Overview
Congratulations on your selection of the Accusys ACUTA 4/4S subsystem. The ACUTA 4/4S
is a high-performance and extremely flexible RAID subsystem. RAID (Redundant Array of
Independent/Inexpensive Disks) is a storage technology used to improve the processing
capabilities of a storage system, providing a combination of reliability and performance. The
ACUTA 4/4S is ideally suited for integration with databases, e-mail, web servers and imaging
systems.
The ACUTA 4/4S is the ultimate approach to a flexible RAID solution. It can manage three
different RAID levels (0, 0+1 and 5) and also offers the option of RAID 5+hot spare. You will
find detailed explanation on the features and suggested uses of these RAID levels later in this
chapter.
The ACUTA 4/4S subsystem features a user-friendly drive carrier design that lets you easily
install four drives. Each drive carrier supports a one-inch high 3.5-inch form factor drive.
Featuring intelligent online recovery, the ACUTA 4/4S lets you hot swap a failed drive: data will
automatically be rebuilt to the new drive without any system down time. The four drive design
allows also one drive to be designated a hot spare: if one of other drives fails, the ACUTA 4/4S
will seamlessly rebuild the failed drive’s data on the hot spare.
