摘要： A method and system for performing tasks when processing a client service request. The service request is processed by a group of processing elements including a main processing element and at least one offloading processing element. A subset of tasks is assigned to at least one of the offloading processing elements. When a service request is received from the client at the group of processing elements, each offloading processing element determines whether processing of the service request requires performing a task contained in the subset of tasks assigned to the respective offloading processing element. If processing of the service request requires performing tasks comprised in the subset of tasks assigned to the respective offloading processing element, those tasks are performed and outputs of the tasks are transmitted back directly from the offloading processing element to the client.

摘要： The present idea provides a high read and write performance from/to a solid state memory device. The main memory of the controller is not blocked by a complete address mapping table covering the entire memory device. Instead such table is stored in the memory device itself, and only selected portions of address mapping information are buffered in the main memory in a read cache and a write cache. A separation of the read cache from the write cache enables an address mapping entry being evictable from the read cache without the need to update the related flash memory page storing such entry in the flash memory device. By this design, the read cache may advantageously be stored on a DRAM even without power down protection, while the write cache may preferably be implemented in nonvolatile or other fail-safe memory. This leads to a reduction of the overall provisioning of nonvolatile or fail-safe memory and to an improved scalability and performance.

摘要翻译： 本想法提供了从/到固态存储器件的高读/写性能。 控制器的主存储器不被覆盖整个存储器件的完整地址映射表阻止。 相反，这样的表被存储在存储器设备本身中，并且只有地址映射信息的选定部分被缓存在读取高速缓存和写入高速缓存中的主存储器中。 读取高速缓存与写入高速缓存的分离使得能够从读取的高速缓存中取出地址映射条目，而不需要在闪存设备中更新存储这样的条目的相关闪存页面。 通过这种设计，读取高速缓存可以有利地存储在DRAM上，即使没有掉电保护，而写入高速缓存也可以优选地被实现在非易失性或其它故障安全存储器中。 这导致了非易失性或故障安全存储器的总体配置的减少以及改进的可扩展性和性能。

摘要： A method for optimizing locations of physical data accessed by one or more client applications interacting with a storage system, with the storage system comprising at least two redundancy groups having physical memory spaces and data bands. Each of the data bands corresponds to physical data stored on several of the physical memory spaces. A virtualized logical address space includes client data addresses utilizable by the one or more client applications. A storage controller is configured to map the client data addresses onto the data bands, such that a mapping is obtained, wherein the one or more client applications can access physical data corresponding to the data bands.

摘要： A method for intra-block wear leveling within solid-state memory subjected to wear, having a plurality of memory cells includes the step of writing to at least certain ones of the plurality of memory cells, in a non-uniform manner, such as to balance the wear of the at least certain ones of the plurality of memory cells within the solid-state memory, at intra-block level. For example, if a behavior of at least some of the plurality of memory cells is not characterized, then the method may comprise characterizing a behavior of at least some of the plurality of memory cells and writing to at least certain ones of the plurality of memory cells, based on the characterized behavior, and in a non-uniform manner.
