摘要： Placing virtualization agents in the switches which comprise the SAN fabric. Higher level virtualization management functions are provided in an external management server. Conventional HBAs can be utilized in the hosts and storage units. In a first embodiment, a series of HBAs are provided in the switch unit. The HBAs connect to bridge chips and memory controllers to place the frame information in dedicated memory. Routine translation of known destinations is done by the HBA, based on a virtualization table provided by a virtualization CPU. If a frame is not in the table, it is provided to the dedicated RAM. Analysis and manipulation of the frame headers is then done by the CPU, with a new entry being made in the HBA table and the modified frames then redirected by the HBA into the fabric. This can be done in either a standalone switch environment or in combination with other switching components located in a director level switch. In an alternative embodiment, specialized hardware scans incoming frames and detects the virtualized frames which need to be redirected. The redirection is then handled by translation of the frame header information by hardware table-based logic and the translated frames are then returned to the fabric. Handling of frames not in the table and setup of hardware tables is done by an onboard CPU.

摘要： Systems particularly a virtualization switch or a storage device, which include virtual ports connected to virtual devices with virtual worldwide names and virtual LUNs. Because Fibre Channel environment hosts can track worldwide names from one port to another and allow continuity in that regard, the virtual worldwide names are provided with relevant virtual LUNs and connected these to virtual ports so that the virtual devices can be moved as desired to overcome failures or to allow load balancing.

摘要： An application programming interface (API), functioning as an interface between a storage controller and an owning application, is used to migrate, from a specified source LUN to a specified target LUN, at least one specified sub-LUN data chunk, the at least one specified sub-LUN data chunk having a predefined chunk size fixed by the storage controller. A specified total migration size is incrementally reduced by each completed migration of the at least one specified sub-LUN data chunk until the total migration size is zero and the migration is completed.

摘要： Mechanisms identify one or more first storage devices in a first tier of the tiered storage system that may be placed in a minimal power consumption state and identify one or more data segments stored on the one or more first storage devices that are most likely to be accessed during a period of time in which the one or more first storage devices are in the minimal power consumption state. The mechanisms migrate the one or more data segments to one or more second storage devices in one of the first tier or a second tier of the storage system and place the one or more first storage devices in the minimal power consumption state. Access requests to the one or more data segments are serviced by the one or more second storage devices while the one or more first storage devices are in the minimal power consumption state.

摘要： Control of the discard of data from cache during backup of the data. In a computer-implemented system comprising primary data storage; cache; backup data storage; and at least one processor, the processor is configured to identify data stored in the primary data storage for backup to the backup data storage, where the identified data is placed in the cache in the form of portions of the data, and where the portions of data are to be backed up from the cache to the backup storage. Upon backup of each portion of the identified data from the cache to the backup storage, the processor marks the backed up portion of the identified data for discard from the cache. Thus, the backed up data is discarded from the cache right away, lessening cache pollution.

摘要： An approach to efficient space reclamation in multi-layered thinly provisioned systems. A parent storage volume is thinly provisioned, and uses one or more child storage volumes that are also thinly provisioned for storage. A reclamation command sent to the device providing the parent thinly provisioned storage volume identifies that data has been released, and that the physical storage storing that data can be placed in a free pool and used to satisfy future write requests in the parent storage volume. An identify module identifies which child storage volumes supporting the parent storage volume are thinly provisioned. The data is released at the level of the parent storage volume, and the reclamation command is sent to the child storage volumes supporting the parent storage volume and that are themselves thinly provisioned. The storage is thus released by all affected thinly provisioned storage volumes, and not just the parent storage volume that received the reclamation command.
摘要翻译：一种在多层薄配置系统中高效空间回收的方法。父存储卷被稀疏地配置，并且使用一个或多个也被稀疏地配置用于存储的子存储卷。发送到提供父瘦的配置存储卷的设备的回收命令标识该数据已经被释放，并且存储该数据的物理存储可以被放置在空闲池中并用于满足父存储卷中的未来写入请求。识别模块识别支持父存储卷的哪个子存储卷被稀疏地配置。数据在父存储卷的级别被释放，并且回收命令被发送到支持父存储卷的子存储卷，并且本身被稀释地配置。因此，所有受影响的瘦配置存储卷都会释放存储空间，而不仅仅是接收到回收命令的父存储卷。

摘要： A method for increasing the efficiency of a “copy-on-write” operation performed on an SSD to extend the life of the SSD is disclosed herein. In one embodiment, such a method includes receiving a first logical address specifying a logical location where new data should be written to an SSD. The first logical address maps to a first physical location, storing original data, on the SSD. The method further receives a second logical address specifying a logical location where the original data should be available on the SSD. The second logical address maps to a second physical location on the SSD. To efficiently perform the copy-on-write operation, the method writes the new data to a new physical location on the SSD, maps the first logical address to the new physical location, and maps the second logical address to the first physical location. A corresponding apparatus is also disclosed.
