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. [ESM License Detail]

   

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.
