First Reaction: Stupid Question• Well, a silly question, at least.• It suggests that all archives are the same, but

we know better…– Active archive: data still referenced but seldom

changed– Deep archive: data rarely re-referenced and

never changed• Different kinds of archive suggest different

requirements from the archive platform: no “one size fits all”

Historical data, intellectual property,data retained for regulatory compliance,

conforming to an archive strategy…

Production data, usually files, with limited re-reference rates, stored economically…

Anyway, Disk is Already Used by Many Firms to Platform Data Archives

Foundation of the Case for Disk-Based Archiving

• Familiarity of the technology• Ease of deployment*• Data migration and copy support*• Improving disk capacity/performance• Availability of value-add data

reduction/compression technology *well, sort of, maybe

But Also a Few Drawbacks…• Acquisition cost (value-add software

is cost accelerator)• Bit error rate of disk• Energy consumption• Silo-ing and proprietary design (lock-

in costs/difficult migration)• Lack of data reduction standards• Poor hardware management

capabilities

Tape Provides an Alternative• Linear Tape File System

(LTFS)• BlackPearl and Object

Storage• BaFe tape coatings• Capacity, resiliency, economy

National Petascale Computing Facility’s Blue Waters supercomputer uses 380 PB of tape storage, 26 PB of disk…

Tape, too, has some Rough Edges• Unfamiliar to “millennials”• Access speeds can be an issue• File systems like LTFS

optimized for “long block” files, not small files

But Not Sufficient Cause to Count Tape Out…

• Even the de-duplicating disk array folks have agreed on this score…in the past, at least!

Time for Some Sanity• Archive is an application

with a “personality”• Rather than Disk vs Tape…• …Maybe All of the Above is

the better strategy!

What About Front-Ending Tape with a Disk Cache

• Remember Disk to Disk to Tape?

• Why not tier your archive:– Low cost, high capacity disk

for Active Archive– Tape for Deep Archive

Disk Makes a Good Tape Cache• Whether LTFS or BlackPearl

– In LTFS, disk cache can expedite access to tape-based files by spoofing access latency

– With BlackPearl, disk provides a preparatory area for coalescing objects into buckets before writing to LTFS tape…

“All of the Above”

• The best strategy– Matching infrastructure to data

access requirements and anticipated data growth

– Leveraging the complementarity of magnetic storage media technologies, even in “clouds”…
