Configuring the Service Console’s Processor Usage
To!review!and!configure!the!service!console’s!processor!usage,!click!the!CPU!tab.!
Figure 6-10. CPU tab
The!CPU!tab!shows!how!much!of!the!server!processor!or!processors!the!service!console!
is!utilizing!and!how!CPU!resources!are!allocated!to!the!service!console.
The!values!under!Resources!indicate!a!range!of!percentages!of!
a!processor!to!which!the!
service!console!is!entitled:
! Minimum!–!Minimum!amount!of!processor!capacity!that!is!always!available!to!the!
service!console.
! Maximum!–!Highest!amount!of!processor!capacity!the!service!console!can!ever!
consume,!even!if!the!processor!is!idle.!
! Shares!–!Relative!metric!for!allocating!processor!capacity,!where!this!value!is!
compared!to!the!sum!of!all!shares!of!all!virtual!machines!on!the!server!and!the!
service!console.
For!example,!a!virtual!machine!is!stored!on!the!same!drive!as!the!service!console!and!
has!a!minimum!CPU!percentage!
of!20%,!and!a!maximum!CPU!percentage!of!50%.!
Meanwhile,!the!service!console!has!a!minimum!percentage!of!30%!and!no!specified!
maximum!percentage.!You!can!give!the!virtual!machine!3000!CPU!shares!and!the!
service!console!1000!CPU!shares.
ESX!Server!interprets!this!allocation!so!that!the!virtual!machine!never!
has!less!than!20%!
of!the!total!physical!CPU!resources,!while!the!service!console!never!has!less!than!30%!
of!the!total!physical!CPU!resources.
If!other!virtual!machines!on!the!same!disk!are!idling,!ESX!Server!redistributes!this!extra!
CPU!time!proportionally,!based!on!the!virtual!machine’s!and!service!console’s!
CPU!
shares.!Active!virtual!machines!benefit!when!extra!resources!are!available.!In!this!
example,!the!virtual!machine!gets!three!times!as!much!CPU!time!as !the!service!console,!
subject!to!the!specified!CPU!percentages.!
