and Xserve RAID
For the optimum in disk storage with Final Cut Pro 4 and Io
LD
or Io
LA
, we
recommend Apple’s Xserve RAID. Xserve RAID holds up to 14 hot-swap Apple
Drive Modules—3.5TB of storage—in a rack-optimized 3U enclosure. Each 7200-
RPM hard drive connects to a dedicated ATA/100 drive channel, eliminating a
traditional source of bottlenecks and maximizing the 2Gb/s Fibre Channel host
connection(s). By adding more Xserve RAID systems, you’ll have very large
expansion capabilities: A standard 42U rack can hold over 49TB of Xserve RAID
storage.
Xserve RAID is designed for nonstop operation. Redundant hot-swap power and
cooling modules allow the system to keep functioning even if one module fails. A
high-availability architecture and dual independent RAID controllers support
RAID levels 0, 1, 3, 5, and 0+1. In addition, Xserve RAID supports hybrid RAID
levels 10, 30, and 50 when used in conjunction with host-based software RAID.
Remote Xserve RAID management capabilities are provided via Apple’s Java-based
RAID Admin application.
Note:
When creating and striping an Xserve RAID for Io
LA
or Io
LD
, using the
Apple Disk Utility provided with OS X, use
RAID 50
. The internal Xserve RAID
drives are set up as RAID 5; the Xserve RAID then shows up in Disk Utility as two
drives (regardless of the number of internal drives) which must be configured
together as RAID 0. Apple calls this configuration “RAID 50.”
Storage capacity
No matter which storage system you choose, pick one that can scale to meet your
needs over time. Ideally, you should be able to increase storage capacity or switch to
a RAID level offering increased data protection in the future. Balance current and
future storage needs with your budget and choose accordingly.
Note:
for uncompressed formats, PAL and NTSC transfer rates and storage
requirements are the about the same because PAL has a lower frame rate, but more
lines.
