The IBM zEnterprise A system introduced a new and innovative redundant array of independent memory (RAIM) subsystem design as a standard feature on all zEnterprise servers. It protects the server from single-channel errors such as sudden control, bus, buffer, and massive dynamic RAM (DRAM) failures, thus achieving the highest System z A memory availability.(More)
— In this article we describe a class of error control codes called " diff-MDS " codes that are custom designed for highly resilient computer memory storage. The error scenarios of concern range from simple single bit errors, to memory chip failures and catastrophic memory module failures. Our approach to building codes for this setting relies on the(More)
