Connecting hosts
IMPORTANT:
Remote Snap must be licensed on all systems configured for replication, and the controller
module firmware version must be the same on all systems licensed for replication (see
Single-controller configuration
Multiple servers/single network/two switches
The diagram below shows the rear-panel of two P2000 G3 10GbE iSCSI MSA Systems featuring 10GbE
iSCSI host interface connection and 10GbE iSCSI-based replication, with both I/O and replication
occurring on the same network.

Connecting two storage systems for Remote Snap — multiple servers/switches/one location
The diagram below shows 1Gb iSCSI host interface connection and 1Gb iSCSI-based replication, with
both I/O and replication occurring on the same network.

For iSCSI-based replication, the iSCSI ports should be connected to at least one iSCSI switch. For optimal
protection, iSCSI ports used for I/O on each controller module should be connected to one iSCSI switch
and iSCSI ports used for replication on each controller module should be connected to a second iSCSI
switch. Both switches should be connected to a single IP network. Using two iSCSI switches in tandem
avoids the potential single point of failure inherent to using a single iSCSI switch.
Dual controller configuration
The following illustrations provide conceptual examples of cabling to support Remote Snap replication.
Once the P2000 G3 MSA 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 HP P2000 G3 MSA System SMU Reference Guide for more information about using Remote
Snap to perform replication tasks. SMU’s Replication Setup Wizard guides you through replication setup.
