Hi Guys

I was hoping if I outlined what I needed someone could point me in the right direction spec and possibly learning material ;)


We are currently tendering for a Building Management system installation which we have done several times before but this time the client has specified that they would like redundancy within the hard disks as they have lost historical data due to a drive failure before and are keen to move towards this not happening in the future.

They require around 2 years of historical data, rolling, which the software can do no problem. This will consume around 1tb of disk space based on they're current usage but I'd like to be able to offer them 50% more for possible future needs.

Now we come to the problem. I have a skills/knowledge defiency when it comes to things like this but I'm guessing I'd be looking at some sort of Raid arrangement that can survive a disk failure. The ability to hotswap is not required as a failed disk can be replaced in an agreed maintenance window.

Any ideas or pointers in the right direction would be much appreciated

Thanks

Lumey
 
External backups are being sorted by someone else, but will happen only weekly. I'm just trying to work out whats best for them given they're request. Tis all a bit confusing!! :)

Will raid5 and or 1 allow for the changing of a failed drive and rebuild itself?
