I am in the process of specing out a high availability Oracle database solution and need some advice from those of you experienced in doing this as to what storage hardware to get. The plan right now is to have 3 Oracle 9i or 10g nodes (2 failover) running on Redhat Enterprise 3.5 or 4.1 with a shared filesystem for Oracle via GFS (6.0 or 6.1 depending on which version of RHEL) We'd also like to use multipathing and 2 mirrored SANS of some sort. The application we will be running requires very very little in terms of storage space, only ~3GB per year, per database. DB load will also probably not be that high. Uptime is critical. So for hardware I have been looking into the following: iSCSI SAN: I've tested a low end (nice price) EMC AX100i /w GFS 6.0 (using GULM) and RHEL 3.5 (4.1 doesn't have iSCSI working yet). Performance was awful... 2.5-5 MB/s writes, 25-30 MB/s reads. So it looks like iSCSI is out of the question unless there is another hardware option that would give me the performance I'd want? Fibre Channel SAN: I've been trying to avoid using a FC solution if I can because of cost but if it's what I need it's what I have to get. Any suggestions on this? Are these reliable enough to safely use just one SAN in a 99% uptime environment? Any good entry/mid model's to look at? AOE (Coraid.com): This looks to be a perfect solution.. low cost and potentially decent performance. It's relatively new and I haven't heard of anyone using it yet though. There doesn't seem to be much out there to tell me what sort I can expect out of these with GFS... Any info would be helpful. -- Linux-cluster@xxxxxxxxxx http://www.redhat.com/mailman/listinfo/linux-cluster
