Introduction
This document is a configuration checklist for the Digital Workplace environment .
All recommendations should be taken as a starting point. BMC encourages customers to conduct their own testing based on their own workload and adjust the settings as necessary.

The BMC Digital WorkPlace (DWP) platform consists of the following servers:
- The DWP Catalog Server – the use cases provided by this server are web-based admin use cases for creating/modifying/maintaining the DWP catalog of available services
- The DWP Server – this web application provides the main web-based DWP use cases to the end users
- The ITSM AR Server – this server provides AR API services to the DWP Server and is not accessed directly by the end users
Alternatively, you can view the DWP platform as an additional application slayer or service on top of the standard BMC ITSM stack, providing the DWP use cases.
Deployment
The DWP use cases are web-based; consequently, a typical deployment would need to secure the web applications using standard techniques such as firewalls and HTTPS.
For clarity, the following diagram abstracts the essential of a standard DWP deployment, not including the security aspect as the security layer varies based on your network infrastructure.
Sizing and Benchmark
For simplicity, the sizing guideline is categorically partitioned into small/medium/large (S/M/L). If your sizing is borderline, you can conservatively size up. Alternatively, if sizing up is prohibitive, you can monitor resource usage after deployment to see if additional resources are needed.
The detail of the sizing benchmark environment, use cases, and workload is found here:
https://docs.bmc.com/docs/digitalworkplaceadvanced/1811/bmc-digital-workplace-catalog-test-environment-857514178.htmlThe essential hardware sizing and configurations are in the next section.
Sizing and Configuration Summary
The following tables provide guidelines for hardware sizing and essential configurations for each of the 3 servers described above. The sizing is based on S/M/L as detailed in the benchmark.
For quick reference:
- Small = 800 users
- Medium = 2,000 users
- Large = 5,000 users

Note: The above configurations are based on DWPA and DWPA Catalog workload only. If there is significant workload for ITSM in this same environment, adjust the settings to additionally account for the recommendations in the Best Practice Configuration Checklist for the ARSystem Platform and ITSM article. Please use the following
link. For example, if your ITSM environment requires its own 32 CPUs for the Database server (based on the size) and you are using a Large DWPA environment, you will need to adjust to 64 CPUs fore the Database Server.
