Did you know that Solaris Containers has the largest HCL of any server virtualization solution?

Here are three examples:

1. Solaris 10 HCL: 790 x86/x64 systems + 75 SPARC systems = 865 total systems (March 28, 2007)
2. VMware: 305 x86/x64 systems (March 21, 2007)
3. Xen publishes specific component requirements (e.g. "1.5GHz single CPU minimum") instead of an HCL

Note that the Solaris Containers functionality is available on all Solaris 10 systems, and is exactly the same on all hardware architectures.

Is that metric relevant? Many factors should affect your virtualization choice. One of them is hardware choice: "does my choice of server virtualization technology limit my choice of hardware platform?"

The data points above show sufficient choice in commodity hardware for most people, but Containers maximizes your choice, and only Containers is supported on multiple hardware architectures.
