Re: [Tool] Automatic pause and resume for backup-software

Fantastic job. This is really what I wanted. Now that we are up to 4.10. Would it be possible to "lock" the cache. As opposed to pause. I assume the lock feature would still service reads.

Thanks for your efforts.

Re: [2018-12-30] PrimoCache 3.0.9 released!

I have used this at home for ages but seriously want to try it at work to tier our old storage. If I am able too defer write to an ssd only. Would it be possible to survive a power out without loosing the writes? You add that feature and you can ask $500 plus. Our vm pool runs fine until someone pus...

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

Thanks for the clarification, I'm so happy with the rest of the product, I can live with the risk of data loss when the storage is busy. And I can just turn of deferred data when I can.

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

But if there is power loss there is no flush, does it look at boot up in the L2 for potentially unwritten deferred blocks? Would adding this feature be something that you would consider adding in the future? Because if you did you'd have a server level feature that you could easily charge more for. ...

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

I'd just like to share some of my results. All these results were taken from inside a VM running on the cached storage. The first pic is from an refs petition running on a freenas backend. Write-back disabled and relying on the ZIL[L2 write acceleration] to speed up the writes. While it is a "f...

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

"I have to say that the results are unknown in the case of a sudden power-loss, system crash or bsod."

What does the software do o reboot? does it look in the L2 cache for unwritten deffered blocks and run them to the storage?

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

I've noticed that the SSD can get over burdened when the L2 write cache is flushing at the same time the read cache is be read. I bought another SSD so I could have a separate write cache on other SSD, mirrored of course. But alas I can't have a separate write cache disk in the configuration options...

Deferred Writes - Power Loss + this is awesome.

I would like to state that I'm not connected to or affiliated with ROMEX software, I have extensive IT experience, and generally know most of what I'm talking about. Ever since I heard of caching a few years ago I've been on a mission to improve my old spinning raid 10 performance, for 3 months I us...
