February 16, 20233 yr Hi, I was wondering if it is better to have smaller specific cache pool or one big one for everything? I currently have a cache pool specifically for dockers/VMs, one for transfer/downloads and one that I use as a scratch pool. I am planning to update my server in the near future, and will end up with 4 extra slots for drive that I intend to fill with SSDs for cache. Making it a total of 8 sad dedicated to cache. So I am wondering how to configure them best Currently my cache drives are 4 x WD blue 500 GB. (2.5) 1 x crucial mx500, 500 GB (2.5) 2 x WD black, 500 GB (nvme) One the server switch happen, the crucial and 2 x WD black are gone, used for something else. I will buy 4 new sad in the 2.5 format. I have 2 options for that 8 drive cache setup. 1- Buy 4 x 1 TB. Set those 1 TB drive in a raid 10 pool and use it has a transfer / download cache. Take the other 4x 500 GB set them also as a raid 10 and use that as docker / VM cache pool. Which would give me a 2 TB cache for all my file transfer and downloads with a redundancy and 1 TB cache poll for my dockers and VMs. 2- buy 4x 500 GB ssd and set all of the 8 sad as a raid 10 cache that I would use for everything. Giving me 2 TB total cache. Is there one option better than the other? What are the plus of one versus the other? Thanks for you advices I am open to any other suggestions.
