Installing the storage subsystem configuration
Using the information from the previous sections, install the host systems and host bus adapters (HBAs).
Notes:
1.See the documentation that comes with the HBAs for installation requirements and procedures.
2.Use the correct HBA device driver. For the latest supported HBAs and device drivers, go to http://www.ibm.com/servers/storage/support/disk/
Attach a SAS cable to each HBA. Continue to “Connecting hosts to the DS3200” to connect the other end of each cable to a controller.
Connecting hosts to the DS3200
The DS3200 can support up to fourteen hosts when attached to the SAS Connectivity Module for IBM BladeCenter and up to three hosts in a direct attached host environment. The number of supported hosts depends on the number of host ports installed on the DS3200 RAID controller. To protect against the loss of any one path from the host servers to the DS3200 storage subsystem, use redundant host connections.
