Universal CMDB 11.0 is supported on the following hardware:

Component Requirement


To fulfill the CPU requirements, you must have one of the following:

  • Intel Dual Core Xeon Processor 2.4 GHz or later
  • AMD Opteron Dual Core Processor 2.4 GHz or later

Recommended: The latest generation of Intel/AMD processors are recommended.

In addition to the above requirements, you must have the following number of CPU Cores, depending on your deployment configuration.

CPU Cores:

Deployment Minimum Recommended
Small 1 Core 4 Cores
Standard 4 Cores 8 Cores
Enterprise 8 Cores 24 Cores
Note: As Universal CMDB performance is dependent upon processor speed, to ensure proper Universal CMDB performance, it is recommended that you use the fastest possible processor speed.
Deployment Windows/Linux:
Minimum Recommended
Small 4 GB RAM 8 GB RAM
Standard 8 GB RAM 16 GB RAM
Enterprise 16 GB RAM 32 GB RAM (for more than 40 million CIs and relationships)
Memory Swap File

Windows: The virtual memory for Windows should be at least 1.5 times the size of the physical memory.

Linux: The Linux swap file size should be equal in size to the physical memory.

Free hard disk space
  • Small/Standard/Enterprise: At least 120 GB (for logs, memory dumps, and so on)
  • If the search functionality is enabled, more hard disk space is required.

    For example,

    • 14M CIs + relationships: 30G or more space would be needed for SOLR index files
    • 20M CIs + relationships: Almost 50G space would be needed

Note Support for Storage Area Network (SAN) is available for usable disk space for UCMDB. You can install UCMDB Server on Storage Area Network (SAN) disk storage attached to a server.

Display Windows: Color palette setting of at least 256 colors (recommended: 32,000 colors)
