Zoning data to a virtual machine

摘要

In a method to zone data to a virtual machine, support information is exchanged between a physical controller and an expander, the support information comprising an indication of an ability of the physical controller and the expander to support thereon a set of virtual controllers and a set of virtual physical layers (virtual PHYs), respectively. In response to a positive indication sending a list of SAS addresses to the expander, a list of SAS addresses is sent to the expander. Then, a first SAS address of the list of SAS addresses is assigned to a first virtual PHY of the set of virtual PHYs, wherein the assigning is performed by the expander, and wherein the first virtual PHY at an assigned SAS address corresponds to a first virtual controller of the set of virtual controllers.

主权项

1. A non-transitory computer-readable storage medium comprising instructions stored thereon which, when executed by a computer system, cause said computer system to:
exchange support information between a physical controller and an expander, said physical controller being coupled with a server and said expander being coupled with a Serial Attached Small Computer System Interface (SAS) switch, said support information comprising an indication of an ability of said physical controller to support thereon a set of virtual controllers and an indication of an ability of said expander to support thereon a set of virtual PHYs; in response to the indication of said ability of said expander to support thereon the set of virtual PHYs, send a list of SAS addresses to said expander from said physical controller, said SAS addresses of said list of SAS addresses representing virtual controllers of said set of virtual controllers; receive zoning instructions at said expander via a graphical user interface, said zoning instructions comprising at least one virtual PHY to physical controller mapping direction; and assign a first SAS address of said list of SAS addresses to a first virtual PHY of said set of virtual PHYs by said expander based upon said zoning instructions, said first virtual PHY at an assigned SAS address corresponding to a first virtual controller of said set of virtual controllers.
