A 10+-minute video featuring Art Licht, Director, Oracle Enterprise Solutions Group, presents a demonstration of Oracle's Sun ZFS Storage Appliance's Analytics with VMware. Licht contends that the Storage Appliance's DTrace Analytics provides unique insights into the VMware environment.
In the demo Licht employs a Sun ZFS Storage Appliance's NFS share presented to an ESX server with multiple Windows environments running in VMs, each of which is doing a different workload and each having its own E:-drive raw disks. He begins the analytics portion of the demo with a look at NFS operations involving over 10K reads, drilling down by client, into each of them to determine sources. He looks into the operations of each of his three VMs, illustrating his findings with dynamic screenshots.
This analysis reveals very different IO reads in the three VMs and provides as well information on the level of service being returned to the VMs and operations per second, showing good performance for a random workload, he asserts. The key to this kind of performance, he contends, demands large caches with large (Infiniband) pipes. The fine grain observations delivered by DTrace enables users to employ more VMs in a single storage system with a good understanding of the operations within each one.
