Capacity Requirements

To use NSM efficiently, NSM recommends the following minimum requirements for the different platforms.

NSM 3.2.0 On-Premises requires minimum 270 GB of disk space for installation. For reporting and analytics data use the Reporting Disk Space Requirements (Data Storage + Cache)/SSD for sizes.

Management Only

Number of Firewalls	CPU (Cores)	RAM (GB)
100	4	16
150	4	16
250	8	16
500	8	16
750	8	16
1000	8	16
1000+	16	32

Management, Reporting and Analytics

Number of Firewalls	CPU (Cores)	RAM (GB)
100	4	24
150	4	24
250	8	24
500	8	32
750	8	32
1000	8	32
1000+	16	64

Reporting Disk Space Requirements (Data Storage + Cache)/SSD

Number of Firewalls	Data Retention 7 days	Data Retention 365 days
50	600 GB	750 GB
100	1.2 TB	1.5 TB
150	1.7 TB	2.3 TB
250	2.8 TB	4 TB

Distributed Deployments Sizing Guideline

Number of Firewalls	NSM Nodes
≤ 250	NSM Controller Node / Single Node Deployment
> 250	Controller Node + 1 Reporting Agent per 250 firewall
Reporting Agent resource requirements (CPU and RAM ) is the same as the controller node.
