datastore. Although a 1GB USB or SD device suffices for a minimal installation, you should use a 4GB or
larger device. The extra space is used for an expanded coredump partition on the USB/SD device. Use a
high-quality USB flash drive of 16 GB or larger so that the extra flash cells can prolong the life of the boot
media, but high-quality drives of 4 GB or larger are sufficient to hold the extended coredump partition.
See Knowledge Base article http://kb.vmware.com/kb/2004784.
In Auto Deploy installations, the installer attempts to allocate a scratch region on an available local disk or
datastore. If no local disk or datastore is found, /scratch is placed on ramdisk. You should
reconfigure /scratch to use a persistent datastore following the installation.
For environments that boot from a SAN or use Auto Deploy, you need not allocate a separate LUN for
each ESXi host. You can co-locate the scratch regions for many ESXi hosts onto a single LUN. The
number of hosts assigned to any single LUN should be weighed against the LUN size and the I/O
behavior of the virtual machines.
ESXi 6.7 Installation on M.2 and other Non-USB Low-end Flash Media
Unlike USB flash devices, the ESXi installer creates a VMFS datastore on M.2 and other non-USB low-
end flash media. If you deploy a virtual machine or migrate a virtual machine to this boot device
datastore, the boot device can be worn out quickly depending on the endurance of the flash device and
the characteristics of the workload. Even read-only workloads can cause problems on low-end flash
devices.
Important If you install ESXi on M.2 or other non-USB low-end flash media, delete the VMFS datastore
on the device immediately after installation. See vSphere Storage for more information on removing
VMFS datastores.
Supported Remote Management Server Models and Firmware
Versions
You can use remote management applications to install or upgrade ESXi, or to manage hosts remotely.
