Re: Caching both SSD and spinning disk

I just realized I can't set separate block size if they are both in the same cache task. I used to have 4k for SSD and 16k for HDD. Now 4k gives 1.5GB overhead :(

Re: How is write cache implemented

I agree, but there should be an option to turn it on or off in configuration. SSDs won't like it much

Re: Freeze problems when using primocache

yes, the freeze happened when there was no L2 for the SSD. Actually I added it after the last freeze and since then I didn't have any freeze. The idea of L2 cache for ssd is to preserve cache between boots. I'm probably not going to leave it like that, but that's not what's causing the freezes. And ...

Re: Caching both SSD and spinning disk

Well that's very good! It doesn't solves the problem with a second ssd (for example if L2 is on different ssd), but it's good for now. Anyway. Think about option 2 - it shouldn't be that hard.

Re: Questions/Feature request

PrimoCache was able to choose data to L2 cache by frequency. However, it seems that the result was not good and lots of customers complained that the speed of populating L2 data was too slow. That's why I suggested making it option in cache configuration - so everyone can choose their preferences. ...

Re: Freeze problems when using primocache

Here it is. However usually I don't have L2 cache for C: (SSD). I happened to have spare SSD for a while and I'm testing it as an L2 cache for the first SSD. Also I'm playing with the amount of L1 cache - it wasn't always like this. I'm struggling to decide if I want to buy PrimoCache. As you see I ...

Re: Ramdisk - allow multilevel folders creation

Yes, but I would like to have persistent hybrid disk. I tried the image with load only - works fine. I even compressed the image - it's 600kb for 4 GB ram disk. But I need hybrid disk with persistent contents. The workaround as a start is multi-level directory creation for hybrids. Of course I would...

Ramdisk - allow multilevel folders creation

Currently only one level folders can be pre-created. Currently I use following structure:
systemp
usertemp\administrator
usertemp\user1
usertemp\user2
...etc

It would be nice to allow \ and create all folders in path

Request: Ramdisk - use hybrid disk space as a hibernation

It would be nice to store ram part of a hybrid disk to the disk park (an option). If there is no space: 1. work as it is now - drop the contents and start with a fresh new hybrid disk on boot 2. there can be an option to show available space only the amount set in disk space so there will always be ...
