Disk Storage Solutions—G5 With Xserve RAID
Storage Method Features/Limitations Cost
Xserve RAID Features up to 14 ATA/100
drive channels, dual
independent RAID controllers,
and a dual 2Gb Fibre Channel
host interface. Xserve provides
up to 5.6TB of storage with
throughput of up to 400
megabytes per second.
Expensive, although
the cost per
gigabyte is excellent
when large storage
is needed
External ATA/IDE or SCSI
RAID
Scalable. Performance almost
as good as Xserve, although it
can be more complex to set up
and maintain. Many vendors
offer solutions (too many to list
here; check with your Apple
dealer for SCSI Storage
solutions for details). Although
the connection to the external
RAID chassis is SCSI, the
drives themselves may be
SCSI or ATA. A pure SCSI
array will offer higher
performance at a higher cost.
Moderately
Expensive
