Live migration is an essential technology for an agile, dynamic data center environment based on server virtualization. Until now, it has not been possible, however, to perform successful live migration between servers based on different generations of processors, each with different instruction sets - this limited our ability to implement large resource pools, creating islands of servers and hindering the implementation of advanced data center capabilities.

Combined, Intel VT FlexMigration assist and Enhanced VMotion are designed to overcome this limitation by enabling all servers to expose the same instruction set to applications, even if they are based on different processor generations from a single CPU supplier.

Intel IT and Intel’s Digital Enterprise Group, End User Platform Integration, conducted proof-of-concept (PoC) testing of live migration using Intel® Virtualization Technology FlexMigration (Intel® VT FlexMigration) assist and the Enhanced VMotion feature of VMware ESX 3.5U2*. All migrations completed without problems and our testing demonstrated that we can use Intel VT FlexMigration assist for live migration of Intel IT business applications in a mixed production environment. As a result, we can create resource pools that combine servers from multiple generations, eliminating incompatible islands of servers and allowing full implementation of advanced data center capabilities. Accordingly, we expect to standardize on systems with Intel VT FlexMigration assist in the future.

Our recently published IT@Intel white paper:  Testing Live Migration with Intel® Virtualization Technology FlexMigration' documents the details pertaining to our tests – the types of systems tested, the workloads used, different scenarios examined and the results.

On behalf of our team, I’d like to invite you to view this whitepaper and comment about how you are using or intending to use these technologies in your datacenters and your experiences to-date with these capabilities.

As this is my first blog on this forum, I'd like to introduce myself. My name is Bill Sunderland and I have been working at Intel for 12 years primarily working on Server Hardware Engineering and the last three years of which I have focused my efforts on Program Managing the Virtualization Engineering release for Intel IT. I have recently published a WP demonstrating the methodology used as described below.

Intel IT planned, engineered, and has begun deploying a virtualized business-computing production environment at several data centers, a rollout that will continue through 2008. Our initiative has already confirmed anticipated virtualization benefits such as faster, more automated deployment. We are initially consolidating older servers running applications that are not mission-critical; we see opportunities to achieve 16:1 consolidation ratios.

I would be interested in hearing your experiences and/or questions regarding virtualizing IT environments!

Like most other companies these days, Intel is facing a growing demand for computing resources. As a result, our computing costs are going up along with that demand. All of these issues prompted us to take a hard look at our data center strategy, to see where we could make it more efficient.

Therefore, we’ve launched into a significant undertaking. We’ve started the process to End of Life (EOL) or consolidate our data centers down to just eight strategic locations. This effort is planned to take us eight years, but we’re working to pull this in sooner. This initiative enables us to reduce costs, improve server and storage utilization, create higher density & more energy efficient data centers, and allows us to keep pace with our company’s rapid rate of innovation. The effort could deliver up to $750M in Net Present Value. View my video blog for more information.

I would be interested to hear your comments, questions and have you share with us what your company is doing to drive efficiency within your data centers.
