[gpfsug-discuss] Use of commodity HDs on large GPFS client base clusters?

[Jaime Pinto]

I'd like to hear about performance consideration from sites that may  
be using "non-IBM sanctioned" storage hardware or appliance, such as  
DDN, GSS, ESS (we have all of these).

For instance, how could that compare with ESS, which I understand has  
some sort of "dispersed parity" feature, that substantially diminishes  
rebuilt time in case of HD failures.

I'm particularly interested on HPC sites with 5000+ clients mounting  
such commodity NSD's+HD's setup.

Thanks
Jaime
