VMware has released vSphere 5.5 (and other related product updates)
Duncan Epping has posted a list of all download links on his blog.
In this post I will provide a quick way to update your standalone ESXi host to ESXi 5.5
If your host is connected to the Internet then you just need to run the following commands in an ESXi shell:
# open firewall for outgoing http requests: esxcli network firewall ruleset set -e true -r httpClient # Install the ESXi 5.5 GA Imageprofile from the VMware Online depot esxcli software profile update -d https://hostupdate.vmware.com/software/VUM/PRODUCTION/main/vmw-depot-index.xml -p ESXi-5.5.0-1331820-standard
It might be very important to use update and not install here! More on this later. Reboot the host to complete the update.
