Submission + - Oracle's largest internal database: 101TB (techtarget.com)

BDPrime writes: Oracle's largest internal database is 101 terabytes large, and it runs Oracle's own email and collaboration software called Beehive. It handles more than 140,000 users and 3.5 million emails per day. Oh, and it runs on nine Oracle Exadatas, the company's big integrated database servers.

Submission + - VMware memory management on Intel Nehalems (techtarget.com)

BDPrime writes: IT pros say the new memory management features and virtualization capabilities in the latest x86 processors are welcome, but the complexity involved can be challenging. One of them is dealing with VMware's memory management when running on Intel's Nehalem and AMD's Opteron chips, where features become confusing and perceptions can become a problem.

That's assuming every watt that goes into the data center gets to the IT load. Though it says in the documents for the facility that they're going to make it energy efficient, power still needs to be used for air conditioning, redundancy, facility lighting, security, etc. Assuming a PUE of 1.5 (PUE is total facility power divided by IT load), which is very efficient, you're talking about 85,000 servers.

But even that assumes all the IT load will be for servers. Certainly there will be power going to servers, network switches, etc., so the total would be lower than that. And if the NSA is using any larger servers (which considering its history, it most likely is), the number could be substantially lower than that. The average power consumption for a TOP10 supercomputer in 2008, for example, is about 1.3 megawatts, which in itself equals 2,600 500-watt servers.

Submission + - NSA to build $1.6 billion data center in Utah (techtarget.com)

BDPrime writes: "President Barack Obama has authorized Congressional spending of $1.6 billion over the next four years for a massive National Security Agency data center in Utah.

The data center will have 65 megawatts of potential load, enough to power all the homes in Salt Lake City. It will be located at Camp Williams, a military base just south of Salt Lake City. Initial spending for the facility, to be located on a 200-acre site, is $169.5 million. Officials hope to begin construction in September and finish next May."

Submission + - Windows on a mainframe: nested hypervisors (searchdatacenter.com)

bdprime writes: "As a follow-up to "Microsoft Windows, on a mainframe": Mantissa's z/VOS software will actually be a hypervisor that will sit on top of z/VM, the mainframe's hypervisor-based virtualization operating system. But end users are worried about a host of issues, including performance of Windows when in nested hypervisors and potential legal and licensing issues that could come with the product."

Submission + - Data center air conditioner fans: Why they matter

BDPrime writes: When people think about energy savings, data center air-conditioning fans don't necessarily leap to mind. But choosing the right fan design can save up to $50,000 per fan over a 15-year lifespan.

Up to 37% of a data center's energy costs can be attributed to cooling infrastructure, according to EYP Mission Critical Facilities. A central part of cooling data centers is moving the air, and a big part of air movement is the cooling unit's fans. Incremental changes in the type of fan, airflow direction and fan speed offer opportunities for energy efficiency in the data center.

Submission + - Wind-powered data center for Google 3

TT writes: Google is considering building a wind-powered data center in Greensburg, Kan. In addition to the huge solar-panel project it's building in Mountain View, this 20-megawatt data center in Greensburg would go a long way toward helping Google get carbon neutral, as is its goal. The company, like the entire universe today, is on the green kick. It announced last month that it wants to make renewable energy cheaper than coal.
It's funny.  Laugh.

Submission + - University holds jazz funeral for its mainframe

BDPrime writes: "Server Specs has a story about The University of Manitoba holding a New Orleans-style jazz funeral for its mainframe. The funeral included a full procession route on campus, "Amazing Grace" being played on the trumpet, and employees smashing a pinata made to look like a cartoon-y mainframe. Is the mainframe dead? Maybe not everywhere, but at The University of Manitoba it certainly is."

Submission + - Data center bust coming? (techtarget.com)

An anonymous reader writes: Blogger and data center manager Chuck Goolsbee says the data center bust is coming. He cites the Savvis and Navisite stock plunges as an early indicator. From the article: The big money is flowing, so data center operators are building what they can, while they can... Are they overbuilding? Of course they are. They are banking space now to tide them over after the capital flow stops, because it will stop. If history is a guide, the stop will come sometime in the next year or two.

Submission + - Demonstration of OpenSolaris on the mainframe 1

BDPrime writes: Sine Nomine Associates, the company working on porting OpenSolaris to the mainframe, is demonstrating the technology at the Gartner Data Center conference this week. David Boyes, the president, is giving the demos at the IBM booth with the support of Sun Microsystems. He said it will be ready for mainframe users "soon," but wouldn't divulge more than that.

It's a five-part video series on YouTube that could take up some time, but the demo, which is mostly in the last video, is pretty cool.
IBM

Submission + - IBM: It's our mainframe and we'll do what we want (techtarget.com)

BDPrime writes: IBM is now apparently making it harder for mainframe resellers to resell the mainframe. This according to a quarterly earnings call from a mainframe reseller, QSGI, who said IBM's restrictions on a reseller's ability to upgrade and downgrade a machine for a user are diminishing the benefit of buying a refurbished mainframe. From a story in The Register:

IBM has a colossal claim to the mainframe marketplace, and can largely dole out its own terms to customers. When another business starts using IBM's own hardware to compete, IBM has a tendency to roll up its sleeves.

Submission + - Server densities hampered by depths

BDPrime writes: "With all this talk about server density — fitting more power into the same box — there's one factor in the equation that some people forget about: server depths. Yes, it's a problem. While vendors build servers that can fit more processors and more cores into a 1U server rack space, the problem is that many of their products are so deep that they stick out the front of the racks, forcing data centers to space the racks farther away from one another, which takes up valuable floor space. Anyone else have this problem?"

Submission + - A solar-powered data center....on a dirt road?

BDPrime writes: "AISO.net has an almost 100% solar-powered data center that sits on a dirt-road property where the owner's three dogs roam at will, catching shade underneath the solar panels when it gets really hot. The owner, Phil Nail, also despises the notion of carbon offsets, which allows companies to pretend they're green by paying someone else to be green in their place."
