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 logical drive.
The self-contained hardware-based RAID logical drive provides maximum performance in a compact external
chassis.
