Minimal server-side requirements of MedDream DICOM Viewer are as below:

Minimal hardware requirements:

*Equivalent of 5th generation Intel i5 2GHz CPU core (Q1’15 or later). For Virtual Machines: each virtual CPU appears as a single CPU core to the guest operating system. We recommend no more than one virtual CPU per physical core, or if hyperthreading supported, no more than two virtual CPUs per physical core. Oblique (3D) functionality requires one additional core per connection.

**Additional RAM memory must be reserved for OS, Database, PACS and/or other services if installed in the same machine.

***HDD used for software (fixed 1 GB size) and temporary data cache (see cache management description). HDD performance (used for caching) directly affects image open speed (SDD, RAM or HI speed disk storage recommended).

****Network bandwidth will directly affect image open speed.

NOTE:  Minimal hardware requirements depend on number of concurrent users, workload and image types. It is recommended to allocate 20-80% more resources for unusual work load or specific data types.
