StorNext is a proprietary product that appears to have its own drivers and management tools. If you want documentation, ask the vendor for it.Now with this said, I am searching for documentation on operating a SAN under linux. We are looking at Quantum StorNext FS2 product for the SAN itselft.Is there any other solution for building a SAN under linux ?
We're using a somewhat aged HP StorageWorks EVA3000 SAN and a 2 Gb fibre channel infrastructure with our CentOS 4 servers running the Red Hat Cluster Suite to support several instances of Oracle. The hardware includes Qlogic FC controllers and Brocade FC switches. It actually works quite well, though the versions of RHCS for RHEL/CentOS 4 are a bit complicated for today's needs.
We are currently working to migrate this to an EMC CX4 SAN on an 8 Gb fibre channel infrastructure with Dell blade servers. We're using RHEL 5 and Oracle's cluster toolkit and it seems quite an improvement over RHCS and GFS2. OCFS2 seems to have caught up with GFS2 as far as capabilities go and is laughably simple to configure compared to RHCS 4. Of course, with it working so well we haven't had much opportunity to develop troubleshooting skills.
We also use a LOT of iSCSI SAN connections, using either iSCSI servers from HP or Dell or general-purpose machines running OpenFiler. Performance isn't quite up to the 8 Gb/s SAN speeds, but with Gigabit Ethernet and jumbo frames it's pretty respectable.
