The problem is that using an mlc-based SSD as a ZIL causes them to wear out and fail quite quickly. Speed up your workflow by adding internal caching SSDs. ZFS is designed to make effective use of RAM and solid state drives for caching. SSD cache So I have an extra 120GB Intel SSD that I want to put in my updated Nas build. ZFS volumes are recommended to get the most out of your FreeNAS® system. SSD cache can improve the performance of random access by storing frequently accessed data on the SSD cache. I can probably say that using Gitlab is a bit snappier through the web interface after implementing the SSD cache. You still need a server with 12 SATA ports, 12 drive bays, and a ton of RAM. If you can satisfy your read cache requirements with RAM, you’ll enjoy better performance than if you use SSD read cache. I was wondering if anyone knew how to do this. As it is possible to use more devices, like it’s shown in "Create a new pool with RAID*". SSD cache devices only help if your working set is larger than system RAM, but small enough that a significant percentage of it will fit on the SSD. 0網段 對 Freenas 用. Here are the steps I took to migrate my Home Lab GEN II with FreeNAS to Home Lab GEN III with VSAN. 40 GHz: 20 MB Intel® Smart Cache: Intel® Xeon® Processor E5-2640 v3 : Launched: Q3'14: 8: 3. Other options are to force all writes to the pool to be async in the ZFS properties (generally a bad idea).
