Advice about storage purchase decision - DAS vs NAS vs SAN
Posted on 2014-02-08
Greetings and thanks in advance for taking the time to help us with this critical decision.
Currently we have: Windows 2008 Dell server connected by SAS cable to a MD3000 storage (DAS)
It works as a http server to server files that amounts to a total of 15TB so far.
We are running out of space quickly and need to act now.
The volume is at its maximum limit now due to the way it was formatted initially - so attaching a MD1200 to extend the storage wouldn't work (we'll not be able to extend the volume
We are evaluating if we should get the new unit to be NAS vs SAN vs DAS.
DAS seems the simplest of them all, least complex and the the one with least possibility of bad configuration.
It can support up to 8 servers connected with single cables.
So, would you recommend we switch to an ISCSI SAN, DAS or NAS?
I'll follow up with whatever details would help you give a relevant advice to our specific case.
