Abstract: A system for performing on-line reconfiguration of a disk array in which a source logical volume is reconfigured to a destination logical volume. Disk array configuration is invoked if a new physical drive is inserted, or a drive is removed. Reconfiguration can also be performed if the user desires to change the configuration of a particular logical volume, such as its stripe size. The disk array reconfiguration is run as a background task by firmware on a disk controller board. The reconfigure task first moves data from the source logical volume to a posting memory such as RAM memory. The reconfigure task operates one stripe at a time, with the stripe size being that of the destination logical volume. Once a stripe of data is moved into the posting memory, it is written back to corresponding locations in the destination logical volume. The reconfigure task continues until all data in the source logical volume have been moved into the destination logical volume. While the reconfigure task is working on a particular logical volume, data remains accessible to host write and read requests.

Abstract translation: 用于执行其中将源逻辑卷重新配置为目标逻辑卷的磁盘阵列的在线重新配置的系统。 如果插入新的物理驱动器或驱动器被删除，则调用磁盘阵列配置。 如果用户希望更改特定逻辑卷的配置，例如其条带大小，也可以执行重新配置。 磁盘阵列重新配置以磁盘控制器板上的固件作为后台任务运行。 重新配置任务首先将数据从源逻辑卷移动到诸如RAM存储器之类的发布存储器。 重新配置任务一次操作一个条带，条带大小是目标逻辑卷的条带大小。 一旦将数据条带移动到发布内存中，就将其写回目标逻辑卷中的相应位置。 重新配置任务继续，直到源逻辑卷中的所有数据都已移动到目标逻辑卷中。 重新配置任务正在处理特定的逻辑卷时，主机写入和读取请求的数据仍然可以访问。

Abstract: A computer having a storage subsystem and an array controller circuit controlling an array of hard drives in the storage subsystem. Upon powering the storage subsystem, the array controller automatically determines whether the hard drives have been moved to new bay locations in the storage subsystem and whether a new complete logical drive, consisting of at least one hard drive, has been added to the storage subsystem. Upon discovery of any drive movement or logical drive unit addition, the array controller automatically reconfigures each hard drive by at least updating the configuration information in accordance with the changes.

Abstract: A system and/or network (50) for connecting at least one server (52) to at least one storage device (56) via a Fibre Channel (54). Such a system is capable of providing connection redundancy, high speed data rates, multiple operating systems and, hot plugging. Furthermore, the system allows for a large number of devices to be connected to the Fibre Channel. The devices, being servers, storage devices, or other system related appliances can be separated by more than 10 miles and still communicate via the Fibre Channel at high data rates.
