Abstract

A storage system includes a first and second control modules (CMs) connected to a client and a storage module over a communication fabric. In response to a data fragment written to the storage module, the first CM is to create a table of contents (TOC) entry in a TOC page maintained in a first storage partition of the storage module, update its FTL map, determine whether the TOC page contains a predetermined number of TOC entries, and in response to determining that the TOC page contains the predetermined number of TOC entries, send a control signal to the second CM via an inter-processor link. In response to the control signal received from the first CM via the inter-processor link, the second CM is to copy the TOC page from the first storage partition to a memory associated with the second CM to allow the second CM to update its FTL map.
