Arsitektur Server
Server
A system which provides certain services to
●
another system, manages the use of resources
for the service, and responsible for the
computing
- File server
- Print server
- Network server
- Database server
The “other system” can be in another computer
●
system, or in the same computer system
Server – Hardware Architecture
There is no “real” limit for a server's hardware
●
specification
Among all things, server is limited by microprocessor
●
performance
Usually a hard working server employs
●
multiprocessors to serve its tasks
Multiprocessor servers fall into one of two two major
●
classes:
a. Symmetrical Multiprocessor (Tightly coupled)
b. Loosely coupled
Server – HWA – Tightly Coupled
(SMP) Characteristics
A computer system with many processors
●
Each processor can access every resources of
●
the system (symmetrical)
Access is managed by one operating system,
●
which must support multiprocessors, memory
sharing and threads (ex. Windows Server 2003)
Creating a thread is running a different task for
●
the same process

Software Execution
Server – HWA – Loosely Coupled
Characteristics
A collection of computer systems with
●
resources, interconnected
Tasks are distributed among these collection of
●
hardware resources
