Other information |
- Three channels support up to 45 disk drives
- LVDS support for up to 80MBps and cable lengths up to 25M
- EDO Cache
- I2O support
- Hot-swap PCI support
- Year 2000 ready
- 80MHz RISC processor
- ServeRAID software contained on CD-ROM
- Bootable CD-ROM support
- It can transfer data up to 264MBps over the PCI bus when installed in servers supporting 64-bit PCI slots.
- Contains two industry standard .8mm VHDCI connectors for attachment of external SCSI enclosures.
- The third channel can be used to support an additional data storage unit.
- An optional 32MB of battery-backup cache is available to provide additional levels of high-availability to protect data stored in write-back cache in the event of a power outage in the server or a problem that occurs to the adapter itself.
- One internal, industry standard, 68-pin connector
- Three RAID channels
- SPCI connector for optional 32MB Battery-Backup Cache
ServeRAID functions:
- Changing from RAID 0 to RAID 5, or vice versa, without requiring the data to be restored from a backup source.
- Expanding the array by adding up to three physical drives at a time.
- Logical drive size can be increased or left unchanged.
- If left unchanged, additional logical drives can be defined.
- Changing the RAID level on-the-fly from RAID 0 to RAID 5 by adding a drive, or RAID 5 to RAID 0 by removing a drive.
- Changing a two disk drive RAID 1 to RAID 5, on-the-fly, by adding one physical drive.
- Concurrent I/O support allowing logical drives to be accessed by users during LDM.
- Degraded mode support allowing a logical drive in critical mode not to affect LDM if already in progress, or preventing LDM start if the drive is in critical model prior to start of LDM.
- Power failure recovery allowing LDM activity recovery even after a power disruption.
- Hot-swap rebuild automatically starts rebuilding a replaced disk drive without operator intervention.
- Data scrubbing periodically scans disk services and automatically repairs bad sectors on the disk array to enhance data integrity.
- One step array initialization and synchronization reduces the time to prepare a new RAID 5 array to accept data.
- Auto synchronization automatically initializes drives without user intervention. |
