Right now I have my OS (C:\) on the SSD in a 36Gb partition, then I have 5 VMs on the same SSD in a second (D:\) partition. I only run 1, 2 at the most as needed as I need to work in different developer environments. All of the VMs are differencing disks based on 2 parent disks. I have a second spindle disk (H:\) that I am using for backups of the VMs and I have also moved the paging file there.

But I have 13.2 GB free and I since I need to add more VMs I was wondering how I should rearrange these. I am thinking since Parent disks are read only that maybe they should be moved to the spindle (H:\). But what about the Page file? Should I leave it on the spindle or would I get better performance from it being on the SSD?

The Hyper-V machine is an Intel core i7-4770 @ 3.40Ghz with 24 GB of RAM running Windows 8.1.

Thanks,

How heavily are you using the page file?  If it isn't being used much, leaving it on the spindle should be fine.  Besides, you are operating that way right now.  Are you noticing any performance issues due to paging?  If you have enough memory to run all your Windows 8.1 applications and VMs, you should not be using the page file much.

As for where to place the virtual hard disks for the VMs, that is totally dependent upon what they are doing.  Do they have high disk activity?  Then it might make sense to leave them on SSD.  The operating system itself is not likely to need to be on the SSD.  Generally it is more important to have the data on the SSD because that is where most of the IO comes into play.

Hi Sir,

How are things going ?
