Title
Recommended Virtual Appliance Configuration for Scalability -
Description
The KACE SMA is configured, by default, to utilize 2 vCPUs and 8 GB of RAM (this is also the minimum system requirement for the SMA). However, this minimum specification is only designed for the average customer up to 2000 managed devices. For larger implementations, more resources are required. -
Resolution
The chart below lists the recommended vCPU, RAM, and NIC specifications based on managed device count (i.e. client systems with a SMA agent installed). This is only a general guideline, as the results can vary widely based on how the SMA is configured. It is possible to have less than 2000 managed devices, for example, and require more than 8 GB of RAM. Details about the SMA's performance are available in Settings | Logs, | System Performance (Needs to be enabled first on Settings | Security Settings | Enable Munin access).
With the release of SMA 13.0, the minimum amount of RAM was increased to 8GB, and subsequent tiers were increased 4GB to accommodate for new features and enhancements that have been added throughout the years. An upgrade attempt without 8GB will result on the upgrade aborting back to its previous state, with the upgrade logs mentioning the 8GB requirement.
Managed Device Count Recommended VM Resources Network Interface 0 - 2000 2 vCPUs & 8 GB RAM 1 Gigabit Ethernet 2000 - 4000 4 vCPUs & 12 GB RAM 1 Gigabit Ethernet 4000 - 8000 8 vCPUs & 20 GB RAM 1 Gigabit Ethernet 8000 - 16000 16 vCPUs & 36 GB RAM 10 Gigabit Ethernet 16000 - 32000 32 vCPUs & 68 GB RAM 10 Gigabit Ethernet 32000 - 50000 64 vCPUs & 132GB RAM 10 Gigabit Ethernet NOTE: These are minimum specifications in a simple configuration. Any changes that typically increase the use of system resources, such as complex Smart Labels, non-default check-in schedules, changes to history logging, and so on, require additional system resources.
It is certainly possible to have greater than 50000 managed devices and balancing the resources can be a bit more complex. Please contact KACE Sales for questions regarding new implementations of greater than 50000 managed devices. For existing customers, please contact KACE Support with any questions regarding scalability.
