if i install the spp . all hardware drives will be update. for example nic,biosi firewall etc..
Yes, you can boot from the SPP either attached through iLO, or from an USB stick (USB creation Utility is included in the image). When you opt to run the interactive installation you the SPP will show you what it is going to install. Note that you cannot update the iLO firmware using the interactive installation when you attach the ISO image through iLO!
also is there a web site to check esxi 5.5 u3 and hardware update
Not exactly sure what exactly you have in mind. Anyway, the ESXi host shows some health information in the Configuration tab.
