    Abstract: A storage switch in accordance with an embodiment of the invention is a highly scalable switch that allows the creation of a SAN that is easy to deploy and that can be centrally managed. Moreover, such a storage switch also allows the deployment of a global infrastructure, allowing the resources of the SAN, such as storage devices, to essentially be positioned anywhere on the globe. Further, such a storage switch allows a multi-protocol SAN, e.g., one that includes both iSCSI or Fibre Channel, and processes data packets at “wire speed.” To further enable wire-speed processing, a switch in accordance with the invention has “intelligence” distributed to each of its linecards, through which it classifies packets into data and control packets, it performs virtualization functions, and it performs protocol translation functions. A switch in accordance with the invention further performs serverless storage services such as mirroring, snapshot, and replication.

    Abstract: A system in accordance with an embodiment of the invention provides Quality of Service (QoS) for Storage Access. Such QoS is partially enabled in one embodiment by the automatic pooling of storage devices and provisioning virtual targets from those pools. QoS is enforced in one embodiment by keeping the bandwidth for each connection within a specified range, and particularly, by controlling the number of allowed concurrent requests from an initiator. Load balancing is also provided in one embodiment, improving response times for requests, further easing the ability to provide QoS.

    Abstract: A host adapter contains a RISC processor, a local memory, and a memory management unit that permits the RISC processor and a host computer system to access a local memory. The host computer system writes command descriptions directly into the local RAM. The RISC processor retrieves and processes the command descriptions. The local RAM may be divided into numbered command description blocks having a fixed size and format. In standard bus protocols, such as SCSI-2, block numbers are used as tag messages. Such tag messages allow the host adapter to quickly identify information used when an SCSI I/O request is resumed. The command description blocks may be linked into lists, including an active list containing command description blocks that are ready for the RISC processor and a free list containing command description blocks that are available for use by the host computer.

    Abstract translation: 主机适配器包含RISC处理器，本地存储器以及允许RISC处理器和主机系统访问本地存储器的存储器管理单元。 主机系统将命令描述直接写入本地RAM。 RISC处理器检索和处理命令描述。 本地RAM可以被划分为具有固定大小和格式的编号命令描述块。 在标准总线协议（如SCSI-2）中，块号用作标签消息。 这样的标签消息允许主机适配器快速识别恢复SCSI I / O请求时所使用的信息。 命令描述块可以链接到列表中，包括包含用于RISC处理器的命令描述块的活动列表和包含可供主计算机使用的命令描述块的空闲列表。
