Abstract

In a computer-implemented method for provisioning a host of a workload domain of a pre-configured hyper-converged computing device, a pre-configured hyper-converged computing device comprising a plurality of hosts is managed, where the plurality of hosts is allocable to workload domains, and where allocated hosts of a particular workload domain are of a same operating system version. A pool of unallocated hosts is maintained within the pre-configured hyper-converged computing device, where the unallocated hosts of the pool have operating system versions within a range of supported operating system versions.

First claim

What is claimed is:

1. A computer-implemented method for provisioning a host of a workload domain of a pre-configured hyper-converged computing device, the method comprising:
managing a pre-configured hyper-converged computing device comprising a plurality of hosts, wherein the plurality of hosts is allocable to workload domains, and wherein allocated hosts of a particular workload domain are of a same operating system version;
maintaining a pool of unallocated hosts within the pre-configured hyper-converged computing device, wherein the unallocated hosts of the pool have operating system versions within a range of supported operating system versions;
responsive to receiving a command to add a host to the particular workload domain, provided the pool of unallocated hosts does not comprise a host that has the same operating system version as the allocated hosts of the particular workload domain, selecting an unallocated host from the pool of unallocated hosts;
updating the operating system version of the unallocated host to the operating system version of the allocated hosts of the particular workload domain; and
allocating the unallocated host that has the same operating system version as the allocated hosts of the particular workload domain to the particular workload domain.

2. The computer-implemented method of claim 1 , further comprising:
responsive to receiving a command to add a host to the particular workload domain, selecting a host from the pool of unallocated hosts that has the same operating system version as the allocated hosts of the particular workload domain; and
allocating the host that has the same operating system version as the allocated hosts of the particular workload domain to the particular workload domain.

3. The computer-implemented method of claim 1 , wherein the selecting an unallocated host from the pool of unallocated hosts comprises:
selecting an unallocated host from the pool of unallocated hosts having an oldest operating system version.

4. The computer-implemented method of claim 1 , wherein the updating the operating system version of the unallocated host to the operating system version of the allocated hosts of the particular workload domain comprises:
retrieving the operating system version of the allocated hosts of the particular workload domain from an operating system version repository; and
applying the operating system version retrieved from the operating system version repository to the unallocated host.

5. The computer-implemented method of claim 1 , wherein the updating the operating system version of the unallocated host to the operating system version of the allocated hosts of the particular workload domain comprises:
reimaging the unallocated host to the operating system version of the allocated hosts of the particular workload domain.

6. The computer-implemented method of claim 1 , further comprising:
responsive to receiving a command to remove a host from the particular workload domain, releasing the host to the pool of unallocated hosts.

7. A non-transitory computer readable storage medium having computer readable program code stored thereon for causing a computer system to perform a method for provisioning a host of a workload domain of a pre-configured hyper-converged computing device, the method comprising:
managing a pre-configured hyper-converged computing device comprising a plurality of hosts, wherein the plurality of hosts is allocable to workload domains, and wherein allocated hosts of a particular workload domain are of a same operating system version;
maintaining a pool of unallocated hosts within the pre-configured hyper-converged computing device, wherein the unallocated hosts of the pool have operating system versions within a range of supported operating system versions;
responsive to receiving a command to add a host to the particular workload domain, provided the pool of unallocated hosts does not comprise a host that has the same operating system version as the allocated hosts of the particular workload domain, selecting an unallocated host from the pool of unallocated hosts;
updating the operating system version of the unallocated host to the operating system version of the allocated hosts of the particular workload domain; and
allocating the unallocated host that has the same operating system version as the allocated hosts of the particular workload domain to the particular workload domain.

8. The non-transitory computer readable storage medium of claim 7 , the method further comprising:
responsive to receiving a command to add a host to the particular workload domain, selecting a host from the pool of unallocated hosts that has the same operating system version as the allocated hosts of the particular workload domain; and
allocating the host that has the same operating system version as the allocated hosts of the particular workload domain to the particular workload domain.

9. The non-transitory computer readable storage medium of claim 7 , wherein the selecting an unallocated host from the pool of unallocated hosts comprises:
selecting an unallocated host from the pool of unallocated hosts having an oldest operating system version.

10. The non-transitory computer readable storage medium of claim 7 , wherein the updating the operating system version of the unallocated host to the operating system version of the allocated hosts of the particular workload domain comprises:
retrieving the operating system version of the allocated hosts of the particular workload domain from an operating system version repository; and
applying the operating system version retrieved from the operating system version repository to the unallocated host.

11. The non-transitory computer readable storage medium of claim 7 , wherein the updating the operating system version of the unallocated host to the operating system version of the allocated hosts of the particular workload domain comprises:
reimaging the unallocated host to the operating system version of the allocated hosts of the particular workload domain.

12. The non-transitory computer readable storage medium of claim 7 , the method further comprising:
responsive to receiving a command to remove a host from the particular workload domain, releasing the host to the pool of unallocated hosts.

13. A pre-configured hyper-converged computing device for supporting a virtualization infrastructure comprising:
a plurality of hosts, each host comprising a processor and a hardware memory device, wherein each host of the plurality of hosts has an operating system version, wherein the plurality of hosts is allocable to workload domains, and wherein allocated hosts of a particular workload domain are of a same operating system version; 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 have operating system versions within a range of supported operating system versions;
provided the pool of unallocated hosts does not comprise a host that has the same operating system version as the allocated hosts of the particular workload domain, select an unallocated host from the pool of unallocated hosts in response to receiving a command to add a host to the particular workload domain;
update the operating system version of the unallocated host to the operating system version of the allocated hosts of the particular workload domain; and
allocate the unallocated host that has the same operating
