March 13, 20242 yr I´m running two servers with the same user data on both. If one dies, I have the other server on hand. The first server is online 24/7, except when I mess around. The second server also serve as a game VM. Every now and then (every 2-3 Months) I rebuild the main storage on Server1 due to expanding the pool. Write speed is a priority. My goal is to achieve saturation for 2 x 10Gb port in Server1. As of today: Server1: 10 x sata 8 TB ssd raidz2 pool. Server2: 6 x sata 18 TB hdd raidz2 pool. What will be the best pool setup on server1 for max write speed over 2 x 10 Gb nic with FreeFileSync (or simalar)? Server2 have a 25Gb nic. Current speed: Happy for every feedback. //F
March 13, 20242 yr Author Some runs: Testing receiving server1 main storage (10x raidz2) write performance: About 1.3 GB/S Testing sebding sending server2 (6x raidz2) read performance: About 500 MB/s Server2 (6x hdd raidz2) write speed was about 700 MB/s. This is quite surprising to me. I thought it would be the write speed on the receiving server1 (10x raiz2)that would be the limting factor. But its the read speed of the 6x hdd raid2 on server 2. thats the most limiting factor.
