[Gluster-users] How about quality of GluterFS?

[Tejas N. Bhise]

Please let us know how many glusterfs servers and glusterfs clients you are using. The glusterfs clients would typically be the application server/webserver in this case. Are you putting glusterfs server, glusterfs client and webserver all on same server with 24TB ? what kind of CPU and RAM do you have ? What is the existing throughput you are getting ( your just mention you are not able to reach 125 MBps. 

Do let us know more.

Regards,
Tejas.

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?

Thank very much for your helps!
