organization or create several virtual servers on one LPr and then dedicate one of them to the
client. Processor density and speed as well as floor space considerations are very important in
a shared data center, as is the ability to install 20 servers in a single 2-meter rack.
Configurations
The HP NetServer LPr can be grouped into several different configurations. Two are discussed
here: clustering for availability and consolidation for improved space utilization, improved
security and easier management.
High Availability Solutions
The applications discussed so far in this paper have been presented as if they were installed on
single, stand-alone servers. There are several benefits that pairing or grouping servers in a
cluster can provide to system operation. The HP NetServer LPr is ideal for a clustered
environment, especially one where space is at a premium.
Servers are clustered, that is, physically connected and tightly integrated, so that the enterprise
business systems can achieve high availability with uptimes in excess of 99.9%. High
availability is attained through redundancy of software and hardware so that a single point of
failure will not interrupt service. These clusters are generally running mission-critical or
business-critical applications.
HP offers HP Assured Availability Solutions, a fully fault tolerant system that includes the HP
NetServer LPr. In partnership with Marathon Technologies, the HP Assured Availability Solution
provides uptimes in excess of 99.999%, which was essential to Paulo Products Company, a
metal processing firm. Paulo purchased two Assured Availability systems, one to run process
control software on the shop floor with 4 HP NetServer LPrs, and the second to manage their
database program with 2 LPrs and 2 HP NetServer LH 3s. Productivity has increased and
customer satisfaction has improved since implementation.
Consolidation
Server consolidation provides several benefits to the IT department and to the corporation.
Physical security is improved, system management and hardware resource utilization is more
efficient, staff workloads can be reduced or redirected and operating costs (especially hardware
support and OS licensing costs) frequently decline, in some cases by as much as 20%. The
space efficiency and cost-effectiveness of the HP NetServer LPr plus the cost-effectiveness of
the solution encourages centralization of a distributed system on densely racked server boxes.
A major mid-Western hospital purchased more than 40 HP NetServer LPrs, which were placed
in a central data center and used for consolidation of their server community. The
HP NetServer LPr provided the space savings that the hospital required.
