Hey, We are having an exchange on a 2U server with 6 harddisks slot. We wanted to use 300GB SAS harddisk for as much space as possible. Is RAID10 300GBx4 the best setup? But we have 2 extra harddisk slot. What recommendation do you have? Jackson Yap APC Hosting http://www.apc.sg/

If you want the maximum of space, use a RAID5, then you only lose the capacity of one disk. For a RAID10, you can also use all 6 disks (a mirror of 3 disks in RAID0). The best solution will depend on the IOPS requirements; calculate these using the Exch2010 sizing excel sheet: http://blogs.technet.com/b/exchange/archive/2009/11/09/exchange-2010-mailbox-server-role-requirements-calculator.aspx Peter
