Management |
| |
Firmware-embedded Java-based GUI RAID manager |
| |
Centralized management of multiple arrays over in-band or Ethernet |
| |
Real-time event notification over email, LAN broadcast, or SNMP traps |
| |
Host-side SES emulation with pass-through to back-end SES emulation |
| |

|
| |
Onboard alarm is triggered when one of the following modules fails: |
| |
- RAID controller module
- Cooling modules
- Power supply unit
- Hard drive
- Serial port communication with PC hyper-terminal
|
| |
Drive Interface |

| |
Single dual loop across 16 drives within enclosure |
| |

| |
Concurrent I/O commands |
| |
Tagged Command queuing up to 256 |
| |
Variable stripe size per logical drive |
| |

| |
Maintenance & Availability |
| |
Firmware rolling upgrade on redundant RAID controllers |
| |
Synchronized cache over dedicated Fibre channel |
| |
Comes standard with a Li-ION battery module |
| |
Immediate array availability |
| |
Drive roaming, array configuration on drives |
| |
Controller voltage and temperature self-diagnostics |
| |
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:
1. The cached data will automatically be flushed and the array's caching mode will be switched from write-back to write-through
2. Commence an auto shutdown
All environmental thresholds associated with this mechanism are user-configurable and the caching mode changes back to write-back once normal conditions are restored. |
