Overview
As of NTA 4.4, flow data is stored in its own SQL database. This database may be co-located in the same SQL instance as your Orion database, provided that the SQL instance meets the minimum version requirements for both modules. Both Standard and Enterprise SQL editions are supported.
This article provides an example configuration that can be used as guidelines when deploying NTA and other Orion Platform products utilizing a SQL database for data storage onto one SQL server instance.
For recommendations on sizing, see What are the hardware recommendations for the NTA 4.4 SQL Flow Storage database? and the Multi-module system guidelines for the Orion Platform.
For a complete list of hardware and software recommendations for installing NTA and the NTA Flow Storage database, see the NTA System Requirements.

Resolution
The following scenario assumes you are deploying NPM, NTA, and Log Manager onto one SQL server instance.
The load was distributed among the Main Polling Engine and 1 Additional Polling Engine as follows:
- NPM: 24k elements
- NTA: 50k flows per second
- Log Manager: 1k syslogs per second sent to Main Polling Engine
The following hardware is recommended when deploying NPM, NTA, and LM onto one SQL server instance:
| SQL server version |
SQL Server 2016 SP1 or later Standard or Enterprise edition |
| CPU | 12-core Intel Xeon E5-4640V4 processor, 2.1 GHz or equivalent |
| Memory | 64 GB |
| Hard disk |
500 GB SSD drives The following should use separate physical disks to divide workload types and avoid bottlenecks:
