![]() With the new partition schema in vSphere 7.x, only the system boot partition is fixed at 100 MB. Therefore, the need for a more reliable, flexible, and high-performing system storage device for system storage is a necessity. Looking forward, the need for ESXi hosts to support other VMware or 3rd party solutions is ever-increasing. This restricted the support for installing large modules, debugging functionality, and possible third-party components. There were constraints on using multiple solutions with the 6.x partition sizes, for example, if you started to combine NSX-T, vSAN, Tanzu, vGPU etc. Before vSphere 7, partition management was limited in that both partition sizes were fixed and the partition numbers were static. This blog post will outline what we've seen in detail and provide the technical guidance to mitigate such issues.īefore getting into the details, it is crucial to understand the new system layout. We are now witnessing boot-related problems more frequently with ESXi 7.x with the hosts using SD cards or USB drives as boot media. SD cards and USB drives may also exhibit performance issues and may not tolerate high-frequency read-write operations. Such devices, however, have lower endurance and exhibit reliability and issues over time. ![]() ![]() Historically, SD cards or USB devices have been chosen to free up device bays and lower the cost of installing ESXi hosts. ![]()
