hello , i have the plan to setup a 40 nodes gfs cluster on EMC CX600 storage system. obviously , only few io nodes will be plug onto the san using HBA. would you mind to tell me if someone did a similar experiment, on EMC CX system ? if it's the case, do you have any ideas about the permonances level obtained for wall nodes in simultaneous read/write I/O access to a same gfs volume ? thank s David -- ----------- Dr David Allouche plate-forme Bioinformatique genopole toulouse MIA chem. de Borde Rouge BP 27 - 31326 Castanet Tolosan france : http://bioinfo.genopole-toulouse.prd.fr =================================================================== EASY and FREE access to your email anywhere: http://Mailreader.com/ ===================================================================
