L2 Primocache needed for .vhdx virtual drive hosted on another (already-cached) drive?
Posted: Tue Jan 11, 2022 7:09 pm
I have an SSD providing L2 cache for my MS Storage Spaces array (drive F: formatted ReFS).
On this array (drive F:) I also have a .vhdx virtual drive mounted as drive G: and formatted NTFS. I require this for apps that don't support ReFS, such as OneDrive and Windows Image Backup.
My question is, if Primocache is already caching the Storage Spaces array on drive F:, does it also automatically cache drive G: which is actually a .vhdx file on F:? I understand Primocache works by inserting itself into the disk driver chain, so I'm not sure if Windows' mechanism to mount virtual drives will allow Primocache to cache the virtual drive automatically, or if perhaps that mechanism is below the level of Primocache in the chain.
If NOT, would I benefit from explicitly configuring Primocache to cache drive G: as well?
Thanks, any info would be appreciated!
