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 |
| |
Configurable stripe size and write policy per array |
| |
Intelligent drive handling: |
| |
- In degraded mode: skips irreparable blocks to continue rebuild
- In normal operation: data-block verification and repair
|
| |
Host Interface |
| |
- One (1) SCSI-320 channel through two (2) VHDCI 68-pin SCSI ports; SCSI-160 backward compatible
- Concurrent I/O commands
- Tagged command queuing up to 256
- Variable stripe size per logical drive
- Optimization setting for random or sequential I/Os
|
| |
Drive Interface |
| |
- Eight (8) 3Gbps SATA-II, hot-swappable drive trays that accommodate 1-inch pitch, 3.5-inch SATA-I or SATA-II disk drives
- Automatic bad-sector reassignment
- Dedicated bandwidth to each connected drive

- Hard drive
- Violated temperature thresholds
|
| |
Module status LED indicators: |
| |
- Two (2) per drive tray
- One (1) per cooling module
- One (1) per power supply unit
- Three (3) per LCD panel

Module failure alert through I2C bus |
| |
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, 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. |
