Sizing and scalability considerations

To plan your BMC Digital Workplace deployment, use the recommendations in this topic.

The sizing guidelines for BMC Digital Workplace and BMC Remedy with Smart IT (Smart IT) together are provided in  Hardware requirements  in the BMC Remedy ITSM Deployment online documentation.

BMC Digital Workplace and Smart IT server cluster

To calculate the size of the environment required for BMC Digital Workplace, BMC uses the following factors:

  • Total number of users
  • Estimated concurrent connections (usually 10% of the total users)

BMC recommends that you have one BMC Digital Workplace and Smart IT server (with 4 GB and 2 CPUs) for 15,000 registered users, which includes an estimated 1,500 concurrent users. For each environment, consider one extra BMC Digital Workplace and Smart IT server to allow for rolling maintenance and handling of peak loads for events (such as a system outage).

To determine sizing for your environment, use the following formula:

(Total users X 10% / 1500) + 1 = Number of BMC Digital Workplace servers

For example, for 75,000 users, the formula would look like this:

(75000 users X 10% / 1500) + 1 = 5 + 1 = 6 BMC Digital Workplace servers

For the 2.6.00 release, the above formula applies up to total of 90000 users.

MongoDB cluster

The MongoDB cluster requires specific cluster setup to support high availability (HA). For the sizing recommendations for the small (1500 users), medium (4500 users) and large (7500 users) environments, use a replica set configuration of 1 primary and 2 secondary servers.

The sizing recommendations table below includes BMC recommendation for MongoDB cluster configuration based on the number of users.

Sizing recommendations

BMC recommends that you use one of the following deployment options for BMC Digital Workplace.
