Introducing PXE Manager for vCenter

PXE Manager for vCenter enables ESXi host state (firmware) management and provisioning, Specifically, it allows:

  • Automated provisioning of new ESXi hosts stateless and stateful (no ESX)
  • ESXi host state (firmware) backup, restore, and archiving with retention
  • ESXi builds repository management (stateless and statefull)
  • ESXi Patch management
  • Multi vCenter support
  • Multi network support with agents (Linux CentOS virtual appliance will be available later)
  • Wake on Lan
  • Hosts memtest
  • vCenter plugin
  • Deploy directly to VMware Cloud Director
  • Deploy to Cisco UCS blades

What does that mean?  It automates the provisioning of ESXi hosts in either a stateless or stateful mode.  (notice no ESX support here!) via network boot using Pre-boot eXecution Environment (PXE)

How does that work?

Remember ESXi has a very small footprint--it's quite small that PXE booting ESXi is very easy.

Stateless and Stateful?

Stateful means the host keeps the "ESXi state" upon reboot--meaning the same version.  Think back to Microsoft RIS (remote installation services) days for VMware ESXi.

Stateless means the host doesn't keep the ESXi state upon reboot.  Why the heck would you want to do that you might ask?  I say why the heck wouldn't you want to do that?  Patching and upgrades becomes a breeze, throw a host into maintence mode--all the VMs evacuate to other hosts in the cluster then reboot the host.  When it comes up it's running the latest and greatest version of ESXi.  No extra leg work patching the host, it gets it automatically upon boot!  Think of the possibilities with DPM in the mix, a good amount of your environment can be automatically upgraded nightly when hosts get powered back on by DPM.

Provisioning

Provisioning becomes much easier--no need to install ESXi, and along with that the extra hardware required (SD Cards + Reader, Mirrored OS Drives, etc.)  Just rack new hardware and configure the BIOS for PXE boot and go!
