摘要： Computer networks are provided with a resource efficient ability to generate link performance statistics. To calculate the average link utilization per I/O operation, a first counter accumulates the number of I/O operations processed by a link and a second counter accumulates the time required by the link to complete each I/O operation. The second value is then divided by the first value. The number of operations per second for a link may be computed by dividing the first number by a predetermined period of time and the average number of operations using the link may be computed by dividing the second number by the predetermined period of time. A third counter may be employed to accumulate the number of bytes transferred by a link during each I/O operation. Then, average size of an I/O operation may be computed by dividing the third number by the first number and the average bandwidth per link operation may be computed by dividing the third number by the predetermined period of time. Separate sets of counters are preferably associated with each of several link types associated with a single port, thereby allowing separate statistics to be generated for each link type. The generated statistics are useful for such activities as problem resolution, load balancing and capacity planning.

摘要： An apparatus, system, and method are disclosed for fastload code update on a communications adapter. The apparatus includes an image load module, a memory initialization module, and an image overlay module. The image load module is configured to load a copy of a new code image in a memory on the communications adapter. The memory also concurrently stores a copy of an old code image used by the communications adapter. The memory initialization module is configured to invoke the new code image to perform a memory initialization operation. The memory initialization module may perform the memory initialization operation concurrently with ongoing I/O requests possibly accepted, but not necessarily processed, by the old code image. The image overlay module is configured to overlay the old code image with the new code image. The fastload code update minimizes the time that the communications adapter is off-line to overlay the old code image with the new code image and reinitialize the communications adapter.

摘要： Methods, system and computer program product are provided to improve the efficiency of data transfers in a PPRC environment. Any or all of three features may be implemented, each of which reduces the number of round trips required for the exchange of handshaking, data and control information. A first feature includes disabling the “transfer ready” acknowledgment which normally occurs between a primary storage controller and a secondary storage controller. A second feature includes pre-allocating payload and data buffers in the secondary storage controller. A third feature includes packaging write control information with a write command in an extended command descriptor block (CDB). Such a step eliminated the need for a separate transmission of the write control information. The CDB is transmitted along with a data block from the primary storage controller to the secondary storage controller and placed in the respective, pre-allocated buffers. Data may also be pipelined to the secondary. By decreasing the response time for data transfers, the distance separating the primary and secondary storage controllers may be increased.
摘要翻译：提供了方法，系统和计算机程序产品，以提高PPRC环境中数据传输的效率。可以实现三个特征中的任何一个或全部，每个特征减少交换握手，数据和控制信息所需的往返次数。第一个功能包括禁用通常在主存储控制器和辅助存储控制器之间发生的“传送就绪”确认。第二特征包括在副存储控制器中预分配有效载荷和数据缓冲器。第三个特征包括在扩展命令描述符块（CDB）中用写入命令封装写入控制信息。这样的步骤消除了对写入控制信息的单独发送的需要。 CDB与来自主存储控制器的数据块一起传送到辅助存储控制器并且被放置在相应的预先分配的缓冲器中。数据也可以流水线到次级。通过减少数据传输的响应时间，可以增加分离主存储控制器和辅助存储控制器的距离。

摘要： An apparatus, system, and method are disclosed for concurrently relocating a RAID array. The apparatus includes an identification module, a designation module, and an implementation module. The identification module identifies an availability of a physical device within a donor arrayed storage device to offload a source drive of a relocation enclosure. The designation module designates an available physical device as a target drive and thereby designate the target drive and the source drive as a linked pair;. The implementation module implements a mirroring relationship between the target drive and the source drive. The apparatus, system, and method provide a dynamic relocation of the raid array, minimizing system downtime and maximizing efficient utilization of system resources.
