I have been asked to provide a new fileserver to store our medical images (raw format, not dicom). As we have no IT staff, I have to find a solution, and I hardly know anything about this topic.
The requirements we have are: scalable to 24 TB in 3 years, windows file sharing and the share has to be as big as possible (1x24TB share). First thing I found is the NETGEAR ReadyNAS 3200. Seems like a very good system, accompanied by a big community, which could come in handy if we run into trouble.
But how scalable is this system? Everywhere I'm told that this system is 'not stackable'. I don't know how stacking NAS' work, but maybe we could buy an iSCSI initiator, configure all NAS' as iSCSI targets, then build a raid on the initiator covering all targets, then share this big raid as one windows share? Or can't this be done? I'm clearly at a loss on how scalability works, so if anyone could explain this, I'd be very grateful.
If anyone sees another solution (like another NAS comparable to the readynas'specs but stackable), you can suggest this too of course.
