摘要： A system for enabling SATA drives to be utilized in FC SANs is disclosed. To send data to a SATA drive over a FC SAN, a host sends SCSI commands encapsulated in FC frames over a standard FC link to a Fibre Channel Attached SATA Tunneling (FAST) RAID controller, where the SCSI commands are de-encapsulated from the FC frames and translated to SATA FISs. The SATA FISs are thereafter encapsulated into FC frames. The IOC that performs these functions is referred to as a FAST IOC. The SATA-encapsulated FC frames are sent to multiple disk drive enclosures over another standard FC link. The FC frames are de-encapsulated by FAST switches in disk drive enclosures to retrieve the SATA FISs, and the SATA FISs are sent to the SATA drives over a SATA connection.

摘要： A method is disclosed for maintaining a table of recent accesses for each port for use in predicting whether a request for data from a source device is likely to be sent to a high speed or low speed destination device. The table of recent accesses lists every source device attached to that port and the speed of the destination device with the most recent access to each source device. When an OPN primitive is received at the source port, the source device is identified and used with the table of recent accesses to predict whether the destination device is likely to be high speed or low speed, and ultimately whether to send data from the source device or reject the request.

摘要： Snooping in SAS expander networks is disclosed. Ports in a SAS expander may include snoop circuitry and a snoop tap which allows snoop data to be diverted for snooping prior to any significant transformation of the traffic by the regular port logic. Furthermore, the snoop circuitry can receive OOB signaling and convert it to K characters for transmission through the SAS network and subsequent analysis by a protocol analyzer. The ports and cascades in the expander network can be configured to create snoop paths to enable snoop data to be passed through the network to locations where a protocol analyzer can be easily attached. With SAS snoop ports, there is no disruption to the system. Because only a copy of the data is routed to the analyzer, there is no change to the original signal path and latency is identical with or without the analyzer.
摘要翻译：披露了SAS扩展器网络中的侦听。在SAS扩展器中的端口可以包括窥探电路和窥探抽头，其允许窥探数据被转移以在通过常规端口逻辑的业务的任何重大变换之前进行窥探。此外，监听电路可以接收OOB信令，并将其转换为K字符，以便通过SAS网络进行传输，然后由协议分析器进行后续分析。扩展器网络中的端口和级联可以配置为创建窥探路径，以使窥探数据能够通过网络传递到协议分析器可以轻松连接的位置。使用SAS snoop端口，系统不会中断。因为只有数据的副本才能路由到分析仪，所以原始信号路径没有改变，延迟与分析仪是否相同。

摘要： Described herein is an improved mechanism for bridging between SAS and SATA drives based upon existing SAS expanders in a SAS domain. In particular, a bridge capable of translating between SAS and SATA protocols is embedded in or coupled to an expander. When a SAS initiator request is received at the expander, the expander can route the request, based on a routing table, either directly to a destination SAS device or to the bridge for necessary translation before it is transmitted to a destination SATA drive. The routing table includes corresponding relationships between all SAS addresses and Phys through which those SAS and SATA devices are attached to the expander. SATA devices can be virtualized in the expander through a few assigned addresses in the routing table in a SAS discovery process.

摘要： The attaching of labels to an OPEN frame and applying label switched routing to SAS expanders is disclosed to eliminate the need for large routing tables in SAS networks. A label stack is inserted into the OPEN frame by the initiator, prior to the OPEN frame being transmitted. Each label contains the egress port for a SAS expander in the transmit path. Each SAS expander to be participating in the connection reads the labels to determine the egress port to connect to and through which data is to be sent. The SAS expander marks its label invalid or discards it and forwards the OPEN frame to the egress port where the next SAS expander will look for the first valid label. The process repeats until the OPEN frame reaches the edge device, at which time all labels are discarded and the OPEN frame is forwarded to the end device.
摘要翻译：公开了将标签附加到OPEN帧并且将标签交换路由应用于SAS扩展器以消除对SAS网络中的大路由表的需要。在发送OPEN帧之前，发起者将标签堆栈插入OPEN帧。每个标签包含发送路径中SAS扩展器的出口端口。要参与连接的每个SAS扩展器都会读取标签，以确定要连接的出口端口以及要发送的数据。 SAS扩展器标记其标签无效或丢弃它，并将OPEN帧转发到出口端口，下一个SAS扩展器将寻找第一个有效标签。该过程重复，直到OPEN帧到达边缘设备，此时所有标签都被丢弃，OPEN帧被转发到终端设备。

摘要： The discovery and configuration of devices of interest connected to the Ethernet by an Ethernet port is disclosed. To perform discovery, Client software in a management interface transmits packets including the address of the management interface and a port identifier to a known broadcast address, requesting the MAC address for all devices of interest. Server software in the devices of interest parse the broadcast packets and broadcast a packet containing a MAC address that uniquely identifies the devices of interest back to the Client. Once the MAC addresses are returned to the Client, the Client can then broadcast protocol packets requesting the configuration of a specific device of interest such as a new IP address. Once a device of interest is configured with at least an IP address, the device of interest can communicate using TCP/IP, and it can thereafter be managed using higher level tools and firmware.

摘要： Embodiments of the invention enable error simulation for system validation. Errors can be simulated by modifying data presented to the processor as well as generating interrupts consistent with the modified data in the ASIC hardware. Modify logic may be added to the ASIC so when the microprocessor attempts to read a specific address, the modify logic may mask one or more of the data bits returned by the requested address. Address, bit mask, and force value data may be stored in registers to determine which address may be modified, the bit location to be modified, and the value that bit location should be changed to. Selection logic may then determine whether data from the modify logic or the unmodified value from an attached device should be sent to the ASIC interface and on to the microprocessor. A timer may also be used to decouple the setup from the test.

摘要： Controlling accesses to target devices such as disk drives by modifying the duty cycle profile of those devices to improve device reliability is disclosed. The utilization of a target device is monitored, and if a device is being overused, that device is given a rest period by reserving it for a special initiator that does not send any commands to the device for a certain period of time. This reduced utilization has the effect of increasing the reliability of the target device. This period of time also adds a delay to the processing of commands for the target device being overutilized so that the device becomes less responsive. This performance penalty creates pressure on system administrators to reduce the number of commands sent to that target device and/or move data to proper devices (that can handle the high number of accesses).
摘要翻译：公开了通过修改这些设备的占空比轮廓以提高设备可靠性来控制对目标设备（例如磁盘驱动器）的访问。对目标设备的使用情况进行监控，如果设备被过度使用，该设备将通过为特定启动器预留一段休息时间，该启动器不会向设备发送任何命令一段时间。这种降低的利用率具有提高目标设备的可靠性的效果。这个时间段也增加了对目标设备被过度利用的命令的处理的延迟，使得该设备的响应性降低。这种性能损失会给系统管理员造成压力，以减少发送到该目标设备的命令数量和/或将数据移动到适当的设备（可以处理大量访问）。
