Developing Your Computer Hardware and Operating System Specification

In addition to the information that appears in the deployment architecture, you must specify the operating system that will be used on each computer used in your solution. You must also develop more information about the hardware. Your decisions will be based on your quality of service requirements, and represent your best guess at the hardware and operating system required to satisfy your qualify of service requirements.

For the example deployment architecture shown in Figure 2–1, the quality of service requirements were stated as:

To meet these quality of service requirements, the operating system and computer hardware specifications in Table 2–1 were developed.

Table 2–1 Computer Hardware/OS Specification for the Sample Deployment Architecture

Computer System	Hardware Model	Number of CPUs	RAM (in Gigabytes)	Number of Disks	Operating System
mscs01  mscs02	Sun Fire V440 Server	4	16	4	Solaris 9
commx01  commx02	Sun Fire V240 Server	2	4	2  4	Solaris 10
ds01  ds02	Sun Fire V240 Server	2	8	4	Solaris 10
am01  am02	Sun Fire V240 Server	2	8	4	Solaris 10
ms-mmp01  ms-mmp02	Sun Fire V240 Server	2	4	2	Solaris 10
ms-mtai01  ms-mtai02	Sun Fire V240 Server	2	4	2	Solaris 10
ms-mtao01  ms-mtao02	Sun Fire V240 Server	2	4	2	Solaris 10
ps01  ps02	Sun Fire V440 Server	4	16	4	Solaris 10
protect	Sun Fire V240	2	4	2	Solaris 10

You must develop similar information for the computer systems used in your solution.

Tip –

The Computer Hardware/OS specification is complete in itself. Once the specification is complete, the computer systems can be set up. Memory and disk drives can be installed, operating system can be installed, and the system made ready for installation of Java ES components.
