A raid 1 consists of 2 drives only. My guess is that the website doesn't offer a "Dual raid 1" setup or something like that. Physically it can do it, but the website just won't let you select it. I would recommend a PERC H200 over the S300 (unless you think you may want raid 5 at one point), as the S-series is firmware based raid (no dedicated raid processor), whereas the H-series has a hardware processor (the 200 only supports raid 0, 1 and 10 (the 700 and 800 give raid 5, 6, etc)). You may want to call Dell sales and see if they have a way to buy this server with 2 raid 1's (with 2 160's and 2 1TB's). If not, you may have to buy it with just the 160's and buy 2 separate 1TB drives (from Dell) and make them a raid 1 yourself.
I need to get a new file server for my small office of 9 users. We're currently on a Poweredge 1800 with SBS 2003. I'm looking at the T110 II but my concern right now is not being able to get 4 drives of different sizes on a raid 1. Our current setup (raid controller) allowed me the following configuration in a raid 1: 2 - 160GB hard drives as OS C:\ 2 - 1TB hard drives as data file D:\ Now, when I first purchased the PE1800 server, it only came with the two 160 hd's, and they were partitioned into 40 and 120. Maybe 2.5 years ago I used 3rd party software to delete the initial 120 drive and expand the 40 gig into the full 160 gigs. After that I put in the two 1TB hd's, and had no problem with the raid controller set this all up as raid 1. As I'm speccing out this new file server, I can't even get the option to add 4 hard drives configured to raid 1. Is the controller capable of this? This is my big concern. I'm looking into the Raid 10 as a possible solution/workaround. I'm not really even needing the drives to be the same size. Ideally, I'd still keep our C drive as small as 250, and our D drive a 1TB, but again...not an option within the dell purchasing system. I would appreciate any help in this and my understanding of the raid options and controllers.
