                          Astra ES Overview  Astra ES provides data storage solutions for applications where high performance and data protection are  required. The failure of any single drive will not affect data integrity or accessibility of the data in a RAID  protected logical drive.       A defective drive may be replaced without interruption of data availability to the host computer. If so configured, a  hot spare drive will automatically replace a failed drive, securing the fault-tolerant integrity of the logica

                        Architectural Description  The Astra ES is a Fibre Channel or Serial Attached SCSI (SAS) host, SAS+SATA disk, subsystem suitable for  Direct Attached Storage (DAS), Storage Area Network (SAN), and Expanded Storage.    Only hard disk drives from Excel Meridian Data are approved for use in this solution.    All enclosures include a mid-plane, RAID controller, power and cooling units, and enclosure processor all in one  cable-less chassis design. Multiple fans and power supplies provide redundancy

                        Configurable RAID stripe size: 64 KB, 128 KB, 256 KB, 512 KB, and 1 MB stripe size per logical drive.  Background task priority tuning: Adjustment of minimum I/O reserved for server use during all background tasks.  Hot spares: Multiple global or dedicated hot-spare drives with revert option.  Maximum LUNs per subsystem: 256 in any combination of RAID levels.  Maximum LUNs per array: 32 logical drives (LUNs). Supports LUN carving by allowing an array to be divided into  multiple logical drives.

                        Mounting Astra ES in a Rack  The subsystem installs in the rack using the supplied mounting rails.         Cautions  • At least two persons are required to safely lift, place, and    attach the Astra ES enclosure into a rack system.  • Do not lift or move the Astra ES enclosure by the handles,  power supplies or the controller units. Hold the enclosure  itself.  • Do not install the Astra ES enclosure into a rack without rails  to support the enclosure.    To install the Astra ES enclosure into
