With regard to NAS devices, I just talked to a DD engineer who discussed the business strategy from the HD manufacturer point of view. I have also recently studied the available NAS devices, which vary from <100GB to the enterprise level terabyte systems.

I have questions about the LAN interface. Most of these devices claim that you can plug it in to your LAN and any protocol (ethernet, GE, FDDI, etc) you are using will get stored on the disks. This is given as one of the cost advantages of NAS as opposed to a SAN - using only one NIC instead of several.

My question is - doesn't this involve a processor between the NIC and the disks to convert the incoming LAN protocol to FC or SCSI for writing to the disks? I find very few details on this process, but if accurate it would seem to lead to some disadvantages.
