摘要： I/O requests from hosts in a data storage system are blocked or rate-restricted upon detection of an unbalanced or overload condition in order to prevent timeouts by host computers, and achieve an aggregate reduction of data access latency. The blockages are generally of short duration, and are transparent to hosts, so that host timeouts are unlikely to occur. During the transitory suspensions of new I/O requests, server queues shorten, after which I/O requests are again enabled.
摘要翻译：在检测到不平衡或过载状况时，数据存储系统中主机的I / O请求被阻止或限速，以防止主计算机超时，并实现数据访问延迟的总体减少。阻塞通常时间短，对主机是透明的，因此主机超时不可能发生。在新的I / O请求暂停期间，服务器队列缩短，之后再次启用I / O请求。

摘要： A method for data distribution, including distributing logical addresses among an initial set of devices 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, 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 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, forming a depleted set, the logical addresses oldie 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之间分配逻辑地址以提供平衡访问，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置中的设备传送到附加设备。在初始设置中基本上不传送逻辑地址。如果从初始集合中删除剩余设备，形成耗尽集合，则在耗尽集合之间重新分配冗余设备的逻辑地址。在耗尽组中基本上不传送逻辑地址。在这两种情况下，维持平衡的访问。

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