20120254553 | ZONE GROUP REASSIGNMENT USING STORAGE DEVICE SIGNATURES - A method and apparatus for assigning zone groups to a storage enclosure is disclosed. When a storage enclosure is added to a switch in a fabric, a signature of the storage enclosure will be created from the storage devices loaded in that enclosure. The signature will then be compared against the signature from a storage enclosure that is offline. When the signature matches the signature of the offline storage enclosure, the zone groups from the offline storage enclosure will be copied to the storage enclosure that was added to the fabric. | 10-04-2012 |
20120271996 | MEMORY RESOURCE PROVISIONING USING SAS ZONING - An example method for memory resource provisioning using SAS zoning can include a serial attached Small Computer System Interface (SCSI) (SAS) switch and a provisioning manager (PM) executing on the SAS switch. A plurality of servers are communicatively coupled to the SAS switch, each server executing an operating system (OS) having access to one or more OS volumes. A host provisioning agent (HPA) executes on the OS of each of the plurality of servers. A plurality of memory resources are communicatively coupled to the SAS switch. Each memory resource can have a number of physical hard drives. A first portion of the memory resources is associated with zone groups corresponding to the plurality of servers. A second portion of the memory resources is associated with a provisioning zone group (PZG) hidden from the plurality of servers but available to the PM. | 10-25-2012 |
20120284435 | ZONE GROUP MANAGER VIRTUAL PHY - A switch is provided. The switch includes an expander configured to couple a server to a set of storage drive bays. The switch also includes a zone manager coupled to the expander and configured to maintain a zoning configuration corresponding to the set of storage drive bays. The zone manager is coupled to the expander through a virtual PHY. | 11-08-2012 |
20120297052 | DETERMINING MISCONNECTION OF AN ELECTRONIC DEVICE TO A NETWORK DEVICE USING ZONE INFORMATION - Connection of an electronic device to a particular port of the network device is detected. It is determined based on zone information whether a misconnection has occurred. The zone information defines plural zones. | 11-22-2012 |
20130219393 | ZONING DATA TO A VIRTUAL MACHINE - 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. | 08-22-2013 |
20130246863 | CHANGE MESSAGE BROADCAST ERROR DETECTION - A hardware device detects change messages broadcast within a system. The system includes the hardware device, one or more controller devices, one or more expander devices, and one or more target devices interconnected among one another. The hardware device determines whether the change messages were broadcast within the system every first period of time or less for at least a second period of time, the first period of time less than the second period of time. In response to determining that the change messages were broadcast within the system every first period of time or less for at least the second period of time, the hardware devices signals that an error has been detected. | 09-19-2013 |
20140122751 | STORAGE ENCLOSURE BRIDGE DETECTION - A method for detecting an improper storage system configuration is provided. The method includes receiving, within a first switch, an indication of a configuration change of a storage system. The method also includes performing device discovery to identify devices operatively coupled to the first switch. The method also includes receiving a storage device identifier of a storage device operatively coupled to the first switch. The method also includes searching a repository for the storage device identifier to determine whether the storage device is managed by a second switch. | 05-01-2014 |
20150242265 | CHANGE MESSAGE BROADCAST ERROR DETECTION - A hardware device detects change messages broadcast within a system. The system includes the hardware device, one or more controller devices, one or more expander devices, and one or more target devices interconnected among one another. The hardware device determines whether the change messages were broadcast within the system every first period of time or less for at least a second period of time, the first period of time less than the second period of time. In response to determining that the change messages were broadcast within the system every first period of time or less for at least the second period of time, the hardware devices signals that an error has been detected. | 08-27-2015 |
