Executive summary The new HP ProLiant BL3 5p two-way server blade delivers uncompromising manageability, maximu m computing density, and breakthroug h power efficiencies to the high-per formance data center.
Overview This section outlines the be nefits and key features of the HP ProL iant BL35p server blade, shown in Figure 1. Figure 1 : HP ProLiant BL35p s erver blade, showing a single blade and two blad.
Ideal environment Medium to large enterprise data center custom ers requiring dense two-way server performance • Maximum 32-bit or 64-bit two- way performance for load-balance d or front-end applic .
Performance testing HP continues to upgrade existing HP ProLiant server s and introduce new servers to meet particula r business needs. To help customers select th e appropriate server for their particular HP SBC environment, HP publishes this and other perfor mance briefs to characterize individual server performance and scalability.
More information on the test tools • Roboserver ( Robosrv.exe) and Roboclient (Robocli.exe): Terminal Server capacity planning • TSScaling: Windows Server 2003 Terminal Server Capacity and Scaling Test scripts HP used test scripts that simulate d the activities of three types of users (Heavy, Medium, and Light).
Test scenarios HP deployed the configuration shown in Figure 2 to simulate an HP SBC environment. To simulate typical HP SBC workloads, HP ran a series of performance tests based on the Heavy, Medium, and Light User scripts described in Table 3 . For each test scenario, HP began by running the appropriate script with a group of ten simulated users.
Tested environment Figure 2 illustrates the HP SBC test environment. Figure 2 : The tested environment Note: Test environments such as that shown in Figure 2 are available to customers at HP Solu tion Cen ters to help solve a wide variety of business problems.
Guidelines HP followed these guidelin es when configurin g servers for the test environment: • Memory Since all applications reside and are executed on the HP SBC server, memory resources on this server must be sufficient in order to opti mize system performance.
Configurations Table 4 summarizes the configuration s of systems used in the test envi ronment. Table 4 : System configurations Server Configuration HP SBC server Two-way HP ProLiant BL35p server blade with: • 2.4 GHz/1 MB AMD Optero n processors • 1 MB L2 cache • 4096 MB RAM • One 60.
System summary Table 5 summarizes the configuration o f the HP SBC server. Table 5 : HP SBC server configuration Component Description Operating system Microsoft Windows Server 2003, E nterprise Edition Version 5.
Performance test results HP tested a two-way HP ProLiant BL35p server blade with 2.4 GHz/1 MB Opteron processors to determine the optimal number of users supported in an HP SBC environment.
% Processor Time Figure 3 shows % Processor Time values for Heavy User s. Figure 3 : % Processor Time values for Heavy Users – showing an optimal level of 123 users Figure 3 indicates that an HP ProLiant BL35p se rver blade can support 123 Heavy Users befor e the % Processor Time value reaches 80%.
Canary time Figures 4 shows sample results for an HP ProLiant BL35p server blade running a typical canary script. Individual user response times are shown in blue , with a yellow line depicting average response times.
Results summary Figure 5 summarizes the optimal nu mbers of users supported by an HP ProLiant BL35p server blade (based on % Processor Time values). Figure 5 : Optimal numbers of users supported IMPORTANT: As with any laboratory benchm ark, the performance metrics quoted in this performance brief are idealized.
Appendix A – AMD Opteron processors The AMD Opteron processors deployed in the latest HP ProLiant serv ers help advance the future of industry-standard servers.
Benefits Table A-1 outlines key benefits of the Opteron processor. Table A-1 : Key benefits of the Opteron processor Feature Benefit Simultaneous 32- and 64-bit computing capabilities Users can run 32-bit and/or 64-bit applications and operating systems – without sacrificing performance.
Figure A-2 shows the approximate amount of dire ctly-addressable memory available with various Windows operating systems. Figure A-2 : Memory limits with Windows operating systems While 32-bit Windows.
Appendix B – SBC solution sizing As with any laboratory benchmark, the performanc e metrics quoted in this Performance Brief are idealized. In a production environment, these me trics may be impacte.
