Server Fault Tolerance

Several types of fault tolerance are available with the ProLiant 800 server,
including:

Disk Subsystem Fault Tolerance

If you are using the optional Compaq SMART-2 Array Controller, you can
specify the level of disk subsystem fault tolerance on your Compaq ProLiant
800 Server. Your fault tolerance options are:
RAID 0 − Data striping with no fault tolerance
RAID 1 − Drive mirroring
RAID 4 − Data guarding
RAID 5 − Distributed data guarding
Use the Array Configuration Utility to select the desired RAID level.

Memory System Error Correction

The ProLiant 800 memory system uses Error Checking and Correcting (ECC)
memory to detect and correct all single-bit memory parity errors. This ensures
the correction of common memory errors without interrupting system
operation.
