Virtual Interface (VI)
Architecture
- The New Open
Standard for Distributed
Messaging Within a Cluster
This paper will discuss the VI Architecture concept, its key components, its
benefits, its relationship to the SAN, how Compaq envisions utilizing VI
Architecture, and where VI Architecture is headed in the industry standards
community
.
Abstract:
As business and technology requirements drive Intel-based
servers to become clustered, a need for a high-speed, low latency
communications service will be a requirement. This requirement for high-
speed communication is further exacerbated as clusters grow from the
current 2 node cluster to multi-node clusters which can approach 16 – 32
nodes in some currently proposed configurations. This service should not be
encumbered by traditional multi-point protocols such as TCP/IP.
With these requirements in mind, Compaq has taken a leadership role in
creating and defining the Virtual Interface (VI) Architecture.
VI is a
distributed messaging technology that has been authored by Compaq, Intel,
and Microsoft. The specification, published December 16, 1997, provides
an open architecture promoting clustered computing with a transport layer
and Application Programming Interface (API) which can be utilized by
software and hardware vendors to provide high-speed and low latency
communications between servers in clustered server and storage
configurations. This concept is called a System Area Network (SAN).
VI Architecture is designed to be hardware independent and compatible
with current network interconnects such as ServerNet, Ethernet, and ATM.
This ability to rely on existing communications adapters and media will
help migrate existing protocols to VI Architecture. Since VI Architecture is
also processor independent, it will allow the architecture to be implemented
into silicon, therefore further improving communication performance.
Compaq will develop clusters of ProLiant Servers and/or NT Workstations
to demonstrate its ability to perform in the high end of the enterprise market
space. Compaq’s initiative in developing and setting standards such as VI
Architecture, in partnership with Intel and Microsoft, further strengthens its
presence in the IT marketplace as a high-volume, low-cost supplier of
quality x86 servers and workstations for enterprise level solutions.
