Using DTrace to Understand What's Happening to VMWare's VM I/O in Real-time [28106]
The Key to Good Performance: Large Caches, Large Pipes (Read Infiniband)
A 10+-minute video featuring Art Licht, Director, Oracle Enterprise Solutions Group, presents a demonstration of the analytics feature of Oracle's Sun ZFS Storage Appliance with large caches and large (Infiniband) pipes with VMware. The NFS shares are 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. DTrace shows good performance for a random workload, he asserts, because the fine grain observations delivered by DTrace enable users to employ more VMs in a single storage system with a good understanding of the operations within each one.

Disks from the Perspective of a File System [28092]
Of Necessity, a Jaundiced View
Dr. Marshall Kirk McKusicK takes a critical look at disk-based storage in terms of the shortcuts it takes and the remedies file systems must employ to overcome them. The upshot of this, the author concludes, is that file systems must be aware of the disk technology on which they are running to ensure that they can reliably deliver their promised semantics. Users need to be aware of the constraints that different disk technology places on file systems and select a technology that will not result in poor performance for the type of file-system workload being used.

ZFSBuild 2012 Due Soon [27721]
More Power than ZFSBuild 2010 at Same Price Point
ZFSBuild 2012 is being designed to deliver more CPU, much more RAM, more cache, better drives, and better chassis than its ZFSBuild 2010 at the same price point: $USD 6765. The original ZFSBuild was based on 12GB of memory. ZFSBuild 2012 starts with 64 GB using 8GB DIMMs. The motherboard has the capacity to go to 256GB with 32GB DIMMs. The team plans to evaluate Nexenta Enterprise, OpenIndiana, and revisit FreeNASs ZFS implementation running the same battery of tests used in 2010 for the original ZFSBuild 2010 benchmarks.

Oracle ZFSSA Hybrid Storage Pool Demo [26946]
How to Accelerate Performance of Oracle Storage 7000 Series
In a video running something under eight minutes, the impact of the ZFSSA hybrid storage pool on storage performance is demonstrated by Darius Zanganeh. He shows how high DRAM cache capacity and both write-optimized ssd and read-optimized ssd enable users to achieve large increases in drive performance of the Oracle 7000 Storage Series.
