I am looking for a way to build a cheap SAN for shared video editing storage. I have QLogic FC HBAs and 3ware Escalade AT RAID controller that shows up as SCSI for operating system. The OS will be Linux and the storage virtualization software I am going to try is Openfilter.Is there any more known cheap/free solution besides above and iSCSI to share/virtualize disks in block mode?
For free Linux stuff for advanced computing, you can download some pretty cool solutions from the NCSA (National Center for Supercomputing Applications). They created a block-based storage/application grid using Linux that scales geographically. Most of the cool block-based virtualization stuff is from vendors so therefore, not free. I did an Internet search a while ago to find a free " global file system" for storage and if I remember correctly, there were a few hits. If you have a budget, you can try Sistina.com for a GFS. SGI also has CXFS. Chris
