NOTES:

Hard partitions of GS80, GS160, and GS320 AlphaServers can be clustered together either across separate systems or within systems, but each hard
partition must have at least one cluster interconnect connection.
TruCluster Server Version 5.1B-1 requires all members to be connected with either all members using Memory Channel hardware or all members
using a private 100 Mbps or 1000 Mbps full-duplex LAN. Note that there are two variants of Memory Channel (MC).
ES45 models 1, 1B, 2, and 2B support single rail Memory Channel (MC) configured for either 512 MB or 128 MB. Dual rail MC is supported with
both Memory Channel adapters placed on the same PCI bus and jumpered to run at 128 MB.
ES45 models 3 and 3B can support dual rail Memory Channel (MC) with both rails configured either for 512 MB or 128 MB. Memory Channel
adapters must be placed on separate PCI busses when jumpered to run at 512 MB.
The use of the MC API is not supported in a two-member cluster containing an AlphaServer ES45 and configured with Memory Channel in virtual
hub mode. To use the MC API in a two-member cluster containing an AlphaServer ES45, a Memory Channel hub must be configured for each rail.
For further information on deploying an ES45 in a TruCluster, refer to the

manual at

1. KZPEA-DB is supported for configuring a shared bus in a TruCluster with a maximum of two members per shared bus. Patch Kit 1 is required. Please
check the specific platform Supported Options Lists to see if a particular platform is supported.

2. The embedded Gigabit Ethernet adapter (10/100/1000Mbps) on the DS25 is supported by TruCluster Server as a LAN cluster interconnect if patch kit 2 is
installed.
3. 3X-DEGXA-SA/TA Gigabit Ethernet adapter is supported by TruCluster Server as a LAN cluster interconnect if patch kit 2 is installed. Please check the
specific platform Supported Options Lists to see if a particular platform is supported.

4. TS20 is supported for two member LAN interconnected cluster only.
5. KZPBA-CC is supported on the ES47s, ES80, & ES1280 for shared bus only with HSZ80 storage.

TruCluster Server Version 5.1 requires all members to be connected using Memory Channel hardware. Note that there are two variants of Memory Channel
(MC):

configuration notes:

configuration notes:

At least one Memory Channel adapter must be installed in a PCI slot in each member system. One or more link
cables are required to connect systems to each other or to a hub. A cluster environment with two nodes does not
require a hub. A configuration of more than two members requires a Memory Channel hub.
MC1and MC1.5 cannot be mixed on the same rail with MC2.

There are special rules about circumstances where Memory Channel 1 and Memory Channel 2 can be used together in the
same cluster. The

TruCluster Server Hardware Configuration

manual provides information regarding supported Memory

Channel configurations.
