xSeries 440 application solutions

The x440 is an ideal platform for customers running mission-critical applications.

There are a number of ways the x440 can be deployed in specific application

solution environments. These include:

Server consolidation

Enterprise applications

Infrastructure applications

2.1.1

Server consolidation

Server consolidation is a process of centralizing business computing workloads

to reduce cost, complexity, network traffic, management overhead and, in

general, to simplify the existing IT infrastructure and provide a foundation for new

solution investment and implementation.

Server consolidation is discussed in detail in 2.4,

“

page 51.

Server consolidation solutions can be divided into two groups: those where no

more than four-way SMP is needed, and those that will take advantage of more

CPUs.

Four-way configurations

The four-way configurations would most likely be good candidates for

traditional messaging/collaboration environments such as Microsoft

Exchange and Lotus Domino. These applications do not scale well beyond a

four-way SMP configuration. It is an optimal platform for customers who

intend to migrate from Exchange 5.5 to Exchange 2000 using new features of

Exchange 2000 such as the support for more databases. Many customers

have distributed Exchange and Lotus Domino sites, which is costly and

difficult to manage. Here, the x440 can be a very attractive platform to

consolidate distributed sites into a central site.

Many ISPs are running different Internet applications and mail systems on

several servers. In most cases, they run applications on several servers to get

better I/O. The four-way x440 server connected to an RXE-100 fulfills this

requirement and ISPs can continue servicing the customers by consolidating

to an x440 server.

Although many applications such as file, print, and terminal servers do not

scale well beyond two processors, the four-way x440 can be a good platform

on which to consolidate those distributed applications. For example, using
