Chapter 1 General Information
This chapter provides general information of the DAS-208SA Disk Array.
The following topics are covered in this chapter:
◆ Introduction
◆ Key Features & Benefits
◆ Unpacking Your SA-2081 Disk Array
◆ Components of DAS-208SA Disk Array
1.1 Introduction
The DAS-208SA is a Serial ATA to Ultra320 SCSI RAID (Redundant Array of
Independent Disks) Disk Array. By implementing sophisticated RAID
technology and unique cache algorithm, this disk array provides the best
protection for the data stored on the array.
And thanks to today’s powerful disk technology, one RAID system can now
provide the capacity more than 1TB in a large cabinet. This offers a wealth of
significant advantages that would be attractive to almost any serious PC users.
Equipped with eight half-height 3.5” disk drives in hot-swappable canisters, the
DAS-208SA Disk Array provides mass data capacity and easy installation for
the individual customers. In addition, this RAID system has dual host channels
and high availability software that ensures 24 hours a day, seven days a week
of nonstop service capability.
Throughout this manual, the DAS-208SA Disk Array may be referred to as
DAS-208SA,or simply as Disk Array.
