Systems/Options
Important note before you begin
Systems may be configured with more than 16 CPUs per partition, only when used with Tru64 UNIX V5.1 or OpenVMS V7.2-1H1 with Update #5. System
components, such as master PCI drawers and numbers of PCI options supported must be consistent with this requirement.
Step 1 −
−−
− Assess Application Requirements
• Selection of system components must be made in the context of total application requirements. Although the configuration of system components must
be done in steps (for example, base system, CPUs, memories, etc.), these steps cannot be done in isolation.
• The order in which requirements are assessed is also important, since one requirement may impact others. Before proceeding, it would be useful to
assess the total application requirements in the following order:
• What level of availability is required?
- If no single points of failure are allowed, then the solution should be configured as a cluster.
- If access to specific devices must be assured, consider redundant adapters, RAID, N+1 power, redundant PCI drawers, and redundant consoles.
- If software redundancy is required, consider clusters and/or hardware partitioning. The choice of hardware partitioning will generate a need for
multiple master PCI drawers, multiple consoles, and I/O adapters.
- If the “CPU On-Line Add and Remove” feature is required, refer to document EK-GSHPG-RM for configuration and operational requirements.
• What level of hardware partitioning is required for optimal system management?
• What overall capacities are required in terms of processor performance, memory capacity, and disk storage?
- If the configuration will contain more than 16 CPUs, hardware partitioning is required.
• How should the system be configured to optimize performance?
- In most cases, optimum performance is achieved if the system resources (CPUs, memory and I/O adapters) are balanced across the quad building
blocks in the system.
- Memory should be configured according to application guidelines listed in Step 4.
• What are the near-term system expansion needs?
• How will system cabinets be physically arranged? This will determine if expansion cabinets are required and what cable lengths are required.
Note: Most configuration steps require that these data be considered in whole or in part. Be sure to execute each step in the context of the total
application requirements.
System Ordering Requirements:
Certain system components or services are either required for normal operation or are recommended for best system performance and/or operation. This
document uses the following definitions to specify these options:
• Mandatory purchase: The system cannot function without this option or service − the option or service must be ordered with the system.
• Required to function: This option or service is needed to support a working system − the option or service must be ordered with the system or be
available onsite.
• Recommended: System performance or function will be enhanced if this option or service is ordered.

Systems/Options
Step 2 −

− Select base system
AlphaServer GS320 systems require selection of the following items:
Mandatory Purchases:
• Base system with operating system license (either OpenVMS or Tru64 UNIX) and one 731-MHz CPU module
• Minimum of one memory module
Required Options and Services:
• Software media and documentation for first system onsite
• Installation and/or startup services
• System management console or device and software with equivalent functionality
Recommended Services:
• CarePaq Priority Service Plan
• VIS Services
Note: The base system should be selected in the context of the number of hardware partitions required, the total capacity required, and the anticipated
near-term system growth.

Options
Step 3 −

− Additional SMP CPUs
• AlphaServer GS320 base systems contain one CPU module. Additional SMP CPUs may be added, up to the limits shown in above
table. SMP CPU options include an operating system SMP license.

Compaq Capacity on Demand (CcoD) CPUs
• AlphaServer GS320 base systems can be configured with optional Compaq Capacity on Demand (CCoD) CPUs for non-disruptive
future capacity expansion. The CPUs will be field installed as part of the system installation. The total number of CPUs – base CPU,
SMP CPUs, and CCoD CPUs – must adhere to the limits shown in the above table. Refer to the Compaq Capacity on Demand
Program described in the “Upgrades” section.
GS160/320 CCoD SMP CPU, includes one 6/731-MHz CPU module with 4-MB on-board
cache, Tru64 UNIX SMP license, and CCoD program license

Step 4 −

− Select Memory Options
• Memory options are engineered specifically for use with this series and include additional required components that are integral to the
system architecture.
• Memory options consist of a series of base modules that contain one memory array. A second array (called "upgrades" in the table)
may be added to a base module in the factory or in the field.
0.5-GB GS80/160/320 base memory module
3X-MS8AA-AB
0.5-GB GS80/160/320 memory DIMM upgrade
3X-MS8AA-AU
1-GB GS80/160/320 base memory module
3X-MS8AA-BB
1-GB GS80/160/320 memory DIMM upgrade
3X-MS8AA-BU
2-GB GS80/160/320 base memory module
3X-MS8AA-CB
2-GB GS80/160/320 memory DIMM upgrade
3X-MS8AA-CU
4-GB GS80/160/320 base memory module
3X-MS8AA-DB
4-GB GS80/160/320 memory DIMM upgrade
3X-MS8AA-DU
Note: ES40 configurations that require N+1 redundant power are restricted to a maximum
of 24-GB of mixed memory (sixteen 1-GB DIMMs and sixteen 512-MB DIMMs). If
N+1 redundant power is not required, 32-GB of memory is supported.
Memory Configuration Guidelines
Memory options should be selected in the context of the application's sensitivity to memory bandwidth and memory capacity, and the number of hardware
partitions. This will determine the number of memory base modules and upgrades needed. The total capacity required will determine the size of the arrays
to be chosen.
The configuration of memory may influence the performance of applications, and there are numerous ways to configure the choices of memory base
modules and upgrade DIMMs. The following general guidelines can lead to several configuration choices. Application-specific guidelines will help narrow
down the choices.
• Configuring for capacity: The highest capacity is achieved when the 3X-MS8AA-DB/DU combination is used.
• Configuring for performance: Interleaved operations reduce the average latency and increase the memory throughput over non-interleaved operations.
Each memory base module is capable of 4-way interleaving with one array (no upgrades added) or 8-way interleaving with two arrays (base module
plus one upgrade). A QBB configured with eight arrays (four base modules plus four array upgrades) provides 32-way interleaving and has the
maximum potential memory bandwidth. Refer to “Memory Applications Examples” below to determine which applications gain the most benefit from
this bandwidth.
• Memory modules should be configured in powers of 2: that is, 0, 1, 2, or 4 base modules in a QBB. Upgrades should also be installed in powers of 2:
0, 1, 2, or 4 base modules in a QBB.
• Although mixed-capacity memory modules may be configured, the highest bandwidth is achieved when a QBB is populated with eight identical arrays:
four base modules and four upgrades. The next-highest bandwidth would be four base modules (four arrays).
• If it is not possible to match the capacities of all the arrays, the next best choice is to configure pairs of identical base modules, or base
module/upgrade combinations. For example, a configuration of two 2-GB base modules
(3X-MS8AA-CB), each with a 1-GB upgrade (3X-MS8AA-BU), is a better choice than a configuration of three
2-GB modules (3X-MS8AA-CB).
