Hitachi's CoolCenters50 and Harmonious Green

Hu has something to tell about it:

In September of this year Hitachi ltd, our parent company announced a program in Japan that is known as CoolCenter50 which is targeted at reducing power consumption in their Yokohama and Okayama data center by 50% in 5 years. This effort encompasses all of the groups in Hitachi including, air conditioning, power generation, IT equipment and management software.

In support of this goal, Naoya Takahashi, the Executive General Manager and Vice President of the Information and Telecommunications Group announced last week the Harmonious Green Plan which aims to reduce 330,000 tons of CO2 in the next 5 years through the development of power saving IT products. Dr. Takahashi is the same Takahashi who is credited with the development of the USP storage virtualization platform and its predecessor, the Lightning 9990. So when Takahashi-san states that this is the goal, there is a track record that gives it a great deal of credibility. The amount of reduction is calculated from the predicted CO2 emissions which would have accumulated if Hitachi’s shipping volume of IT products in the fiscal year 2007 remains constant for the next 5 years.

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.

OS Virtualization comparison: Parallels' Virtuozzo vs the rest

Virtuozzo's main differentiators versus hypervisors center on overhead, virtualization flexibility, administration and cost. Virtuozzo requires significantly less overhead than hypervisor solutions, generally in the range of 1% to 5% compared with 7% to 25% for most hypervisors, leaving more of the system available to run user workloads. Customers can also virtualize a wider range of applications using Virtuozzo, including transactional databases, which often suffer from performance problems when used with hypervisors. On the administration side, customers need to manage, maintain and secure just a single OS instance, while the hypervisor model requires customers to manage many OS instances. Of course, the hypervisor vendors have worked hard to automate much of this process, but it still requires more effort to manage and maintain multiple operating systems than a single instance. Finally, OS virtualization with Virtuozzo has a lower list price than the leading hypervisor for comme...
