EMC cable requirement and configuration for VNX Disk Processor Enclosure (DPE).

By Tekmart Enterprise Support Team

A quick note to clarify SAS cabling between EMC VNX and extra enclosures or DAE’s as they are called.

When setting up a VNX with only the base DPE enclosure, there’s no need for cabling.

When adding the first and the second enclosure, you need a special kind of SAS cable, called the “mini-SAS to mini-SAS HD cables”.
