Accelerated lifecycle management in HCI systems

1. An information handling system comprising:

at least one processor; and

a memory;

wherein the information handling system is configured to perform an upgrade of a plurality of hosts of an information handling system cluster by:

determining a score for each host based on hardware metrics of each host, wherein the score is determined as a weighted sum of component scores including a network bandwidth component score, a central processing unit (CPU) performance component score, a memory size component score, and a cache disk component score;

based on the determined scores, selecting a first host for upgrading;

migrating virtual machines from the first host to one or more other hosts; and

causing the first host to perform the upgrade.

2. The information handling system of claim 1 , wherein the cluster is a hyper-converged infrastructure (HCI) cluster.

3. The information handling system of claim 1 , wherein the information handling system is a particular host of the cluster.

4. The information handling system of claim 3 , wherein the determining and the selecting are performing by a virtual machine executing on the particular host.

5. The information handling system of claim 1 , further configured to:

determine a revised score for each of a plurality of un-upgraded hosts based on the hardware metrics;

based on the revised scores, select a second host for upgrading; and

while the first host is performing the upgrade, migrate virtual machines from the second host to one or more other hosts.

6. The information handling system of claim 1 , wherein the upgrade comprises an upgrade of an operating system and at least one firmware component.

7. A computer-implemented method for performing an upgrade of a plurality of hosts of an information handling system cluster, the method comprising:

determining a score for each host based on hardware metrics of each host, wherein the score is determined as a weighted sum of component scores including a network bandwidth component score, a central processing unit (CPU) performance component score, a memory size component score, and a cache disk component score;

based on the determined scores, selecting a first host for upgrading;

migrating virtual machines from the first host to one or more other hosts; and

causing the first host to perform the upgrade.

8. The method of claim 7 , wherein the scores are determined such that a total number of virtual machine migrations occurring during the upgrade is minimized.

9. The method of claim 7 , wherein the information handling system is a particular host of the cluster.

10. The method of claim 9 , wherein the determining and the selecting are performing by a virtual machine executing on the particular host.

11. The method of claim 7 , further comprising:

determining a revised score for each of a plurality of un-upgraded hosts based on the hardware metrics;

based on the revised scores, selecting a second host for upgrading; and

while the first host is performing the upgrade, migrating virtual machines from the second host to one or more other hosts.

12. The method of claim 7 , wherein the upgrade comprises an upgrade of an operating system and at least one firmware component.

13. An article of manufacture comprising a non-transitory, computer-readable medium having computer-executable instructions thereon that are executable by a processor of an information handling system for performing an upgrade of a plurality of hosts of an information handling system cluster by:

determining a score for each host based on hardware metrics of each host, wherein the score is determined as a weighted sum of component scores including a network bandwidth component score, a central processing unit (CPU) performance component score, a memory size component score, and a cache disk component score;

based on the determined scores, selecting a first host for upgrading;

migrating virtual machines from the first host to one or more other hosts; and

causing the first host to perform the upgrade.

14. The article of claim 13 , wherein the cluster is a hyper-converged infrastructure (HCI) cluster.

15. The article of claim 13 , wherein the information handling system is a particular host of the cluster.

16. The article of claim 15 , wherein the determining and the selecting are performing by a virtual machine executing on the particular host.

17. The article of claim 13 , the instructions further executable for:

determining a revised score for each of a plurality of un-upgraded hosts based on the hardware metrics;

based on the revised scores, selecting a second host for upgrading; and

while the first host is performing the upgrade, migrating virtual machines from the second host to one or more other hosts.

18. The article of claim 13 , wherein the upgrade comprises an upgrade of an operating system and at least one firmware component.

19. The information handling system of claim 1 , wherein the component scores further include an additional component score that is configurable by a user.

20. The method of claim 7 , wherein the component scores further include an additional component score that is configurable by a user.
