I'm using glusterFs 3.03 My server is running in Heavy load, so result of your command (iozone) may by not exactly But I think there are problem with IO of my system, like that: My server store many big file, for example 10000 file, each file 100MB, so all is 10TB. I user 12HDD SATAII , 2TB, RAID6, so enough to store files. And problem: - when 200 user download concurrent (normal work), Webserver must open atleast 200 file (100mbyte/file). Then there are 200 process open 200 file concurrently. (With Gigabit nic, each user can reach 1Gbit /200 = 125MByte/200 ~600Kbyte/s, it's a normal rate!) Total IO to RAID will be ~ 1GBit <=> 125MByte/s. With single file access, my RAID work well with this rate. But, with 200 concurrent read to RAID, I see, it can not reach 125MB/s (1 Gbit) --> Result: With Not GluterFS, my server can not service 1Gbit/s access, then with GlusterFS, the rate is slower? So, What solution to resolve my hardware problem? and this solution is still good for GlusterFS? I see this: http://ftp.zresearch.com/pub/gluster/glusterfs/talks/Z/GlusterFS.pdf I see 13GBit/s can be reached, but 64 client load with single file, so it's simple to reach that rate?
