Why open source platform is the best platform
For the PACS servers?
Mehdi Saeedi, Dr. Afshin Niakan
EPD Co. Ltd.
At least there are 4 main reasons for selecting Open source platform
for the PACS and Dicom Servers
1-Security benefits
2-Reliability & scalability
3-Performance
4-Price

Security benefits
• Many developers cite transparency, as the main reason
open source software can be more robust than
proprietary systems. If customers and developers can
look at the code, they are more likely to find a bug and
create a patch.
• In a closed source model, customers must rely on the
vendors to identify, diagnose and issue a patch, which can
be a lengthy process.

Reliability & scalability
• Linux kernel components operated consistently and completed all
the expected durations of runs with zero critical system failures.
Linux system performance was not degraded during the long
duration of the run, the Linux kernel properly scaled to use
hardware resources (CPU, memory, disk) on SMP systems.
• the Linux system handled continuous full CPU load (over 99%) and
high memory stress well, and the Linux system handled overloaded
circumstances correctly.
• IBM declared that these tests demonstrate that “the Linux kernel
components are reliable and stable ... and can provide a robust,
enterprise-level environment for customers over long periods of
time.”.
• The Evolving Windows Vs. Linux Battle

Performance
• Linux with Samba surpassed Windows 2000 by about 100%
and can handle 4 times as many clients.
• PC Magazine published another comparison of Samba:
• The later Samba software surpasses the performance of Windows
2003 by about 100 percent under benchmark tests. Linux and
Samba can handle four times as many client systems as Windows
2003 before performance begins to drop off.

Windows vs. Linux Design
Windows Design
Viruses, Trojans and other malware make it onto Windows desktops
for a number of reasons familiar to Windows and foreign to Linux:
1. Windows has only recently evolved from a single-user design to a
multi-user model
2. Windows is monolithic, not modular, by design
3. Windows depends too heavily on an RPC model
4. Windows focuses on its familiar graphical desktop interface

Linux Design
1. Linux is based on a long history of well fleshed-out multi-user design
2. Linux is mostly modular by design
3. Linux does not depend upon RPC to function, and services are usually
configured not to use RPC by default
4. Linux servers are ideal for headless non-local administration

Price
For many reason we need to obtain licenses for our OS, databases,
and other products especially in the server side. Open sours dose
not mean free software, but they have a very low prices than the
commercial software.
