IBM Tape Density Achievement – 35TB Tape

Tape’s Future is Strong

• Jan. 2010: IBM Research - Zurich recorded data onto an advanced prototype tape developed by Fuji Photo Film Co. of Japan

• Density of 29.5 billion bits per square inch -- about 39 times the data density of today's popular standard tape

• Could produce future tape cartridge holding up to 35TB

• New critical IBM technologies were developed:• Dramatically improved precision of controlling the position of the read-write heads• More than 25-fold increase in the number of tracks• New detection methods to improve the accuracy of reading magnetic bits• New low-friction read-write head

• Represents a step towards developing technologies to achieve tape areal recording densities of 100 billion bits per square inch and beyond

IBM scientist’s read-write tape device: new record in tape data density of 29.5Gbits / square inch



100 Gb/in2 Appears Achievable

Tape’s Evolving Role

Tape is an integral part of the storage hierarchy

Customers store 4-15X more data on tape than disk

Tape is low cost

Tape is intrinsically “On-Demand”

Tape is removable and portable

Tape provides high volumetric efficiency

Tape media has a long life

Tape is ideally suited for:

Information Lifecycle Management

Infrastructure Simplification

Business Continuance

Outline and Motivation

Disk technology: only moderate improvements in speed and latency– Growing needs for streaming analytics, requires high IOPS

– Growing need for massive digital data archival, requires low TCO

Solid-state memory technology is addressing the high IOPS segment more efficiently than disk

Currently Flash technology: What will come after Flash?

Tape has addressed, so far, the low TCO segment more efficiently than disk

Can it maintain its substantial cost/GB advantage over disk?



Cluster of servers with SCM DAS

Nearline and backup SATA, tape Tier 2

Tier 1

Impact of Disruptive Technologies on Tiered Storage

Tier 1: online transactional– DAS model (back to the future!)

– Clustering of SCM DAS• High performance for I/O-limited workloads• leverage huge local bandwidth by co-locating

processing and data• cluster servers to enable virtualization of server

and storage over converged fabric and link• Distributed RAID, no cache• Clustered software for advanced functions

and protection

Tier 2: nearline and backup– Large capacity SATA for nearline data

and backup of de-duplicatable data

– Power-efficient storage

Tier 3: offline and long-term archival– Power-efficient, high-capacity, low-cost tape

Offline and long-term tape Tier 3

Transforming Archival Storage Building the infrastructure for a new generation of archive

Current Archive: Data landfill

Store and forget

Not easily accessible, typically offline and offsite with access time measured in days

Not organized for usage, retained just in case needed

Readily accessible, access time measured in seconds

Indexed for effective discovery

Mined for business value

Emerging Archive: Leverage information for business advantage
