multiple switches to avoid a single point of failure inherent to using a single switch, and to physically isolate replication
traffic from I/O traffic.

The diagram below shows the rear panel of two MSA 1050 controller enclosures with both I/O and replication occurring
on different networks.

Although not shown in the preceding cabling examples, you can cable replication-enabled MSA 1050 systems and
compatible MSA 1040/2040 systems—via switch attach—for performing replication tasks limited to the Remote Snap
functionality of the MSA 1040/2040 storage system.
Updating firmware
After installing the hardware and powering on the storage system components for the first time, verify that the controller
modules, expansion modules, and disk drives are using the current firmware release.
NOTE: Update component firmware by installing a firmware file obtained from the HPE web download site as
described in “Accessing updates” (page 54). To install an HPE ROM Flash Component or firmware Smart Component,
follow the instructions on the HPE website.
Otherwise, to install a firmware binary file, follow the steps below.
Using the SMU, in the System topic, select Action > Update Firmware.
The Update Firmware panel opens. The Update Controller Modules tab shows versions of firmware components
currently installed in each controller.
