<html> <body> Hi, Im trying (software based) iSCSI right now, could post my benchmarks if other people are interested. Best regards, Sander At 00:00 1-5-2006, you wrote: <blockquote type=cite class=cite cite="">Sander, It depends, if you are looking for performance, definately SAN. iSCSI might have a better performance over GNBD. I found this on google <a href="http://www.bwbug.org/docs/RedHat-GNBD-Ethernet-SAN.pdf"> http://www.bwbug.org/docs/RedHat-GNBD-Ethernet-SAN.pdf</a> It has some detais about GFS on SAN and on GNBD, It might help though.3 Good Luck and keep us posted.

The results were very sad. One of the nodes <dd>(p3 1ghz, 512 mb) could run +/- 2400 insert queries per second when <dd>running mysqld-max 5.0.20 on a local ext3 filesystem. With a 2 node <dd>GFS over GNBD setup and inserts on both nodes at the same time, we <dd>only could do 80 inserts per second. I'm very interested in the <dd>perfomance others got in a similar setup. Would the performance <dd>increase when we use software based iscsi instead of gnbd? <dd>Or should we simply buy SAN equipment? Does anyone have statistics to <dd>compare a standalone mysql setup to a small gfs cluster using a san? <dd>With best regards, <dd>Sander van Beek <dd>--------------------------------------- <dd>Ing.
