<br>Hello!<br><br>I am new to the list, but I have been researching Lustre for quite some time and finally have an occasion to use it. I am trying to do some capacity planning and I am wondering if there are some general rules of thumb for configuring a Lustre environment.<br>
<br>Specifically:<br><br>A> If increasing the number of OSTs increases throughput, is there a relationship that can be used to determine how many OSTs we're likely to need at the outset to establish a baseline minimum throughput. For examples, if I want to get 3GB sustained throughput how many OSTs will facilitate this.<br>
<br>B> Does the MGS and MDS have to be separate for best performance, or can they be consolidated into one server without causing too much hardship<br><br>C> Right now I am looking at a model where I am connecting all the OSTs, and the MDS/MGS together using infiniband, and connecting the storage via fibrechannel. Is this the ideal solution or am I going in the wrong direction. <br>
<br>D> Just wondering what clustering software people use on the front end with Lustre typically, if they are going to be using this as a filesystem for some kind of HPC environment, what is the most popular clustering technology for this.<br>
<br>E> Does Heartbeat install next to whatever HPC clustering technology you have?<br><br>Thanks, and I hope that I can soon be someone who contributes rather than just asking questions :)<br><br>--Mark T.<br><br>
