Recommended host configurations

Resource pool requirements

Zenoss recommends that all production deployments include a minimum of three hosts in two resource pools as follows:
  • One resource pool that contains the Control Center master host.
  • One resource pool that contains two delegate hosts for Resource Manager services.

CPU and memory requirements

The following table provides CPU and memory requirements for hosts in the types of Control Center resource pools that a typical Resource Manager deployment uses. For more information about pool types, see Key concepts. For more information about Control Center host requirements, refer to the Control Center Planning Guide.

Resource pool type Host requirements
Count Resources Comments
Master pool 1 4 CPU cores

16GB main memory

The amount of storage required for application data varies greatly.
Resource Manager pool 2+n 8 CPU cores

32GB main memory

To support failover or additional services, more than two hosts is preferred.
Collector pool n+1 4 CPU cores

8GB main memory

Collector services do not need DFS; remote pools can use higher connection timeout settings.
Single-host deployment: For a single-host deployment for testing or development work, Zenoss recommends a host with the following resources:
  • 8 CPU cores
  • 64GB main memory

Virtual hard disk requirements

During installation, for the master host, you will create seven virtual hard disks, and for each delegate host, four disks.

Master host disks:
  • One 30GB virtual hard disk on which to install the guest operating system. This disk must be attached to an IDE controller because a Hyper-V guest machine can only boot from an IDE drive.
  • Additional VHDX format, dynamically expanding disks sized as follows. These disks can be attached to any controller and in any location that will accommodate the disk.
    • two 50GB disks
    • one 150GB disk
    • one 200GB disk
    • two 16GB disks
Delegate host disks (each host):
  • One 30GB virtual hard disk on which to install the guest operating system. This disk must be attached to an IDE controller because a Hyper-V guest machine can only boot from an IDE drive.
  • Additional VHDX format, dynamically expanding disks sized as follows. These disks can be attached to any controller and in any location that will accommodate the disk.
    • one 50GB disks
    • two 16GB disks
