摘要： Techniques for detection of impending data errors in a mass storage system, such as a track squeeze problem in an electromagnetic disk drive, and then repairing the impending problem, such as by rewriting the affected tracks. In many cases the problem is detected and repair is effected when the original data can still be read. In other cases, when the data is no longer readable on the disk in question, but when the disk is part of a Redundant Array of Independent Disks (RAID) system, or other system in which higher layer fault tolerance mechanisms are implemented, the missing data can be recovered via these mechanisms. The recovered data is then used to repair the track squeeze problem. The invention can be implemented as firmware in a storage system, as a component of a general purpose operating system, or inside individual disk drives, or it can use a combination of these implementations.

摘要： A method for processing data packets in a network communication environment as shown in Figure 5. In response to receiving an acknowledgment of a previously sent burst of data packets, the amount of data acknowledged is compared to the amount of data in the burst that was originally sent. If the acknowledgments covers at least a predetermined amount of or more in the original burst, then a burst size parameter is increased for future communication; however, if the acknowledgment covers less than the predetermined amount of the original burst, then the burst size parameter remains the same.

摘要翻译：用于检测大容量存储系统中即将发生的数据错误的技术，例如电磁盘驱动器中的轨道挤压问题，然后修复即将发生的问题，例如通过重写受影响的轨道。在许多情况下，当原始数据仍然被读取时，检测到问题并进行修复。在其他情况下，当数据在有问题的磁盘上不再可读时，但是当磁盘是独立磁盘冗余阵列（RAID）系统或实施更高层容错机制的其他系统的一部分时，缺少可以通过这些机制回收数据。然后，恢复的数据用于修复轨道挤压问题。本发明可以实现为存储系统中的固件，作为通用操作系统的组件，或者在单独的磁盘驱动器内，或者可以使用这些实现的组合。

摘要： Systems for managing data storage are described. The systems manage responses to requests from a plurality of clients for access to a set of resources, and more efficiently responds to client load changes in storage area network (SAN) by migrating data blocks while providing continuous data access. The systems include a plurality of optionally equivalent servers wherein the set of resources is partitioned across these servers. Each (equivalent) server has a load monitor process that can communicate with the other load monitor processes for generating a measure of the client load on the server system and the client load on each of the respective servers. The system further comprises a resource distribution process that redistribute the client load by repartitioning the set of resources in response to the measured system load. In addition, each server may include a routing table that includes a reference for each resource that is maintained on the partitioned resource server. Requests from a client are processed as a function of the routing table to route the request to the individual server that maintains or has control over the resource of interest. For archiving purposes, a snapshot process may operate on a server, optionally in cooperation with other snapshot processes for generating state information representative of the state of the partitioned storage volume.
