| Mike M writes "SQLTeam,We need a SQL Server solution that provides the highest degree of availability. At this point, I have implemented a two-node, active/passive sql cluster, using a RAID 5 shared disk resource. I will be implementing log shipping to another site using the same configuration. We are using SCSI RAID controllers that have at least two channels to the RAID backbone. We have 10 disks on a Dell PowerVault. 2 disks in the Quorum, 2 disks for the log (and tempdb), 6 disks for the RAID 5 data files. From what I understand, the "single point" of failure here is the RAID backbone. Question: If I implement RAID 0+1 (by adding another 10 disks), can this overcome the single point of failure mentioned above? In other words, If RAID 0+1 is implemented, are the mirrored arrays on two different RAID backbones? Any comment, discussion, whitepapers, or links is appreciated.Thanks, Mike M" |
