<DIV>Hi Amar,</DIV>
<DIV> here is my benchmark, pls help me to <SPAN
class=keyword>evaluate it.</SPAN></DIV>
<DIV> 1. [Env - Storage servers]</DIV>
<DIV> Gluster version: 3.3 beta3</DIV>
<DIV> OS : CentOS 6.1</DIV>
<DIV> 2* Server : CPU
:
E5506 @ 2.13GHz 4*core</DIV>
<DIV>
MEM: 16G</DIV>
<DIV>
Disk : 1T * 12</DIV>
<DIV> Net:
bond0 = 4 * 1Gb</DIV>
<DIV> 2. [Env - Testing clients]</DIV>
<DIV> OS: CentOS 6.1</DIV>
<DIV> 6* Server:
CPU:
5150 @ 2.66GHz </DIV>
<DIV> MEM:
8G</DIV>
<DIV>
Disk: RAID0 =
1T * 3 </DIV>
<DIV>
Net:
bond0 = 2 * 1Gb</DIV>
<DIV> 3. [Env - Switch]</DIV>
<DIV> 1 * H3C Switch</DIV>
<DIV> 4. [Env - Testing Tools]</DIV>
<DIV> iozone for cluster, clients is rsh
cluster.</DIV>
<DIV> 5. Volume info </DIV>
<DIV> Type: distributed - stripe</DIV>
<DIV> bricks: 6 * 4 = 24</DIV>
<DIV> 6. Iozone command: </DIV>
<DIV>
./iozone -r 1m -s 50g -t 25 -i 0 -i 1 -+m /CZFS/client_list -R -b report.xls -c -C -+k -e
</DIV>
<DIV> </DIV>
<DIV> then my benchmark is :</DIV>
<DIV>
<DIV>
" Initial write " 424258.41 KB</DIV>
<DIV> </DIV>
<DIV>
" Rewrite " 458250.97 KB</DIV>
<DIV> </DIV>
<DIV>
" Read " 671079.30 KB</DIV>
<DIV> </DIV>
<DIV>
" Re-read " 797509.20
KB</DIV></DIV>
<DIV> </DIV>
<DIV> here I have 4 Questions:</DIV>
<DIV> Q1: Why the Read is better than write, is
ok?</DIV>
<DIV> Q2: Refer to experience, This benchmark is best ,
good or bad? </DIV>
<DIV> Q3: How to optimize the gluster to impove the
benchmark?</DIV>
<DIV> Q4: How can I get other friends' benchmark,
which I use to compared?</DIV>
<DIV> </DIV>
<DIV> Tks very much.</DIV>
<DIV> </DIV>
