Hitachi Unified Compute Platform 6000 for Oracle Real Application Clusters on Four Nodes Using Hitachi Virtual Storage  Platform F800, Hitachi Accelerated Flash, and Hitachi Compute Blade 2500

    When I was looking at performance numbers of VSP F800 in some documents a few months back, I was skeptical.

    Once a four-node Oracle RAC 12c R1 lab environment was set up with a VSP F800 and four 520H B3 server blades on CB2500,  I was amazed by this little 5U storage array!  712K IOPS with just 1.1ms average latency for 8KB read ORION workload with less than 1% of storage read cache-hit. This box is also capable to handle >24GB/s Peakmarks’ large sequential read workload. SLOB OLTP results are incredible too. It outperforms  another vendor’s enterprise class two-controller all flash array (model name 850F) by a whopping 250% in terms of IOPS and Transactions per Second (TPS) ! !

 

   Unlike other storage vendors’ testing environments, we are using large database sizes to minimize storage read cache-hit and truly demonstrate the value of flash storage. With large storage cache and a similar size of testing data set, cache read-hit could be close to 100%!  128 x 120GB host addressable devices or a total of 19.2TB capacity for ORION,  4 x 4TB Oracle tablespaces for Peakmarks, and 9TB Oracle tablespace for SLOB are used to keep storage cache read-hit under 1% for 8KB random reads. We also use long run times to get stable, accurate and repeatble results.

 

Below are testing results we published in the whitepaper.

    From the table above, VSP inline compression only introduces very minimum performance impact, only 3.0% in turns of IOPS and TPS. This technology brings down TCO to customers without sacrificing performance!

 

    UCP 6000 for Oracle RAC solution with VSP F800 is well suited to run high performance business-critical Oracle OLTP and OLAP workloads. Unlike many other AFAs or mid-range storage systems, VSP F800 supports mature enterprise class features like local, remote, active-active array-based replication technologies.  The following benefits are also available to customers  - Easy Management, Fast Service Delivery, Application-Specific Provisioning, Block & File Access.
