Rather than focusing on fielding a complete, coherent design, they need to prioritize their requirements and ensure that operational forces and sustaining institutions--the subsystems
of a national security system--develop in phase with one another.
In The Myth of Laziness, where he argues that people who appear lazy actually have "output failure," Levine says that the subsystems
supporting overt behavior are faulty.
In addition, the organization's subsystems
will be related to one another and to the external environment in various ways.
Divide the total price of the library, drives and media by the capacity (in gigabytes) of the tape library to determine the price per gigabyte for the working tape subsystem
In other words, the connectivity to all storage subsystems
, whether they are mainframe or open systems based, can be accomplished over a single common network infrastructure.
NT 2000, Linux, Netware, and Unix servers should be able to share the same storage subsystems
The use of device virtualization to substitute cheaper open systems devices or subsystems
for mainframe devices would probably be widespread if it weren't for the fact that mainframe device I/O controllers pose a few more business and technology problems than their open systems cousins.
must be capable of recovery from failure.
