Re: PrimoCache and File Based Synchronization

I will have a look at this after the weekend.

Thanks for letting us know.

Does this fix come with regular updates as well?
Which exact OS3 version are you using?
We use 2012 server R2 x64 datacenter.

Cheers

Re: dynamic ram allocation & suggestion for best cluster size

Hi guys, while I understand the basic idea behind the request for dynamic RAM cache size, there might be the problem on how its being allocated. I'd assume PrimoCache simply picks a piece of RAM in the size its set to, potentially in one piece. To make dynamic RAM cache work, you'd essentially need ...

Re: PrimoCache and File Based Synchronization

We have PrimoCache 2.4 Server running on Windows 2012 R2 x64 on a dual socket Xeon system with 96 GB RAM and 2 TByte SSD cache. Its a Intel X5650 dual hexacore system. I have not witnessed any race conditions as far as I can tell.

Re: possible to benefit from PrimoCache for both host and VM?

[..] Considerations: 1) windows performance matters more 2) windows will be insecure (so VM minimizes risk) 3) if a linux vm is running on top of windows, I need a way to prevent someone watching what I'm doing (or taking control via remote desktop), as the windows install is insecure. If a windows...

Re: possible to benefit from PrimoCache for both host and VM?

Quirken, I just re-read the original post and think I need to clarify a few things: 1. PrimoCache, Diskeeper and V-Locity are all pure Windows based products. They will not be available on Linux systems. 2. The only way to let the Linux system benefit from caching is by having the host OS running Wi...

Re: possible to benefit from PrimoCache for both host and VM?

You mean disabling ramcache due to using PrimoCache RAM L1 and SSD L2 cache?
That is what I do as well, just let Diskeeper optimize in the super low I/O transfers by combining smaller writes into bigger chunks.
Or why else would you disable ramcache?

Re: possible to benefit from PrimoCache for both host and VM?

You are welcome! I should add that V-Locity running INSIDE the VM will optimize file I/O performed by the VM and the software running within. So only an optimized I/O is requested to the physical host OS layer. Now running PrimoCache on the physical layer gives you cached read and writes. You may co...

Re: possible to benefit from PrimoCache for both host and VM?

Hi Quirken, if your host is based on Windows and you use PrimoCache on that one, every VM will benefit from the speed improvement. In fact, most VMs use drive images, which tend to be very large single files, containing the actual image of the drive content, similar to an ISO image. PrimoCache does ...

Re: PrimoCache and File Based Synchronization

Has anyone been able to confirm the issue you are running into, jussssx1? Can you elaborate on the exact behavior and how we may be able to reproduce it? Is there a thread related only to this subject (please point me to it - if there is one)? I'd love to verify and confirm this on my end, as I am p...

Re: PrimoCache Server in combination with a Intel 900P Optane card

There are couple of issues though: A) it seems that there is a windows glitch that (only happens with dual socket systems) that cause racing condition on file io. The end result is that after prolonged period of usage, windows will report IO errors from volumes cached by Supercache. I have not witn...
