摘要： Disclosed is a system for installing operating system files on logical unit numbers (LUNs). At a SAS switch, a command to initiate an operating system installation on a LUN)associated with a SAS host bus adapter (HBA) connected to said SAS switch is received. In response to the command, a PXE session with a PXE server is established. Using the PXE session, operating system files are transferred to the LUN via the SAS switch thereby installing the operating system on said LUN.

摘要： Disclosed is a storage enclosure having a plurality of servers each having a storage controller. A second storage controller that is not part of any of the plurality of servers is embedded in the storage enclosure. The second storage controller is configured to process I/O commands directed to one of the server's storage controllers when a storage controller fails. In this manner, the storage controllers that are part of the servers may be fully utilized and still have a failover capability to the enclosure storage controller instead of another server storage controller that may also be fully utilized.

摘要： Disclosed are storage controllers that can share resources (e.g., memory, CPU cycles, I/O bandwidth, etc.). The storage controllers are coupled via a resource sharing cable. When one storage controller determines a resource constraint exists that would prevent completion of a command by the storage controller, the storage controller queries or determines an availability of the resource on a second storage controller. If the resource is available, and can be shared, the storage controller uses the resource on the second storage controller to complete the command.

摘要： Disclosed is a method and mechanism for virtualizing the resources of multiple physical storage controller cards/HBAs available to a host computer system into a single virtual controller. An Advanced Storage Driver (ASD) may be inserted in a layer above the base device drivers of the storage controllers/HBAs and act as a single virtual controller for access to the end target devices connected to the multiple physical storage controllers/HBAs so that at any point in time the resources of each of the controllers/HBAs may be dynamically allocated to the various requested operations. The ASD may have bi-directional communication with each controller/HBA firmware directly and/or with the base device driver associated with each controller/HBA in order to permit both direct and base device driver controlled communication with each of the physical controllers/HBAs. The ASD may further provide load sharing between the controllers/HBAs as well as fault tolerance functionality to reroute communications through a different controller/HBA in the event of a failure of one or more of the controllers/HBAs.
摘要翻译：公开了一种用于将主计算机系统可用的多个物理存储控制器卡/ HBA的资源虚拟化为单个虚拟控制器的方法和机制。可以将高级存储驱动器（ASD）插入到存储控制器/ HBA的基本设备驱动器上方的层中，并且用作访问连接到多个物理存储控制器/ HBA的终端目标设备的单个虚拟控制器，使得任何时间点，每个控制器/ HBA的资源可以动态地分配给各种请求的操作。 ASD可以与每个控制器/ HBA固件直接和/或与每个控制器/ HBA相关联的基本设备驱动器进行双向通信，以便允许直接和基本设备驱动器与每个物理控制器/ HBA的受控通信。 ASD可以进一步提供控制器/ HBA之间的负载共享以及在一个或多个控制器/ HBA发生故障的情况下通过不同控制器/ HBA重新路由通信的容错功能。
