Fault Tolerance; Initialization; Selecting An Application; Preliminary Steps - ATTO Technology FastStream SC 5500E Installation And Operation Manual

However, if you require maximum fault
tolerance, it is best practice to have a Hot Spare
available to supply the unallocated drive for
immediate use. Refer to
adding or removing Hot Spares

Fault Tolerance

Choose either Standard Fault Tolerance (no Hot
Spare drives) or Maximum Fault Tolerance (which
adds Hot Spares to the system) when creating parity
RAID Groups. Refer to FastStream process: adding
or removing Hot Spares on page 37 for details.

Selecting an application

After initializing drives or setting up new storage,
select an application from the Initial Setup or via the
Manage page. The FastStream finds all available
drives and creates the appropriate setup using those
drives.
The most flexible choice is to use Custom Setup, but
you must understand your needs and your system well
to use this option.
Refer to Design RAID Groups
Appendix for more information about RAID.

Initialization

If you have not already initialized your drives as
outlined in Ensure Drive Integrity
may choose to use the Advanced Initialization for
new drives to erase and verify drive media and correct
some soft drive errors. The RAID Group is unavailable
until the operation completes.
Choose Express Initialization to perform a quick
background initialization if you have already
completed a full initialize and verify operation. The
RAID Group being initialized is available for use during
express initialization.
Note
DVRAID is only available using the Quick
Digital Video setup wizard.
• General Digital Video: provides parity RAID
protection for digital applications for
configurations using three or more drives.
• Audio: Audio track streaming technology
provides parity RAID protection while managing
latency to allow high-speed availability to
support up to 192 tracks of 16-bit audio or 96
tracks of 24-bit audio in a single editing session.
You must have only 4, 6, 8 or 12 drives available
in the system.
• General IT: provides parity RAID protection
optimized for random access applications using
three or more drives.
• Database: provides parity RAID protection for
database applications (small transfer, random
access) for configurations using more than three
drives.
