The SAS connector on each end of the SAS cable needs to match the two types of NetWitness hardware been connected together.

Example 1

Connecting a PowerVault (MD 1400) to a NetWitness S6 appliance use a mini-SAS HD (SFF-8644) to mini-SAS HD (SFF-8644) cable.

Example 2

When connecting a DAC (VNX5400) to a NetWitness S5/S6 appliance use a mini-SAS HD (SFF-8644) to mini-SAS (SFF-8088) cable.

Example 3

When connecting a DAC (VNX5400) to a NetWitness S4S appliance use a mini-SAS (SFF-8088) to mini-SAS (SFF-8088) cable.
