The performance comes from the parallel version of pgsql, which uses all CPUs and I/O channels together (and not special settings of ZFS). What sets this apart from Oracle is that it's an automatic parallelism that leverages the internal storage across multiple machines, no SAN involved. Fault tolerance is also automatic and up to half of the machines can fail without downtime. Oracle's fault and parallelism model relies on SAN, which is both expensive and does not scale bandwidth with CPUs. With the Sun warehouse, scaling of CPU and storage bandwidth are coupled - just add another node with internal ZFS storage and the response time, data loading, updates, etc scale. ...
Cool. That's great stuff. I certainly wasn't aware of such advances to pgsql. I'll get my hands on greenplum and give it a spin :). -- Just me, Wire ... _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
