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.
Hot Swap
MegaRAID supports the manual replacement of a disk unit in the RAID subsystem without system
shutdown.
Compatibility
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.
Software
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.
Summary
