RAID |
| |
Multiple arrays configurable with dedicated or
global hot spares |
| |
RAID levels supported: RAID 0, 1 (0+1), 3, 5, 10,
30, 50, NRAID and JBOD
|
| |
Online expansion by:
|
| |
- Adding new drives
- Copying and replacing drives with drives of
larger capacity
|
| |
Automatic background rebuilds
|
| |

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. |
| |
Task
Scheduler |
| |
The Task Scheduler is combined with Media Scan so
that the scanning operation can be scheduled
beginning at a specified start time and repeating at
the configurable intervals. The operation is thus
hands free. Each such schedule can be defined to
operate on individual hard drives, all drives of a
certain class, all member drives of a specified
logical drive, or all member drives of all logical
drives. |
