  • Page 2: Executive Summary

    The HP ProLiant DL585 G5 is a highly manageable, rack-optimized, four-socket maximum performance in an industry-standard architecture. With up to four Quad-Core AMD Opteron™ processors and a large memory footprint, the HP ProLiant DL585 G5 server delivers the performance and performance-per-watt needed for compute-hungry database, virtualization, and consolidation applications.

  • Page 3: Introduction

    Introduction The HP ProLiant DL585 G5 server (shown in Figure 1) is ideal for multi-threaded, multi-tasked environments, high-performance computing, and HP SBC. Figure 1. HP ProLiant DL585 G5 server AMD Opteron processors The HP ProLiant DL585 G5 server supports up to four Quad-Core AMD Opteron 8300 Series processors.

  • Page 4: Amd Dual Dynamic Power Management

    This section describes how HP determined the optimal number of users supported by a 4P HP ProLiant DL585 G5 server equipped with the Quad-Core AMD Opteron Processor Model 8360 HE GHz) – henceforth referred to as the HP ProLiant DL585 G5 server – in a 64-bit test harness. Important: As with any laboratory testing, the performance metrics quoted in this paper are idealized.

    This section provides more information on test tools, user profiles and test scenarios. Test tools To facilitate the placement and management of simulated loads on an HP SBC server, HP used Terminal Services Scalability Planning Tools (TSScaling), a suite of tools developed by Microsoft to help organizations with Microsoft Windows®...

  • Page 6: User Profiles

    User profiles To simulate typical workloads in this environment, HP used scripts based on the Heavy, Medium, and Light User profiles described in Table 2. Table 2. User profiles incorporated into the test scripts User class Activities Heavy User Heavy Users (also known as Structured Task Workers) tend to open multiple applications simultaneously and remain active for long periods.

  • Page 7: Test Scenarios

    Test scenarios For the Heavy User type, HP initiated testing by running the appropriate script with a group of 15 simulated users. Start times were staggered to eliminate authentication overhead. After these sessions finished, HP added 15 more users, then repeated the testing. Further groups of 15 users were added until the maximum number of users was reached.

  • Page 13: Canary Times

    Canary times Figure 4 shows sample results for the HP ProLiant DL585 G5 server running a typical canary script. Individual user response times are shown in blue, with a yellow line depicting average response times. HP analyzed this figure to determine when response times began to increase markedly and consistently over a baseline level, indicating that user response times had become unacceptable.

  • Page 14: Test Analysis Summary

    • Utilize battery-backed write cache (see • Since built-in storage is often insufficient to support a large number of users in an HP SBC environment, consider deploying additional RAID arrays/SAN support. Note also that when a SCSI RAID array is used to host user profiles and page files, the number of spindles deployed has a significant impact on the response times associated with file access.

    Write cache is of particular interest in the HP SBC environment. After buffering all the data associated with a particular write command, the Smart Array controller indicates to the HP SBC server that the data transfer to the disk is complete –...
