EMC adds unstructured big data analytics to Greenplum platform

EMC’s Greenplum subsidiary recently announced a new capability to its Hadoop Data Computing Appliance (DCA) that allows users to mix and match unstructured and structured data analytics platforms.

EMC also announced its Greenplum Analytics Workbench, a 1,000-plus-node test bed for software integration tests of Apache Hadoop software.

The test bed provides the Hadoop open source community with the testing resources to quickly identify bugs, stabilise new releases and optimise hardware configurations in an effort to speed up the innovation of Hadoop, the company said. All testing and results will be given back to the Apache Software Foundation and the open source community, it was reported.

EMC’s testing will be planned in coordination with the Apache Hadoop project, sources said.

On its Greenplum appliance product front, EMC introduced the Modular Data Computing Appliance, which allows users to combine a massively parallel processing relational database with enterprise-class Apache Hadoop in a single, unified appliance to achieve structured and unstructured data processing.

Greenplum introduced the Data Computing Appliance in October 2010. An updated version of the DCA that included a Hadoop appliance was released this past May .

The Greenplum HD (Hadoop) DCA is built on top of Intel X86 servers and uses both a structured database built by Greenplum, which EMC acquired last year , and the Apache open-source version of Hadoop. The older version of the appliance is based on Sun Fire x64-based servers.

According to Scott Yara, co-founder of Greenplum and vice president of products for EMC ‘s Data Computing Division, administrators can read and write files in parallel from Greenplum to HDFS (Hadoop File System), enabling rapid data sharing. Cross-platform analysis can be performed using Greenplum SQL and advanced analytic functions accessing data on HDFS.

“The new Modular DCA adds high-performance computing modules in the form of SAS Institute’s In-Memory Analytics software, allowing it to serve up both structured data, such as databases, and unstructured file data,” said Yara.

“The main change is that it can perform parallel processing using server memory through the use of business analytics software [from SAS] ,” Yara added. “We wanted to offer a Lego building block-type architecture.”

According to EMC, through the use of the SAS software, structured and unstructured data can exist on multiple x86 hosts, the purpose of which is to allow users to perform computations in memory on each server node in a clustered configuration.

“The power of the appliance is that it can perform all these complex problems in parallel,” Yara said.

“The new Modular DCA is undergoing product trials and is expected to be available by the end of this year,” Yara said.
