Success

[tverweij]

System: HP385 G7, 12 core, 2 Tb Raid 10 with 8 NLSAS (7200Tpm), 128Gb Ram, P410/2Gb BB-WriteCache, Windows 2016, HyperV role with 10 VM's.
The system was almost not usable anymore - too slow (too much VM's for the disk system).

But with 32 Gb L1 Readonly cache installed (no L2 cache), and now the system performs like there are SSD drives in it.
At this moment still trial, so I will update within 60 days.

No suggestions needed in my case.

I keep telling people Primocache is good software. Glad it helped you.

Thanks!

Did several tests in different machines, and it looks like 1Gb cache per 40Gb used disk space is almost optimal in the Hyper-V scenario (cache/disk = 2.5%). More does not really help anymore, less decreases the cache hit rate.
