Required equipment

When you receive your HA pair , you should receive the equipment listed in the following table. See the Hardware Universe at hwu.netapp.com to confirm your storage system type, storage capacity, and so on.

Required equipment	Details
Storage system	Two of the same type of storage systems
Storage	See the Hardware Universe at hwu.netapp.com
HA interconnect adapter (for controller modules that do not share a chassis) Note: When 32xx systems are in a dual-chassis HA pair, the c0a and c0b 10-GbE ports are the HA interconnect ports. They do not require an HA interconnect adapter. Regardless of configuration, the 32xx system's c0a and c0b ports cannot be used for data. They are only for the HA interconnect.	InfiniBand (IB) HA adapter (The NVRAM adapter functions as the HA interconnect adapter on FAS900 series and later storage systems, except the 32xx systems)
For SAS disk shelves: SAS HBAs, if applicable For DS14 disk shelves: FC-AL or FC HBA (FC HBA for disk) adapters, if applicable	Minimum of two SAS HBAs, two FC-AL adapters, or their equivalent in onboard ports
Fibre Channel switches, if applicable	Not applicable
SFP (small form-factor pluggable) modules, if applicable	Not applicable
NVRAM HA adapter media converter	Only if using fiber cabling
Cables (provided with shipment unless otherwise noted)	For systems using FC disk shelf connections, two optical controller-to-disk shelf cables per loop For systems using SAS disk shelf connections, two SAS controller-to-disk shelf cables per stack Multiple disk shelf-to-disk shelf cables, if applicable For systems using the IB HA interconnect adapter, two 4xIB copper cables, two 4xIB optical cables, or two optical cables with media converters Note: You must purchase longer optical cables separately for cabling distances greater than 30 meters. The 32xx systems, when in a dual-chassis HA pair, require 10 GbE cables (Twinax or SR optical) for the HA interconnect.
