Abstract
Official abstract text for this publication.
Mechanisms are provided for extending cache for an external storage system into individual servers. Certain servers may have cards with cache in the form of dynamic random access memory (DRAM) and non-volatile storage, such as flash memory or solid-state drives (SSDs), which may be viewed as actual extensions of the external storage system. In this way, the storage system is distributed across the storage area network (SAN) into various servers. Several new semantics are used in communication between the cards and the storage system to keep the read caches coherent.
First claim
Opening claim text (preview).
What is claimed is: 1. A computer program product comprising a non-transitory computer readable storage medium having a computer readable program stored therein, wherein the computer readable program, when executed on an extended cache card, causes the extended cache card to: responsive to server data processing system performing a write operation to write a first portion of data to an external storage system, store a copy of the first portion of data in a non-volatile memory of t…
