Setup guide

11 Once you complete the setup of your Stone Direct storage, if you need to configure Wire

networking,
refer to the Stone and Wire Filesystem and Networking Guide.
XR-Series Disk Array
XR-series refer to the disk arrays used to build the Stone Direct configuration. The XR-series is the new
generation of storage.
XR-Series Disk Arrays
The XR-series includes the XR146, XR300, XE146, and XE300 disk array types. Each XR-series disk array
contains twelve 146 GB, 300 GB, or 450GB hard drives. For technical specifications, assembly, and
maintenance information, refer to the XR/XE RAID Solution Maintenance Guide.
RAID Strategy
Autodesk Stone and Wire uses hardware RAID (Redundant Array of Independent Disks) to provide high
performance, reliability, and protection against data loss. RAID combines many hard disks into a single
logical disk to obtain I/O performance levels that cannot be obtained with a single disk.
RAID operations are performed by a hardware RAID controller included in the disk array enclosure. Hardware
RAID has the advantage of a dedicated CPU that substantially improves throughput and does not impact
workstation performance.
Physical Enclosures
The XR- series provides two types of enclosures: a RAID enclosure and an EBOD (Expansion Bunch Of Disks)
enclosure (also called an XE enclosure).
NOTE RAID and EBOD enclosures are not interchangeable. Each type of enclosure has its own firmware, Ethernet
ports, fibre channel ports and expansion ports (EBOD enclosures use Serial Attached SCSI (SAS) expansion ports).
Also, you cannot mix and match enclosures with different disk sizes; all disks in all enclosures in a storage
configuration must be of the same size, series, and firmware.
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 (XR-series) expansion enclosures.
RAID enclosures contain hardware RAID controllers. The RAID enclosure or enclosures perform RAID
operations for all enclosures in the configuration.
The following illustrations show the XR-series RAID using the F6412E RAID controller and EBOD enclosures.
The F6412E RAID controller is used with the HP xw8600 and HP z800 Workstations only.
