drop-down list.

.
The controller performs a low-level disk initialization to check for bad sectors and set up the
RAID parity. The lights on the disks flicker while this process occurs, and the Active Tasks
dialog box shows the progress of the initialization.
If using background initialization (BGI), it is possible to use the new System Drive immediately.
The new System Drive will be initialized non-destructively as soon as any other initializations,
consistency checks, and rebuilds are complete. However, until BGI has finished, RAID parity
will not be correct, and the data on the System Drive will be lost if a disk should fail.
Performance will be lower than usual while BGI is in progress.
If the BGI is not enabled, the system will immediately start to initialize the new System Drive. It
is possible to use other System Drives as normal, but the new System Drive cannot be used
until initialization is complete.
To Verify the System Drive
From the
Home
page, click
Storage Management
page. Then, click
System Drives
.
On the
System Drives
page, the newly added System Drive should appear. Under the Status
Column, the status of the System Drive displays if it is formatting or initializing.
Once the System Drive has been initialized, a file system can be created. For more information
on how to set up a file system, see "
To Create a Silicon File System
".
5
up to 2 TB
Independent data disks with distributed parity blocks.
Employs a combination of striping and parity checking. The
use of parity checking provides redundancy without the
overhead of having to double the disk capacity.
If a physical disk fails and a hot spare disk is available, the
controller automatically inserts the spare and builds onto it
the contents of the failed disk from data and parity
information on the remaining disks. For many applications,
RAID 5 offers the best compromise between capacity,
reliability, and speed.
10
up to 2 TB
Mirrored Stripes.
Combines RAID levels 1 (mirroring) and 0 (striping): disks are
mirrored for redundancy, and data is striped across multiple
disks. However, only half the total capacity of the physical
disks is used for the System Drive. If a physical disk fails and a
hot spare disk is available, the RAID controller automatically
inserts the spare and builds onto it the contents of the failed
disk from the mirrored data.
