| RAID |
|
Multiple arrays each with an independent
RAID level
Dedicated, enclosure-specific, or global
hot spares.
RAID levels: RAID 0, 1 (0+1), 3, 5, 6,
10, 30, 50, 60, and NRAID
Online RAID level migration
Online expansion by:
Adding new drives
Copying and replacing drives with drives
of larger capacity
Automatic background rebuilds.
Independent array stripe size and write
policy
Intelligent drive handling
Degraded mode: skips irreparable blocks
to continue rebuild
Normal: data-block verification and repair
|
| Intelligent
Drive Handling |
If two bad
blocks occur on two member drives of an array, the integrity
of the stored data is endangered. Media Scan, Infortrend's
innovative intelligent drive handling function, retrieves
data from the damaged sectors. Media Scan handles low quality
drives in both the degraded mode and during the rebuild
process. For additional data security, other intelligent
drive management features include the transparent resetting
of hung hard drives, power-failure management, and bad-drive
handling during LD expansion.

| Auto
switch cache policy and Auto shutdown |
When a RAID
controller detects conditions exceeding preset thresholds,
the following actions will be exerted to protect the hardware:
Cached data is automatically flushed
and the array’s caching mode switches from write-back
to write-through mode.
If conditions persist past the preset
period of time, auto shutdown of the controller will commence.
All thresholds associated with this mechanism are user
configurable and, once a subsystem manager restores the
normal operating conditions, the caching mode changes
from write-through back to write-back mode.
