About controller considerations
SteelCentral Controller for SteelHead (SCC) and Client Accelerator Controller provide central management and reporting for multiple, separate deployments of acceleration products. You can run multiple virtual instances of these controller products on a single physical host, provided that the host has sufficient resources. The amount of resources the host virtual machine needs depends on the number of appliances you plan to manage through the controller.
You can access controllers through HTTP, HTTPS, or SSH. Access is configured through the controller’s Management Console.
SteelCentral Controller for SteelHead
Use the following table to determine the resources needed for SCC-v. Use the 64-bit SCC-v when managing more than 100 appliances.
For SteelHead management, each controller instance requires port 80 and port 443 inbound from the SteelHeads and port 22 outbound from each controller instance to managed appliances.
Maximum managed appliances | Minimum datastore size | Minimum RAM | Minimum CPU |
|---|
50 | 50 GB | 4 GB | 2 core, 2 GHz |
100 | 100 GB | 6 GB | 2 cores, 2 GHz |
250 | 250 GB | 6 GB | 2 cores, 2 GHz |
500 | 400 GB | 16 GB | 4 cores, 2.4 GHz |
1500 | 400 GB | 32 GB | 4 cores, 4 GHz |
Client Accelerator Controller
The table below lists the recommended resources for the indicated number of managed endpoints. By default, the controller is configured to support 100 endpoints.
The controller uses disk 1 for management and disk 2 for statistics.
When the size of disk 2 is increased to accommodate additional endpoints, the controller resizes it nondestructively; however, the contents of the disk are deleted if it’s size is decreased.
Maximum endpoints | Minimum RAM | Minimum disk 2 | Minimum CPU |
|---|
100 | 3 GB | 3 GB | 1 GHz |
1,000 | 3 GB | 15 GB | 1 GHz |
2,000 | 4 GB | 50 GB | 2 GHz |
4,000 | 6 GB | 100 GB | 2 GHz |
20,000 | 16 GB | 500 GB SSD | 9.2 GHz |
You need to have valid licenses installed on all managed appliances and endpoints. A missing base license on an appliance or endpoint can cause the health of the controller to become critical and temporarily invalidates other licenses on the controller.
