Multi-Tenant Sizing Requirements

Review Cortex XSOAR 6.14 multi-tenant sizing requirements for hosts and tenants, including production hardware recommendations.

Exact sizing specifications vary depending on several factors, including the number of incidents ingested, the number of indicators in the system, playbook usage, and so on.

Hardware Requirements

Each host and tenant is a standalone instance of the Cortex XSOAR server and must meet the minimum sizing recommendations for a production environment.

Component	Dev Environment Minimum	Production Minimum
CPU	8 CPU cores	16 CPU cores
Memory	16 GB RAM	32 GB RAM
Storage	500 GB SSD	1 TB SSD with minimum 3k dedicated IOPS

Example Multi-Tenant Deployment

This example details the sizing requirements for a single host that has two tenants.

The hardware requirements for this deployment are:

Component	Calculation	Production Requirements
CPU	(1 host plus 2 tenants) x 16 CPU cores	48 CPU cores
Memory	(1 host plus 2 tenants) x 32 GB RAM	96 GB RAM
Storage	Production Minimum	1 TB SSD with minimum 3k dedicated IOPS

Example Sizing Comparison Between Elasticsearch and BoltDB for Known Capacity

In this example where the number of incidents and commands is known, the sizing requirements for Elasticsearch and BoltDB are based on:

• approximately 50 incidents per day, per tenant, with each incident running 50 commands/scripts.
• For engines:

  • The specifications for each engine are 16 CPU and 32 GB RAM.
  • The engine is defined for each integration, including those that fetch incidents.
  • Incidents were fetched using the Splunk integration and executed using this playbook.

Database	Server CPU	Server Memory	Server IOPS	Number of Accounts w/ Engine	Number of Accounts w/o Engine
Elasticsearch	36 cores	72 GB	N/A	54	40
BoltDB	36 cores	72 GB	3000	52	32
