HP StorageWorks Scalable File Share System Installation and Upgrade Guide Version 2.2

Planning the networks 2–19
• The client nodes join the private partition they belong to and also join the default partition using
a Limited Membership key.
• A single IPoIB interface is configured on the HP SFS servers, and two interfaces are configured
on each client node.
Note that this configuration is not supported for HP XC systems.
• Using the private partitions for the HP SFS traffic.
In such a configuration:
• The client nodes only join the private partition they belong to.
• The HP SFS servers join all the private partitions.
• None of the hosts (client nodes or servers) join the default partition.
• A single IPoIB interface is configured on the client nodes. On each of the HP SFS servers, one
interface must be configured for each client cluster partition that will access the HP SFS system.
• Using both the default partition and the private partitions for the HP SFS traffic.
This configuration is a combination of the other two configurations, and must be used if any of the
client nodes are running a Version 2.4 kernel (for example, where NFS servers are configured to
export file systems—such nodes must be running a Version 2.4 kernel).
Any client systems that are running a Version 2.4 kernel must use the default partition. The HP SFS
system must be configured to use both the default partition and the private partitions.
Section 2.4.3.1.1 through Section 2.4.3.1.3 describe the possible configurations in more detail. In each of
these sections, the following assumptions apply:
• A and B are two client clusters.
• HostA1 and HostA2 are the members of cluster A, using Pkey 0x8001.
• HostB1 and HostB2 are the members of cluster B members, using Pkey 0x8002.
• Sfs1 and Sfs2 are HP SFS servers.
2.4.3.1.1 Configuration 1—using the default partition for the HP SFS traffic
CAUTION: This configuration is not supported for HP XC systems.
In this configuration, the HP SFS traffic uses the default partition. Each client cluster is associated with a
distinct private partition. The client cluster nodes use a limited Pkey (0x7fff) for the default partition, to
disable communication amongst the client nodes over the default partition. The HP SFS servers use a full
membership Pkey (0xffff) for the default partition, to allow traffic between the servers and all client nodes.
Note that in this configuration:
• The nodes in cluster A cannot communicate with the nodes in cluster B.
• The nodes in cluster A and the nodes in cluster B can communicate with the HP SFS servers.
Table 2-1 shows the partition table at the switch.
