate hundreds or thousands of concurrent users and apply workloads to almost any client platform or environment. By applying consistent, measurable, and repeatable loads, LoadRunner stresses an application from end to end, providing test results that can be used to identify scalability issues that might affect real users in a production environment. In this particular testing, HP engineers used the web protocol within LoadRunner s Virtual User Generator (VuGen) to record several different types of activities. The resulting scripts were then combined, modified, and parameterized to apply to a multiple-user SharePoint 2010 environment. 3

4 The workload created known as the SharePoint 2010 enterprise collaborative workload was representative of a typical collaborative environment and was designed to test against a range of web applications, each stressing a different aspect of the SharePoint 2010 deployment. User decision points were incorporated throughout the testing. For example, the division between web applications was as follows: Document Center (DocCtr) 30% Team Sites (TeamSite) 20% Portal Site (Portal) 20% Mysite (MySite) 10% Search (Search) 20% Timing was also an important consideration. Each particular task, such as opening an item or navigation, resulted in a wait time of one to four seconds to emulate a user reading the content being rendered. Response times (excluding the emulated wait times) for each task were recorded and were used to judge the responsiveness of the deployment. Each web application is outlined below. Document Center Users logging on to a document center are expected to perform tasks that are focused on document collaboration and management. Thus, this workload emulates users checking out, changing and uploading, and checking in a document. Versioning is turned on, and limited to three major versions. With every check in, a new version is created and stored within the content database. Users in the document center are also expected to manage tasks in a task list. They read, create, and delete these tasks, also causing change within the content database for this web application. User decision points are driven randomly, with the user working with documents 75% of the time and working with tasks 25%. Team sites The initial deployment of the Team Sites web application creates 25 different team sites. A user logging on to the Team Sites host site randomly chooses a team site to work in. The workload includes the following areas: Discussion threads (50%) The user navigates to a pre-populated thread, reads the thread, and then, 30% of the time, creates a response Calendar (20%) The user either reads existing calendar entries (50% of the time) or creates new entries (50% of the time) Document management (30%) The user uploads a Microsoft Office Excel file to the document library of the particular team site Portal Site The Portal Site web application is designed to emulate users hitting a corporate portal page that contains a lot of static content. This workload includes the following areas: Events (40%) The user navigates to a specific list and reads a pre-populated entry Announcements (40%) The user navigates to a specific list and reads a pre-populated entry Survey (20%) The user navigates to the survey application and randomly chooses an answer to a survey Mysite Introduced as the foundation for corporate social media in SharePoint 2010, the Mysite feature allows users to have their own personal location on the SharePoint site. Here they can store files and develop a taxonomy based on their expertise (as specified within metadata contained in their files). For this web application, users log on to their own mysite and upload a document containing pre-generated metadata. Search Since a key component of any SharePoint 2010 deployment is the ability to find relevant information, the following search functionality is important: Content indexes Created by crawling the site s content Taxonomy Created from user information and metadata contained within the site s content 4

5 During the setup phase of the testing, a rich, deep taxonomy was created by uploading over 5 GB of documents that were pre-populated with metadata and assigned to the existing user base. Thus, after logging on to the Search web application, the user can perform a search based on the known list of metadata tags that were used to create the documents. The resulting search contains documents matching the metadata tags along with the users associated with the particular documents. 25% of searches result in a file being directly downloaded from the document center. Test results Tests results are provided for the following: Response times WFE CPU performance Back-end CPU performance Network consumption For more information on the performance counters used, refer to Appendix A. Response times 250 concurrent users were utilized to characterize the performance of the HP products used in this SharePoint 2010 solution. Note In a SharePoint environment, you can think of the number of concurrent active users as being a small percentage of the entire user base. For a collaboration workload, this percentage is widely accepted to be 10%; thus, if you have 250 concurrent active users as in the test environment, the user base for the solution would be around 2,500. Of course, this percentage can vary widely in real-world environments based on the type of work that is actually being performed. Table 1 summarizes transaction times for activities within the various web applications. These times were extracted from a time span of 60 minutes, starting one hour after the beginning of user ramp-up and ending before user ramp down began. This time span was steady-state, with all users logged on and working. Table 1.

The wide variation in file upload and download times can be attributed to differences in document size and on random decisions concerning which files to transfer. 6

7 WFE CPU performance To understand how each of the solution tiers was performing, HP analyzed records from a broad range of performance counters. Figure 2 shows CPU performance in the DL380p Gen8 server used for the WFE tier. Figure 2. WFE CPU consumption The WFE consumed an average of 28.5% of available CPU resources, with peaks up to 47%. At the same time, SharePoint 2010 was committing 18 GB of RAM and requiring an average of 29.5 IOPS. To put this in perspective, clients were recording 1,500 hits per second while ASP.net counters were reporting 1,000 requests per second. On average, 82 total transactions per second were being completed. 7

8 Back-end CPU performance Figure 3 shows CPU performance in the DL380p Gen8 server used for the SQL Server solution tier. Figure 3. SQL Server CPU consumption On average, SQL Server consumed a mere 3.9% of available CPU resources, with peaks up to 8.5%. SQL Server cached all of the content databases and was committing 44 GB of RAM. The average IOPS value was 1,037, with peaks to 2,580. The majority of I/Os were write, which was not surprising given that SQL Server had cached all the content databases. SQL Server maintained an average write throughput of 50 MB/s, with an average disk queue length of 42. 8

9 Network consumption Figure 4 illustrates network consumption at the HP G al switch. Figure 4. Network consumption for the entire solution The red line denotes client WFE traffic, which averaged 470 Mb/s, with peaks to 648 Mb/s. The blue line denotes WFE SQL Server traffic, which averaged of 410 Mb/s, with peaks to 734 Mb/s. Given that each of these connections is support by a 1 Gb/s link, network consumption is a potential area for concern. Test analysis summary Deploying SharePoint 2010 can be a complex and sometimes daunting task. Failure to understand how SharePoint 2010 performs, the requirements made on the underlying hardware, and the impact the solution may have on the existing infrastructure can result in a poor implementation with long-term performance implications. The testing described in this white paper can be used to identify the following key focus areas for a SharePoint 2010 deployment: Networking SharePoint 2010 relies heavily on networking connectivity between clients and the multiple tiers of the solution and, without careful planning, could quickly consume these networking links. Thus, when deploying SharePoint 2010, you should seriously consider its impact on your current networking infrastructure and, if appropriate, implement higher speed connections to the data center. HP offers a wide selection of networking equipment designed to support the 10 Gb/s links that are highly recommended for larger SharePoint deployments. SQL Server tier Performance on the SQL Server tier in a collaboration deployment for SharePoint is more dependent on memory size and I/O throughput than on CPU resources. In this particular solution, for example, the SQL Server tier consumed large amounts of RAM and IOPS while barely exercising the CPU capabilities of the DL380p Gen8 server. Given that the new pricing model for SQL Server 2012 is dependent on the number of available cores, a single-socket, six-core version of this server might be more appropriate for an actual deployment. Additionally, given the IOPS load at this level, you might consider larger, more robust HP Storage when taking into account growth and variations in workload. WFE The tested workload consumed less than half of the CPU resources available in the WFE tier, leaving more than 50% of the server s computational abilities idle. To increase resource utilization, you could downgrade the server to a single-socket solution, which would also reduce the up-front cost of the solution. 9

10 High availability (HA) Although it was not built into the deployment described in this white paper, HA should always be a primary concern in mission-critical environments. For SharePoint 2010, one method recommended for achieving HA is to double the server hardware, create a Windows failover cluster for SQL Server, and use Windows load balancing for WFE roles. Disaster Recovery (DR) Hand in hand with HA, you should also consider how to get your solution back up and running following a disaster. While there are many options for achieving DR in a SharePoint 2010 deployment, your particular choice will depend on a balance between cost and the amount of downtime you are willing to bear. HP Services can provide guidance on these options and provide recommendations tailored to meet your individual needs. Virtualization Given the nature of the test results described in this white paper, you may wish to explore the possibility of virtualizing this environment to make more efficient use of your hardware resources. Planned white papers from HP will cover the virtualization of this workload so as to provide a more cost-effective solution that better utilizes your investment in HP ProLiant servers. Recommendation Customers considering deploying SharePoint 2010 within an existing infrastructure should not only analyze the hardware requirements of the deployment but should also consider how a SharePoint solution might affect the existing infrastructure. SharePoint 2010 can consume large amounts of network capacity, potentially resulting in a bottleneck that can affect not only the SharePoint deployment but all other solutions relying on network throughput. Additionally, in the case of SharePoint, when the expected network consumption begins to increase, you may need to investigate the amount of data sprawl and the storage needed to contain it. SharePoint deployments tend to grow in size and scope over time as the user community finds new and different ways to incorporate it into their daily work routines. As a result, you should not only focus on the solution being deployed but also on how this solution may evolve over time so that you can plan for growth. HP provides a wide range of products and services to help you get the most from your SharePoint investment, including the HP Sizer for Microsoft SharePoint 2010 a free tool from HP that allows you to accurately size the hardware needed for your SharePoint 2010 deployment.
