Hi Mike,<br> Jumbo frames does help for GlusterFS too. Because it reduces the latency in Gig/E connections by a margin. <br><br>It doesn't need any changes in GlusterFS setting.<br><br>Regards,<br>Amar<br><br><div class="gmail_quote">

<div>Hi everyone,<br>I am currently converting my AoE/GFS setup over to GlusterFS. So far I have been very impressed with Gluster and am loving it's ease of use. I wrestled with GFS for days, and still do too much IMO. ;)<br>
<br>I had a question about TCP/IP settings. I know Infiniband as interconnects would give us the best performance, but we currently do not have the budget to upgrade everything, so I am going to use a dedicated Gig switch along with a dedicated nic on each machine to access the Gluster cluster. With AoE, we were using jumbo frames on the switch and had each machine's MTU setting at 9000. I think by default most network cards put the MTU at 1500 or so.<br>
<br>With GlusterFS is it more advantageous to use a higher MTU setting and/or jumbo frames? For some background we are using Gluster in a webserver environment and I would say the majority of use on the file system is reads and writes of smaller files < 100K. I am not sure if this makes a difference as far as the settings though.<br>
<br>Thanks,<br>Mike<br><br><br></div><br>_______________________________________________<br>
