    Multi-Tenant Sizing Requirements

    Sizing requirements for a Cortex XSOAR multi-tenant deployment depend on the number of hosts and tenants deployed.
    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.
    Cortex XSOAR Server Requirements

    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:

    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.
