I/O Data Path Protection

You can have multiple host-to-array connections for a host. Ensure that you select all the connections to the array when configuring host access to the storage array.

NOTE: See the Deployment Guide for more information on cabling configurations, at dell.com/support/manuals.

NOTE: For maximum redundancy, you must select all host connections to the array when manually defining host topology. For example, a host may have two host connections listed when manually configuring host access. For this host, you would select the two host connections listed in the Available hosts section and add them to the Selected hosts section using the Add button.

NOTE: For more information on configuring hosts see "Configuration: About Your Host" on page 89.

If a component such as a RAID controller module or a cable fails, or an error occurs on the data path to the preferred RAID controller module, the virtual disk ownership is moved to the alternate non-preferred RAID controller module for processing. This process is called failover.

Drivers for multi-path frameworks such as Microsoft Multi-Path IO (MPIO) and Linux Device Mapper (DM) are installed on host systems that access the storage array and provide I/O path failover.
