900731 Data Handling for Eye-in-the-Sea on MARS : EITS RAID This page last changed on Oct 06, 2008 by dcline. The EITS RAID is populated to the maximum allowed for its controller - the RAID cannot be grown. The total formatted usable space is approximately 40 TB. ## Specifications Vendor: Xyratex 840 Embarcadero Drive, St. 80 West Sacramento, 95606 Controller: E5412 Enclosures: 5 enclosures with twelve 750 GB SATA drives per enclosure ## Power up/down instructions Power on expansion chassis first, then controller. Power down in reverse; controller first then expansion chassis. ## RAID configuration Each enclosure is configured as a 11-drive RAID5 array with 1 hot-spare drive. All 5 enclosures are then combined to form 1 LUN. This basically means all the storage on the RAID will be represented as one large drive. ## Cable connections Page 2 of the E5402E quick start guide show how to connect to the host (Single HBA), and how to daisy chain the expansion enclosures to the RAID enclosure.
