New rules in Sizer for Regular Models and ROBO Models (October 2018)

Regular Models

Rules

• All models included
• All use cases are allowed – main cluster application, remote cluster application and remote snapshots
• 3+ nodes is recommended

Summary

• • This is default in Sizer and is used most of the time
  • Fits best practices for a data center to have 3 or more nodes
  • Huge benefit as Sizer user can stay in this mode to size for 1175s or other vendor’s small models  if they want 3+ nodes anyhow. No need to go to Robo mode

 

• Note: This gets rid of previous Sizer user headache as they want to size these models for 3+ nodes and get confused where to go

 

What changes

• The smaller nodes such as 1175S are included in the list for running main cluster applications vs just remote applications and remote snapshots

ROBO Models

Rules

• • All models  but only some can size for 1 or 2 node
  • All use cases – main cluster application, remote cluster application and remote snapshots
  • All models can 3+ nodes depending on sizing requirements

 

• ONLY Certain Models (aka ROBO models) can be 1 or 2 node

 

• • Note there is no CPU restriction.  Basically PM decides what models are ROBO and they can be 1 or 2 cpu

Summary

• User would ONLY need to go to ROBO if they feel the solution fits in 1 or 2 node
  • If the size of the workloads require 3+ nodes, Sizer would simply report the required nodes and it would be no different recommendation than in regular
  • They feel 1 or 2 node restrictions is fine.  
    • The list of robo models are fine for the customer
    • RF for 1 node is disk level not node level
    • Some workloads like AFS require 3 nodes and so not available

What changes

• All models can be used in ROBO where before it was just the ROBO models

No quoting in Sizer for Robo

Currently there are minimum number of units or deal size when quoting Robo.  Sizer will size the opportunity and will tell you that you should quote X units.  Given it takes 10 or more units and possibly you want to club together multiple projects, we disabled quoting from Sizer when includes 1175S
