|
| Step 5 - Evaluate Configuration Requirements to Support Optional
Partitioning |
| Configuration Requirements for
Partitions |
- Configuring partitions requires some attention to detail with respect to minimum
requirements for option selection, population, and option placement.
|
- A single AlphaServer GS80 Model 8 can be divided into two logical hardware partitions,
each running an instance of Tru64 UNIX V4.0G or Tru64 UNIX V5.1, or an instance of OpenVMS
V7.2-1H1. Each partition is allocated its own dedicated "shared-nothing" set of
hardware resources: QBB(s), CPU module(s), memory module(s), and I/O.
|
- Each hardware partition is viewed as a unique node, from a system point-of-view, with
its own instance of Tru64 UNIX or OpenVMS operating system and application software,
independent system console, and error log.
|
- In the AlphaServer GS80 each of the two hardware partitions is defined by a single QBB.
|
- One system management console (3X-DS8BA-xx) and one console hub (3X-DS8AA-AA) required
per system.
|
- Supported option rules apply for maximum configurations of each AlphaServer GS80 system
partition. Care must be exercised to ensure that any planned reconfiguration of hardware
partitions will not violate option support rules.
|
|
| Minimum Hardware required per
AlphaServer GS80 Hardware Partition |
| Each hardware partition requires
one QBB and that QBB must be configured with the minimum hardware listed below. Each QBB
can be configured with additional hardware once this minimum requirement is met. |
- One Alpha 21264 6/731-MHz CPU module
|
- One 3X-MS8AA-BB/CB/DB memory module (1 GB, 2 GB, 4 GB)
|
- One 3X-KFWHA-BA system I/O module and one 3X-DWWPA-AA master PCI drawer. Depending upon
the configuration, this may require the use of an H9A20-AA/AB/AC expansion cabinet.
|
- AlphaServer GS80 systems are normally configured according to standard module placement
rules, and are shipped with one copy of the operating system installed at the factory
(Tru64 UNIX V4.0G, Tru64 UNIX V5.1, or OpenVMS V7.2-1H1). However, systems with hardware
partitions offer hardware and software configuration flexibility. Factory Integration
Services (VIS) are recommended to enable custom module configuration and factory
installation of multiple copies of the operating system on hardware partitioned systems.
|
|
| Optimizing System Resources |
| The following configuration
guidelines can be used to improve performance in systems or in each partition of a
hardware-partitioned system. |
- Balance the resources in the system (or hardware partition) based upon the available
backplane space and the proposed option populations:
- Sparsely configured systems, those that are using half or less than half of their
available capacity for CPUs, memory, and PCI drawers, should be configured with the
options concentrated in as few QBBs as possible. For example, a GS80 Model 8 with four
CPUs, four memory modules, and two PCI drawers would usually be configured in the first
QBB. The first QBB would be "active" and the second QBB would be available for
expansion.
- Densely populated systems, those that are using more than half of their available
capacity for CPUs, memory, and PCI drawers, should be configured with the options spread
out across both QBBs.
|
- Configure active QBBs symmetrically, each with CPUs, memory, and PCI drawers.
|
- Configure the I/O adapters so that each active QBB has direct access to the most
frequently accessed data.
|
|
| System Software Required for
AlphaServer GS80 Hardware Partition Support |
| Software Licensing for
Hardware Partitions |
- Base systems include operating system license (Tru64 UNIX or OpenVMS) that licenses up
to two hardware partitions
|
| User and capacity-based licensing
is unaffected by hardware partitions. Examples: |
- If a product is licensed for 200 concurrent users, these users can be split among the
partitions, but cannot exceed 200 total users.
|
- If users have a departmental (license code "G") capacity license for a
product, that license can be loaded into the license databases on each of the hardware
partitions.
|
|
| Licensing Partitioned
AlphaServer GS80 Systems for Both OpenVMS and Tru64 UNIX |
- If the system requires both OpenVMS and Tru64 UNIX operating systems be licensed, one
operating system license is included in the base system and the second is added as a line
item. The second operating system license upgrade, which includes the license for only one
CPU, would be added to the order using the following part numbers. Order appropriate media
and documentation kits from Step 13.
|
|
OpenVMS software
upgrade for GS80 |
QB-63PAG-AG |
|
Tru64 UNIX software
upgrade for GS80 |
QB-595AM-AA |
|
- Only those SMP processors intended for use with the second operating system must be
similarly licensed. Use the following license-only part numbers to add an SMP license for
any CPUs intended for use with the second operating system:
|
|
OpenVMS Alpha SMP
license for GS80 |
QL-MT1A9-6Q |
|
Tru64 UNIX Alpha SMP
license for GS80 |
QL-MT4A9-6Q |
|
- The order of licensing is not important, but the following examples are similarly
constructed for clarity: The configuration starts with a Tru64 UNIX base system part
number and the addition of OpenVMS licenses.
|
Example 1: 8-CPU GS80 system in
which all processors are licensed for both OpenVMS and Tru64 UNIX:
- Base system order would include a DA-A80BA-Ax and seven 3X-KN8AA-AB SMP upgrade CPUs
- Add one QB-63PAG-AG OpenVMS software upgrade and seven QL-MT1A9-6Q OpenVMS Alpha SMP
licenses
|
Example 2: 8-CPU GS80 system in
which all the processors are licensed for Tru64 UNIX and four processors are also licensed
for OpenVMS:
- Base system order would include a DA-A80AA-Ax and seven 3X-KN8AA-AB SMP upgrade CPUs
- Add one QB-63PAG-AG OpenVMS software upgrade and three QL-MT1A9-6Q OpenVMS Alpha SMP
licenses
|
- User and capacity-based licenses would be added for the second operating system
environment as though it were a standalone system.
|
|
| Step 6 - Configure Packaging Options |
| Step 6a -
Redundant (N+1) Power Supplies |
- Power supplies included with Model 4 and Model 8 systems can support all combinations of
CPUs, memory, and I/O that can be configured within the system boxes.
|
- Additional 48V power regulators can be ordered to provide N+1 power redundancy.
|
- For Model 4 systems, order one power supply to achieve N+1 capability; for Model 8
systems, order two power supplies to achieve N+1 capability.
