Updating firmware

The diagram below shows host interface connections and replication, with I/O and replication occurring

on different networks. For optimal protection, use two switches. Connect one port from each controller

module to the first switch to facilitate I/O traffic, and connect one port from each controller module to the

second switch to facilitate replication. Using two switches in tandem avoids the potential single point of

failure inherent to using a single switch; however, if one switch fails, either I/O or replication will fail,

depending on which of the switches fails.

Virtual Local Area Network (VLAN) and zoning can be employed to provide separate networks for iSCSI

and FC, respectively. Whether using a single switch or multiple switches for a particular interface, you can

create a VLAN or zone for I/O and a VLAN or zone for replication to isolate I/O traffic from replication

traffic. Since each switch would include both VLANs or zones, the configuration would function as multiple

networks.

Multiple servers/different networks/multiple switches

The diagram below shows the rear panel of two MSA 1040 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 1040

and compatible MSA 1040 and P2000 G3 systems—via switch attach—for performing replication tasks.

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. Using

the SMU, right-click the system in the Configuration View panel, and select Tools

Update > Firmware. The

Update Firmware panel displays the currently installed firmware versions, and enables you to update them.

Optionally, you can update firmware using FTP (File Transfer Protocol) as described in the MSA 1040 SMU

Reference Guide.
