    • Techniques for enabling remote storage utilization as local disk resources. A virtual disk drive comprising an emulation of a non-existent local (to a client) disk drive is facilitated via out-of-band (OOB) communications with a remote storage server in a manner that is transparent to an operating system (OS) running on the client. Storage access requests are processed in a conventional manner by the client OS, being passed as a block storage request to a firmware driver. The firmware driver redirects the request to a remote agent running on the remote storage server via a LAN microcontroller on the client using an OOB channel. A listener at the remote server routes packets to the remote agent. The remote agent performs a logical-to-physical storage block translation to map the storage request to appropriate storage blocks on the server. In one embodiment, an image of the virtual disk is stored in a single file on the server. The scheme supports diskless clients, disk mirroring and remote OS provisioning.
    • 使远程存储利用成为本地磁盘资源的技术。 以对操作系统(OS)是透明的方式,通过与远程存储服务器的带外(OOB)通信来促进包括不存在的本地(到客户端)磁盘驱动器的仿真的虚拟磁盘驱动器, 在客户端上运行 存储访问请求由客户端OS以常规方式处理,作为块存储请求被传递给固件驱动程序。 固件驱动程序通过使用OOB通道的客户端上的LAN微控制器将请求重定向到在远程存储服务器上运行的远程代理。 远程服务器上的侦听器将数据包路由到远程代理。 远程代理执行逻辑到物理存储块转换,以将存储请求映射到服务器上的相应存储块。 在一个实施例中,虚拟盘的图像被存储在服务器上的单个文件中。 该方案支持无盘客户端,磁盘镜像和远程操作系统配置。

    • A method, system, and article of manufacture to efficiently support interrupts of a computer system. A message-based interrupt from a device of the computer system is intercepted. A fake line-based interrupt for the device corresponding to the message-based interrupt is determined, wherein an operating system (OS) of the computer system is not message-based interrupt capable. The fake line-based interrupt is issued to the OS. A query from the OS regarding the fake line-based interrupt is serviced, the query to determine if the fake line-based interrupt was from the device. An interrupt vector associated with the message-based interrupt is provided to the OS.
    • 一种有效支持计算机系统中断的方法,系统和制品。 来自计算机系统的设备的基于消息的中断被截取。 确定与基于消息的中断相对应的设备的基于假线路的中断,其中计算机系统的操作系统(OS)不是基于消息的中断能力。 假的基于行的中断被发布到操作系统。 来自操作系统的关于基于假线路的中断的查询被服务,查询以确定假的基于行的中断是否来自设备。 与基于消息的中断相关联的中断向量被提供给OS。
