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
|

Indicators |
| |
Onboard alarm is triggered when one of the
following modules fails: |
| |
- RAID controller module
- Cooling module
- Power supply unit
- Hard drive
|
| |
Notification Processing Center (NPC) for real-time
event notification over email, LAN broadcast, or
SNMP traps |
| |
Module status LED indicators: |
| |
- Two (2) per drive tray
- Two (2) per cooling module
- One (1) per power supply unit
- Three (3) per LCD panel
- Six (6) per RAID controller module
|
| |
Module failure alert through I2C bus |
| |
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. |

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. |
