Host adapters
Each connection from a host port on a controller to a host is made through a host adapter on the host.
A host adapter can be a host bus adapter (HBA) for Fibre Channel or SAS connections, a host
channel adapter (HCA) for InfiniBand connections, or an Ethernet adapter for iSCSI connections.
The host adapter provides the interface to the internal bus of the host. For hardware redundancy, use
two host adapters in each host computer. The two host adapters must be of the same type (HBAs,
HCAs, or Ethernet adapters). For duplex controller shelves, connect each host adapter to a different
controller in the controller shelf to make sure that the server can access data even if one HBA or one
controller fails.
Attention: Possible loss of data access – Do not use a combination of HBAs from different
vendors in the same host. For the HBAs to perform correctly, use HBAs from only one
manufacturer.
You can obtain information about supported host adapters from the NetApp Interoperability Matrix
Tool.

Host interface cards
A host interface card (HIC) is a component of a controller that contains host ports. A controller might
also have host ports, called baseboard host ports, that are not on a HIC. Different types of HICs are
installed in a controller depending on the types of host connections a storage array supports. A HIC is
cabled to a host adapter on a server: a host bus adapter (HBA) for Fibre Channel or SAS, a host
channel adapter (HCA) for InfiniBand, or an Ethernet adapter for iSCSI. The host connection might
be direct or through a switch fabric. The host adapter in the host must support the same interface
protocols as the type of HIC to which it is cabled.
