Managing Computing Resources with a Name
Server
The SPD Server name server gives system administrators the ability to manage computing
resources without disturbing system users. The SPD Server name server maps logical
names that are referenced in SAS programs to the physical location of SPD Server tables.
Thus, a name server allows the system administrator to add, remove or reallocate disk space
and computing power without having to change SAS source code. Nor is there the necessity
of informing others about changes in resource allocation as long the name of the machine
that hosts the name service remains the same.
The following example demonstrates how to configure SPD Server to spread the processing
load across multiple machines in a network.
Configuring SPD Server on a Corporate Network
Inventory Available Corporate Network Servers
The example corporation maintains a network of computers. The corporate network
contains a mix of computers and processing power: there are machines with multiple
processors and large amounts of available disk space, smaller machines that are used for
servers, and desktop machines for client users. Among the dedicated servers, we find
worldcpu
a data store for the company's worldwide operations.
