What little documentation that there is for Gluster doesn't include anything regarding system requirements -- minimum or recommended. We're trying to spec-out a setup using four SAN storage units: two NexSans (30T SATAbeast and 10T SATAboy) and two FalconStors (32T NSS650 and 32T NSS620), all connected via iSCSI. These supply storage for two RHEL5 compute clusters (17-node Penguin and 3-node IBM x3950m2) and 300+ user secure file share. Without "real" documentation -- conceptual and otherwise -- it's damn difficult to decide. Is Gluster cpu-intensive, memory heavy, or a mix of the two? And bricks! Is a 10T SAN unit a "brick", or a "block" (or several "bricks")? and does it matter? How many bricks can/could/should a Gluster server node serve? I could spend weeks searching through the mailing-list archives, but that's the purpose of documentation. Frankly, we're at a loss. Is there information to be found, and, if so, where is it? -- JONATHAN B.
