Appendix C How to Estimate Database Usage

 Virtual machines

vCenter Server or ESX must be built to manage virtual machines.

About 9.0 KB is used for management of a virtual machine.

Use the following information as a guide of individual calculation.

vCenter Server 0.5 KB / unit

DataCenter 0.6 KB / unit

ESX 4.0 KB / unit

virtual machine 3.3 KB / unit

template 0.6 KB / unit

E.g.1)

When building vCenter Server * 1, DataCenter * 5, ESX * 50, a virtual machine *

1500, and a template* 300, necessary disk capacity is calculated to about 5.4 MB

according to the following formula.

Necessary disk capacity 5333.5 KB = 1 (the number of vCenter Server) * 0.5 KB

+5 (the number of DataCenter) * 0.6 KB

+ 50 (the number of ESX) * 4.0 KB

+1500 (the number of virtual machines) * 3.3 KB

+300 (the number of templates) * 0.6 KB.

If the numbers of NIC and memories to connect to the machine increase,

necessary disk capacity also increases.

 Logical settings

Logical settings include server groups, host definitions and IP address definitions.

Use the following information as a guide of individual calculation.

Server Group 1.5 KB / unit

Host Definition 0.7 KB / unit

IP address 0.4 KB / unit

E.g.1)

When creating a server group with 10 host definitions that are configured 1 IP

address for each, necessary disk capacity is calculated to about 12.5 KB.

E.g.2)

When creating 50 server groups with 500 host definitions of DHCP operations for

each, necessary disk capacity is calculated to about 17.5 MB.
