Location: |

Host: |
Professor A. Bilas |
Abstract: |
This talk will cover the architecture of ESX server, VMware's data
center-class virtualization product. The main focus of the talk will
be on the architecture of the storage stack in ESX's proprietary
kernel. I will motivate the need for encapsulating virtual machine
(VM) state in special containers that are safely shared on Storage
Area Networks and explain how we achieve that in ESX. I will then
describe how we take advantage of those properties of VM storage to
enable a range of solutions for VM high availability, mobility and
disaster recovery. I will conclude the talk with a list of future
directions and open issues that are interesting from a research
perspective. |

senior engineer at VMware where he leads the R&D team that develops
VMware's data protection products. In addition to product development,
he is the closest thing VMware has to a storage systems researcher.
Before being involved in product development, he was a researcher
at HP Labs, where he led HP's research efforts in the space of
distributed file systems and storage QoS. He holds a PhD on Distributed
Computing from Imperial College (where he also taught for a few
years and was offered a tenured lectureship) and a Diploma on
Computer Engineering from the University of Patras. He has had
more than 20 papers published in refereed journals and conferences
and he holds 7 US patents. He is active in the research community
by participating in conference program committees and by collaborating
in research projects with universities such as CMU, Duke and UC
Santa Cruz. For more details, see http://www.karamanolis.org/christos/index.html . |
