Hello everyone, I'd like to dedicate 1 gigabit Ethernet interface per OST. What is the way to do this? My OST's are fairly slow (raid 10, 4 sata drives ea) by enterprise standards but still can sustain 80-90MByte/second on large sequential reads. I imagine if I striped a file over 3 OST's I would hit speed limitations using GigE.
What I'd like to do is have multiple gige nics connected to a (dumb) switch to start with. I'd put each gige nic in a separate /28. My first OSS box has 3 OST's (12 drives) and 3 gig-e nics. My MDS/MGS has a single gige nic. I have assigned 3 ip's (on different /28's) in linux to the gig-e interface on the mds/mgs box, and 1 ip (also on different /28's) to each interface on the oss server. The client (only 1 to start) is also going to have 3 gige nics, with 1 ip on each subnet. First off, what does modules.conf look like on the mgs/mds? Should it be something like: Options lnet networks=tcp0(eth0),tcp1(eth0:0),tcp2(eth0:1) Should the modules.conf on the oss/clients be something like: Options lnet networks=tcp0(eth0),tcp1(eth1),tcp2(eth2)? Can I then format each ost with the mgs/mds parameter pointing to tcp0, tcp1, or tcp2 to force it to use a specific gige interface? I have been reading through the Lustre 1.6 operations manual but have not gained a clear understanding of exactly how to set this up so it works properly. I am running Lustre 1.6.5.1 on centos 5.1 with the rpm's provided by the Sun website.
