      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.
