Looking for recommendations on what RAID setup to use on a T610, PERC6i controller. We typically use RAID1-OS and RAID5-Data in our enviornment and heard that RAID6 will give us better redundancy at a cost of performance. Our current PE2900 servers setup with Win2003 host and VMware Server with a RAID1-OS and RAID5-Data, (virtual disks are located on the Data partition) tend to give us VM performance issues as it is. We currently have local backup to disk in addition to remote backups and would like to know if the performance hit is worth the added redundancy.
