My file server / NAS which everything rides on from raw file access to VMs uses md raid, I currently have a 4-disk raid 10 with 3TB drives (Toshiba/Hitachi), and a 8-disk raid 10 (WD reds) and there's a 10-disk raid 5 but it's only for backups as I moved stuff off it.
I find I often get lag/performance issues where the load average goes as high as 10 or even higher at times. During these times the system is practically unresponsive and then everything on my network takes a hit. This is especially true during backup jobs or other operations.
I'm looking at increasing performance, just wondering, would I be better off just making a larger raid 10? Or am I actually better off splitting stuff up in smaller luns? I am thinking of retiring the raid 5 array and that will give me about 9 extra bays that I can put bigger drives in to do one or more raid 10's or expand existing raid 10's.
What's the better route to go for better performance?
I'm also considering ZFS on Linux, would I get better performance than md raid with that?
