As business-critical applications place growing demands on system resources, increasing
.
.
.
system bandwidth becomes a vital issue. After evaluating available system architectures,
.
.
.
Compaq determined that a new system architecture would provide the higher levels of
.
.
.
performance, processor and I/O expandability, and bandwidth to satisfy the needs of
.
.
.
.
increasingly complex transaction, database, internet/intranet, and file/print applications.
.
.
.
The Highly Parallel System Architecture, introduced by Compaq in 1997, delivers the
.
.
.
greatest system bandwidth available today for such demanding applications.
.
.
.
.
.
This technology brief describes the Highly Parallel System Architecture.
