2nd Data Center Converged and Virtual Ethernet Switching
Workshop (DC CAVES)
http://www.i-teletraffic.org/itc22/workshops/dc-caves-workshop/
September 6 2010, Amsterdam, The Netherlands
collocated with the
22nd International Teletraffic Congress (ITC 22)
Introduction
The traditional data center (DC) compute model, especially in the
x86 space, has consisted of lightly utilized servers running a
bare metal OS or a Hypervisor with a small number of virtual
machines (VMs). In this traditional model, servers attach to the
network lower bandwidth links, such as 1 Gbps Ethernet and 2 or 4
Gbps Fibre Channel. This physical compute model suffers from two
major issues: high capital expenses due to underutilized servers
and multiple fabrics; and high operational expenses due to manual
administration of many management tools. As such, the management
tasks have been focused on maintaining the infrastructure and not
on the services that are provided by the infrastructure to the
business.
In our view data centers are undergoing a major transition towards
a converged and virtualized compute model. This new model allows
for construction of flexible IT capability that enables the
optimal use of compute and information to support business
initiatives. This model has many highly utilized servers running
many VMs per server, using high bandwidth links to communicate
with virtual storage and virtual networks both within and across
data center sites. For networking within the data center the
potential value of this new model comes from: lowering capital
expenses through higher utilization (server, storage and network),
and converged fabrics; and lowering operational expenses through
automated and integrated management that optimizes data center
infrastructure. At the edge of the data center, virtual networking
(e.g. MPLS, VPLS) also offers tremendous savings associated with
combining networks, especially across the wide area network with
its expensive WAN links.
Scope
Organized together with ITC 22, the second DC CAVES workshop is
intended to serve as a forum to present the latest work by
researchers and developers from both academia and industry. The
workshop focuses on the technologies that will be needed to meet
the demands of the new virtual and converged compute model
described above. For each of these technologies the workshop will
analyze the problem and solution alternatives.
The two major topics of interest are server virtualization
infrastructure and physical switch virtualization infrastructure:
* Server virtualization infrastructure
- Server input/output virtualization enhancements
- Automation of virtual server network identity management
- Enhanced virtual server network access and traffic controls
- Networking technologies to enable server migration within an
entire DC
- Networking technologies to enable virtual server migration
across DCs
- Security plane infrastructure virtualization (e.g. enhanced
virtual appliances running in server virtual machines)
- Enhancements to virtual Ethernet switches used by virtualization
intermediaries (e.g. Hypervisors)
- IEEE 802.1Qbg Ethernet virtual bridging mechanisms (Virtual
Ethernet Bridging, Virtual Ethernet Port Aggregation,
Virtual Station Interfaces, Trivial TLV Transport Protocol)
- IEEE 802.1Qbh Bridge Port Extension mechanisms
- Offloading of virtual switching to external fabrics
- Converged fabric reference services architectures
- Future directions
* Virtual & converged fabric infrastructure
- Overall network virtualization & performance
- Layer-2/3/+ fabric virtualization technologies (e.g. MPLS, VPLS,
switch stacking and mechanisms that partition a single physical
switch into multiple virtual switches)
- Enhancements to convergence technologies (e.g. CEE, DCBX, iSCSI,
NAS, FCoE, FC over MPLS)
- Performance evaluation of converged iSCSI, NAS and emerging FCoE
fabrics
- Converged fabric security considerations
- Transport stack options converging Inter-Process Communication
(IPC) traffic
- Additional Ethernet quality of service enhancements needed for
converged environments
- Performance and fault event management for converged fabrics
- Converged fabric management infrastructure
- Converged fabric reference services architectures
- Future directions
