    Thus, the clock speed can be increased. For example, the Pentium P54C processor in the IBM PC Server 720 operates at a clock speed of 100 MHz. The P54C is based on a fabrication process where transistors on the chip have a channel width of .6 microns (a .6 micron BiCMOS...

  • Page 17: External Interfaces

    A 90 MHz machine with a set of matched components can out perform a 100 MHz machine which is running with slow memory. IBM PC Servers are always optimized to incorporate these factors and they always deliver a balanced design.

  • Page 18: Multiprocessing

    It is the technology currently used by OS/2 SMP, Banyan Vines, SCO UNIX, Windows NT, and UnixWare 2.0. The IBM PC Server 320, 520, and 720 support SMP. The PC Server 320 and 520 support two-way SMP via an additional Pentium processor in a socket on the planar board.

  • Page 19: Caches

    Caches are cost-effective because they are relatively small as compared to the amount of main memory. There are several levels of cache implemented in IBM PC servers. The cache incorporated into the main system processor is known as Level 1 (L1) cache.

  • Page 20: Smp Shared Secondary Cache

    If two many processors are added, the system will even run slower due to memory bus bottlenecks caused by processor contention for access to system memory. The IBM PC server 320 supports SMP with a shared cache. Figure 1 shows SMP with shared secondary cache. ┌───────────────┐...

  • Page 21: Memory Interleaving

    E xclusive, S hared, or I nvalid. These refer to tags that are maintained for each line of cache, and indicate the state of each line. The implementation of MESI in the IBM PC server 720 supports two sets of tags for each cache line, which allows for faster cache operation than when only one set of tags is provided.

    (SIMMs) operating at the same speed (matched SIMMs). The PC server 720 uses a four-way interleaved memory with a word length of 64 bits. In this system, in order to interleave using 32-bit SIMMs, it is necessary to add memory in matched sets of eight SIMMs each.

  • Page 23: Synchrostream Technology

    It works much like a cache controller in that it pre-fetches extra data on each access to memory and buffers this data in anticipation of the next request. When the device requests the data, the IBM SynchroStream controller provides it quickly from the buffer and the device continues working. It does not have to wait for a normal memory access cycle.

  • Page 24: Memory Error Detection And Correction

    ECC Memory on SIMMs (EOS) Memory 1.4.1 Standard (Parity) Memory Parity memory is standard IBM memory with 32 bits of data space and 4 bits of parity information (one check bit/byte of data). The 4 bits of parity information are able to tell you an error has occurred but do not have enough information to locate which bit is in error.

  • Page 25: Error Correcting Code-Parity Memory (Ecc-P)

    ECC SIMMs. ECC SIMMs differ from standard memory SIMMs in that they have additional storage space to hold the check bits. The IBM PC Servers 500 and 720 have ECC circuitry and provide support for ECC memory SIMMs to give protection against memory errors.

  • Page 28: Isa Bus

    The Industry Standard Architecture (ISA) is not really an architecture at all but a defacto standard based on the original IBM PC/AT bus design. The main characteristics of the ISA bus include a 16-bit data bus and a 24-bit address bus.

    Figure 7. Micro Channel - Basic Data Transfer (20 MBps) However, in many cases, blocks transferred to and from memory are stored in sequential addresses, so repeatedly sending the address for each 4 bytes is unnecessary. With data streaming transfers, the initial address is sent, and then the blocks of data are sent;...

  • Page 30: Pci Bus

    Data streaming is useful for any adapters that perform block transfers across the Micro Channel such as the IBM SCSI-2 Fast/Wide Streaming RAID Adapter/A. MCA is implemented in some models of the IBM PC Server 300 and 500 lines and in all models of the PC Server 720.

  • Page 31: Disk Subsystem

    1.6 Disk Subsystem The disk subsystem is a critical element of server design. In this section we examine the controllers, the devices, and the interfaces between them. We will specifically address SCSI technology and also examine RAID technology in some detail.

  • Page 32: Scsi Technology

    The SCSI flexibility and high performance make it very suitable for the server environment. In fact, SCSI is the most widely used disk subsystem technology in advanced servers today. All the current IBM PC Servers except for a few at the low end use this technology. For these reasons, we will take a closer look at this interface.
  • Page 33 Tagged Command Queuing (TCQ) TCQ is a SCSI-II enhancement. It increases performance in DASD intensive server environments. With SCSI-I systems, only two commands could be sent to a fixed disk; the disk would store one while operating on the other.

  • Page 34: Scsi Adapters

    1.6.3 SCSI Adapters The SCSI adapter provides the interface between the host bus (for example Micro Channel or PCI) and the SCSI bus. The SCSI adapters that IBM has developed are: IBM Personal System/2 Micro Channel SCSI Adapter This adapter is a 16-bit Micro Channel bus master adapter adhering to the SCSI-I interface.

    In addition to the features supported with the IBM SCSI-2 F/W PCI Adapter, the IBM SCSI-2 F/W RAID adapter provides a RAID controller. Please reference 1.6.5, “RAID Technology” on page 22 for a discussion on RAID. 1.6.3.1 Summary The following tables summarize the features of the IBM SCSI adapters.

    Figure 13. RAID-1 (Disk Duplexing) 1.6.6.3 RAID-1 Enhanced - Data Strip Mirroring RAID level 1 supported by the IBM PC Server array models provides an enhanced feature for disk mirroring that stripes data and copies of the data across all the drives of the array. The first stripe is the data stripe; the second stripe is the mirror (copy) of the first data stripe, but, it is shifted over one drive.

  • Page 46: Recommendations

    Use IDE on smaller systems IDE actually outperforms SCSI on systems where only one or two devices are attached. Several models of the IBM PC Server 300 and 320 lines implement IDE as an integrated controller on the planar board. This is more than adequate if no more than a couple of hard disks will be used.

    This section discusses some technologies used in IBM PC Servers to comply with the United States Department of Defense (DoD) security requirements. Security features in the IBM PC Server line vary by model and all models do not have all the security features described here. Check the User s Handbook that is shipped with the system, to see what features your system contains.

    The cable cover also has a tamper-evident feature. 1.8.3 Passwords IBM PC Servers are equipped with several layers of password protection. The most basic is the power-on password. The power-on password must be entered correctly each time the system is turned on. After three incorrect attempts, the system must be turned off and back on in order to try again.

    1.9 Systems Management Systems management is an important element of a successful LAN. The IBM PC Server brand ships with a very powerful systems and network management tool called NetFinity. In this section, we look at the capabilities of NetFinity; first, we need to take a look at some of the underlying technology which NetFinity has incorporated.

  • Page 55 SNMP provides a means of communicating between the network management stations and the agents in the network resources. This information can be status information, counters, identifiers, etc. The SNMP manager continuously polls the agents for error and statistical data. The performance of the network will be dependent upon the setting of the polling interval.

  • Page 56: Netfinity

    This is called a trap. 1.9.3 NetFinity IBM NetFinity is a family of distributed applications designed to enhance the system monitoring and management capabilities of a network. NetFinity has a flexible, modular design that allows for a variety of system-specific configurations.
  • Page 57 NetFinity Services supports both IBM and non-IBM systems. It supports PCI, Micro-Channel, and EISA bus-based systems. It supports most client operating systems including DOS/Windows, Windows for Workgroups, OS/2 2.X, OS/2 Warp, OS/2 Warp Connect, and OS/2 SMP.

  • Page 58: Netfinity Manager

    It also supports Novell NetWare. This means that there is a version of NetFinity Services which installs as a NetWare NLM on the file server and allows the server to be managed by a NetFinity Manager station. NetFinity Services can also be installed on a Windows NT server and used to manage this platform as well.
  • Page 59 From this design, a manager may take control of the NetFinity client system to perform all NetFinity administrative and problem reconciliation tasks as if they were the local user s tasks. Additionally, IBM has been able to isolate NetFinity from any network, protocol or operating system layer dependencies.

  • Page 60: Systemview

    NetFinity implementation of DMI support provides instrumentation from its System Information Tool to the DMI service layer for both OS/2 and Windows clients. To accomplish this, IBM has delivered a DMI component agent that allows a NetFinity Manager to access a client desktop MIF database to deliver system specific information back into NetFinity DMI Browser.
  • Page 61 Problem: Detects, analyzes, corrects and tracks incidents and problems in system operations IBM provides programming interfaces to achieve a cohesive systems management architecture. An example of this is implemented in the NetView for OS/2 product.

  • Page 62: Fault Tolerance

    For example, a failure on the system planar board will often result in a server crash, and there is no way to anticipate it. Also software products running on the server present an ever increasing chance for server failure as well.

When a client needs to access a resource on the server, a request packet is sent over the network to the primary IOEngine. Clients always send their packets to the primary IOEngine because it advertises that it is the best route to the MSEngine.
  • Page 65 SFT III, to the MSEngine as well. When SFT III switches from the primary to the secondary server, clients may detect a slight pause, but server operations will continue because of SFT III s failure handling capabilities.
  • Page 66 Scenario 2. Hardware fails in the secondary server: The primary server notifies the system administrator that the secondary server is down and that it is still the primary server. SFT III keeps track of any disk changes following the secondary server s failure.

  • Page 67: Uninterruptible Power Supply (Ups)

    1.11 Uninterruptible Power Supply (UPS) Digital computers require a clean source of direct current (DC). It is the computer s power supply which takes an alternating current (AC) from the input line and transforms it into clean DC voltages. However, problems on the input AC signal can often lead to DC voltages that are less than satisfactory for the digital circuits to operate properly.

  • Page 68: Apc Powerchute

    While a UPS can enable the server to continue operating even if there is a power loss, the primary benefit of a UPS is that the server software has time to ensure that all caches are written to disk, and to perform a tidy shutdown of the system.

  • Page 181: File Server Performance - General Characteristics

    Figure 140 shows a graph of file server performance where throughput initially increases at a constant rate as users are added to the server. As the total number of users is increased, the network operating system is able to maintain a sufficiently high disk cache hit rate.
  • Page 182 LAN adapter is able to transfer data. The peak of the curve is the maximum server transaction rate that the particular server configuration is capable of sustaining for a specific transaction type. The maximum transaction rate is primarily dependent upon performance of the network adapter and disk subsystem combination.

  • Page 183: Differences In Lan Adapters

    Since most disk subsystems are significantly slower than a cache-hit operation, the throughput curve begins to decline. High performance disk subsystems, such as an IBM RAID Controller with Fast SCSI-2 drives, offer such a high level of performance that for many applications it allows the peak transaction rate to be sustained indefinitely.

    The efficiency at which access is performed is directly related to the file server performance. The following section describes some of the findings of the IBM PC Server performance laboratory on the major factors that affect hard disk subsystem performance.

  • Page 189: Default Block Sizes Based On Volume Size

    500 to 2000MB 2000MB and up Recommendation: IBM recommends a 64KB block size for all NetWare 4.1 volumes. The larger 64KB allocation unit allows NetWare to use the disk channel more efficiently by reading and writing more data at once. This results in faster access to mass storage devices and improved response times for network users.
  • Page 190 A directory entry stays in a cache buffer as long as it s being accessed frequently. The server will allocate a minimum number of directory cache buffers at boot time and then increase this value automatically as the demand grows for more buffers.

  • Page 191: Memory Requirements

    Let us illustrate with an example. Let s say that the number of original cache buffers allocated at server startup was 3000. Let us also say that the value of the total cache buffers is 2500 after the file server is up and running and quiesced.
  • Page 192 Recommendation: Novell recommends that you maintain the total number of cache buffers at 70% of the total server memory. If you regularly monitor this parameter and notice that it is lower than 70%, then it is time to think about adding more memory.
  • Page 193 As discussed previously in 1.6, “Disk Subsystem” on page 16, some models of the IBM PC Server line provide RAID support. This is the recommended way to gain this same kind of performance while ensuring an added level of fault tolerance.

This value is normally determined by the device driver and normally defaults to On all IBM disk controllers, this read-after-write operation is completed at the hardware level. Leaving this parameter ON will degrade disk subsystem performance.

    3. For Ethernet 10 Mbps = 1514 packet size In the case of 4 Mbps token-ring adapters, a packet size of 4202 can be supported on some of the newer IBM LAN adapters. Note If you are in a multi-segment LAN or WAN environment, you must make sure that all inter-networking devices (bridges and routers for example) are capable of passing the packet size that you choose.
  • Page 196 LAN activity. Note The IBM LANStreamer MC32 requires minimum packet receive buffers set to 200 or above. It may need to be higher depending on the number of LAN users.

  • Page 197: System Memory

    The way in which NetWare manages system memory has a direct bearing on file server performance. Because of this, it is important to have an understanding of how the server allocates memory and the use of set parameters to control the system memory.
  • Page 198 MONITOR.NLM utility can help you determine the effect of changing the number and size of the buffers. It may be necessary to add more memory to the server if the performance tuning results in the depletion of the total cache buffer memory available to efficiently service file requests.

    3. Allocate memory for FAT and directory caching. To calculate this requirement, multiply the amount of your server s hard disk space (in MB) by 0.008. For example, if you have a total of 1 GB of disk space, multiply 1 GB by 0.008.
  • Page 200 LAN load and use the system processor more efficiently. The use of bus mastering LAN adapters and disk controllers also helps to spread the load on the file server more evenly and thereby uses the system processor in a more efficient manner.
