     1  # Resource Requirements
     2  
     3  A standard installation creates the following resources:
     4  
     5  - 1 Folder
     6  - 1 Tag Category
     7  - 1 Tag
     8  - Virtual machines:
     9    - 1 template
    10    - 1 temporary bootstrap node
    11    - 3 control-plane nodes
    12    - 3 compute machines
    13  
    14  ## Requirements
    15  
    16  ### Storage
    17  With the above resources, a standard installation requires a minimum of 800 GB of storage.
    18  
    19  ### DHCP
    20  Installation requires DHCP for the network. 
    21  
    22  ## Limits
    23  Available resources vary between clusters. The number of possible clusters within a vCenter will be primarily limited by storage space, plus any limitations upon the number of the resources limited above. Day Zero resources not provisioned by the installer, such as IP addresses and networks, should also be considered when planning.
