## Introduction

This page presents the ESM farm capacity planning.

## Principles

1. SMAX
	1. Farm specific capacity for SMAX (Unit level)
		|  | Production only license threshold (premium + express) | Actions | Sizing |
		| --- | --- | --- | --- |
		| N/A | 0-2000 unit (0-1000 concurrent users, ie. cc) | No action. Starting from medium profile | Medium |
		| Alert 0 | 2000 unit (1000 cc) | Slightly changing pod sizing based on the inputs from RnD | Medium+ |
		| Alert 1 | 4000 unit (2000 cc) | Stop migrating in on-prem customers | Change profile to large |
		| Alert 2 | 4600 unit (2300 cc) | Stop migrating in on-prem customers and stop adding big customers |  |
		| **Alert 3** | **5200 unit (2600 cc)** | **Stop adding customers** |  |
		2. Sizing reference from SMAX
		| Suite Product | Tenants | Size |
		| --- | --- | --- |
		| SMAX | 100-400 | Small |
		| SMAX | 400-1000 | Medium\* |
		| SMAX | 1000-3000 | Large |
		\*Normally SMAX sizing starts from Medium as it comes with better HA planning
2. UCMDB
	1. Farm specific capacities are listed below
		| Suite Product | Max number of CI and Relationship | Size |
		| --- | --- | --- |
		| UCMDB | 10 million | Small |
		| UCMDB | 60 million | Medium |
		| UCMDB | 200 million | Large |
3. OO
	1. | Suite Product | Tenants | Size |
		| --- | --- | --- |
		| OO | 1-5 | Small |
		| OO | 6-20 | Medium |

## Examples

1. In a scenario with 4057 SMAX Premium license and 1005 SMAX Express license units.  
	The farm is close to out of capacity.
	Once the SMAX total prod license unit increase to 5200 units (current water mark 4057+1005=5062, 138 units to go), we need to stop adding customers.

2. Getting the UCMDB(CMS) Data Volume for a specific farm: \[CMS Data Volume\] PowerBI View.  
	39M means the volume is between small and medium.
