Freezes with Dual CPU (2 Numa) Architecture
Posted: Thu Nov 28, 2019 4:29 pm
I'm VERY new to this forum. I purchased the PrimoCache about a month ago based on some research. It is definitely something I need in my setup. Thank you for making this product.
However, I believe there may be a stability issue in my particular configuration. I am running a dual processor xeon 2690 (sandy bridge) setup. I have a total of 16 cores / 32 threads with 8 cores per xeon. This setup also has a total of 128 GB of ram, a ssd (sata) boot drive, a 4 TB spinning disk (sata), and a 480 GB NVME drive (pcie).
I setup PrimoCache with 2 layers of caching, the first layer being 32 GB of RAM, the second layer being the 480 GB NVME drive. I set it up to cache both the SSD boot drive as well as the 4 TB spinning disk. I set it up to do write-through so as to be stable (no caching of writes).
I am experiencing random lockups where the screen 'freezes', and there's no response to any sort of input. These freezes occur for a second to a few seconds, but then will occur where the only recourse is to hard reset the entire system.
These freezes will happen from 10's of minutes to a few hours. Usually withing 3 to 4 hours, I can be guaranteed that the system will freeze and require a reset.
I have eliminated all other possibilities of lockups - i.e. bad power supply, bad ram, bad processor, bad video card etc... The only thing that gets rid of the freeze behavior is to remove the drive caching.
I am wondering if it's my 2 processor setup that may not be something that many other (or any other) users would have used before that may be causing the freezes.
I'm hoping there is some way we can debug or troubleshoot this, because I really like the performance benefits that this tool would give me. I am a professional software developer, so if there's some way I can help you to troubleshoot this issue, please let me know. I have the visual studio toolset, so could try to debug if you wanted me to help you with that.
Thanks,
Steve
