SAS Cabling

The Ultrastar Data102 can use passive cables that are limited to 3m or less, or active cables of any length for

SAS connections to the host. Active cables must be used for Ultrastar Data102 to Ultrastar Data102 daisy

chaining connections. All approved passive and active SAS cables are listed in the following table.

Note:

MegaRAID adapters do not support the use of active SAS cables. If your configuration

requires the use of MegaRAID adapters, passive cables must be used.
