If you have had a chance to play around with our prerelease bits you might be wondering what all the types of storage are. You might also be wondering how to decide which storage is right for your virtual machine (VM). One question I'll address in a future blog posting is storage performance. Its a little early to talk performance with prerelease bits but rest assured we are working hard to drive much better performance.
So what type of storage is there?
There is also another dimension to consider
An overview of pros and cons…
Don’t have to decide the size of the disk upfront
Not as performant as Fixed VHD
Best performance for file based hard drives
Great for deployment of base golden image
Read might have to access delta and fixed drive + more file overhead.
Attach a physical drive / LUN to a VM
Does not support Virtual Machine Snapshots + no easy as easy to move as a VHD. This is great for direct attached storage however.
Tricky configuration. You have to take the drive offline in the root partition before it can be configured to a VM. Use Disk Manager (diskmgmt.msc), diskpart.exe, …
So which storage is best for you? You’ll like this answer – It depends J
We expect Fixed VHD and Pass-through to be the most common in deployment because of their predictable nature.
