vSphere7 ESXi Virtual flash

[hazaki520]

After a fresh installation, it will generate about 120G of virtual flash in the system disk.Partition table appears as VMFSL.Can I turn it off?

Because I only have one hard disk, the virtual flash caused me poor and poor space.

This VMFSL is total disk size which is allocated for ESXi to install which can't be change or delete. Even, you can't resize the partition.If you are looking to use small size disk then you can use SD card with 16 GB or 32 GB for ESXi. If need more info contact to VMware support.

A great solution for me, works fine, enough for the ESXi free (hypervisor).
