Processor Compatibility in a Multiprocessor
Environment
DIGITAL recommends using identical steppings/versions of processors within a
multiprocessor system whenever possible, since these configurations have received
the greatest amount of validation testing. Since it is not possible to validate every
combination of processor steppings, each new stepping of a processor is fully
validated only against the latest stepping. Refer to the readme file on the
ServerWORKS Quick Launch CD-ROM to view the latest processor compatibility
information.
Configuration Guidelines
•
Up to four processors (two processors per module) can be installed on the
DIGITAL Server 7100.
•
Use only DIGITAL-supplied processor modules.
•
A processor upgrade can be done either by installing a higher-performance
processor or a processor module.
•
If a second processor module is not installed, a terminator card must be
installed.
•
Processor speed and cache size on a second processor module must be
identical to the primary processor module.
•
Before you begin, create an SCU diskette using the Quick Launch CD-ROM
disc. You must run the SCU after installing any processor upgrade. This
allows the server to recognize the new processor configuration.
