Does anyone have any experiences with Cassandra on iSCSI? I'm currently testing a (soon-to-be) production server using both local raid-5 and iSCSI disks. Our hosting provider is pushing us hard towards the iSCSI disks because it is easier for them to run (and to meet our needs for increasing disk capacity overtime).
I'm worried that iSCSI is a non-scalable solution for an otherwise scalable application (all cassandra nodes will have separate partitions to the one iSCSI). To go with raid-5 disks our hosting provider requires proof that iSCSI won't work. I tried various things (eg `nodetool cleanup` on 12Gb load giving 5k IOPS) but iSCSI seems to keep up to the performance of the local raid-5 disks... Should i be worried about using iSCSI? Are there better tests i should be running? ~mck -- "The turtle only makes progress when it's neck is stuck out" Rollo May | http://semb.wever.org | http://sesat.no | http://finn.no | Java XSS Filter
