Citrix MCS with Citrix Hypervisor


Julien DESTOMBES1709158802

Question

Hi all,

 

I use MCS for years with VMWare but I am new with MCS with Citrix Hypervisor.

 

Today my customer told me that the storage was full. I analyzed the storage and this that each VM have a clone of the base disk, the identity disk and the differential disk.

 

That's means that I used two more space than with VMWare ?  With VMWare the based disk is shared by all VM and not clone for each.

 

Is it a normal behavior or is there an option I missed ?

 

Thanks for helping me  

 

Regards

Hi Julien,

 

Does this host have local storage or SAN storage?

In case of local storage, XenServer does not support thin provisioning and I think this may be the problem.

Hi Silvio,

 

XenServer does support Thin Provisioning with local storage.

https://docs.citrix.com/en-us/citrix-hypervisor/storage/format.html#local-ext3ext4

But the default is LVM which isn't Thin Provisioned.

 

Hi Julien,

 

Yes you are correct, every VM has it's own base disk.

I think you need to enable Thin Provisioning to solve your storage problem.
