Active storage using object-based devices

Abstract

Abstract-The increasing performance and decreasing cost of processors and memory are causing system intelligence to move from the CPU to peripherals such as disk drives. Storage system designers are using this trend toward excessive computation capability to perform more complex processing and optimizations directly inside the storage devices. Such kind of optimizations have been performed only at low levels of the storage protocol. Another factor to consider is the current trends in storage density, mechanics, and electronics, which are eliminating the bottleneck encountered while moving data off the media, and putting pressure on interconnects and host processors to move data more efficiently. Previous work on active storage has taken advantage of the extra processing power on individual disk drives to run application-level code. This idea of moving portions of an application's processing to run directly at disk drives can dramatically reduce data traffic and take advantage of the parallel storage already present in large systems today. This paper aims at demonstrating active storage on an iSCSI OSD standards-based object oriented framework.

Oasa: An Active Storage Architecture for Object-based Storage System

“…3, the input and output of a function can be both network client and disk. Similar to the previous work 13,14 , data flows in pattern 1 and pattern 3 are as same as that in the normal OSD WRITE and READ command. On this occasion, intelligent operation such as data filter (e.g.…”

“…In the existing OSD standard, a client can access the data of one user object with one OSD command, thus these earlier work 13,15 based on the existing OSD standard in fact provides only an one-to-one association between object and function. In this paper, we extend the association to an many-to-one association: in one EXT CMD one user function is able to process multiple objects.…”

“…In order to promote the development of objectbased storage technology, several work tried to integrate the active storage technology into the objectbased storage technology based on the T10 OSD standard 15,21,13 . Recently, Xie et al presented an object-based active storage framework with a preliminary security solution 23 .…”

Active Flash: Out-of-core data analytics on flash storage

“…Earlier attempts to combine computation and storage have focused on adding application programmability on diskresident CPUs [42] and parallel file system storage nodes [21]. This Active Storage approach has drawn renewed interest in recent years with the commercial success of Netezza [34], a specialized "data warehouse" system for analyzing data from business applications.…”
