hi there,
Am about to setup a PS4210x (24x 600GB 10k) and was wondering which raid type to go for. Its a single array for a smallish company (70 office staff). They use file servers, exchange, RDS via VMWare. Standard stuff really.
They need about 5TB so I could go RAID 10 but that doesn't leave much room for expansion/snapshots etc. They don't really need the extra IOPs.
I was thinking RAID 50 but a colleague tells me that's not recommended these days. I could see that its not recommended for 7.2k drives but as we're not using them I assume this will be ok?
I wasn't sure about RAID 6 due to potential rebuild times as this is the only array in the company. I hear RAID 6 rebuild times can be bad.
Be interest to hear what people think.
