HP ProLiant Cluster HA/F500 for MA8000 Enhanced DT Supplement Guide

Cluster Installation
Data Replication Manager
Refer to the Data Replication Manager HSG80 ACS operations guide for detailed
information on the DRM including any restrictions. Table 2-1 outlines the restrictions
that are specific to the HA/F500 Enhanced DT cluster configuration.
Table 2-1: DRM Restrictions
Restriction Implication
There is a maximum of four clusters per set of
four Fibre Channel switches. One node must be
located at each site for each of the clusters.
The HA/F500 Enhanced DT cluster
configuration does not support configurations
that exceed these limits.
A maximum of four storage subsystems is
permitted in an HA/F500 Enhanced DT cluster
configuration.
There is a maximum of two storage subsystems
per site.
TCP/IP addresses on each cluster node
assigned to the dedicated MSCS heartbeat link
must be on the same IP subnet.
Any network card supported by Microsoft
operating systems may be used for the
dedicated heartbeat link. Alternate network
topologies, such as the FDDI, may have to be
used to keep the two nodes on the same IP
subnet because of the long distances between
the two cluster nodes.
There is a maximum of eight remote copy sets
per cluster.
The HA/F500 Enhanced DT cluster does not
support configurations that exceed these limits.
There is a maximum of 12 remote copy sets
per storage subsystem initiator-target pair.
In a configuration with multiple clusters, each
cluster is limited to using eight remote copy
sets. For all combined clusters, 12 remote copy
sets are available for each storage subsystem
initiator-target pair. In the maximum supported
configuration of the two storage subsystems
initiator-target pairs, there are 24 available
remote copy sets for all of the clusters (for
example, with four clusters, each cluster can
use six remote copy sets).
