The Benefits of PCI Hot Plug
Technology
This white paper summarizes Compaq PCI Hot Plug technology
strategy, discusses Compaq’s leadership role in the development of
the industry standard, and explains the benefits of Compaq’s
implementation of the PCI Hot Plug standard to help organizations
maximize productivity by decreasing server downtime
.
Abstract:
As an increasing number of companies migrate their
business-critical applications to industry-standard servers, the need
for redundant features and hot-pluggable components to minimize
system downtime is increasing.
Each downtime event affects more
people at ever-increasing costs.
The need has grown beyond “high
availability” toward “approaching continuous availability”.
Continuous availability requires the
elimination not only of unplanned
downtime but a reduction of
planned downtime as well.
Compaq Computer Corporation, the
world’s leading server provider, has
historically taken a leadership role
in the development of such
industry-standard technologies that are approaching continuous
system availability.
With the development of PCI Hot Plug
technology, an industry standard, Compaq strengthens its role in
providing the highest levels of I/O availability solutions for the
distributed enterprise.
PCI Hot Plug offers unprecedented server availability by allowing
users to replace, upgrade, and add PCI adapters to the PCI local bus
without powering down the server.
PCI Hot Plug technology
benefits also include customer investment protection and efficient
manageability and serviceability.
In addition, with the release of the ProLiant 6500 and ProLiant 7000,
Compaq made the chassis and electronics design changes required
for safe and efficient removal and insertion of PCI adapters without
powering down the server.
Next-generation PCI Hot Plug solutions
are included in Compaq’s newest enterprise server, the Pentium II
Xeon Model of the ProLiant 7000, released in June 1998.
