Why Store Data in an Open Format?
• How Much Confidence Do You Have in Your Archive
Application?
• How Do You Get to Your Data if the Application Goes
Away? Say after 100 years.
• Have You Written Your Data in an Open Format?
• Hint: There is no such thing as an Open backup format!
Oracle Statement of Direction
Oracle is committed to the continued development of archive
solutions based on open formats
LTFS
WHAT IS IT?
WHAT MAKES STORAGE
SELF DESCRIBING?
When a file and the index that
describes that file are stored
together

WHAT IS UNIQUE
ABOUT SELF
DESCRIBING FILES?
WHY DO WE WANT
FILES TO BE
ACCESSIBLE?
TWO REASONS:
1 - Easily share files
2 - Retrieve files in the future
FILE
Self Describing Files are
independent of the OS and the
software used to create them
WHY DO WE WANT
SOFTWARE
INDEPENDENCE?
Freedom to access files
without proprietary

What are the Open Formats?
The Linear Tape File System (LTFS) & TAR are open format
specifications for storing files and an index of those files together
on tape, just like disk & flash
TAR
LTFS
• Open
 Open
• Self Describing
 Self Describing
• 30+ Years of Development
 Introduced in 2010
• Standard
 Standardization in Progress
• Multiple Index Access
 Single Index Access
How Does LTFS Store Files & the File Index Together?
• Tape must be LTFS formatted
• LTFS formatted tapes have 2 partitions
•1st partition for the file index
•2nd partition for the files
 LTO-5 was the 1st generation LTO media to support partitions

NDA:
Coming 2013 @ OOW:
Oracle’s StorageTek LTFS, Library Edition
What are the limitations of LTFS, Open Edition?
• To see the file metadata, the tape must be mounted
• Only one tape can be mounted at a time
• You have 10,000 tapes, which one do I want?
What Tape is My File On?
What is StorageTek LTFS, Library Edition?
LTFS, Library Edition provides a file system
interface to a tape library through POSIX,
CIFS or NFS commands, just like disk or flash
But, also addresses the “What Tape(s) are my
files on” problem…
How Does LTFS-LE Expose a standard
Interface to Tape Libraries?

LTFS Library Edition
Summary:
• Powerful new tool to enhance the usability of tape.
• But, LTFS is just infrastructure. Archives require
upper level S/W to ingest, index, move, protect,
access etc. etc.
• The wide-spread adoption of LTFS will be driven by
the ISV community, not by tape vendors.

 Oracle Plans: Axiom and ZFSSA
Is it all about Flash?
 You would sure think so by listening to all the analyst
and self-appointed pundits!
 Sure, it’s great stuff: Eliminated Seek and Latency,
helps to close the gap between nano-seconds (Server)
and milliseconds (Disks)
 But it’s pricey (8-10X HDD’s) and it wears out
• Flash is not going to catch HDD prices any time soon!
Is it all about IOPS, Bandwidth and Capacity?
The “My Dad can beat up your Dad” theory of Sales.
 It used to be, but not anymore
• 4 TB 3.5” SAS HDD = 4 Million IBM 3330 disk packs
• 16 Gbit FC = 1066 IBM S/370 Block Multiplexor Channels
• 1 Million IOPS was impossible 10 years ago, now it’s
commonplace
 Who really gives a damm anymore?
 So what is it all about?
People and Money
 It’s really about money:
• “Stuff” is cheap, people are not.
• “Healthcare” for Stuff is a whole lot cheaper than Healthcare for
people
• “Stuff” does not take vacations, cause HR problems, goof-off,
make stupid mistakes etc.
 The real value add of future storage has to be about
maximizing the effectiveness of the most expensive
resource: People
Wouldn’t it be nice if storage could:
 Accept a single command from an application and
provision itself, locate all paths to the application,
constantly self-tune itself as workloads change, do
whatever is necessary to protect data, never allow
silent corruption etc. etc.
 This is what Oracle is working on right now.
• The power of developing both hardware and software has never
been greater than right now.
Interesting Comments:
“Our goal is to eliminate, to the greatest extent possible, all
People from the day to day operation of our data centers. We
simply cannot afford the TCO of humans anymore.”
Storage CTO Ebay & PayPal
“We simply can’t run a competitive service business which relies on
significent human interaction to manage the equipment we host for
others and/or the equipment we own that hosts our managed service
offerings.”
SVP - Rackspace
The Future?
 8.5% Unemployment; the New Normal.
 “Any Storage sale under a Petabyte should probably go
through the Channel.”
• Executive at a very large Computer Company
 “Silicon Valley adding jobs while the rest of California
stagnates”
• 2012 California “State of the State” report
