摘要： A system including flash memory modules and a system controller. Each flash memory module includes flash memory chips and a memory controller to manage a plurality of blocks in the plurality of flash memory chips. The blocks are units for erasing data stored in the flash memory chips. The system controller performs wear leveling by exchanging data between a first flash memory module and a second flash memory module of the flash memory modules.

摘要： An administrator provisions a virtual disk in a remote storage platform and defines policies for that virtual disk. A virtual machine writes to and reads from the storage platform using any storage protocol. Virtual disk data within a failed storage pool is migrated to different storage pools while still respecting the policies of each virtual disk. Snapshot and revert commands are given for a virtual disk at a particular point in time and overhead is minimal. A virtual disk is cloned utilizing snapshot information and no data need be copied. Any number of Zookeeper clusters are executing in a coordinated fashion within the storage platform, thus increasing overall throughput. A timestamp is generated that guarantees a monotonically increasing counter, even upon a crash of a virtual machine. Any virtual disk has a “hybrid cloud aware” policy in which one replica of the virtual disk is stored in a public cloud.
摘要翻译：管理员在远程存储平台中提供虚拟磁盘，并为该虚拟磁盘定义策略。虚拟机使用任何存储协议对存储平台进行写入和读取。故障存储池中的虚拟磁盘数据将迁移到不同的存储池，同时仍然遵循每个虚拟磁盘的策略。在特定时间点为虚拟磁盘提供快照和恢复命令，开销最小。使用快照信息克隆虚拟磁盘，无需复制数据。任何数量的Zookeeper集群都以协调的方式在存储平台内执行，从而提高总体吞吐量。生成时间戳，即使在虚拟机崩溃时也能保证单调递增的计数器。任何虚拟磁盘都具有“混合云感知”策略，其中虚拟磁盘的一个副本存储在公共云中。

摘要： A storage layer is configured to store data at respective offsets within storage units of a storage device. Physical addresses of the data may be segmented into a first portion identifying the storage unit in which the data is stored, and a second portion that indicates the offset of the data within the identified storage unit. An index of the data offsets (e.g., second portions of the physical addresses) may be persisted on the storage device. The first portion of the address may be associated with logical addresses of the data in a forward index. The forward index may omit the second portion of the physical addresses, which may reduce the memory overhead of the index and/or allow the forward index to reference larger storage devices. Data of a particular logical address may be accessed using the first portion of the physical address maintained in the forward index, and the second portion of the media address stored on the storage device.
摘要翻译：存储层被配置为在存储设备的存储单元内的相应偏移处存储数据。数据的物理地址可以被分割成识别其中存储数据的存储单元的第一部分，以及指示所识别的存储单元内的数据的偏移的第二部分。数据偏移的索引（例如，物理地址的第二部分）可以被持久存储在存储设备上。地址的第一部分可以与前向索引中的数据的逻辑地址相关联。前向索引可以省略物理地址的第二部分，这可以减少索引的存储器开销和/或允许前向索引引用较大的存储设备。可以使用保存在前向索引中的物理地址的第一部分和存储在存储设备上的媒体地址的第二部分来访问特定逻辑地址的数据。

摘要： An apparatus, system, and method are disclosed for storage space recovery. A storage division selection module selects a first storage division for recovery. The first storage division comprises a portion of solid-state storage in a solid-state storage device. A data recovery module reads valid data from the first storage division in response to selecting the first storage division for recovery. The data recovery module stores the valid data in a second storage division of the solid-state storage device. The data recovery module passes the valid data through at least a portion of a write data pipeline for the solid-state storage device without passing the valid data to a host device and/or without routing the valid data outside of a solid-state storage controller for the solid-state storage device.

摘要： A system of Flash EEprom memory chips with controlling circuits serves as non-volatile memory such as that provided by magnetic disk drives. Improvements include selective multiple sector erase, in which any combinations of Flash sectors may be erased together. Selective sectors among the selected combination may also be de-selected during the erase operation. Another improvement is the ability to remap and replace defective cells with substitute cells. The remapping is performed automatically as soon as a defective cell is detected. When the number of defects in a Flash sector becomes large, the whole sector is remapped. Yet another improvement is the use of a write cache to reduce the number of writes to the Flash EEprom memory, thereby minimizing the stress to the device from undergoing too many write/erase cycling.
