Sizing and scalability considerations

This topic provides BMC recommendations for planning your BMC MyIT Service Broker deployment:

MyIT Service Broker server

A typical server configuration consists of the following:

  • 4 CPU core
  • 16 GB RAM
  • 100 GB HDD

System database

The application platform requires a database in one of the following configurations:

  • Oracle 11.2.04+
  • MS SQL Server 2008 R2, 2012 R2, 2014 R2

Application and database hardware sizing

Proof of concept (POC)
50 concurrent users

Small

1 server:
4 CPU Core
16GB RAM
100 GB disk

One cluster:
8 CPU Core
16 GB RAM
200 GB disk

One cluster:
16 CPU Core
32 GB RAM
200 GB disk

One cluster:
32 CPU Core
64 GB RAM
200 GB disk

Note

These sizing estimates should be used as a starting point. You should conduct benchmarks in your environment, because sizing will vary depending on the specific workload mix, data volumes, and data composition.

Scalability

See note on Sizing and scalability in Multi-user workload test results.

High Availability

MyIT Service Broker can be run in a server group for high availability (HA) using a load balancer.

  • All MyIT Service Broker servers in a server group can provide catalog items to MyIT.
  • Only one MyIT Service Broker server can be used to manage the service catalog.

For instructions on setting up a server group, see Configuring MyIT Service Broker for high availability.
