Abstract

In a computer-implemented method for maintaining unallocated hosts of a pre-configured hyper-converged computing device at a baseline operating system version, a plurality of hosts of a pre-configured hyper-converged computing device is managed, where the plurality of hosts are allocable to workload domains, where the plurality of hosts each have an operating system version within a range of supported operating system versions, where unallocated hosts of the plurality of hosts are maintained within a pool of unallocated hosts, and where the unallocated hosts of the pool of unallocated hosts have a baseline operating system version of the range of supported operating system versions. A new unallocated host is received at the pre-configured hyper-converged computing device for inclusion to the pool of unallocated hosts. An operating system version of the new unallocated host is determined. Provided the new unallocated host has an operating system version other than the baseline operating system version, the new unallocated host is updated to the baseline operating system version. The new unallocated host is released to the pool of unallocated hosts for allocation to a workload domain.

First claim

What is claimed is:

1. A computer-implemented 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.

2. The computer-implemented method of claim 1 , further comprising:
receiving a command to remove a host from a particular workload domain, wherein the host removed from the particular workload domain is the new unallocated host.

3. The computer-implemented method of claim 1 , further comprising:
receiving a command to remove a particular workload domain from the pre-configured hyper-converged computing device, wherein a host of the particular workload domain is the new unallocated host.

4. The computer-implemented method of claim 1 , further comprising:
adding a new host to the plurality of hosts of the pre-configured hyper-converged computing device, wherein the new host is the new unallocated host.

5. The computer-implemented method of claim 1 , wherein the baseline operating system version of the range of supported operating system versions is an oldest version of the range of supported operating system versions.

6. The computer-implemented method of claim 1 , further comprising:
receiving a command to add an unallocated host of the pool of unallocated hosts to a particular workload domain;
determining an operating system version of hosts of the particular workload domain;
updating the operating system version of the unallocated host to the operating system version of allocated hosts of the particular workload domain; and
allocating the unallocated host to the particular workload domain.

7. The computer-implemented method of claim 6 , 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:
applying at least one patch to an operating system of the unallocated host for updating the operating system version of the unallocated host to the operating system version of the particular workload domain.

8. The computer-implemented method of claim 6 , 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.

9. The computer-implemented method of claim 6 , 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.

10. 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.

11. The non-transitory computer readable storage medium of claim 10 , further comprising:
receiving a command to remove a host from a particular workload domain, wherein the host removed from the particular workload domain is the new unallocated host.

12. The non-transitory computer readable storage medium of claim 10 , the method further comprising:
receiving a command to remove a particular workload domain from the pre-configured hyper-converged computing device, wherein a host of the particular workload domain is the new unallocated host.

13. The non-transitory computer readable storage medium of claim 10 , the method further comprising:
adding a new host to the plurality of hosts of the pre-configured hyper-converged computing device, wherein the new host is the new unallocated host.

14. The non-transitory computer readable storage medium of claim 10 , wherein the baseline operating system version of the range of supported operating system versions is an oldest version of the range of supported operating system versions.

15. The non-transitory computer readable storage medium of claim 10 , the method further comprising:
receiving a command to add an unallocated host of the pool of unallocated hosts to a particular workload domain;
determining an operating system version of hosts of the particular workload domain;
updating the operating system version of the unallocated host to the operating system version of allocated hosts of the particular workload domain; and
allocating the unallocated host to the particular workload domain.

16. The non-transitory computer readable storage medium of claim 15 , 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:
applying at least one patch to an operating system of the unallocated host for updating the operating system version of the unallocated host to the operating system version of the particular workload domain.

17. The non-transitory computer readable storage medium of claim 15 , 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 all
