Hi, I am planning to use GlusterFS for backup purposes. I write big files (>100MB) with a throughput of 2-3GB/sn. In order to gain from space we plan to use erasure coding. I have some questions for EC and brick planning: - I am planning to use 200TB XFS/ZFS RAID6 volume to hold one brick per server. Should I increase brick count? is increasing brick count also increases performance? - I plan to use 16+2 for EC. Is this a problem? Should I decrease this to 12+2 or 10+2? Or is it completely safe to use whatever we want? - I understand that EC calculation is performed on client side, I want to know if there are any benchmarks how EC affects CPU usage? For example each 100MB/sn traffic may use 1CPU core? - Is client number affect cluster performance? Is there any difference if I connect 100 clients each writing with 20-30MB/s to cluster vs 1000 clients each writing 2-3MB/s? Thank you for your time, Serkan -------------- next part -------------- An HTML attachment was scrubbed...
