Re: Is caching an iscsi drive good idea?

Also it is possible to make periodic snapshots of the ISCSI virtual drive. If I go back to an older one, will primocache detect it and automatically reset the cache? As others have eluded to: any writes made to the iSCSI drive while Windows isn't active will invalidate the entire cache. So if you r...

Re: Resizable windows

To overcome this problem, the main program window should always be left in the foreground or minimized in the tray area of the taskbar but this is not a real solution. You are right, it isn't a real solution. But then, asking a developer to continue to support small non-essential changes to a progr...

Re: Is there any way to force L2 cache a specific directory?

Or.... just install the latest 7-zip and use the context menu entry marked "CRC SHA" and use the '*' option. It will perform a series of tests on the folder, files in it, and all subfolders which forces a read on the entire set of data. I do this and it manages to ask Windows to access all...

Re: how to configure?

Nope, they can be totally different sizes. But I -would- recommend matching their block size in the Cache Tasks you setup.

Re: how to configure?

Janus is correct - USB "sticks" are unreliable, and can fail at a much higher rate than true external SSD drives. If you want to use a SSD as a L2, make sure it is on a USB 3.x port, and is in a controller which supports high speed connections. I personally would never use either a "s...

Re: PrimoCache Settings

Since you have 64GB of physical system RAM, you can use a smaller "block size" in Primocache if you want to. Smaller blocks usually give greater speeds at the cost of using more system RAM. I have a similar setup - 64GB of RAM, and I am using a Cache Task in Primocache with a block size of...

Re: SSD caching with striping possible ?

If the drives (group of striped target disks) are recognized by the OS at boot time, they can be used by Primocache as a cache volume without problems. Plenty of people have used RAID 0 for example to combine SSDs into a larger L2 target. I'm not sure if you are using an actual RAID architecture, wh...

Re: Looking for some pointers/feedback for current setup

-4x 3TB 3.5 spinners in hardware raid 5 - formated as 1 ntfs volume and contains my music libraries and plugins This is going to be a problem to cache with any decent amount of hitrate, given the total volume size of 9 TB in RAID 5. To do the job you're going to need at minimum, a 1TB fast SSD or N...

Re: L2 cache verification

@Jaga - i partly agree. I agree data integrity should be 1st. This is why using L2 for defer writes can be still safe. Take bcache as an example. It did it right. On the other hand - we also talked here about L2 read cache, and how crash handles that. Saying that L2 'resets' (I know it's wrong word...
