Cable Lengths

The following cable length information applies to all Oracle ZFS Storage controllers:

Active optical cables (AOCs) are required for attaching Oracle ZFS Storage ZS11-2, ZS9-2, and ZS7-2 controllers to Oracle Storage Drive Enclosure DE3-24 disk shelves. Other controllers and/or disk shelves in the future may use AOC cabling. AOCs are available in the following lengths: 3 meters, 6 meters, and 20 meters. The maximum AOC length between a controller and disk shelves that span further than two adjacent cabinets is 20 meters.
The maximum copper cable length between a controller and disk shelves is 6 meters.
The maximum copper or AOC cable length between Oracle Storage Drive Enclosure DE3-24 disk shelves in a single chain that spans two adjacent cabinets is 6 meters copper, 6 meters AOC, or 20 meters AOC; only one pair of 6-meter cables is allowed per chain.

Note:

The Oracle ZFS Storage ZS11-2 controller does not support DE2 disk shelves or Sun Disk Shelves.

The following cable length information applies to all Oracle ZFS Storage controllers except for ZS11-2:

Oracle Storage Drive Enclosure DE2-24 disk shelf connection to Oracle ZFS Storage ZS7-2 controllers is supported in software release OS8.8.4 and later. Available copper cable lengths between the Oracle ZFS Storage ZS9-2 controller or the ZS7-2 controller and the Oracle Storage Drive Enclosure DE2-24 disk shelf are 3 meters and 6 meters.
The maximum copper cable length between Oracle Storage Drive Enclosure DE2-24 disk shelves that span across adjacent cabinets is 3 meters.
The maximum copper cable length between Sun Disk Shelves that span across adjacent cabinets is 3 meters.
