IBM DS4000 Storage (formerly known as IBM
FAStT)
Certified by SIOS Technology Corp. with QLogic
2200 and 2340 adapters in both single and
multiple path configurations. Use
theqla2200orqla2300driver, version 6.03.00 or
later, as defined by IBM.When using IBM
DS4000 storage arrays systems with Emulex
FC adapters, use thelpfcdriver versions
specified in theEmulex Driversitem below.
Single path (i.e. single loop) support: In a single
path configuration, a fibre channel switch or hub
is required for LifeKeeper to operate properly.
Multiple path (i.e. dual loop) support: Multiple
paths are supported with the DS4000 storage
array models that are released with RDAC
support (currently the DS4300, DS4400 and
DS4500 models). Fibre channel switches and
hubs are not required with multiple path
configurations with RDAC. RDAC is a software
package that handles path failovers so that an
application is not affected by a path failure. The
steps to install and setup RDAC are slightly
different depending on the version being used.
Refer to the IBM RDAC documentation for the
instructions to install, build and setup.
IBM DS5000
Certified by partner testing in a multipath
configuration using IBM RDAC. Please consult
the IBM website to obtain the supported RDAC
drivers for your distribution.
