Linux deployment sizing

You must consider several core technologies when sizing a BMC Cloud Lifecycle Management environment. Sizing of each product in the value path is based on the individual load on each product's sample use case, as described in the following table. The following topics are covered in this section:

Sizing by deployment type

The following table explains the sizing requirements for each product in the solution.

Note

Some installations might have specific requirements and complexities that are not reflected here. You must account for these differences when designing a deployment. Compact Deployment is now only supported when upgrading to BMC Cloud Lifecycle Management 4.7.

Deployment type

Number of managed devices

Rate of Change (VM Create, Update, Retire)

Concurrent Cloud Admins

Concurrent Cloud End Users

Application tier hardware sizing

Note

The following table does not include sizing for Compact Deployment (25 Peak Concurrent Users , 5000 VMs). You use a single VM for Compact Deployment to minimize hardware requirements. The minimum requirement for Compact Deployment is 12 VCPU 2+GHz x1, 32 GB RAM, 120 GB Disk.

The table below describes the number of nodes needed for each deployment size.

Database Tier Hardware Sizing Information

Physical servers are required for the database servers.  We do not recommend running databases on virtualized hardware.

Customers may choose to host product databases on single physical server or on separate servers. The decision is based on multiple factors, including, but NOT limited to H/W and Licensing cost, performance, administration & maintenance efforts and security requirements.

Sizing for separate database servers

Note

The following table does not include sizing for Compact. You use a single database server for Compact Deployment to minimize hardware requirements.

If customers choose to host product databases on separate servers, see the sizing (and number of DB servers) mentioned below:

Note

  • The disk size mentioned above indicates disk space consumed by the data and indexes. Please include additional space for OS and other software installed. Below is approximate distribution between data and index space for reference purpose:
    • For BMC Server Automation database: 40% Data , 60% Index
    • For BMC Network Automation, Cloud DB and Enterprise AR server databases: 60% Data and 40% Index
  • Atrium Web Registry database is not very transactional in nature and hence much smaller in size.  For all Small and Medium deployments, this database can be installed on the same Oracle server instance.
  • The sizing above is based on benchmark tests for CLM specific use cases only
  • Transaction Log sizing is mainly driven by two factors. Customers should size transaction log files based these factors:
    • Database recovery model
    • DB backup strategy and frequency
