VMware : VMmark studies the VMware DRS

Vroom guys/gals are busy.

A two-node DRS cluster was created for these experiments using IBM eserver 336 systems. Two modified VMmark tiles, consisting of five server VMs each (file, database, java, standby, and web servers), were used. A baseline throughput measurement was first taken to determine the optimal expected throughput (Scenario 1 in the slide). Subsequent tests were started with all workloads running on a single server within the DRS cluster (Scenario 2). The DRS scheduler was then run with both moderate and aggressive settings. The resulting VM placements are shown in Scenario 2a and Scenario 2b, respectively. The aggressive setting results in the intuitive placement of essentially splitting the tiles across the two systems except for the standby server. That the standby server does not migrate is not surprising since it is consuming few resources.

Good stuff there. Hopefully someday we could also study the RAC with VMware. But I'll hear when I'll hear ;-)

Check it out.
