Use virtualization to boost energy efficiency

One technology that can help companies increase efficiency is virtualisation, which can play multiple roles in the datacentre.

Virtualisation makes it possible, for example, to divide a single server into smaller virtual servers, or pool smaller, individual machines so they can perform as one larger system. Gartner estimates that more than 90 percent of companies using virtualisation are doing so to reduce x86 server space and costs. In fact, the company estimates that virtualisation cut the x86 server market by four percent in 2006.

Power savings can be even greater when addressing storage assets. Storage resources - which IDC says are growing 50 percent per year - are among the largest consumers of energy in the datacentre, in most cases consuming 13 times more power than processors. What's more, use of storage assets is often 25 percent or less, making this environment almost as inefficient as x86 servers.


I have been saying this for quite a while, so lets get started!

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.

Virtualization: GlassHouse hopes to cash in with its IPO!

GlassHouse Technologies Inc. on Tuesday registered to raise as much as $100 million in an initial public offering that, despite the company's financial losses, could prove a hit with investors drawn to its focus on "virtualization" technology. The Framingham, Mass., company offers consulting services for companies that use virtualization software to improve the performance of corporate servers and cut costs in their data centers. GlassHouse also provides Internet-based data storage. "Software-as-a-service," or SaaS, companies and vendors of virtualization products have proved popular among investors in recent years as corporate customers seek alternatives to conventional packaged software. GlassHouse, with roots in both sectors, will test the strength of that interest, said Peter Falvey, managing director with Boston investment bank Revolution Partners. "It will be a bit of a bell weather," he says. "It's not as though it's the 15th SaaS m...
