For Memory and CPU, the Resource Allocation Reservation on VMware is indicated in the table.
Hyperthreading is supported.
The OS disk requirement is fixed and logs are rotated to ensure that 10 GB is sufficient.
40 GB for an applications role node is a generous allocation and the size will not have to be
increased with the number of users.
The Database storage partition is sized to support 250 K users.
Database backups are compressed and the partition is sized to ensure that sufficient
space is available to support backup of 250 GB database.
.. note::
To change the TRANSACTION_LOG cap size to greater than 10GB at larger providers for operational reasons,
for example for diagnostics, the **voss db_collection_cap TRANSACTION_LOG <10-50GB>** command can be used
from the command line.

Refer to Database Commands in the Platform Guide for more details.
The resize operation will impact the usage on the size of the disk allocated for the
database (typically, 250GB is reserved upon installation). Consider a larger
database disk size allocation upon installation if a larger cap size is set.
The backup disk should be Thick Provisioned and Eager Zeroed for better performance immediately after installation.
Web Proxies are optional, but if Web Proxies are used, then they form part of the cluster to allow sharing of
static data and other content as needed (for example, themes).
To set up the disk requirements, the disk should be set up on the VMware GUI Resources tab where a disk can be created.
This task should be done after the OVA import but prior to the boot of the system.
