Technical Specifications I/O Module Configurations The Adaptec SCSI Storage Enclosure supports the following configurations: ■ Single I/O - Split Bus-An I/O module can be located in either I/O module slot. This results in a two-bus backplane, with up to six drives on each bus, with no expansion possible. ■ Single I/O - Joined Bus-An I/O module can be located in one I/O module slot and a Joiner module located in the other slot. This gives a single-bus backplane that supports up to twelve drives. Note: Daisy-chaining JBOD shelves together is not supported. Note: Hot-swapping of the SCSI I/O and Joiner modules is not supported. Cable Lengths Supported The external cable lengths supported for the Adaptec U320 Storage Enclosure are 1, 2, and 5 meters in Ultra320 LVD and Ultra-2 LVD SCSI bus modes. Single-ended SCSI is not supported. SATA Storage Enclosure Technical Specifications Currently Supported Disk Drives Contact your Adaptec sales representative for up-to-date disk drive information. ■ Support for a mix of capacities: 80, 120, 160, 200, and 250 GB. ■ Support for a rotational velocities of 5400, 7200, 10K, and 15K rpm. ■ The disk drives are direct connected to the midplane via an MUX board. ■ The disk drives are connected to the midplane using the host receptacle connector as defined in the Serial ATA specification. ■ Support for 1.0 inch, hot swap, and direct attach disk drives. 8-7

I/O Module Configurations
The Adaptec SCSI Storage Enclosure supports the following
configurations:
■
Single I/O – Split Bus
—An I/O module can be located in either
I/O module slot. This results in a two-bus backplane, with up to
six drives on each bus, with no expansion possible.
■
Single I/O – Joined Bus
—An I/O module can be located in one
I/O module slot and a Joiner module located in the other slot.
This gives a single-bus backplane that supports up to twelve
drives.
Note:
Daisy-chaining JBOD shelves together is not supported.
Note:
Hot-swapping of the SCSI I/O and Joiner modules is not
supported.
Cable Lengths Supported
