Zmotion
Find out how the Zmotion process works
Last updated 13th July 2020
Objective
OVHcloud Zmotion is a technology that transfers data across a customer private network between two physical storage arrays.
Instructions
Description
Our datastores run NFS on ZFS in a home storage array called Leclerc. In order to gain greater flexibility in the management of our hardware, we have developed a way to hot-migrate the stock of ZFS data from one hardware device to another.
This is called "Zmotion" (for "ZFS motion").
The goal of Zmotion is to free a datastore without any vCenter action necessary (no vMotion, no cloning...) and without any action from the customer's side.
Steps in detail
- A free datastore, on another Leclerc, is reserved in our data centre to push all the data.
- Our network properties are set on the destination datastore.
- Data transfer begins in a private network dedicated to the client.
- When all data is transferred, the NFS service moves from one table to another.
From VMware's perspective, there is no downtime.
