The customer has 10 XP workstations and one XP computer that is acting as their "server", running a standard IDE har drive. They now want to add workstations on the network, and want to go to Win 2003 SBS on a real server. They are running Accpac accounting, most of which runs off the server (the programs, data, and the database engine to some degree), and they also want to start using Exchange server.
I think I understand the benefits of Raid 1 for mirroring. But what I'm wondering is this: if I use Raid 0 for striping, in this environment will their hard drive access be faster, slower, or about the same? In other words, is it worth doing? Or, should we just stick with a single IDE drive in the new server?
From all the stuff I've read, I get the impression that striping puts various pieces of their files across multiple hard drives, but I don't understand how the computer/operating system/controller--or whatever figures it out--could possibly know how to optimize what is placed where on which drive in order to enhance disk performance. Does it somehow know?
Furthermore, I'm under the impression that the "system" will see a Raid 0 array as one drive letter, so I assume this means that we could Ghost an image of the "drive", i.e. the Raid 0 array, just like we do now with their single-hard-drive XP system. But if we ever had to restore an image, is that even possible? Would Ghost--or the computer/operating system/controller--somehow know how to restore the image properly across the multiple hard drives in the array?
And if the answer is "no", you can't restore a Ghost image, then what software is out there that would let you restore an entire image onto a Raid 0 array?
I'm so confused--obviously--and would appreciate any expert help!
