With OST servers it is possible to have a load-balanced active/active configuration. Each node is the primary node for a group of OSTs, and the failover node for other
...
Anyone done this on a production system?
we have a number of HP's Lustre (SFS) clusters, which use dual-homed disk arrays, but in active/passive configuration.
it works reasonably well.
Experiances? Comments?
active/active seems strange to me - it implies that the bottleneck is the OSS (OST server), rather than the disk itself. and a/a means each OSS has to do more locking for the shared disk, which would seem to make the problem worse... _______________________________________________ Beowulf mailing list, Beowulf@beowulf.org To change your subscription (digest mode or unsubscribe) visit http://www.beowulf.org/mailman/listinfo/beowulf
