Posted on

Sizer 5.0

Sizer 5.0 is the latest version of Sizer going live on 24 Feb 2021

Whats New?

Three major features in Sizer 5.0 :

1. Multi recommendation

Sizer to now have an option to recommend more than one solution for a given workload, depending on the price range.

2. Sizer Policy

These are the recommended cluster settings based on the deployment environment for the cluster being sized. Sizer strongly recommends to go with the default settings for the chosen environments , however, it allows you to make modifications to adjust to a given requirement.

3. Advanced Cluster settings

These are advanced filters to narrow down the sizings to a more specific solution, providing for greater flexibility and ability o accomodate specific customer requests.

 

Sizer journey to 5.0:

From single workload to multi workload to multi cluster to finally multi recommendation with Sizer 5.0

 

Multi-era  for Sizer: 

 

  • Multiple Workloads
      • Bulk Edits – Ability to update, delete, disable, enable many workloads at once
      • Enable our next move towards Collector-driven sizing where Collector feeds Sizer with 100s of workloads to create the  most precise sizing

 

  • Multiple Clusters
      • Cluster Settings – Ability for each cluster to have its own settings for common characteristics
        • CPU speed, NIC, Max nodes, thresholds, etc
        • This allows each cluster to be optimized for specific workloads
      • Sizer Policy – Apply best practices defined by experts for different environments
        • Settings for Test/Dev, Production or Mission Critical Environments

  • Multiple Recommendations

  • Cluster Settings gives the user control so Automatic Sizing gives desired recommendation
  • Multiple recommendations then allow user to play with the results
    • Cost Optimized, Compute Optimized, Storage Optimized solutions are provided
    • Each can be further tweaked by the user

 

Sizer 5.0 – Multiple Recommendations

 

Toggle between multiple recommendations that fit your cost tolerance

  • Cost Optimized – lowest cost-default option
  • Compute Optimized- most cores within cost tolerance
  • Storage Optimized – most HDD/SSD within cost tolerance

  • Cost Tolerance
  • This is advanced settings in cluster
  • Allows to select a price delta(from the cheapest)
  • Triggers multi recommendation within the price range

 

Sizer 5.0 – Policy

Why..

Different deployment environments might have different needs in terms of availability/resiliency and performance

What..

These are the recommended cluster settings based on the deployment environment. Brings consistency of sizings for a given environment.  

How.. 

Each cluster to have one of below policy

  • Test/Dev, Production, Mission Critical
  • Allowed to edit the policy settings 

Apply your own Sizer Policy for cluster characteristics

  • Maintenance Window requirements
  • Network speed
  • Minimum Compression
  • Other settings

Each cluster can then follow operational policy

  • Test/Dev, Production, Mission Critical
  • You can edit the policy to better meet customer needs

Sizer 5.0 – “Customize” the auto 

  • Tweak the auto recommendation through “Customize” option 
  • Allows incremental increase or decrease of the selected resource
  • Checks for valid /qualified combinations when tweaking( for ex: if tweak violates SSD/HDD rule or balanced memory config, won’t allow 
  • Shows the cost delta for the customized solution
  • Stay on the Solutions page while playing with options.

Sizer 5.0 – Advanced Cluster settings

Minimum CPU frequency:

  • This will ensure the sizing recommends only the processors above the quoted frequency
  • Helpful if customer is keen on certain range of processors for performance reasons 

CVM/node

  • The values here will override the default CVM overhead applied by Sizer -1
  • Allows customer to provision more cores/ram to CVM in case of performance sensitive workloads

Cost Tolerance

  • Allows for a price delta (from the lowest cost)
  • Recommends more than one(default) solution-2
  • Cost optimized :default-lowest cost solution
  • Compute optimized : most core heavy solution in the price range
  • Storage optimized: most capacity heavy solution in the  price range
