Setup guide

Autodesk Stone Direct XR-series disk arrays provide two types of enclosures: a RAID enclosure (also called
an XR enclosure), and an EBOD enclosure (also called an XE enclosure). Each disk array contains twelve 146
GB, 300 GB, or 450GB hard drives. Autodesk Stone Direct uses hardware RAID to provide high performance,
reliability, and protection against data loss.
Hardware RAID storage configurations require either one RAID enclosure (for 2-loop) or up to two RAID
enclosures (for 4-loop). These configurations may include additional XE expansion enclosures. You can
increase storage capacity by adding disk arrays.
A number of Stone Direct configurations will ensure optimal playback of the most demanding formats:

The following three diagrams illustrate how to cable XR-series hardware RAID storage enclosures. It is
important to cable exactly as illustrated in the diagrams to ensure storage functions properly.
WARNING Do not power on your storage before installing Linux, otherwise the Red Hat installer might attempt
to format the storage array and use it as the system disk.
The following diagram illustrates a 2-loop hardware RAID storage configuration. Dotted lines represent
cabling for additional EBOD enclosures. The F6412E RAID controller supports a maximum of seven expansion
enclosures.
