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.
Supported Remote Management Server Models and Firmware
Versions
You can use remote management applications to install or upgrade ESXi, or to manage hosts remotely.

Recommendations for Enhanced ESXi Performance
To enhance performance, install or upgrade ESXi on a robust system with more RAM than the minimum
required and with multiple physical disks.
For ESXi system requirements, see ESXi Hardware Requirements.
