Storage Trends - Introduction
Broad-based reconfiguration of IT infrastructure based on public / private cloud computing
Advent of pervasive Flash Memory Disruption to compute/storage hierarchy Storage supplier industry in flux

Impact of Flash Memory Flash learning curve and economics are being driven by
smartphones and tablets
Unlike past new storage technologies of the past like optical and bubble, which were never able to compete with magnetic storage learning curve
We are at the very a long term trend (20 – 30 years) to replace rotating memory with flash memory
A look back to disk vs. tape is instructive
In the next 5 years, all laptops and most conventional desktops will switch to flash
In the next 5 years, all performance driven applications will switch to flash (or subsystems with significant amount of flash at the top of the hierarchy)

The Compute / Storage Hierarchy
Background Over the years storage migrated from direct attached to array based, to network
accessible. At the same time, storage as been deployed in well articulated hierarchies, with
fast disks (perhaps with small caches higher performance (flash or dram), medium speed disks, slow disks and tape (now used only occasionally for backup).
The STORAGE HIERARCHY is being replaced by the STORAGE GRADIENT of storage Flash appears as direct attached via PCIE (SSDs) Flash integrates more intimately with DRAM and the CPUs than it does with the
storage traditional storage infrastructure (Fusion) Flash also appears as
The primary storage (Pure) And the cache or hierarchical component of disk systems (EMC, NetApp, Nimble) And on the disk device itself (Seagate)
Industry Impact Important new companies
Fusion Nimble Pure (Pernix Data)
Subsystem companies EMC
An agile company that will acquire what it needs to stay relevant NetApp
WAFL, which has been the core IP of the company, is obsoleted by new technology The company has no track record of acquisition Is (and will) struggle with this transition
HP, Hitachi, etc.???
Primary suppliers Seagate
Enjoys scale and dominance, and is thinking about all of this Does not own Flash production, and is not in the subsystem business But could become the “Storage Tek” of the future
Western Digital, et al???
