Sizing Assumptions Used For vSAN ESA ReadyNodeTM Profiles
ESXi Boot
Network
  • (Dual port NIC) recommended for redundancy.
Device Capacity
  • The capacity point is for guidance only. You can choose different capacity points as long as Node Capacity and Performance/Endurance classes are met.
Number of Storage Tier Devices
  • The number of Storage Tier devices has an impact on the performance of vSAN ESA.
  • We recommend configuring more for better performance
Design Considerations Used For vSAN ESA ReadyNodeTM Profiles
Class of SSDsThe class of SSD you choose has a direct impact on the performance of your overall system.
Device Protocol The ReadyNode is certified with particular device type (NVMe). You are not allowed to change the device type.
