Maintaining unallocated hosts of a pre-configured hyper-converged computing device at a baseline operating system version

A non-transitory computer readable storage medium having computer readable program code stored thereon for causing a computer system to perform a method for maintaining unallocated hosts of a pre-configured hyper-converged computing device at a baseline operating system version, the method comprising:

• managing a plurality of hosts of the pre-configured hyper-converged computing device, wherein the plurality of hosts is allocable to workload domains, wherein the plurality of hosts each have an operating system version within a range of supported operating system versions, wherein unallocated hosts of the plurality of hosts are maintained within a pool of unallocated hosts, and wherein the unallocated hosts of the pool of unallocated hosts have a baseline operating system version of the range of supported operating system versions;
• receiving a new unallocated host at the pre-configured hyper-converged computing device for inclusion to the pool of unallocated hosts;
• determining an operating system version of the new unallocated host;
• provided the new unallocated host has an operating system version other than the baseline operating system version, updating the new unallocated host to the baseline operating system version;
• and
• releasing the new unallocated host to the pool of unallocated hosts for allocation to a workload domain.

A pre-configured hyper-converged computing device for supporting a virtualization infrastructure comprising:

• a plurality of hosts of a pre-configured hyper-converged computing device, wherein the plurality of hosts are allocable to workload domains, wherein the plurality of hosts each have an operating system version within a range of supported operating system versions;
• and
• a pre-configured software module supporting the virtualization infrastructure, the pre-configured software module is configured to:
• manage the workload domains;
• maintain a pool of unallocated hosts within the pre-configured hyper-converged computing device, wherein the unallocated hosts of the pool of unallocated hosts have a baseline operating system version of the range of supported operating system versions;
• receive a new unallocated host at the pre-configured hyper-converged computing device for inclusion to the pool of unallocated hosts;
• determine an operating system version of the new unallocated host;
• update the new unallocated host to the baseline operating system version provided the new unallocated host has an operating system version other than the baseline operating system version;
• and
• release the new unallocated host to the pool of unallocated hosts for allocation to a workload domain.
