Hot-swap hard drive bays

The server comes with one hot-swap hard drive cage installed. A second bay is available as an accessory. The hard drive bays each support up to five 3.5-inch by 1.0-inch Ultra320 SCSI hard drives. The hard drive bays also support SCSI hard drive technologies, such as Ultra160 and Ultra2, that are slower than the Ultra320 SCSI technology.

Each hard drive is connected to an Adaptec® Ultra320 SCSI hot-swap backplane. The backplane provides 80-pin SCA-2 connectors for each hard drive and accepts 15,000 RPM and slower SCSI hard drives that consume up to 20 watts of power.

Opening the bezel door provides access to the hard drives. To allow hot swapping, each hard drive mounts in a hard drive carrier. When a hard drive is removed from the system, both the carrier and the hard drive are removed.

Caution! Because all hard drives have different cooling, power, and vibration characteristics, specific hard drive types has been validated to be compatible with the Altos G900 system.
