In a centralized environment, especially at peak business periods, the processing demand
can put heavy loads on the server. The HP NetServer LXr 8500 is a logical choice for a
centralized server system.
In both cases the processing demands of the application and the power and capacity of the
server hardware along with the network fabric limit the number of users that can be
supported. As compute or data access demands increase, many companies feel the
pressure for additional hardware. In other cases, the number of application or database
servers causes a system management headache. The LXr 8500 8-way capable SMP
system offers a viable solution for reducing complexity.
Client/server configurations for front-end application servers can be easily scaled by
segmenting the applications. Scaling is also accomplished by assigning functions to
dedicated servers depending upon the anticipated loads. Back-end database server
configurations may be either single machines with multiple databases or multiple machines
with single databases, again depending upon the size of the environment and service level
requirements. In a data center environment, both types of servers are typically rack-
mounted, symmetric multiple processor (SMP) machines.
Application servers require large amounts of memory but typically have minimal mass-
storage needs. Database servers are sometimes configured as high availability clusters,
providing insurance against a single point of failures. Both types of servers require rapid
I/O performance (network and mass storage), necessary for access to the databases.
