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)
}
