Can't find any definitive information on Cluster Size recomendations for Exchange IS. Have a split backplane, RAID1 sys, RAID5 data. Looking at setting the cluster size to 32k or 64k on the data, as this volume would support the Private and Public IS files. Is there an performance increse in doing this? Thanks, Andy
64K, but more important than the cluster size is to get the logical volume clusters aligned correctly with the disk clusters. Search Technet for a document describing how to format the partition from a command line and assure the alignment.
