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.

The Benefits of PCI Hot Plug Technology 3
Overview
Customers today need improved availability solutions that minimize or eliminate downtime. Compaq addresses this need by providing PCI Hot Plug technology that allows a PCI adapter to be added, upgraded, or replaced while the host system is running and while other adapters in the system provide uninterrupted service. PCI Hot Plug technology adds to other high-availability solutions presently available from Compaq such as Recovery Server Options, Redundant Netelligent Network Interface Controllers (NICs), hot-pluggable power supplies, hot-pluggable fans, and hot-pluggable SCSI drives.
Cost of Downtime
Compaq’s decision to develop PCI Hot Plug technology is focused on addressing a key customer issue: as computing environments grow more complex, the business costs of unplanned downtime are soaring. The increasing cost of unplanned downtime in business-critical environments, compounded by the time spent tracking the source of network or component failures, is creating a greater need for improved higher availability solutions like PCI Hot Plug. Due to the growing reliance upon computer networks, events resulting in system downtime, whether planned or not, can cripple an organization. Regardless of the cause, the common denominator to all system downtime is a high cost to a customer’s business.
A survey of 450 Fortune 1000 companies by Find/SVP1 found that the average outage across industries lasts four hours and costs $330,000. A typical company experiences nine outages per year, resulting in annual losses of almost $3 million (excluding the cost of lost employee productivity). Actual costs of downtime, however, can vary widely based on individual company size, business type, industry application environment, and type of outage.
Table 1 illustrates the financial impact of system downtime on various industries.

5 days/week
As a result of the astronomical costs associated with downtime, the vast majority of companies today require nonstop access to their critical systems. This trend was recently highlighted in a study conducted by the Standish Group International.3 According to the study, 46 percent of the Fortune 1000 companies require systems availability seven days a week, 24 hours a day (7x24). An additional 39 percent stated that systems were required to be accessible five days a week, eight hours a day. The study also showed that the vast majority of businesses today measure tolerable downtime in mere seconds or minutes. As illustrated in Figure 2, 34 percent of the Fortune 1000 companies can tolerate no more than three seconds of downtime on their business­critical applications. Another 37 percent of these customers require recovery from a failure in less than 3 minutes.
