Organizations are under growing pressure to support non-stop business

operations without increasing the IT budget. Given their position at the

center of the IT infrastructure, servers play a critical role in determining

both the overall availability as well as the total cost of ownership of

that infrastructure.

To ensure high availability, a server must proactively respond to

failures, both within the server and the network to which it is attached.

High availability requires that a system administrator manage a server

without having to be colocated with that server, and that the server

remain available while a failed component is repaired.

SPECIAL ADVERTISING SECTION many factors combine to inﬂuence server availability. HP and Intel are developing sophisticated technologies like redundant Ethernet connections and network adapter teaming that enhance server availability and enable IT organizations to satisfy today’s business requirements. IT organizations to respond to industry trends, such as server consolidation and virtualization, that are driving the need for more network ports.

SPECIAL ADVERTISING SECTION cooling & power ﬁgure 3. There are two types of cooling redundancies. One allows users to run their server until they shut it down and replace the failed fan. The other maximizes server availability by permitting the failed fan to be changed while the system is still functioning. HP performs hundreds of system tests on each of its ProLiant servers. During these tests, the fans are independently stress tested. For greater reliability, only fans with ball bearings are used.
