Hardware recommendations

The hardware required for a Novacura Flow installation depends on many factors, including the number of concurrent processes, the amount of data processed by the workflows, and the frequency of calls to third-party systems.

Memory

The amount of RAM used by the Flow Server or Web Client varies depending on usage. The software depends on RAM caches to speed frequent look-up operations; a high RAM for the server process is not necessarily a sign that more memory needs to be added.
Recommendation: 4 to 8 GB. (Up to 16 GB if Web Client and Server are installed on the same machine.)

Disk

A fast disk will speed up some operations in the Novacura Flow Server and Web Client. This is true, especially for workflows that handle large data sets or files. There may be some delay before disk space is freed, so it is normal to see a build-up of disk space usage in the initial stage of Novacura Flow Server usage.
Recommendation: 20+ GB of disk space available.

CPU

The Novacura Flow Server and Web Client are hosted in Microsoft IIS, making use of its threading and process model. Performance scalability is improved as clock speeds and the number of cores increase.
Recommendation: At least 2 GHz clock speed, at least 4 cores (8 if Web Client and Server are installed on the same machine).

License requirements

The address https://home.novacuraflow.com need to be reachable from the machine where the Novacura Flow is installed, so the Novacura Flow service can call home and check if the license is valid. If it is not possible to open up for https://home.novacuraflow.com, the license will need to be manually updated through the Novacura Flow studio every month.

All devices require at least version 6.7.10.1010 or higher of Zebra EMDKSERVICE on the device. Lower versions of EMDKSERVICE than this have limited scanning usability. Also note that Novacura Flow Android Client requires Android Lollipop or higher, which means supported Android KitKat devices will work with other scanning but will not run Novacura Flow client.
From version 6.10 for Zebra, the Data Wedge is used to control and execute scanning.
If upgrading to 6.10 and using the flow client preferences for scanner-specific settings, please note that these must be moved to the data wedge application.
