• For AlphaServer 2000 systems, the B2111-AA module must be at
Revision H or higher.
For AlphaServer 2100 systems, the B2110-AA module must be at
Revision L or higher.
Use the
examine console command to determine if these modules are
at a supported revision as follows:
P00>>> examine -b econfig:20008
econfig: 20008 04
P00>>>
If a hexadecimal value of 04 or greater is returned, the I/O module
supports Memory Channel.
If a hexadecimal value of less than 04 is returned, the I/O module is not
supported for Memory Channel usage.
Order an H3095-AA module to upgrade an AlphaServer 2000 or an
H3096-AA module to upgrade an AlphaServer 2100 to support Memory
Channel.
• For AlphaServer 2100A systems, the Memory Channel adapter must
be installed in PCI 4 through PCI 7 (slots 6, 7, 8, and 9), the bottom
four PCI slots.
• For AlphaServer 8200, 8400, GS60, GS60E, or GS140 systems, the
Memory Channel adapter must be installed in slots 0-7 of a DWLPA
PCIA option; there are no restrictions for a DWLPB.
• If a TruCluster Server cluster configuration utilizes multiple Memory
Channel adapters in standard hub mode, the Memory Channel adapters
must be connected to separate Memory Channel hubs. The first Memory
Channel adapter (mca0) in each system must be connected to one
Memory Channel hub. The second Memory Channel adapter (mcb0)in
each system must be connected to a second Memory Channel hub. Also,
each Memory Channel adapter on one system must be connected to the
same linecard in each Memory Channel hub.
