Hardware Configuration

Most processes relating DICOM Viewer of SonicDICOM PACS is done on the server side where SonicDICOM PACS is installed.
It means you can expect overall performance will be improved by upgrading the hardware configuration of the server.

SSD/HDD

The followings are assumed that OS and SonicDICOM PACS is installed on C drive.

  1. Please change C drive to SSD.
  2. If possible, please set up RAID on C drive.
  3. Please add 2 internal HDDs and set them as store location of DICOM files (Data Path and Backup Path).

The configuration of SSD/HDD will be followings.

C: (OS, SonicDICOM PACS)
Y: (Data Path)
Z: (Backup Path)

Changing C drive to SSD improves a performance dramatically.
This is because SonicDICOM PACS frequently writes and reads the OS's temp folder.

Setting up RAID in C drive prevent that the system suddenly stops.
And this configuration enable you to avoid several potential problems.

By storing DICOM files in the added HDD, DICOM files will not be lost if C drive crashes.
Even if the added HDD crashes, there is another HDD. So it can reduce risk to lose DICOM files.
And if your Data Path (Y:) HDD crashes, you can immediately restore the system by changing Data Path to Backup Path (Z:) by using PACS Manager.

CPU

CPU's clock speed affects a speed of image processing.
The number of CPU cores affects response if there are simultaneous accesses from multiple Web browsers frequency, and if the hardware simultaneously communicates with multiple modalities.
SonicDICOM PACS supports image processing by multi-core CPUs, so the bigger CPU core makes performance of image processing significantly improved.

Memory

Memory affects performance if there are simultaneous accesses from multiple Web browsers frequency, and if the hardware has big stress by communication with multiple modalities.
