Can anyone tell me what Microsoft's recommendation for Hardware on a cluster that is also replicating and log shipping? Or any other ideas? Please see below. host server Controller 1 - Raid 1 Mirror - operating system and SQL application Controller 2 - Raid 5 Transaction logs, and backups - or should these be mirrored and separated? Powervault Raid 10 - for the data and the quorum - or should the quorum be mirrored on a different controller from the data?
