Installing the storage subsystem configuration
Before attempting to attach hosts to the storage subsystem, make sure that the
host systems and host bus adapters (HBAs) are installed correctly and updated with
the latest firmware and drivers.
Notes:
1. See the documentation that comes with the HBA for installation requirements
and procedures.
2. Use the correct HBA firmware and device driver. For the latest supported HBAs
and device drivers, consult the readme that comes with the DS3500 controller
firmware.
For a SAS attached host, attach a SAS cable to each HBA. Continue with
“Connecting SAS hosts to the DS3500” to connect the other end of each cable to a
controller.
For a Fibre Channel attached host, attach a fibre channel cable to each HBA.
Continue with “Connecting Fibre Channel hosts to the DS3500” on page 53 to
connect the other end of each cable to the controller.
For an iSCSI attached host, attach an Ethernet cable to each host. Continue with
“Connecting iSCSI hosts to the DS3500” on page 59 to connect the other end of
each cable to the controller.
Connecting SAS hosts to the DS3500
The DS3500 can support up to 28 hosts when attached to the SAS Connectivity
Module for IBM BladeCenter and up to four hosts in a direct attached host
environment. The number of supported hosts depends on the number of host ports
