IBM Spectrum Control 5.4.x - Memory, Processor, and Disk Space

Detailed System Requirements


What are the hardware requirements for IBM Spectrum Control™? How much memory, process and disk space do I need for managing my storage environment?





Microsoft Windows and Linux

Systems with minimum 4 or 8 processor cores:
  • Intel Xeon 4 processor cores - 2.5 GHz or greater
  • 2 Intel Xeon L5520 8 processor cores - 2.27 GHz or greater

  • POWER7
  • POWER8
  • POWER9 in POWER8 compatibility mode
  • POWER10 in POWER8 compatibility mode



In an evaluation environment with a limited number of volumes, storage systems, fabrics, switches, ports, and agents or agentless servers that are being monitored, you may not need 32 GB RAM, but at minimum 16 GB is required.

Disk space

25 GB of available disk space

25 GB of available disk space

If Red Hat Enterprise Linux is configured so that the above directories are individual file systems, each file system must have the following available space:

/usr 1 GB
/var 2 GB
/home 13 GB
/tmp 1 GB
/opt 10 GB

/usr - 1 GB
/var - 1 GB
/home - 13 GB
/tmp - 1 GB
/opt - 18 GB

Tip for all operating systems:  You do not need to manually create any subdirectories when you install IBM Spectrum Control.
Significant additional disk space of 40 - 80 GB is required for database and log files after data collection has started. The amount needed depends on the following factors:
  • The number of resources that are monitored
  • The length of time data is kept
  • How frequently data is collected
Refer to section 3.15 in the IBM Tivoli Storage Productivity Center Beyond the Basics publication for repository sizing formulas that can be used with IBM Spectrum Control.
Tip for VMware systems:  You may experience slow performance if IBM Spectrum Control is installed on a VMware virtual machine using a shared VMDK with other virtual machines.  When you use a shared VMDK (Virtual Machine Disk) it reduces the total number of disk IOPS (Input/Output Operations Per Second) available for each virtual machine; this causes poor performance and high disk latency on the virtual machine where you are running IBM Spectrum Control.  Use a dedicated VMDK for the VMware virtual machine where you are running IBM Spectrum Control. 


Cognos Analytics 11

Review the Cognos Analytics supported software environments:
  • For a single server installation of IBM Spectrum Control 5.4.1 with Cognos Analytics, running on Windows 2019 or RHEL 8, it is strongly suggested you use Db2 11.5.4 and Cognos Analytics 11.1.7, which both support Windows 2019 and RHEL 8.
  • Previous versions of Cognos Analytics 11.1 do not support Windows 2019 or RHEL 8.



Storage Resource Agents


Pentium 400 MHZ processor or higher


256 MB of RAM

Disk space

Approximately 350 MB of hard disk space
