Hi Umesh,
An easier option would be to point all three VC's to the same SSO server and just use the Web Client which will give you a single pane view of all three servers.
This has the benefits of giving you a single pane view of all three servers without the need of worrying about single site/multi site/Multi site HA and manually relicating data etc
The only drawback would be to have to use the Web Client but considering that the vSphere Client is end of life anyways, should not really matter in the log run
Regards
