Re: More Detections

If a network disk is mounted using iSCSI, it will be fully supported. Primocache works at the cluster/block level, so probably couldn't ever support a non-iSCSI disk. The way around that is to buy and install a copy of Primocache on the target network computer that serves the network disk to others,...

Re: L2 SSD Raid-0 Cache

Support indicates no on network drives, but if you mount a network drive as a local iSCSI drive it should use block-level access, and -might- show up as cacheable by Primocache. I haven't personally tried it, but if you have a spare drive you can make available via iSCSI, it's worth a try.

Re: L2 SSD Raid-0 Cache

I have another question. What do you think is a good investment for me. 1. 1x 1TB NVMe and replace 2x128GB SSD 2. 64GB RAM for L1 cache or 3. New Raid controller and combine with 2x128GB SSD L2 Cache Well, as I said before, larger cache size, better performance. If you have enough budget, I think t...

Re: Help in Plex media server

I found that with large files and a lot of turnover (frequently loading different large files), the cache was FAR better to place on the C: volume (where the Plex database and loose-leaf files like thumbs) were held. Caching the Plex media volume itself gave very low hitrates, since I was constantly...

Re: Certain keys of the keyboard don’t work after installing v3.2.0

You may also want to run a full anti-virus, rootkit, bootkit scan. Primocache installs at the kernel level, and anything looking to "tag along" by infecting it at that level may produce serious issues for the machine when that happens.

Re: L1 Cache greater than 32 GB

https://forum.romexsoftware.com/en-us/viewtopic.php?t=4143 The L1 size limitation is actually 1.5 TB. The 32 GB size in the dropdown list is merely there for convenience - you can enter in whatever value you need to use, and it will reserve that from available RAM. I just tested on a L1 cache task ...

Re: Suitability in a VM storage environment, L2 Write Cache ?'s

Primocache works at the block level. Whatever block size you setup, it will fetch from the volume (no matter what cluster size is set). It is recommended to keep block size and cluster size either equal, or to use a slightly larger block size (to reduce overhead). The write cache is definitely usefu...

Re: Risk of Data Loss with Defer-Write on SSD cache?

The easy way to avoid this currently is to have a UPS unit on the machine using deferred writes. There are still cases of ungraceful shutdown (though rare), but for power loss situations, you can avoid them with the additional hardware.

Re: [2019-12-31] PrimoCache 3.2.0 and 4.0.0 alpha released!

what is the biggest supported L2 cache size in 4.x? We had that 2 TByte limit in the past, and now I see plenty of excessively large U.2 SSDs pop up on ebay, which would do perfectly for large scale L2 caches for very large RAID volumes. Many of those U.2 SSDs are 7.68 TByte in size, so it would be...
