up a Memory Channel cluster interconnect in Cluster Hardware
Configuration.
• To install and configure a local area network as the cluster interconnect,
see the Cluster LAN Interconnect manual.
______________________ Note _______________________
You may save time if you install host bus adapters for shared
storage, cluster interconnect cards (either Memory Channel or
Ethernet cards for a private LAN), and extra Ethernet cards all
at the same time.
3.3 Installing and Configuring Shared Storage
The shared storage for your cluster can be any of three different technologies:
• Fibre Channel (HSG60 and HSG80 RAID array controllers).
• UltraSCSI components (HSZ70, HSZ80, or RAID Array 3000 with an
HSZ22 controller connected to a DWZZH-03 or DWZZH-05 UltraSCSI
hub). Although the UltraSCSI BA356 could be considered in this group,
it is not discussed here because it cannot be connected to an UltraSCSI
hub.
• Non-UltraSCSI components (BA350 and BA356). The UltraSCSI BA356
is discussed in this group.
The following sections provide more information on a TruCluster Server
configuration using each of the three categories of storage.
3.3.1 TruCluster Server Configurations Using Fibre Channel for
Storage
If your shared storage consists of HSG60 or HSG80 RAID array controllers
connected to a storage array network (SAN) and KGPSA-CA Fibre Channel
host bus adapter, review the restrictions in Section 2.2.2, see Section 3.4,
and see the chapter about using Fibre Chanel storage in Cluster Hardware
Configuration for installation information.
Figure 3–1 shows an example of a no-single-point-of-failure (NSPOF) Fibre
Channel configuration using HSG80 RAID array controllers. Either a
Memory Channel interface or a private LAN can be used as the cluster
interconnect.
