PC Server -- New Options
The PC ServeRAID SCSI Adapter (#1930, 70G8489) is a very high-performance, three-channel, PCI RAID adapter. This technologically advanced, RAID adapter supports up to 45 SCSI-2 fast/wide hard drives to satisfy mission-critical applications that require protection for large amounts of data. In addition, this state-of-the-art RAID adapter is designed to support Ultra SCSI hard drives, the next generation of drive technology just becoming available in the industry. When installed in PC Server 520 and 720 systems, this single adapter can support RAID levels 0, 1, and 5 disk arrays in all 18 hot-swap drive bays.
PC ServeRAID SCSI Adapter achieves outstanding performance through the use of a RISC processor, 4MB of cache, and a dual bus architecture with a local PCI bus. These attributes significantly improve system performance by reducing traffic on the system local bus and by rapidly processing complex RAID algorithms with the high-speed processor.
IBM incorporates Logical Drive Migration with the PC ServeRAID SCSI Adapter. This new technology allows changes to be made to the RAID configuration while the PC Server is up and running. Using online utilities, new RAID arrays can be added and RAID levels can be modified without deleting the original array or requiring the data to be restored from a backup source. In addition, the PC ServeRAID SCSI Adapter stores critical RAID configuration information in multiple locations on the adapter and hard disk, making disaster recovery or migrating hard drives from one server to another quick and easy. This means hard drives can now be removed from your server and installed in another server or IBM PC Server expansion tower -- in any order. The PC ServeRAID SCSI Adapter takes care of getting the configurations from the hard drives and remapping them as necessary.
This adapter contains three internal connectors, one for each channel and one external connector. Three of the four connectors can be used for attachment of SCSI devices. The PC ServeRAID SCSI Adapter can support multiple external SCSI devices through the use of new Internal Bulkhead Cable options. Installation publications, a DASD status cable, device drivers, and RAID utilities are included. The PC ServeRAID SCSI Adapter supports popular network operating systems such as OS/2(R), Windows+ NT, NetWare, and SCO. This adapter is supported in all PC Server 320, 520, and 720 models. In addition, the PC ServeRAID SCSI Adapter supports external enclosures such as the PC Server Enterprise Expansion Tower and the 3517 SCSI Multi-Storage Enclosure.
The Internal Bulkhead Cable (#2406, 76H2675) option is a single, 16-bit SCSI cable with bracket and screws that converts a PC ServeRAID SCSI Adapter internal connector to an external port for attachment of SCSI-2 fast/wide devices through the use of a Fast/Wide to Fast/Wide External SCSI Cable (70G9857). This option is designed to allow connection of external SCSI devices to either one or two of the internal connectors on the adapter installed in PC Server 320, 520, or 720 systems. The cable connects to an internal connector of the PC ServeRAID SCSI Adapter and can be routed to the PC Server rear panel cutouts. Customers should verify their PC Server model has a cutout available before ordering this option. A bulkhead cable option must be ordered for each connector-to-cutout installation.
The PC Server HS Backplane III (#2405, 76H2670) is a new backplane designed for the PC Server 520, which supersedes the PC Server HS Backplane III (#2302, 70G9855). This new backplane option must be used with these servers when additional backplanes are required for expansion.
The PC Server SMP 166MHz Upgrade (#2362, 94G6053) is a 166MHz Pentium microprocessor designed to be easily installed in the second ZIF socket of PC Server 320 and 520 models with standard 166MHz uni-microprocessors to support SMP operations. This option comes with installation instructions and a special heat sink designed for optimum reliability for IBM PC Server installations.
High-Performance Processor Subsystem
PC Server 520 systems are high-performance, enterprise, LAN-server solutions. All models incorporate powerful 166MHz or 133MHz Pentium processors with SMP upgrade capability, 512KB L2 write-back cache, and 64MB or 32MB of ECC-on-SIMM system memory.
- The Pentium microprocessors handle internal operations at 166MHz
or 133MHz clock speed, dependent on model, while external I/O bus
transactions run at 66MHz.
- 16KB internal cache is standard, 8KB is used for data and 8KB is
used for instructions.
- High-performance 512KB L2 write-back cache uses 15 ns memory.
- The system board contains a second microprocessor ZIF socket that
supports a second Pentium microprocessor for SMP operations.
- Two 32MB or two 16MB, high-speed, ECC, 70 ns memory SIMMs are standard, with total system memory expandable to 256MB.
PC Server 520 is a maxi-tower mechanical package designed for efficient cooling, system security, and exceptional data storage scalability.
- Twenty-two device bays are available for internal data storage of
over 49GB. Large-capacity configurations can be achieved inside
this mechanical package that supports up to 18 one-inch, hot-swap
hard drives, plus a 4X CD-ROM, 1.44MB floppy diskette drive, and a
full-high 5.25-inch bay for an optional 24/48GB internal tape
- PC Server 520 PCI/EISA models contain nine physical adapter slots,
three PCI and six EISA, with one slot being shared. This allows
configurations of either three PCI adapters and five EISA adapters
or two PCI adapters and six EISA adapters (an IBM PC Server SCSI-2
Fast/Wide PCI Adapter or PC ServeRAID SCSI Adapter and ISA SVGA
video adapter consume two slots, the Ethernet Quad PeerMaster PCI
Server Adapter consumes another slot on LAN-ready models).
- The PC Server 520 PCI/Micro Channel model contains eight adapter
slots, two are PCI and six are Micro Channel (the PC ServeRAID
SCSI Adapter takes one PCI slot).
- Array models, which include the PC ServeRAID SCSI Adapter, support
up to 45 fast/wide, hot-swap hard disks for RAID 0, 1, and 5
operations. Non-array models contain either an integrated SCSI-2
fast/wide controller or adapter that can support up to 15 SCSI-2
- A standard 434-watt power supply provides power to support entry system configurations, while a 220-watt modular power supply option is available for more robust hot-swap hard drive expansion into the two optional lower hot-swap drive banks. In addition, the PC Server 780W Redundant Power Option is offered to support mission-critical applications, dependent on server availability.
High-Performance Disk Subsystems
PC Server 520 array models feature the PC ServeRAID SCSI Adapter designed specifically for disk fault tolerance for mission-critical LAN environments. Non-array, PCI/EISA models contain an IBM PC Server SCSI-2 Fast/Wide PCI Adapter, while the PCI/Micro Channel model contains this same function on the planar.
- PC ServeRAID SCSI Adapter is a very high-performance,
three-channel, PCI RAID adapter that supports up to 15 hard drives
per channel with RAID levels 0, 1, and 5. It features an onboard
RISC microprocessor to handle the complex RAID algorithms with
blazing speed. It also contains a high-speed 4MB cache and a
local PCI bus to further enhance performance. This adapter
includes utilities for setup, display, and administration of disk
arrays for NetWare 3.x and 4.x, OS/2, Windows NT, and SCO.
- High-speed hard drive options provide extremely fast LAN server
performance for PC Server 520 systems. These drives are available
in fast/wide versions of 1.12GB, 2.25GB, or 4.51GB. With average
seek times of 8.0 ms, these high-speed drives spin at 7200 rpm to
provide state-of-the-art server performance.
- When used with TME 10 NetFinity, IBM's high-speed drives provide Predictive Failure Analysis(TM) (PFA), which alerts the system administrator of an impending drive failure 24 to 48 hours before it happens. This feature allows data to be backed up and drives to be replaced with minimal disruption to business. For hard drives with this PFA feature covered by IBM warranty, IBM will replace the drive if the NetFinity PFA service detects a failure.
Systems Management: All PC Server 520 systems feature TME 10 NetFinity, a comprehensive systems and asset management software tool using a graphical interface, which is contained on CD for installation convenience. NetFinity allows the LAN administrator to monitor and manage NetWare, Windows NT, and OS/2 LAN servers from either OS/2, Windows 3.1, or Windows 95 workstations.
- This systems management software collects detailed hardware
configuration information, such as model and processor, adapters
installed on the PCI, EISA, or Micro Channel bus, and RAID
- Alert pager support allows managing systems with a modem to dial
out to a pager when an alert is received. This ensures the LAN
administrator can be informed of alerts as they occur.
- An event scheduler service is included that can automatically
start NetFinity services on one or more systems.
- PFA alerts the system administrator of an impending hard drive failure, normally 24 to 48 hours before it occurs.
The remote server management provided by NetFinity greatly improves the LAN administrator's productivity and remote LAN management capability. This saves money and time and contributes to lower network operating costs, less travel to remote sites, reduced downtime, and much better overall control through active monitoring, fault prevention, and faster problem resolution.

The PC Server 520 system is an enterprise LAN server that combines industry standard technologies, very large data storage capacity, rugged dependability, ease of installation, and system management, plus excellent performance through its 166MHz or 133MHz Pentium SMP capability. Now these systems also contain Lotus Notes Version 4.1 Server, Single Processor Edition at no additional charge. This powerful combination of features provides a server of exceptional value and function. The new systems are available as array and non-array configurations. The array models are designed to meet the complex requirements of medium to large businesses requiring higher levels of server availability and fault tolerance for data storage. The non-array models are ideal in the same environments where fault tolerance of data through hardware-implemented RAID is not a requirement.
These new servers are positioned above the current PC Server 520 systems because of their higher microprocessor and RAID adapter performance. They are ideal solutions for complex and advanced interconnected LANs found in large and medium businesses running critical and noncritical business applications. The PC Server 520 array models using RAID 1 or 5, standard ECC-on-SIMM memory, large hot-swap data storage capacities, and an optionally available PC Server 780W Redundant Power Option offer a very cost-effective solution for mission-critical business environments.

This BIOS provides the hardware instructions and interfaces designed to support the standard features of the PC Server 520 and to maintain compatibility with many software programs currently operating under PC DOS and OS/2 on PC Servers. However, due to the higher speed of the processors in these models, some timing-sensitive software may require modification.
Detailed information relative to IBM and non-IBM devices, adapters, software, and network operating systems supported with PC Servers can be accessed via the World Wide Web at URL:
- PC Server 520 supports 32MB and 64MB ECC-on-SIMM memory kits.
These kits contain two matched memory SIMMs, because all memory
SIMMs must be of the same type and be installed in matched pairs.
Refer to the Compatibility section of the Sales Manual or contact
your IBM reseller or IBM representative for specific information
on supported memory SIMMs.
- High-performance BIOS on PC Server 520 PCI/EISA models uses 128KB
of system memory; an additional 256KB is reserved for installing
options that may require additional memory for BIOS shadowing. PC
Server 520 PCI/Micro Channel models use 160KB of system memory; an
additional 96KB is reserved for installing options that may
require additional memory for BIOS shadowing.
- PC Server 520 PCI/EISA models support full-length adapters in EISA
slots one, two, and three, and PCI slots zero and one. The
remaining EISA and PCI slots support half-length adapters.
- PC Server 520 Micro Channel model supports a maximum of two Type 5
Micro Channel adapters per system. The IBM Ethernet Quad
PeerMaster Server Adapter is a Type 5 adapter.
- Because these systems are designed as industry standard servers
using an industry standard diskette drive interface, the location
of the media eject button on the industry standard diskette drive
and the lack of support for a electronic eject 2.88MB diskette
drive option may be a limitation for customers with certain
- PC Server 520 systems using the SCSI-2 Fast/Wide PCI Adapter or
containing integrated SCSI controller have three SCSI-2
connectors. Two connectors are internal, one fast and one
fast/wide. The third external connector is fast/wide. Systems
containing an adapter allow for any two of these ports, in any
combination, to be used for SCSI device attachment. Systems with
an integrated SCSI controller allow for either of the internal
connectors to be used but not both at the same time; however, the
external connector can always be utilized.
- PC Server 520 models can support a maximum of two PC ServeRAID
SCSI Adapters per system unit.
- While the PC ServeRAID SCSI Adapter can support up to 15 drives
per channel, actual configurations in PC Server 520 and 720
systems are limited to 12 SCSI-2 fast/wide hard drives per channel
for internal storage. External storage is limited in today's SCSI
environment to six SCSI-2 fast/wide drives per channel because of
SCSI cable length restrictions associated with storage in PC
Server Enterprise Expansion Tower.
- Microprocessor SMP upgrades must be of the same clock speed.
Mixing microprocessors of different speeds is not supported.
- Customers should use the version of ServerGuide that ships with the system, or a later version, to load software and drivers. Earlier versions of ServerGuide may not be compatible with the server.
ServerGuide Ordering and Installation Information
ServerGuide is available when shipped as part of the PC Server 520 and is not sold separately.
ServerGuide CDs contain encrypted software products. When you receive your IBM PC Server you must order activation keys, at a charge, to unlock and install the software products you want to use.
Each ServerGuide package contains a unique ServerGuide license number, which must be specified on your software order with the software product part number. The ServerGuide license number and the part number are used by IBM to generate the activation key, which is then provided to the customer. The activation key can then be used to unlock the software product for installation.
A product order form is included in ServerGuide documentation delivered with the IBM PC Server. Activation keys are normally communicated by IBM within a few hours, assuming communication by fax.
For complete information about ServerGuide, including ordering part numbers, refer to Software Announcement 296-057, dated February 27, 1996.
Proof of Entitlement for ServerGuide Software Products: When an order for one of these products is processed, a fax containing the activation key and product identification is sent by IBM to the remarketer who placed the order. The remarketer in turn sends a copy of the fax to the customer. Proof of Entitlement to use one copy of the software product consists of a copy of the IBM fax containing the activation key and a copy of the ServerGuide license diskette label showing the diskette serial number.
The customer should attach a copy of the IBM fax to the copy of the diskette label and keep as Proof of Entitlement.
For IBM customers ordering through IBM representatives, the same Proof of Entitlement applies. In this case, the fax containing the activation key will normally be transmitted directly from IBM to the customer.
Customer Responsibilities: The PC Server 520 is designated as customer setup. Customer setup instructions are shipped with the system.
Basic Configuration: PC Server 520 array systems contain a fast/wide cable connected to the SCSI-2 controller/adapter at one end; the other end is connected to the input side of the hot-swap backplane. A two-drop fast/wide cable is connected to the output side of the hot-swap backplane. The first drop is connected to the CD-ROM through a 68- to 50-pin SCSI converter, while the second drop is provided for attachment of an optional internal SCSI device in either bays B1 or B2. If connecting an 8-bit (narrow) device to this cable, a 68- to 50-pin SCSI converter (32G3925) must be obtained. The remaining B1 or B2 bay supports a floppy disk drive interfaced device.
Internal Hot-Swap Expansion Considerations for Non-Array Models: When adding second or third banks of hot-swap hard disk drives, it is necessary to install the PC Server Power Supply Upgrade (70G9739) in addition to the PC Server Hot-Swap Backplane III (76H2670) and SCSI PCI Card to Backplane Fast/Wide Cable (94G3988) options. Also, an appropriate SCSI adapter, such as the PC Server SCSI-2 Fast/Wide PCI Adapter II (94G4673), is required for attachment of the backplane.
Internal Hot-Swap Expansion Considerations for Array Models: Array models support up to 12 SCSI-2 hot-swap hard drives per channel. When adding a second hot-swap backplane, a PC Server Power Supply Upgrade (70G9739) is required in addition to the PC Server Hot-Swap Backplane III (76H2670) and SCSI PCI Card to Backplane Fast/Wide Cable (94G3988). One end of the SCSI-2 PCI Card to Backplane Fast/Wide Cable is connected to one of the remaining two internal connectors on the PC ServeRAID SCSI Adapter, while the other end is connected to the hot-swap backplane. If installing a third PC Server Hot-Swap Backplane III, a Backplane-to-Backplane Cable (94G4070) can be used to daisy chain from the second backplane. This eliminates the need to use a second SCSI PCI Card to Backplane Fast/Wide Cable. However, for performance considerations, the third backplane can be cabled directly to the PC ServeRAID SCSI Adapter through the use of SCSI PCI Card to Backplane Fast/Wide Cable. Daisy chaining more than two backplanes per connector/RAID channel is not supported.
Cable Orders: Except for system power, keyboard, mouse, and monitor connections, there are no cabling requirements to set up and test this server. Cables are provided with the system unit and monitor, and the instructions are provided as part of initial setup.
Appropriate cabling is necessary to attach the server to the LAN. The cabling is dependent on the network interface card (NIC) and LAN requirements chosen. Cabling selection, installation, and physical connection are customer responsibilities.
Installability: The PC Server 520 models require at least 30 minutes for installation. Installation includes unpacking, setting up, and powering on the system. Additional time is required to install an operating system and other adapters or features.

Security, Auditability, and Control
Security and auditability features of these servers are:
- Power-on and supervisor passwords functions provide controls of
who has access to the server setup program and data on the server.
- A mechanical lock allows users to lock the system front-cover door
to prevent unauthorized personnel access to diskette drives or
- Selectable boot sequence can be used to prevent unauthorized
installation of software or removal of data from the diskette
- Tie-down capability is achievable by utilizing a common "U" bolt
attached to the back frame.
- Operation without a keyboard and display are supported once the
server is configured with the appropriate network operating
system. This minimizes the risk of unauthorized persons tampering
with the system software and configuration.
- A PC Server security cover is optionally available to prevent
unauthorized access to server external ports and cover retaining
- The PC Server 520 PCI/Micro Channel model is C2 security-enabled. This security system is designed to alert the system administrator if unauthorized intrusions to the PC Server 520 are detected.
PC Server 520 systems with these adapters also conform with ANSI SCSI-2 and work with SCSI-2 fast or fast/wide devices. Customers are responsibile for ensuring that the server is secure, or has a security cover, to prevent sensitive data from being removed via the external SCSI ports. User management is responsible for evaluation, selection, and implementation of security features, administrative procedures, and appropriate controls in application systems and communications facilities.
