4 Installing the Host Bus Adapters for the E2600
Controller-Drive Tray
4.1 Key Terms
HBA host port
The physical and electrical interface on the host bus adapter (HBA) that provides for the
connection between the host and the controller. Most HBAs will have either one or two host
ports. The HBA has a unique World Wide Identifier (WWID) and each HBA host port has a
unique WWID.
HBA host port world wide name
A 16-character unique name that is provided for each port on the host bus adapter (HBA).
host bus adapter (HBA)
A physical board that resides in the host. The HBA provides for data transfer between the host
and the controllers in the storage array over the I/O host interface. Each HBA contains one or
more physical ports.
4.2 Things to Know – Host Bus Adapters and Ethernet Network
Interface Cards
– The E2600 controller-drive tray supports dual 6-Gb/s SAS host connections and optional
host interface cards (HICs) for dual 6-Gb/s SAS, four 1-Gb/s iSCSI, two 10-Gb iSCSI, and
four 8-Gb/s FC connections. The connections on a host must match the type (SAS HBAs
for SAS, FC HBAs for FC, or iSCSI HBAs or Ethernet network interface cards [NICs] for
iSCSI) of the HICs to which you connect them. For the best performance, HBAs for SAS
and FC connections should support the highest data rate supported by the HICs to which
they connect.
– For maximum hardware redundancy, you must install a minimum of two HBAs (for either
SAS or FC host connections) or two NICs or iSCSI HBAs (for iSCSI host connections) in
each host. Using both ports of a dual-port HBA or a dual-port NIC provides two paths to
the storage array but does not ensure redundancy if an HBA or a NIC fails.
– Most of the HBAs, as shipped from the vendor, require updated firmware and software
drivers to work correctly with the storage array. For information about the updates, refer
to the website of the HBA vendor.
NOTICE!
You can use the Compatibility Matrix to obtain information about the supported models of the
HBAs and their requirements. Go to

select the desired Developer Partner Program link. Check its Compatibility Matrix to make
sure you have an acceptable configuration.
