Zmotion

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.
