摘要： A system (10) for transferring data to and from one or more slow-access-time-mass-storage nodes (12) which store data at respective first ranges of logical block addresses (LBAs), including a plurality of interim-fast-access-time nodes (20) which are configured to operate independently of one another. Each interim-fast-access-time node (20) is assigned a respective second range of the LBAs and is coupled to receive data from and provide data to the one or more slow-access-time-mass-storage nodes (12) within the respective second range.
The system (10) further includes one or more interface nodes (26), which are adapted to receive input/output (10) requests from host processors (52) directed to specified LBAs and to direct all the IO requests to the interim-fast-access-time node to which the specified LBAs are assigned.

摘要： A method for data distribution, including distributing logical addresses among an initial set of devices (14, 16, 18, 20, 22) so as provide balanced access, and transferring the data to the devices in accordance with the logical addresses.
If a device is added to the initial set (14, 16, 18, 20, 22), forming an extended set, the logical addresses are redistributed among the extended set so as to cause some logical addresses to be transferred from the devices in the initial set (14, 16, 18, 20, 22) to the additional device. There is substantially no transfer of the logical addresses among the initial set.
If a surplus device is removed from the initial set(14, 16, 18, 20, 22), forming a depleted set, the logical addresses of the surplus device are redistributed among the depleted set. There is substantially no transfer of the logical addresses among the depleted set.
In both cases the balanced access is maintained.
摘要翻译：一种用于数据分配的方法，包括在初始设备集合（14,16,18,20,22）之间分配逻辑地址，以便提供平衡的访问，并且根据逻辑地址将数据传送到设备。如果将设备添加到初始设置（14,16,18,20,22）中，形成扩展集合，则在扩展集合之间重新分配逻辑地址，以便使一些逻辑地址从初始设定（14，16，18，20，22）到附加设备。在初始集合中基本上不传送逻辑地址。如果剩余设备从初始设置（14,16,18,20,22）中移除，形成耗尽组，则冗余设备的逻辑地址在耗尽组中重新分配。在耗尽组之间基本上没有逻辑地址的传送。在这两种情况下，平衡访问得到维护。

摘要： A storage system (20), consisting of one or more data storage logical units (LUs) (61) formed in physical media (64, 66, 68, 70). The LUs (61) are adapted to receive commands and responsively to the commands to store and recall data. The storage system (20) further includes a plurality of ports (22, 24, 26), each port (22, 24, 26) being adapted to maintain a respective LU command queue for each of the LUs (61), such that upon receiving a command directed to one of the LUs (61), the port (22, 24, 26) places the received command in the respective LU command queue. The port (22, 24, 26) converts the received command to one or more converted commands at least some of which are directed to the physical media (64, 66, 68, 70) of the one of the LUs (61). The port (22, 24, 26) then conveys the commands directed to the physical media (64, 66, 68, 70) in an order determined by the respective LU command queue.
