Abstract
Disclosed is a storage system that includes a physical disk and a storage controller. The storage controller is configured to use a first physical link and a second physical link of a serial attached SCSI (SAS) wide port to communicate with the physical disk. Based on a dynamic system property, the storage controller is re-configured to use at least a third physical link of the SAS wide port to communicate with physical disk. Examples of the dynamic system property include load on the SAS wide port, a failure condition, or premium feature enablement.
Claims20
A method of operating a storage system, comprising:
- configuring a storage controller to use a first physical link and a second physical link of a serial attached SCSI (SAS) wide port to communicate with a physical disk;
- and,
- based on dynamic system property, configuring the storage controller to use a third physical link of the SAS wide port.
A storage system, comprising:
- a physical disk;
- and,
- a storage controller configured to use a first physical link and a second physical link of a serial attached SCSI (SAS) wide port to communicate with the physical disk, and configured to use a third physical link of the SAS wide port based on a dynamic system property.
A non-transitory computer readable medium having instructions stored thereon for operating a storage system that, when executed by a computer, at least instruct the computer to:
- use a first physical link and a second physical link of a serial attached SCSI (SAS) wide port to communicate with a physical disk;
- and,
- based on dynamic system property, use a third physical link of the SAS wide port.
