I am missing out on SC17 this year because of some instability with our 2 ESS storage arrays. We have just recently upgraded our ESS to 5.2 and we have a question about verbRdmaSend setting.
Per IBM and GPFS guidelines for a large cluster, we have this setting off on all compute nodes. We were able to turn it off on ESS 1 (IO1 and IO2). However, IBM was unable to turn it off on ESS 2 (IO3 and IO4). ESS 1 has following filesystem: projects (1PB) ESS 2 has following filesystems: home and hpc All our client nodes have this setting off. So the question is, should we push through and get it disabled on IO3 and IO4 so that we are consistent across the environment? I assume the answer is yes. But I would also like to know what the impact is of leaving it enabled on IO3 and IO4. Thank you. Damir
