Change VM size but E8ds_v5 not available

Question

Hello everyone!

I have a virtual machine with size Standard F8s v2 (8 vCPU / 16Gb)

I want to change it to E8ds_v5 but when I try I can only view E8ds_v4

I didn't find if it's normal that E8ds_v5 is not available? If I try to create a new VM I can chose E8ds_v5 without problem.

There are a important performance difference between E8ds_v4 and E8ds_v5 sizes?

Thanks a lot for your replys

Hi @Oscar Moyano ,

The E8ds_v5 and E8ds_v4 VM sizes fall into the Memory Optimized category, which offers a high memory-to-CPU ratio. For this reason, they are the best choice when it comes to database servers. Both are the same except for the higher number of IOPS the E8ds_v5 has compared to E8ds_v4.

About the E8ds_v5 VM size, that wasn't available to change the size sounds very odd because you were able to create a VM with the same size from scratch. Could you please give more details? Any error or informational message?

Hi @George Chrysovalantis Grammatikos thanks for your reply.

I don't have error message when I try to change the size of the existant VM (I tried to power off but same list of ressources). I can view:

But when I try to create a new VM I can view the correct size:

Maybe it's no possible to change size Standard_F8s_v2 to Standard_E8ds_v5. But I think that v4 size it's a good choice for my sql server.

Thanks
