Fault-Tolerance The MegaRAID fault-tolerance features are:

•  built-in 9-pin berg connector that provides an RS-232C serial communication interface

•  automatic failed drive detection

•  automatic failed drive rebuild with no user intervention required

•  hot swap manual replacement without bringing the system down

•  SAF-TE compliant enclosure management

•  cache memory

Detect Failed Drive The MegaRAID firmware automatically detects and rebuilds failed drives. This can be done

transparently with hot spares.

MegaRAID supports the manual replacement of a disk unit in the RAID subsystem without system
shutdown.

MegaRAID compatibility issues include:

•  server management

•  SCSI device compatibility

•  software compatibility

Server Management As an SNMP agent, MegaRAID supports all SNMP managers and RedAlert from Storage

Dimensions.

SCSI Device Compatibility MegaRAID supports SCSI hard disk drives, CD-ROMs, tape drives, optical drives,

DAT drives and other SCSI peripheral devices.

All SCSI backup and utility software should work with MegaRAID. Software that has been tested
and approved for use with MegaRAID includes Cheyenne®, CorelSCSI®, Arcserve®, and
Novaback®. This software is not provided with MegaRAID.

Clustering Support LSI Logic provides OEM-optional firmware with multi-initiator support. This software

provides high system availability by permitting server failover.

MegaRAID features were discussed in this chapter. In the next chapter, MegaRAID configuration
is described.
