IBM announced a new marketing program intended to entice customers into using Linux on x86 servers running the Linux/Apache/MySQL/PHP (LAMP) stack of web server software. While running LAMP applications, a full rack of five p5-560Q systems running at 70% utilization can replace 320 x86 servers that take up nearly eight racks of space and power, IBM executives said at LinuxWorld.
The new p5-560Q system will use a faster version of the Power5+ processor running at 1.8GHz. The systems will employ IBM's Quad-Core Modules, fitting two dual-core Power5+ chips into a single package. Eight such chips will fit into a single system.
New features for the OpenVZ open source virtualization project
OpenVZ has announced the availability of new features in its operating system server virtualization software. Those updates are now available for download and include:
- Delivery of checkpointing and live migration support for IA64 processors. This allows system administrators to move virtual servers between physical servers without end-user disruption or the need for costly storage capacity.
- Network file system (NFS) support, which makes it possible to access network disk files from within OpenVZ virtual environments.
- VLAN (IEEE802.1Q) network standard support in virtual environments, so that every network packet can be tagged to some distinct network.
- Filesystem in userspace (FUSE) support, which allows for an FTP or SSH server to be presented like a file system within a virtual environment.
- I/O accounting for each virtual environment, to be followed shortly with a new per-VE I/O scheduling feature. This solves the problem of distributing I/O throughput (which can be a performance bottleneck) across all virtual environments. The scheduling feature will make it possible to set priorities so that some VEs can be set as "high priority" for disk access, and others as "low priority."
