System and Methods for Performing Embedded Full-Stripe Write Operations to a Data Volume With Data Elements Distributed Across Multiple Modules

摘要

A data storage system and methods for managing data to be transferred between a host and a data volume distributed across solid state storage modules are disclosed. A storage controller couples the host to the data volume and manages data transfers to and from the logical volume. The storage controller receives a set of parameters that define how an array of blocks and chunks of buffered data will be distributed across solid state storage modules. The storage controller receives and buffers data to be stored and transfers the same when the capacity of the buffered data will fill a set of arranged stripes in the defined array in a single write operation.

1. A data storage system, comprising:
a controller comprising processing logic that is configurable to define and manage data transfers to and from at least one logical volume to be exposed to a host device, the data transfers as managed by the controller including data aligned for a single write operation to a set of arranged stripes in a defined array distributed across N solid state storage modules; and a cache memory coupled to the controller for storing data to be written to the data volume.
