Network Direct Attached Storage (NDAS) is a proprietary system, patented by Ximeta, for connecting external digital storage devices such as hard-disks, flash memory and tape drives via ethernet networks. Of interest, unlike other, more common forms of networked storage such as SAN and NAS, NDAS devices do not use TCP/IP to communicate over the network. They credit this as enabling them to achieve higher through-put rates. NDAS also supports RAID, aggregation and mirroring.

[edit] Issues

Drivers required to operate NDAS devices over a network are not currently shipped with operating systems. The devices are usually accompanied with client driver software for Windows operating systems, which is common. Drivers for Unix-like operating systems are available from the manufacturer Ximeta. Also, environments in which multiple machines wish to access the networked device or in a RAID configuration can result in data loss or corruption.
