Understanding
Disk Storage
Methods
LD
or IoLA, an Apple Power Mac, and Final Cut Pro 4, together offer the most
Io
cost-effective set of features and incredible performance for Video/Audio
production applications. However, to ensure performance and quality, the disk
storage system used with the Apple Power Mac must be able to meet the demands of
storing realtime uncompressed media. At the very minimum, the disk storage
system must be able to provide and maintain a consistent 50 MB/s transfer rate
from the Power Mac to disk (read/write). There are a variety of system
configurations and peripherals that can provide this level of performance. Possible
system configurations are listed below:
Storage MethodFeatures/LimitationsCost
Xserve RAIDFeatures up to 14 ATA/100
drive channels, dual
independent RAID controllers,
and a dual 2Gb Fibre Channel
host interface. Xserve provides
up to 3.5TB of storage with

megabytes per second.

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.
Note: FireWire drive solutions are not generally supported in use with AJA IoLD and
LA
. Since they connect to the host Power Mac via FireWire and use the FireWire bus
Io
bandwidth extensively, it cannot also be used for storage—at the same time. The only
exception is a portable Powerbook implementation where a PCMCIA FireWire card
provides an additional two ports; see the discussion on the PowerBook configuration
provided in this manual. You can however attach and use FireWire drives on the
Power Mac whenever Final Cut Pro is not in use. Their presence on the bus will not

About RAIDs
Redundant Array of Independent Disks, or RAID, is a group of hard drives that
appears to the host Power Mac as a single high-speed storage unit. RAID systems
enable you to increase storage capacity and get the performance, reliability, and data
protection needed for video production, but not possible from a single hard drive.
RAID drives inside the array operate simultaneously, increasing overall throughput.
RAID technology is comprised of these techniques (some or all):
• Striping data across multiple drives for storage performance (RAID 0).
• Mirroring for redundancy (RAID 1).
9
• Parity for data protection (RAID 5 [plus others]).
1
Most RAID configurations, or RAID levels, combine these to provide a balance of
protection and performance.
Striping divides a logical drive into data blocks, or stripes, that are distributed across
an array of physical drives. Striping a set of disks improves storage performance
because each drive operates concurrently. However, striping alone, known as RAID
level 0, offers no data protection.
Mirroring involves writing identical copies of all data to a pair of physical drives. This
results in very high data reliability: If one drive fails, the data is still available on the
remaining disk drive. However, it also results in a storage efficiency of only 50 percent,
because two physical drives are required to achieve a single drive’s capacity. Mirroring
alone is known as RAID level 1.
Parity provides data protection without requiring complete duplication of the drive
contents. In the event of a drive failure, parity information can be used with data on
surviving drives to reconstruct the contents of a failed drive. Parity data can be stored
on a dedicated drive, as in RAID 3, or distributed across an array of drives, as in
RAID 5. Parity provides much greater storage efficiency than mirroring—up to 85
percent for a set of seven drives.
Software For Striping
AJA recommends the Disk Utility software provided by Apple with OS X for creating
and striping RAIDs, including 3rd-party, SCSI, and Xserve RAIDs. It is very easy to
use and has been tested to work well. The utility can be found in Macintosh HD/Applications/Utilities, where “Macintosh HD” is the name of the system drive.
Note: Journaling should be turned off on drives used for realtime video.
10
AJA IoLD/IoLA and Xserve RAID
For the optimum in disk storage with Final Cut Pro 4 and Io
LD
or IoLA, 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 7200RPM 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 IoLD, 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.
