GFS/Linux sounds like a interesting lower cost RAC alternative. Please keep us updated on this.

TIA

Steve, The GFS is certified for both 9.0.1 and 9.2.0 but it will depend on the version of Linux and HW vendor you are using. It is my understanding that Redhat AS 2.1 doesn't support direct I/O but RH 7.1 and all versions of SUSE (including SLES) do support direct I/O (not Sure about Rh 7.2 or 7.3). The other issue the HW vendor, DELL's certified cluster configuration only supports RH 7.1 and Oracle 9.0.1 RAC and should support AS 2.1 and 9.2 RAC sometime in September. I am not sure about Compaq intel clusters becuase I only have Dell 6450's and the EMC FC4700 SAN. I am currently working with Sistina to get their GFS but I do not have it installed at this time. I am not sure when AS 2.1 will support direct I/O but I know Oracle and Sistina are working with RH on this issue.

I am also using RAC 9.0.1 and 9.2.0 on SUN clusters using the new Veritas CFS and I am happy with the Veritas DBE/AC product and SUN configuration.

I am a Linux fan but in my opinion, getting Intel certified clusters with various versions of Oracle and Linux is harder than getting HP, Compaq Tur64 (HP?) or SUN certified cluster configurations for Oracle.
