One SCSI raid controller is enough for Raid1 & Raid5. Two Hardisk for mirroring (Raid 1) Four Hardisk for Strip set & parity (Raid 5).

My questions are - I want to use raid 0+1 or raid 10(deoending on price) for the trans logs. I want to keep the exchange binaries and db seperate from the logs on a raid 5. To do this, do i need 2 raid controllers or can i just do this with 1? alos the proliants seem to only support 6 drives and for this solution i will need at least 7. Has anyone had experince with doing this on proliants with the smart array 6i controller? Thanks a lot ------------------------------------------------------ List Archives: http://www.webelists.com/cgi/lyris.pl?enter=exchangelist Exchange Newsletters: http://www.msexchange.org/pages/newsletter.asp Exchange FAQ: http://www.msexchange.org/pages/larticle.asp?type=FAQ ------------------------------------------------------ Other Internet Software Marketing Sites: World of Windows Networking: http://www.windowsnetworking.com Leading Network Software Directory: http://www.serverfiles.com No.1 ISA Server Resource Site: http://www.isaserver.org Windows Security Resource Site: http://www.windowsecurity.com/ Network Security Library: http://www.secinf.net/ Windows 2000/NT Fax Solutions: http://www.ntfaxfaq.com ------------------------------------------------------ You are currently subscribed to this MSEXchange.org Discussion List as: SMahadevan@xxxxxxxxxxxx To unsubscribe visit http://www.webelists.com/cgi/lyris.pl?enter=exchangelist Report abuse to listadmin@xxxxxxxxxxxxxx
