Description
To connect to shared disk storage, you
must install either a parallel SCSI or a
Fibre Channel host bus adapter in a PCI
slot in each cluster system.
For parallel SCSI, use a low voltage
differential (LVD) host bus adapter.
Adapters have either HD68 or VHDCI
connectors. Recommended parallel SCSI
host bus adapters include the following:
· Adaptec 2940U2W, 29160, 29160LP,
39160, and 3950U2
· Adaptec AIC-7896 on the Intel
L440GX+ motherboard
· Qlogic QLA1080 and QLA12160
· Tekram Ultra2 DC-390U2W
· LSI Logic SYM22915
· A recommended Fibre Channel host bus
adapter is the Qlogic QLA2200.
See Section A.6, Host Bus Adapter
Features and Configuration Requirements
for device features and configuration
information.
Host-bus adapter based RAID cards are
only supported if they correctly support
multi-host operation. At the time of
publication, there were no fully tested
host-bus adapter based RAID cards.
Refer to http://www.redhat.com for more
the latest hardware information.
SCSI cables with 68 pins connect each host bus
adapter to a storage enclosure port. Cables have
either HD68 or VHDCI connectors. Cables
vary based on adapter type
