Important Notes Regarding Specific Enclosures:

 Apple Xserve RAID:

The Xserve RAID was tested with the 512 MB Cache Module, in a fully populated14 Apple Drive

Configuration, striped across both channels with Apple’s Disk Utility, creating a RAID level 50

storage system. High Definition playback is dependent upon a pre-fetch setting of 128 and real-time

playback is dependent on a pre-fetch setting of 1. Seek rates may not be fast enough for reliable

performance when working with 10 and 16-bit real-time – particularly dual stream – or where more

than 2 streams of 8 bit video are being played simultaneously.

 ADTX ArrayMasStor L Series:

All testing was performed with the Astera Rhino HA Series Fibre card.

 ATTO Diamond Storage Array S-Class for HD:

All testing was performed on the ATTO ExpressPCI FC 3321 Fibre Channel adapter, using driver

version 2.1.1 and ExpressStripe version 2.2 as a striping utility (with interleave set to 256). Seek

rates may not be fast enough for reliable performance when working with 10 and 16-bit real-time –

particularly dual stream – or where more than 2 streams of 8 bit video are being played

simultaneously.

 JMR FORTRA:

When using the JMR FORTRA JBOD enclosures, it is possible to use one or two 4-bay units instead

of an 8-bay unit to reduce the weight of each unit. This makes the system more portable.



HUGE Systems HMV-1800 DualMax:

Seek rates may not be fast enough for reliable performance when working with 10 and 16-bit real-

time – particularly dual stream – or where more than 2 streams of 8 bit video are being played

simultaneously.

 La Cie Big Disk Extreme:

Real-time multi-stream playback is dependent on two units being striped together, with one unit on

the built-in FireWire port and the other on a La Cie FW800 PCI card (or across two FW800 PCI

cards). Even more real-time effects (more streams, time remapping and RGBA composites) can be

achieved with 4 striped units (two per channel). Although capturing uncompressed high definition is

not feasible with this technology, HD playback can be achieved (most effectively when the built-in

FW800 port is used for one channel).

 Medéa VideoRaid RT3X:

Users may encounter Edit to Tape failures when 4 channels of audio are being read from disk while

a rendered video file is also being read. Pinnacle Systems has found that manually mixing the audio

(through an export) to two tracks averts the issue (the Final Cut Pro software audio mixdown

function is not sufficient in this case).

 Medéa VideoRaid RTS, RTR and RTRX:
