In our demo enviroment, we have been lucky enough, to get a Nimble storage system wich supports VVOL
I thought i would give you a litte taste on how easy it is, to manage your VM’s storage requirements, once you have VVOL in place.
Note features etc, might be different, of other storage systems.
Lets try it out 🙂 I assume you have connected the storage system, and set it up for VVOL.
For Nimble, this was quite easy. Connect to vCenter using the management interface, and select configure VVOL.
If you are in doubt, RTFM 🙂
- Log into the vSphere Web client, and select Storage Policies.
Select Create new storage policy
- Give it a name, and a description.
As you can see in the description, we will create a policy, that snapshots every 5 minute, and keeps that snapshot for 60 minutes.
- Select next until you reach Rule-Set-1.
Select Nimblestorage (or whatever your storage provider is called) from the drop down menu, and select Protection schedule (minutely) from the new drop down, that appears below.
- Change the following values :
Start Time : 0:00
End time : 23:00
Snapshot frequency : Every 5 minute
Snapshots to retain locally : 12
This should create a snapshot every 5 minute, for the entire day, 7 days a week, and keep the last 12.
- Select Next, and see that the VVOL datastore, is compatible with your new storage profile.
- Select next and finish.
- To test it, i clone a VM, and give it the new storage profile.
I’m guessing that you know how to clone a VM. So the only thing i will show you, is the page, where you select the storage profile.
It should look something like this, with compatible storage, when you select the newly created storage profile.
- In the Nimble system, it now looks like this under Volumes.
It creates a “Lun” for each file, the VM consists of. And each of these, can have a different storage profile.
So you could easily have Snapshot protection for the Base OS, and another application specific for the VMDK files, that contain the application.
- If i select one of the files (after the first 5 minute) i can see, that a snapshot has already been taken.
So this i an easy way, of making sure that the VM disks, get the right features.
I hope you found this useful.
