Supports New API Endpoint - VMware Cloud Sizer V5 with total based sizing framework 

VMware Cloud Sizer V5 API takes VM level information as input and produces VMware Cloud sizing recommendation consisting of SDDC topology. 

  • New API access requires Cloud Service Provider (CSP) authentication.  
  • Total based sizing is based on input workload characteristics
  • Workload eligibility assessment to filter out outliers 
  • Target cloud recommendation with SDDC topology
  • Supports data import formats from discovery tools like vRealize Operations, Live Optics and RV Tools.

Partners can now invoke this API for tighter integration with the VMware Cloud Sizer and consume the recommended hosts and resources required for their workloads. For more information, see https://developer.vmware.com/docs/vmc-sizer/latest/.

November 19, 2020 (VMC Sizer and TCO Version 4.0)

  • Re-designed User Interface
    The VMC Sizer UI has been completely re-designed with a modern look and feel, making it more streamlined and easier to use.

  • Sizing Modes
    The VMC Sizer now supports three sizing modes:
    1. Quick Sizer: Perform sizing with minimal inputs.
    2. Import Mode: Perform sizing using data imported from on-premises using LiveOptics or RVTools.
    3. Advanced Sizer: Perform sizing using multiple workload profiles with more gradual configuration inputs.
  • Detailed Recommendation
    The VMC Sizer provides detailed sizing recommendations with a simplified view that can be expanded to include more details.

  • Instance Type Comparison
    Quickly switch between recommendations for different instance types (e.g. i3, i3en).

  • Re-designed PDF Download Report
    The PDF Download Report has been re-designed to make it easier to read, understand and present.

  • Sizing Improvements
    Numerous sizing improvements and fixes to the sizing algorithm.

July 21, 2020 (VMC Sizer and TCO Version 3.2)

  • LiveOptics and RVTools file import
    The VMC Sizer now supports importing sizing input data from LiveOptics and RVTools output files. This reduces the need to manually input data.

  • Large SDDC support
    Users can now choose to size for Large SDDCs. Large SDDCs require more resources than the default Regular size SDDCs.

  • Improved responsiveness support
    600x512 responsiveness support.

May 29th, 2020 (VMC Sizer and TCO Version 3.1)

  • i3en instance type
    The VMC Sizer now supports i3en instance sizing. This change ONLY applies to the VMC Sizer.

  • Removal of r5 instance type
    The VMC Sizer no longer supports the r5 instance type. This change ONLY applies to the VMC Sizer.

April 20th, 2020 (VMC Sizer and TCO Version 3.0)

  • 2 node cluster support
    Added support for sizing 2 node clusters. 

  • Stretched Clusters SLA compliance change
    Stretched Clusters now default to FTT=1 and RAID=RAID-5 for all cluster sizes when the users select auto mode. This change matches a recent update to the SLA that no longer requires FTT=2 and RAID-6 for Stretched Clusters with 12 or more hosts. 

  • Link to online TCO tool
    Users have the option to build their own TCO model by clicking on a button that takes them to a new self-service TCO tool.

  • Calculation improvements
    Some calculation improvements are added, including the ability to accept a decimal value for the vCPU/VM input.
  • UI improvements
    UI improvements, such as including units for some of the main input fields like Memory Utilization and CPU headroom.

December 17th, 2018 (VMC Sizer and TCO Version v1.1)

  • R5 instance type support
    Added support for EC2 R5 instance types and the ability to specify the amount of capacity used by Elastic vSAN.

  • User Interface improvements
    This update contains a number of improvements to the user interface including:

    • Moved the Cluster Settings modal window to the main view.
    • Moved the  Advanced Settings modal window to the main view.
    • Improved Workload Profile page experience. For example, it is now possible to rename Workload Profiles.
    • Other enhancements and stability improvements.
  • Target RAM Ratio
    The user can now specify the Target RAM Ratio to specify the maximum RAM overcommit.

  • Versioning support
    The VMC Sizer now includes a version number. This lets users know if an older recommendation that they downloaded used a different version of the VMC Sizer.

  • Auto modes for Host failures to tolerate and Fault Tolerance Method
    Users have the choice of setting HFT and FTM to specific values or letting the VMC Sizer automatically determine the settings that will minimize the number of hosts in the recommendation while also complying with the VMC SLA requirements. For example, clusters with 6 or more hosts must have HFT set to 2 according to the VMC SLA. In auto mode with 6 or more hosts in a cluster, the VMC Sizer will set HFT to 2 in order to comply with the VMC SLA and will minimize the storage overhead and number of recommended hosts by selecting RAID-6 for FTM.

  • Enhanced stretched cluster support
    The Stretched Cluster setting is moved to the main input view. The calculation logic for Stretched Clusters was also improved to provide more accurate recommendations.

  • Improved integration of the VMC Sizer and TCO tool
    Two main improvements are included in this release. First, a login is no longer required to access the TCO tool. Second, the VMC Sizer recommendation output feeds into the TCO tool input. This makes it easier for users to compare total cost of ownership based on the VMC Sizer recommendation.

  • Sizing calculation logic improvements
    The VMC Sizer calculator and logic were significantly improved for more accurate recommendations. In addition, this update addresses a number of stability issues.
