A few questions:
1. What is the best way to determine how much space ESXi is currently using when booting and run from an SD Card on a HP server with no local hard drive?
2. VMware says that 1GB minimum is required for installation of ESXi on a SD Card but 5.2GB is recommended for 6.5. We have a few ESXI hosts running at 5.5 that we're looking to upgrade to 6.5. Can this be done on the cards we're using? If not, how do we get from 5.5 to 6.5 on new cards? Will that require a fresh install/configuration or can the 4GB card be copied to a bigger card and then upgraded without interrupting existing the ESXI configuration?
