Management of a virtual machine in a virtualized computing environment based on a fabric limit
First Claim
1. An apparatus, comprising:
- a memory;
at least one processor; and
program code stored in the memory and configured upon execution by the at least one processor to manage virtualization in a computing environment of the type including one or more fabrics coupling a plurality of hosts to one or more storage systems, the program code configured to;
determine a fabric limit for a limited fabric resource of a first fabric among the one or more fabrics, wherein the limited fabric resource constrains a capacity of the fabric and the fabric limit comprises a limit on the limited fabric resource;
determine an allocation of the limited fabric resource for the first fabric wherein the allocation is associated with a current usage of the limited fabric resource; and
control placement of a virtual machine on a first host among the plurality of hosts using at least one processor based at least in part upon the determined fabric limit and determined allocation of the limited fabric resource for the first fabric such that the virtual machine is selectively deployed on the first host to access a storage system among the one or more storage systems using the first fabric during execution of the virtual machine on the first host;
wherein the limited fabric resource comprises a fabric login for a storage switch in the first fabric, and wherein the fabric limit comprises an active login limit of the storage switch.

Abstract
An apparatus and program product manage virtual machines in a virtualized computing environment based at least in part on limitations associated with storage fabrics through which virtual machines may access one or more storage systems in such an environment. The storage fabric limitations may be used, for example, in connection with placing virtual machines on hosts in a virtualized computing environment. As another example, storage fabric limitations may be used in connection with deploying virtual machines into a virtualized computing environment to reduce the likelihood of boot errors. As still another example, storage fabric limitations may be used in connection with load balancing across multiple fabrics in a virtualized computing environment.

5. A non-transitory computer readable medium comprising a computer program;
- and
program code stored on the non-transitory computer readable medium and configured upon execution by at least one processor to manage virtualization in a computing environment of the type including one or more fabrics coupling a plurality of hosts to one or more storage systems by; determining a fabric limit for a limited fabric resource of a first fabric among the one or more fabrics, wherein the limited fabric resource constrains a capacity of the fabric and the fabric limit comprises a limit on the limited fabric resource; determining an allocation of the limited fabric resource for the first fabric, wherein the allocation is associated with a current usage of the limited fabric resource; and controlling placement of a virtual machine on a first host among the plurality of hosts based at least in part upon the determined fabric limit and determined allocation of the limited fabric resource for the first fabric such that the virtual machine is selectively deployed on the first host to access a storage system among the one or more storage systems using the first fabric during execution of the virtual machine on the first host; wherein the limited fabric resource comprises a fabric login for a storage switch in the first fabric, and wherein the fabric limit comprises an active login limit of the storage switch. - View Dependent Claims (6, 7, 8)
