Summary of Contents for Compaq 108164-003 - ProLiant - 800

  • Page 1 Compaq Computer Corporation This Compaq White Paper provides the results of a performance analysis conducted by Novell and Compaq engineers on the GroupWise Server for Novell IntranetWare. The information here is based on technical knowledge acquired by both Novell and Compaq O N T E N T S engineers while testing these products in a closely controlled environment.
  • Page 2 This test is not a determination of product quality or correctness, nor does it ensure compliance with any federal, state or local requirements. Compaq does not warrant products other than its own strictly as stated in Compaq product warranties.
  • Page 3 Investment. B J E C T I V E One objective of this Compaq White Paper is to provide information to assist current customers running Novell GroupWise R5.2 for IntranetWare on Compaq servers in optimally configuring their server(s) to achieve the highest possible performance from their hardware and software.

  • Page 5 HITE APER (cont.) Everything You Need In One Place The workplace is hectic enough without constantly having to search for E-mail, Web addresses, faxes, voice-mail, documents, appointments, and to-do lists. GroupWise allows you to gather all that information in one place, with a simple interface that’s as easy to manage as E-mail. It’s called the Universal Mailbox, and it even lets users store Web addresses that link directly to the referenced home page.
  • Page 6 HITE APER (cont.) GroupWise Is In Good Company With more than 7 million users, GroupWise is one of the most popular messaging solutions of its kind. If shared messaging and collaboration are hallmarks of your company, you need the reliable, powerful communications solution GroupWise provides. R O U P I S E Y S T E M...
  • Page 7: Performance Characteristics

    CPU, memory, and disk subsystem. Data gathered from Novell NetBench testing is presented and configuration recommendations are provided based upon data analysis and the experience of Novell and Compaq engineers. Performance Characteristics Performance can be viewed in one of two ways. To a system administrator, performance means effective management of system resources.
  • Page 8: Test Configuration

    The Post Office agent was configured using default settings, with the following exceptions: The TCPTHREAD count was set to 30 The MFTHREAD count was set to 12 Hardware and Software Configuration Hardware System: Compaq ProLiant 5000 Compaq ProLiant 800 CPU: 200 MHz Pentium Pro (1-4) Memory: 128MB –...
  • Page 9: Test Procedure

    This section offers guidelines for obtaining optimal value and performance from your Compaq server. These guidelines are based on tests designed by Novell and Compaq engineers. The tests are based on the analysis of the data gathered from NetBench testing. A description of each of the subsystems, the data collected from testing, and recommendations for the configuration of your Compaq server are included in this section.
  • Page 10 In the testing performed by the Novell and Compaq team, the performance of the Pentium processors was compared to that of the Pentium Pro processors. The type of processor and its associated architecture features have as much impact on performance as processor-rated clock speed.
  • Page 11 HITE APER (cont.) Memory Memory is one of the most valuable resources in a Novell NetWare server. Memory is used for both disk cache as well as program execution. The detail memory requirement for NetWare 4.1 server can be found in Novell Application Notes, January 1995. In that calculation, the administrator needs to take a number of variables into consideration such as Total Disk Capacity, Total Number of Clients, Volume Block size, and so on.
  • Page 12 Depending on the type of files stored on the volume, or the application you used, you can increase or decrease the volume block size to improve the performance. The Novell/Compaq test team found that setting the volume block size to 64 KB yields the best result. The following graph shows the performance comparison.
  • Page 13 HITE APER (cont.) Performance Comparison of Volume Block Size 2500 2000 1500 1000 16KB 64KB Volume Block Size Figure 3. Volume Block Size Performance Comparison The test results show that there is a measurable difference in response time rates between various volume-block sizes.
  • Page 14 With Compaq Smart-2 controller technology, this reconstruction process allows the failed drive to be replaced while the system continues to operate at a slightly reduced performance.
  • Page 15 Fault Tolerance Figure 4. Fault tolerance performance comparison Novell/Compaq test results show a measurable difference in response time rates between RAID 1, RAID 5 and RAID 0. RAID 0 achieved the best performance, outperforming RAID 5 by 10-20% in response. Keep in mind that while RAID 0 utilizes available disk space most efficiently, this level offers no fault tolerance protection.
  • Page 16: Networking Subsystem

    (cont.) The 75% Read / 25% Write ratio, yielding the best response time in our test, is recommended by Novell and Compaq engineers. This improvement in performance can be explained by the additional read-related work the test script performs. Performance Comparison of Controller...
  • Page 17 HITE APER (cont.) Physical segmentation To physically segment a network, you must first add more NICs to the server and then balance the network load among the multiple NICs. Segmenting a network by adding additional NICs and hubs has the added benefit of creating separate collision domains. Creating additional collision domains minimizes packet collisions by decreasing the number of workstations on the same physical network.
  • Page 18 To compare and evaluate 10-Mb/s Ethernet and 100-Mb/s Ethernet, parallel test environments were set up in the integration testing labs at Compaq. The results, shown in Table 3, compare a 10-Mb/s Ethernet LAN with that of a 100-Mb/s Ethernet LAN. IntranetWare Performance Monitor indicates the total throughput for the NetFlex-3/P controller installed in the server.
  • Page 19 U N I N G Bus System Tuning Compaq introduced dual peer PCI buses with the ProLiant 5000 for added performance and reliability. For performance, both buses are independent, allowing a full 267 MB/s of I/O. For added reliability, the ProLiant 5000 offers support for redundant 10/100 TX PCI UTP Network Interface Controllers (NICs) as well as redundant disk controllers.
  • Page 20 HITE APER (cont.) In order to avoid I/O contention, the following Server Configuration of ProLiant 5000 is recommended. Table 4. Server Configuration of ProLiant 5000 One network controller and one array controller Device Slot 10/100 TX PCI UTP Secondary SMART-2/P Array Primary One network controller and two array controllers Device...
  • Page 21 A GroupWise Server tunable parameter that impacts the system performance is the Read Ahead Cache which is the amount of memory allocated to the GroupWise Server specified in bytes. Novell and Compaq engineers recommend using the default read-ahead cache due to the 15-20% performance gain show in the following figure.
  • Page 22: System Processor

    GroupWise Server. The conclusion is that the faster the processor, the better the performance gains for the system. Therefore, Novell and Compaq engineers recommend the fastest processor that can be purchased within the budgetary limitations of your project.
  • Page 23 Preliminary tests show that a ProLiant 800 can successfully sustain 500 users and a ProLiant 5000 can sustain 1000 users. These tests prove that Compaq is a viable solution for GroupWise needs. More detailed information will be forthcoming after extensive testing at Novell's SuperLab facility in Provo, Utah.
