Defragmentation and SAN

[Chiefcrowe]

I don't know if this belongs here but i was wondering, is there any benefit (or harm), in defragmenting windows volumes that are hosted on a SAN?

Defray in general is mostly pointless. It should be even more pointless when you don't even know if the blocks presented are even physically contiguous.

I wouldn't try to defrag on any sort of san or raid array assuming you are striping in some way. Just let the controller do its thing.

There wouldn't be any harm...but I don't think there'd be any benefit either.

Well defragging will move the data around the hard drive to organize it so then the raid will do the same to keep the data synced so its will put a lot of unnecessary strain on the system reading and writing files and has the potential to crash a hard drive if there's a power failure and no UPS is attached.
