I have a Windows Server 2003 R2 server running Exchange Enterprise 2003. The server is built with one RAID5 array. I currently have one Storage Group with one Mailbox Store that is now over 400GB. My backup is taking almost 8 hours. My questions:
1. Is there any reason to divide this one SG and MS other than backup and restore times?
2. If the resommendation is to split them up, what is the benefit of having multiple SCs over multiple MSs? I know I can have four MSs withinin each SG. Should I max out the four MSs before I create a new SG?
3. Since all the bays in my server are already maxed out, creating a second array isn't an option at this time but if I was to buy a new server, what would be your recommendation on configuring it?
