IBM: Go back to mainframes and earn CO2 credit

Quoting CW:

IBM will announce Friday a program that will make it possible for its customers to document server energy savings -- and even trade them for cash, if they want, on emerging carbon markets.

IBM says it's the first in this industry to offer such a program, and though it's initially making it available only for its mainframes, the company plans to extend it to all of its server lines and storage systems as well.

How it works: If you take distributed systems -- for instance, x86 servers -- and consolidate them on a mainframe, the move will result in an energy savings. Those savings can be calculated based on reference data, a task that will fall to Neuwing Energy Ventures, an independent firm verifying and trading in energy efficiency certificates.

More specifically, IBM said its ongoing consolidation of 3,900 distributed systems onto 33 mainframes will eventually save the company 119,000 megawatt hours annually. The megawatt hours of savings that Neuwing will calculate will include the total savings to power and cool the data center. One energy efficiency certificate is issued for each megawatt hour saved per year.

In IBM's example, the certificates would have an estimated value of between $300,000 and $1 million based on market conditions, said Rich Lechner, IBM's vice president of IT optimization. The certificates can be issued for each year of the life of the project.

"The value of these certificates is minute to the real energy savings and the real operational savings that you're going to realize," said Lechner.

Security: VMware Workstation 6 vulnerability

vulnerable software: VMware Workstation 6.0 for Windows, possible some other VMware products as well type of vulnerability: DoS, potential privilege escalation I found a vulnerability in VMware Workstation 6.0 which allows an unprivileged user in the host OS to crash the system and potentially run arbitrary code with kernel privileges. The issue is in the vmstor-60 driver, which is supposed to mount VMware images within the host OS. When sending the IOCTL code FsSetVoleInformation with subcode FsSetFileInformation with a large buffer and underreporting its size to at max 1024 bytes, it will underrun and potentially execute arbitrary code.

Splunk that!

Saw this advert on Slashdot and went on to look for it and found the tour pretty neat to look at. Check out the demo too! So why would I need it? WHY NOT? I'd say. As an organization grows , new services, new data comes by, new logs start accumulating on the servers and it becomes increasingly difficult to look at all those logs, leave alone that you'd have time to read them and who cares about analysis as the time to look for those log files already makes your day, isn't it? Well a solution like this is a cool option to have your sysadmins/operators look at ONE PLACE and thus you don't have your administrators lurking around in your physical servers and *accidentally* messing up things there. Go ahead and give it a shot by downloading it and testing it. I'll give it a shot myself! Ok so I went ahead and installed it. Do this... [root@tarrydev Software]# ./splunk-Server-1.0.1-linux-installer.bin to install and this (if you screw up) [root@tarrydev Software]# /op

Virtualization is hot and sexy!

If this does not convince you to virtualize, believe me, nothing will :-) As you will hear these gorgeous women mention VMware, Akkori, Pano Logic, Microsoft and VKernel. They forgot to mention rackspace ;-) virtualization girl video I'm convinced, aren't you? Check out their site as well!
