We've acquired a Dell Poweredge 1900 which currently has a SAS 5/IR RAID controller card, this will only do RAID 0 and RAID 1, i need a cost effective way of upgrading this.

What i wish to achieve is to have 2 disks as a RAID 1 and then 3 disks as a RAID 5, Dell have not been very forthcoming in finding what i would need.

This is for internal use and we are a small business so this really does need to be low cost.

Thanks in advance.

Dell Support should have been able to give you a very quick and decisive answer.  The 1900 fully supports the PERC 5/i and the PERC 6/i adapters.

You would have thought so, however they seem to be making things sound difficult. I've not really got a background of Dell servers so do just need a quick answer on what would best fit our requirements.

You aren't going to be able to migrate directly from a SAS 5 to a PERC (if we are talking about a bootable volume), but as far as upgrading the system and doing a backup/restore, the PERC's are perfectly supported.

To be honest we're going to wipe the machine and start over as there's nothing on there that we need.

Ok so it looks like i just need either a PERC 5/i or a PERC 6/i adapter.

Further to this i currently have 2 x seagate 9CA158-302 disks ( Un-RAIDed), if i purchase a third am i right in thinking i can create a RAID 5 with it, there's no restriction on the type of disks that can be used?

Yes, you can create RAID 5 on a PERC with a third disk installed.  

While there is no specific restrictions on which drives you can use, common sense would dictate you use enterprise-class drives (not cheap/consumer drives), and the most reliable/best performance will come from using "certified" drives (Dell co-branded, for servers).
