Hi all, In few weeks I'll be moving entire Exchange server into new enterprise-class storage array. Currently its working on single RAID 5 volume what for sure is not optimal. I'll have opportunity to make final word what and where put and also what RAID should be used. I'm thinking about RAID 0+1 volumes, however I'd like to use experts experience how to divide exchange logs and databases to achive optimal performance. Its clustered Exchange 2000 with about 1000 users, using mostly Outlook XP, currently about 80 GB of mail data and about 20 GB in public folders. Any input will be appreciated.
