EMC plucks Greenplum

Charges into data warehousing & BI


EMC is getting into the data warehousing / business intelligence (DW/BI) area by buying Greenplum. This takes it into direct competition with Oracle and its Exadata product line.

Greenplum has about 100 customers, including the New York Stock Exchange and T-Mobile USA. And it is to be the foundation of a new data computing product division within EMC’s Information Infrastructure business.

The company develops DW/BI software with a “shared-nothing” massively parallel processing (MPP) architecture that operates in virtualised X86 servers and EMC thinks Greenplum fits perfectly into its private cloud, virtualised server and federated storage worlds.

There's an open source angle too: Greenplum's software is based on the PostgreSQL database

So why Greenplum?

There is an explosion in the use of digital sales channels and mobile internet devices. This creates a parallel explosion in data about online sales, and the faster that data can be accessed in a data warehouse and analysed by a business intelligence application, the faster a business can identify profitable and unprofitable sales trends and maximise the former and minimise the latter.

If businesses can run their DW/BI systems in near real-time then that gives them a better ability to optimise their product and pricing mix.

An EMC insider says that Greenplum reduced a 10-hour query in a traditional system to six minutes for O'Reilly Media. The customer used to make one BI run a day and now runs six an hour.

Using Greenplum software, data is automatically partitioned across multiple "segment" servers, and each "segment" owns and manages a distinct portion of the overall data. Its database is able to hold and and access warehoused data better than standard relational databases, with the result that BI queries run faster.

Chorus line

Greenplum has a product called Chorus with which IT and DBAs can establish "one or more pool of commodity servers and storage ahead of demand, and can then create new database instances and sandboxes in minutes with just a few clicks. These databases could be small sandboxes on just a couple of servers, or they could be multi-petabyte marts across hundreds of servers. Pools can be expanded by adding more servers, and the databases can themselves grow to span more servers and storage using Greenplum Database's online expansion capabilities."

Two years ago EMC set up a DW/BI competency centre. At that point HP had announced a tie-up with Oracle to produce the HP Oracle Database machine. Greenplum was then working with Sun on the X4500 Thumper hardware. Since then Oracle bought Sun and replaced the HP hardware with Sun's in its Exadata system.

EMC will continue to offer Greenplum’s full product portfolio to customers. It also plans to deliver "new EMC Proven reference architectures as well as an integrated hardware and software offering designed to improve performance and drive down implementation costs".

In other words we can expect an EMC Exadata-type system. That system includes server hardware, which EMC does not make. There is a possibility then, that we will see a Greenplum V-block, using VMware virtualisation, Cisco UCS servers and EMC storage.

It's a deal

Greenplum's CEO, Bill Cook, will run the new data computing product division and report to Pat Gelsinger, the president and COO for EMC's Information Infrastructure Products division.

The all-cash acquisition is expected to be completed by the end of September - the cash amount has not been revealed. Greenplum has reportedly raised around $61m of funding, so a price of $100m to $150m might be in the right ballpark.

  • DigitalOcean tries to take sting out of price hike with $4 VM
    Cloud biz says it is reacting to customer mix largely shifting from lone devs to SMBs

    DigitalOcean attempted to lessen the sting of higher prices this week by announcing a cut-rate instance aimed at developers and hobbyists.

    The $4-a-month droplet — what the infrastructure-as-a-service outfit calls its virtual machines — pairs a single virtual CPU with 512 MB of memory, 10 GB of SSD storage, and 500 GB a month in network bandwidth.

    The launch comes as DigitalOcean plans a sweeping price hike across much of its product portfolio, effective July 1. On the low-end, most instances will see pricing increase between $1 and $16 a month, but on the high-end, some products will see increases of as much as $120 in the case of DigitalOceans’ top-tier storage-optimized virtual machines.

  • GPL legal battle: Vizio told by judge it will have to answer breach-of-contract claims
    Fine-print crucially deemed contractual agreement as well as copyright license in smartTV source-code case

    The Software Freedom Conservancy (SFC) has won a significant legal victory in its ongoing effort to force Vizio to publish the source code of its SmartCast TV software, which is said to contain GPLv2 and LGPLv2.1 copyleft-licensed components.

    SFC sued Vizio, claiming it was in breach of contract by failing to obey the terms of the GPLv2 and LGPLv2.1 licenses that require source code to be made public when certain conditions are met, and sought declaratory relief on behalf of Vizio TV owners. SFC wanted its breach-of-contract arguments to be heard by the Orange County Superior Court in California, though Vizio kicked the matter up to the district court level in central California where it hoped to avoid the contract issue and defend its corner using just federal copyright law.

    On Friday, Federal District Judge Josephine Staton sided with SFC and granted its motion to send its lawsuit back to superior court. To do so, Judge Staton had to decide whether or not the federal Copyright Act preempted the SFC's breach-of-contract allegations; in the end, she decided it didn't.

  • US brings first-of-its-kind criminal charges of Bitcoin-based sanctions-busting
    Citizen allegedly moved $10m-plus in BTC into banned nation

    US prosecutors have accused an American citizen of illegally funneling more than $10 million in Bitcoin into an economically sanctioned country.

    It's said the resulting criminal charges of sanctions busting through the use of cryptocurrency are the first of their kind to be brought in the US.

    Under the United States' International Emergency Economic Powers Act (IEEA), it is illegal for a citizen or institution within the US to transfer funds, directly or indirectly, to a sanctioned country, such as Iran, Cuba, North Korea, or Russia. If there is evidence the IEEA was willfully violated, a criminal case should follow. If an individual or financial exchange was unwittingly involved in evading sanctions, they may be subject to civil action.

  • Meta hires network chip guru from Intel: What does this mean for future silicon?
    Why be a customer when you can develop your own custom semiconductors

    Analysis Here's something that should raise eyebrows in the datacenter world: Facebook parent company Meta has hired a veteran networking chip engineer from Intel to lead silicon design efforts in the internet giant's infrastructure hardware engineering group.

    Jon Dama started as director of silicon in May for Meta's infrastructure hardware group, a role that has him "responsible for several design teams innovating the datacenter for scale," according to his LinkedIn profile. In a blurb, Dama indicated that a team is already in place at Meta, and he hopes to "scale the next several doublings of data processing" with them.

    Though we couldn't confirm it, we think it's likely that Dama is reporting to Alexis Bjorlin, Meta's vice president of infrastructure hardware who previously worked with Dama when she was general manager of Intel's Connectivity group before serving a two-year stint at Broadcom.

  • Lithium production needs investment to keep pace with battery demand
    Report says $42b will need to be poured into industry over next decade

    Growing demand for lithium for batteries means the sector will need $42 billion of investment to meet the anticipated level of orders by the end of the decade, according to a report.

    Lithium is used in batteries that power smartphones and laptops, but there is also rising use in electric vehicles which is putting additional pressure on supplies.

    The report, Benchmark Mineral Intelligence, predicts that demand will reach 2.4 million tons of lithium carbonate equivalent by 2030, roughly four times the 600,000 tons of lithium forecast to be produced this year.
