Overview
This technical update to the TruCluster Server Cluster Hardware
Configuration manual provides important information about support for the
AlphaServer ES45 with the TruCluster Server Version 5.1A product.
1.1 General Overview
The AlphaServer ES45 was recently qualified for use with the TruCluster
Server Version 5.1A product.
No TruCluster Server software release coincides with the availability
of support for the AlphaServer ES45, so this technical update adds the
AlphaServer ES45 configuration information that will appear in future
revisions of the TruCluster Server Cluster Hardware Configuration manual.
Use this technical update in conjunction with the TruCluster Server Cluster
Hardware Configuration manual.
1.2 AlphaServer ES45 Overview
The AlphaServer ES45 is a 1000 MHz follow-on to the AlphaServer ES40. It
can employ from 1 through 4 processors.
Only the ES45 Model 2 is presently supported. Other models, with different
PCI/AGP bus configurations, will follow.
A 10-slot PCI backplane provides six slots that support hot-swapping.
______________________ Note _______________________
The Tru64 UNIX Version 5.1A operating system does not support
hot-swapping PCI modules.
The ES45 Model 2 has four PCI buses (hoses). The PCI backplane supports
four 5.0V 33-MHz PCI slots and six 3.3V 66-MHz PCI slots.
The AlphaServer ES45 is available in a tower, pedestal, and rackmount
(M-Series cabinet) configuration.
