Virtual NAS Head: Turn Storage/RAID stack into NAS (w/ NAS)




Summary

1. Goal: Turn original Storage/RAID System into a NAS with NAS Head.

2. Three Solutions (A/B/C):

(A) Install a middle layer "Physical NAS head" to serve NAS clients.
(B) Install a middle layer "Virtual NAS Head" within the Storage/RAID box.
(C) Integrate Storage/RAID stack with NAS Stack Protocols. (No VM)


Solution A: Real NAS Head --> Original Storage System



"Total 3 Boxes"

代碼:

Client
{
   => Box #0
}

NAS
{
   => Box #1 (NAS Stack/Protocols)
}

Original Storage/RAID System
{
   => Box #2 (iSCSI/FC/RAID Stack/Protocols)
}







Solution B: Virtual Read NAS Head --> Original Storage System



"Total 2 Boxes"

代碼:

Client --> Virtual NAS Head --> Original Storage System

Client
{
   => Box #0
}

Original Storage System
{
    => Box #1  (iSCSI/FC/RAID Stack/Protocols)

    Virtual NAS Head
    {
       => Box #1.1 Virtual (NAS Stack/Protocols)
    }
}



Solution C: iginal Storage/RAID System with NAS Stack + Protocols



"Total 2 Boxes"

代碼:

Client --> Storage/RAID System with NAS Stack + Protocols

Client
{
   => Box #0
}

Original Storage System
{
    => Box #1  (iSCSI/FC/RAID Stack/Protocols + NAS Stack/Protocols)

    (Note: NO VIRTUAL Machine)
}
