The Oracle Storage Story, Now and Tomorrow
Chris Wood
Director of Product Management, Axiom LOB
A simplified History of Sun/Oracle
Storage
• In 1999 Sun acquired MaxStrat (and me in the
process) to get it’s first real RAID array. The famous
(infamous) T3. (Project Purple)
• Sun was not skilled in acquisitions; Sun managed to “incent”
90% of the MaxStrat development team to quit within the first
90 days.
• Leaving a half completed program with no skills to complete
it.
• About 2 years later the T3 finally shipped with about ½ the
features it was supposed to have and little or no RAS.
• We sold over 36,000 of them and then it started to break…
• Everything hit the fan – I got good at ducking.
If at first you don’t succeed…
• Buy another company with Magic Technology: Pirus
networks (2002)
• Pirus had a distributed architecture crossbar virtualization
engine that was supposed to do NAS, SAN, offer any to any
connectivity, rich data services, fast as all get out and be the
industries first totally virtualized array. (6920)
• Unfortunately, this did not happen and the remnants were sold
off to LSI/Engenio for pennies on the dollar
• Sun also bought LSC in 2001 and obtained SAM-QFS
but had no clue what to do with it. (The “Box” Mentality)
• Now Sun had no competitive storage offerings; Some cool
storage S/W but no idea how to exploit it, so what to do?
Give up, and OEM something that works
• Sun OEM’s “Big Fish” from HDS – The 99xx line
• Sun OEM’s “Little Fish” from LSI – The 6xxx line.
• Both products work just fine, so Sun decides to develop it’s
own UI CAM (Common Array Manager) vs. use the well
respected HDS High Command and LSI’s SANtricity.
• In keeping with past failures, CAM was universally disliked by
customers, slow, buggy and short on function; otherwise a
great product.
• There was one other problem: It’s very hard to make
money on OEM’d products – Especially if you have
daily channel conflict with your major vendor HDS.
• Now What?
Fishworks
• Sun finally asks the right question: What exactly is
storage?
• Disks and Enclosures: Commodity, low value “stuff”
• Controller Hardware: Memory (DRAM), microprocessors, I/O
ports and a ton of software – A server for instance – We make
those!
• What Glue is missing?
• File System, Volume Manager, RAID code etc. – ZFS – Gosh,
we own that also…
• Management UI – Fishworks and D-Trace Analytics
• Decision: Let’s build the Glue and tie the other parts
that we already have together – Thus was ZFSSA
born.
Today
• Oracle has two great storage offerings: Axiom 600
and ZFSSA – Similar but different, more on this later
• Oracle has the premier tape offering in the world,
hands down
• Oracle has re-discovered SAM-QFS – There’s still
nothing quite like it in the world.
• Oracle has doubled-down on storage and will
announce complete product refreshes for both the
Axiom and the ZFSSA at Oracle Open World with
availability this year. Sneak peak coming.

Jim Cates on Tape…
His response to my comment: “the SL8500 is really cool”
• The T10000C tape drive is also another fairly sophisticated product. The
tape is 5 microns thick and we do fast search down tape at about 12
m/s (26 mph). The drive writes ~ 3 micron data tracks on tape at roughly
11 mph to a placement accuracy of tenths of microns. We place 3584
tracks on 1/2 inch tape using 32 data channels operating in parallel.
• Oracle designs everything for this drive including the recording head film
stack, servo pattern, tape path, rd/wrt channels, compression/encryption
algorithm, analog/digital chips, etc.
• We arguably control the largest breadth of dimensions associated with
a product. The recording heads have films measured in angstroms. The
media length is about 1 kilometer. This is a difference of about 13
orders of magnitude.
• The rise time of the head and channel is specified in nanoseconds. The
media shelf life is 30 years. This difference spans 17 orders of
magnitude.
• CW Comment: Tape is way cool!
But Tape is Dead…
• Every analyst says tape backup is declining – And
they are correct!
• D2D (VTL’s etc) are winning: Faster, Deduplication, Sex
Appeal, whatever.
• Then along came Government Regulations,
Politicians and Lawyers. Thank God!

Why Tape: Economics of Tiered Storage
• Tape is the Foundation: Most of the Data Stored at the Lowest Cost
5%
15%
Current (7-30 days) : Flash/Performance Disk
• Frequent changes
• Immediate access
• Instantaneous protection
Recent (30-90 days) : SAS/SATA
• Infrequent changes
• modifications change classification to
“Current”
• Slight access delay acceptable
Archival (>90 days) :
Tape
• Very infrequent / no changes
80%
• Offsite / offline / nearline protected
Result: Tape is growing,
Backup is not
Analysts: Digital Archive Market
Tape is the largest tier
Archive Capacity and Revenue: 2009-2017 (EB and $M)
• Storage for archive and
retention is a $3B Market
growing to over $7B in
2017
• Use case for archive
storage is becoming
distinct from primary or
backup use case
• Tape is established as
primary storage tier for
long-term archive
retention
IDC Market Analysis. Worldwide Archival Storage Solutions Forecast: Archiving Needs Thrive in an Information-Thirsty World. (IDC #230762)
Press: Tape
“Archive, legislation, need for off-site data storage, disaster
recovery, dealing with massive data quantities all mean there is a
place for tape. Even as semi-primary storage, tape can have a role
to play.”
Clive Longbottom in Dave Bailey’s column, Computing
“(Tape) gives true offsite vaulting for disaster recovery, and requires
much less power and cooling. We believe tape will remain viable for
the foreseeable future.”
Robert Amatruda, IDC, in Iain Thomson’s column, V3

Function
Quality of
Service
Application prioritization and
contention management that
enables multiple applications to
efficiently co-exist on the same
storage system
Modular
Architecture
Distributed
RAID
Ability to dynamically scale
both performance and capacity
by independently adding
Slammers (up to 4) and Bricks
(up to 64)
Achieves superior scalability
and performance even during
drive rebuilds by moving RAID
local to storage enclosures
Benefits
Applications are assigned I/O
resources according to their
business value and not relegated to
‘first come first served’
Increases overall efficiency and
utilization of the storage system
Maximum performance/utilization
regardless of size of configuration.
Ability to grow and rebalance the
storage pool based on changing
business environments
Ensures predictable performance
scaling with capacity add.
Higher reliability by localizing the
drive rebuild process to the storage
enclosure and reducing RAID
rebuild window
