Resource Manager virtual appliances
Zenoss Service Dynamics is available as a pair of virtual appliances, one for a Control Center master host, and another for Control Center delegate hosts. Control Center and Resource Manager are installed, the required Docker images are loaded into the local registry, and the latest supported version of CentOS is installed with all of the packages needed to begin using Resource Manager as quickly as possible. In addition, the components of Zenoss Service Impact and Zenoss Analytics that integrate with Resource Manager are included and ready for final configuration.
Virtual appliances are packaged as Open Virtual Appliance (OVA) and ISO disk image files, and their resource requirements vary by hypervisor (VMware vSphere or Microsoft Hyper-V) and role (Control Center master or delegate).
To download Zenoss Service Dynamics virtual appliance files, you need permission to gain access to delivery.zenoss.com. For more information, contact Zenoss Support.
Resource requirements for multi-host deployments
Zenoss strongly recommends a minimum of 3 hosts for all production deployments of Zenoss Service Dynamics. Most environments require more than 3 hosts. Development or testing deployments can be single-host deployments.
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 Resource Manager concepts.
| Resource pool type | Host count | Host 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. |
Control Center master host storage
The Control Center master host virtual machine requires a total of 7 virtual hard disks. The following table identifies the purpose and size of each disk.
| Purpose | Size |
|---|---|
Root (/) |
30GB |
| Swap | 16GB |
Temporary (/tmp) |
16GB |
| Docker data | 50GB |
| Control Center internal services data | 50GB |
| Application data | 200GB |
| Application data backups | 400GB |
On vSphere hypervisors, the disks are created when the OVA is installed. On Hyper-V hypervisors, the disks must be created manually.
Control Center delegate host storage
Control Center delegate host virtual machines requires a total of 4 virtual hard disks. The following table identifies the purpose and size of each disk.
| Purpose | Size |
|---|---|
Root (/) |
30GB |
| Swap | 16GB |
Temporary (/tmp) |
16GB |
| Docker data | 50GB |
On vSphere hypervisors, the disks are created when the OVA is installed. On Hyper-V hypervisors, the disks must be created manually.
Resource requirements for single-host deployments
A single-host deployment of the Zenoss Service Dynamics virtual appliance requires a virtual machine with a minimum of 8 CPU cores and 64GB of main memory.
The disk requirements are identical to the master host disk requirements for multi-host deployments. On vSphere hypervisors, the disks are created when the OVA is installed. On Hyper-V hypervisors, the disks must be created manually.
