We are preparing to test that configuration (DS4700 + IBM x3650 + Qlogic HBA's + RHEL 5.4 x64) in cluster mode (2 servers = 4HBA's + 2FC switches + 1 DS700 Array) with Oracle RAC. What is the DS4700 Firmware Version and what is the subsystem "type" (or Host Type) for your devices: LNXCLVMWARE or LINUX ? Krzysztof
