While green IT is pursued for a number of reasons (eco-responsibility,
CAPEX/OPEX, facility constraints, etc.), a green IT strategy often has
unforeseen benefits (increased manageability, security, business
This presentation will explore how Red Hat has and continues to
contribute to the green IT movement. While there are many ways of going
green, Chris Runge, a director of solutions architects at Red Hat, will
discuss four of them:
- UNIX-to-Linux migration: UNIX-to-Linux migrations facilitated green
computing before the term “going green” was popular. As customers
migrated from RISC systems to industry-standard systems running Linux,
they were able to achieve higher performance with less hardware and
lower power consumption.
- Power management technologies: Runge will discuss Red Hat's
involvement with power management technology, including LessWatts.org.
Emerging improvements, which include: RHEL 5.3 and Nehalem, the
tickless kernel, improved drivers, and improved coding techniques, will
also be discussed.
- Virtualization: Virtualization provides many benefits to a
green IT strategy, from server consolidation to the increased benefits
of Red Hat Enterprise virtualization's system scheduler and power-saver
technologies. In addition to these benefits, Runge will discuss the
benefits of emerging approaches, which include KVM's architectural
approach (relative to power savings), cloud computing, and VDI.
- The mainframe: Runge will highlight a migration to the
mainframe as a path to green IT with a discussion of the Bank of New
