Many installations use Tufin Appliances to run SecureTrack and/or SecureChange with SecureApp. In some situations it feels as if with each new version of TOS the performance becomes slower and slower while in parallel the load of the machine becomes higher - even if there is no change in the number of monitored devices, log volume or number of concurrent users.
Looking at older versions like e.g. 17-1, the requirements for SecureTrack and SecureChange on a machine were 4 processor cores and 4 GB RAM. Recommendation for productive environments were at least 4 processor cores and 8 to 12 GB RAM.
Since then many features have been added to Tufin Orchestration Suite, so the software package has become much bigger, e.g. 16-1 was about 750 MB, 17-1 was about 810 MB while 18-1 has grown up to approximately 1.4 GB. A possible reason are many new features that are added to the code. The size of the code has nearly doubled which in consequence leads to an increase of hardware requirements. These are today:
- CPU: 24 Cores
- RAM: 32 GB
- HD: 1 TB usable space in RAID
For a production environment recommended hardware is
- CPU: 32 Cores
- RAM: 64 GB
- HD: 2 TB usable space in RAID
Following these recommendations, a Tufin T-510 fulfills minimum requirements only. Even if this machine has been suitable for some environments about two or three years ago, it's currently recommended to use in productive environments the appliances T-1100 or T-1100XL only.
The load on a machine can be reduced using Tufin Distributed Architecture. In this configuration, Remote Collectors and Distribution Servers take load from the Central Server. Additional licenses are not required, only additional hardware.
The "real requirements" depend not only on the number of monitored devices, but also on the size and complexity of rule bases as well as the number of logs, concurrent users etc. Please consult your Tufin SE to get more detailed information about your individual hardware requirements.
