摘要： A method for adjustable error correction in a storage cluster is provided. The method includes determining health of a non-volatile memory of a non-volatile solid-state storage unit of each of a plurality of storage nodes in a storage cluster on a basis of per flash package, per flash die, per flash plane, per flash block, or per flash page. The determining is performed by the storage cluster. The plurality of storage nodes is housed within a chassis that couples the storage nodes as the storage cluster. The method includes adjusting erasure coding across the plurality of storage nodes based on the health of the non-volatile memory and distributing user data throughout the plurality of storage nodes through the erasure coding. The user data is accessible via the erasure coding from a remainder of the plurality of storage nodes if any are unreachable.

摘要： A storage cluster is provided. The storage cluster includes a plurality of storage nodes within a chassis. The plurality of storage nodes has flash memory for storage of user data and is configured to distribute the user data and metadata throughout the plurality of storage nodes such that the storage nodes can access the user data with a failure of two of the plurality of storage nodes. Each of the storage nodes is configured to generate at least one address translation table that maps around defects in the flash memory on one of a per flash package basis, per flash die basis, per flash plane basis, per flash block basis, per flash page basis, or per physical address basis. Each of the plurality of storage nodes is configured to apply the at least one address translation table to write and read accesses of the user data.
摘要翻译：提供了一个存储集群。存储集群包括在机箱内的多个存储节点。多个存储节点具有用于存储用户数据的闪存，并且被配置为在整个多个存储节点中分发用户数据和元数据，使得存储节点可以利用多个存储节点中的两个的故障来访问用户数据。每个存储节点被配置为生成至少一个地址转换表，其基于每闪存片基于每闪存片基于每闪存片基于每闪存片基，每闪存片基于每闪存片基基础或每个物理地址的基础。多个存储节点中的每一个被配置为应用至少一个地址转换表来写入和读取用户数据的访问。
