My unRAID box is a refurb Dell R710 with 48GB of RAM and 2 hexcore CPUs (max of 288GB of RAM). That said, I usually don't need around half the RAM even with a few VMs spun up.

 

I'd like to be able to allocate that as cache rather than as VM memory if at all possible. It'd be great if the cache could be disabled and enabled (or even resized) in the GUI to allow all the VMs to be booted up or re-allocated as needed and put the rest of the RAM to use as cache. It could even count as a storage device toward the limit, I wouldn't mind, it'd be worth it for the flexibility.

 

Thanks for the consideration,

Half of 48 is only 24. Not large enough to be very useful as a cache drive I wouldn't think.

 

This sounds like a feature request though you didn't post it in that subforum. I doubt very much you will get much interest in this.

The feature is already implemented... in Linux by default - "unused" RAM is already automatically used as 1st level cache.

You know, I suppose linux will use the RAM as cache, which is probably fine. I was hoping something that would be controllable on a per share or directory basis, but the linux cache management will probably do just fine.

 

Consider this closed, especially since a plugin in dynamix does more or less this, although not with the highest level of integration.
