Re: L2 Cache reset/wiped out after a chkdsk on C drive

Support might have to answer that. You'd think it wouldn't reset L2 if D: wasn't also checked.

I assume "Volatile cache contents" isn't checked on the advanced options page of your L2 config for that cache task.

Re: L2 Cache reset/wiped out after a chkdsk on C drive

If the contents of a cached drive change prior to PrimoCache loading it's drivers, then the cache is marked as dirty and flushed.

Re: Ramdisk disappears upon reboot

In order to have the Ram Disk mount at boot time, you have to associate it with a .vdf file which holds the disk contents. It's in the Disk Configuration area under "Backing Image". You'll want to have Primo Ram Disk save the image at shutdown so it will mount with the same contents (Image...

Re: Primocache for diskless program (ccboot)

Nope, though it's been requested in the past. For now all you can do is pre-load it yourself from a client, 2-3 times. That should force the cache to prioritize it over other stuff short term. The problem you're seeing so far is that the games are large, probably don't completely fit into L1, and th...

Re: write cache as read cache

You'll only get premature wear on the SSD if you write/re-write to it while it's very full (>80%) and you don't have overprovisioning enabled (if your SSD supports it). Keep it under 75%, make sure TRIM runs regularly, and it's not much additional wear. Higher endurance SSDs (like the Samsung Pros) ...

Re: write cache as read cache

There's always a risk when enabling write caching. If you don't use a UPS to protect against power outages, or if you get the occasional BSOD on the machine, then you risk losing data. If however your computer is extremely solid, and you have a UPS protecting it, then you can use L2 write caching to...

Re: Primocache for diskless program (ccboot)

266GB L1+L2 to cache 10TB means you're effectively covering 2.6% of the disk, but how full is it? Divide 266 by the number of gigs of data you have to find real coverage percentage. If it turns out not to be fast enough most of the time, you might have to double the size of the L2 drive (or just rep...

Re: Memory Integrity compatibility

Memory Integrity protection can cause problems with some device drivers or other low-level Windows applications, which is why it’s disabled by default on upgrades. Microsoft is still pushing developers and device manufacturers to make their drivers and software compatible, which is why it’s enabled...

Re: Deferred Writes - Power Loss + this is awesome.

In conclusion, let me tell you that I am looking forward for functionality that will allow restoring data from Level 2 cache after an unclean shutdown, as that could not only massively improve my disk write performance, but also keep the noisy HDD off for most of the time. Verify-after-write and Ve...
