Failover hardware requirements

Configuring for failover  |  Hardware requirements  |  Installation guidelines and restrictions

Important

To implement fault tolerance, you must use only matched pairs of controllers. The controllers must be identical, including stripe-unit size and the level of BIOS and firmware code.

You can use the following pairs to provide fault tolerance:

Note: If your system has a built-in ServeRAID controller on the system board or an integrated RAID controller, you cannot use the built-in controller or integrated RAID controller in the failover pair.

To use fault-tolerant technology with ServeRAID controllers, you must use one of the following enclosures:
