HP MSA 1040 SAN Storage - Manual (Page 34)

34 Connecting hosts
Once the MSA 1040 systems are physically cabled, see the SMU Reference Guide or online help for
information about configuring, provisioning, and using the optional Remote Snap feature.
NOTE: See the HP MSA 1040 SMU Reference Guide for more information about using Remote Snap to
perform replication tasks. The SMU Replication Setup Wizard guides you through replication setup.
Host ports and replication
MSA 1040 controller modules use qualified SFP options of the same type (FC or iSCSI). Each host port can
perform I/O or replication.
Single-controller configuration
One server/single network/two switches
The diagram below shows the rear panel of two MSA 1040 controller enclosures with both I/O and
replication occurring on the same network. Each enclosure is equipped with a single controller module.
The controller modules use qualified SFP options of the same type, supporting the host interface protocol
ordered from your supplier.
Figure 20 Connecting two storage systems for Remote Snap: one server/two switches/one location
Host ports used for replication must be connected to at least one switch. For optimal protection, use two
switches, with one replication port from each controller connected to the first switch, and the other
replication port from each controller connected to the second switch. Using two switches in tandem avoids
the potential single point of failure inherent to using a single switch.
Dual-controller configuration
Each of the following diagrams show the rear panel of two MSA 1040 controller enclosures equipped with
dual-controller modules. The controller modules use qualified SFP options of the same type, supporting the
host interface protocol ordered from your supplier.
Multiple servers/single network
The diagram below shows the rear panel of two MSA 1040 controller enclosures with both I/O and
replication occurring on the same physical network.
