Oracle has announced the availability of Oracle Big Data Appliance, an engineered system of hardware and software that incorporates Cloudera’s Distribution, Including Apache Hadoop with Cloudera Manager, plus an open source distribution of R. Big Data Appliance, which runs on Oracle Linux, also features Oracle NoSQL Database Community Edition and Oracle HotSpot Java Virtual Machine. In addition, Oracle simultaneously announced the availability of Oracle Big Data Connectors, a software product that helps customers easily integrate data stored in Hadoop and Oracle NoSQL Database with Oracle Database 11g. This system scales by connecting multiple racks together via an InfiniBand network.

Oracle has produced a true SPARC Engineered System that integrates Solaris on SPARC, Exadata and Exalogic. And this new system is the Oracle SPARC Supercluster, which is built on the new T4 chip and its new architecture, which has resulted in the SPARC T4-4 Server as the the top of the line 5RU model. SPARC Supercluster also includes the integration of Infiniband and the flexibility of Logical Domains (LDoms) as well as a ZFS Storage Appliance to support the Exalogic clustering storage needs, plus Exadata Cells.]

In his post Enabling HPC with InfiniBand in Java Applications Ricardo Ferreira argues that the maturity and e bandwidth advantages of InfiniBand give it an edge over Fibre Channel and Ethernet as the choice for a network fabric. He argues that InfiniBand's capability to move data directly from the memory of one computer to another, bypassing the operating systems of both in the operation, gives it a performance advantage in HPC settings. It is the enabling of Sockets Direct Protocol (SDP) support in InfiniBand, he concludes, that is the key to maximizing the performance of Java applications.

In her OTN article on creating a robust platform for SAS Grid Computing that uses the Sun Blade 6000 Modular System and the Sun ZFS Storage 7420 Appliance, Maureen Chew concludes that this particular blade/storage appliance combination and the Solaris 10 OS constitute an ideal environment for SAS Grid Computing applications. She writes that 30 compute hours in the SAS Grid Mixed Analytic workload finished in approximately 45 minutes, adding that a mirrored pool across two disk shelves was found capable of delivering more than 3 GB/sec of I/O throughput. Tests using a single PCIe, dual-ported, InfiniBand connection from the Sun ZFS Storage 7420 appliance performed roughly equivalent to a quad 10 GbE link aggregation despite the expectation that the quad 10 GbE might perform 20% to 25% better.

Oracle's SPARC T4 processors are expected to be released in the fall of 2011 with volume shipments slated for 2012. Also forthcoming in 2011 is the release of Solaris 11. Yet another T-Series server product refresh is expected in 2013, scheduled to be coincident with another update of Solaris 11, writes Lloyd Cohen. He calls the T4 an inflection point in the T-Series designs, because it improves single-thread performance beyond what it was in the T3 processors.
