Who am I?
VP & GM, Americas at WhipTail Benefit from joining very early Citrix & Symantec (VERITAS)
background Humbly attempt to be student
CONFIDENTIAL & PROPRIETARY 3
What this Presentation is NOT Sales-oriented Consumer market related Marketing-fluffed
CONFIDENTIAL & PROPRIETARY 4
What this Presentation IS
History of solid-state Types of solid-state Early adoption Current offerings How it’s panning out What the future holds
For the enterprise…
CONFIDENTIAL & PROPRIETARY 5
Why Are We Here Today?
CONFIDENTIAL & PROPRIETARY 6
Types of Solid-State Storage:DRAM
History Invented 1978 at IBM $8.8mm/GB! Mainly memory Enterprise shared-
storage appliances hit the market in the 90’s
Pros/Cons Pros
Absolute fastest Cons
Most expensive/GB Volatile Mainly offered via direct
attached storage (DAS) architectures
CONFIDENTIAL & PROPRIETARY 7
Types of Solid-State Storage:Flash
History Launched 1987 by
Toshiba Thumb drives circa
2000 Apple iPhone 2007 Now out-ships DRAM
8X
Pros/Cons Pros
Cheaper Fast Non-volatile Capacity
Cons All flash wears out Not bit-addressable =
writes slow Larger capacities =
worse endurance
CONFIDENTIAL & PROPRIETARY 8
Two Types of Flash
SLC (Single Level Cell) Pros
Natively faster Natively more durable
Cons 10X more expensive Lower capacities Lower supply Wears out
MLC (Multi-Level Cell) Pros
Larger capacities Cheaper Still fast Mass produced
Cons 1/10th the durability Natively slower
CONFIDENTIAL & PROPRIETARY 9
Why Consider SSD At All?
CPU & memory no longer the bottleneck
HDD as fast as it’s going to get Moore’s Law Virtualization On-demand world Storage performance in spotlight
CONFIDENTIAL & PROPRIETARY 10
Performance Evolution from Traditional Vendors Hard Disk Drive (HDD) tricks Cache Trays of SLC SSD SLC flash as cache Auto-tiering Evolutionary path mainly driven by
physical limitations of flash Ultimately all became “Hybrid Arrays”
CONFIDENTIAL & PROPRIETARY 11
Performance Evolution from Start-Ups Leveraging SSD Server-side DAS “In-the-Middle” caching appliances Hybrid Arrays “Mix-of-the-above” solutions 100% solid-state storage arrays This is your current landscape
CONFIDENTIAL & PROPRIETARY 12
Server Side DAS
Players SSD
Hitachi, STEC, Toshiba, Intel, Samsung, SanDisk, OCZ, Apple, etc.
PCIe Fusion IO EMC (Project Lightning) Others
Pros/Cons Pros
Performance closest to workload
Cons Expensive Management nightmare Single point of failure Consumes server
resources Performance island Wasted capacity
CONFIDENTIAL & PROPRIETARY 13
“In-the-Middle” Caching Appliances
Players Dataram Gridiron Avere
Pros/Cons Most incumbent arrays
now do this Putting small company
solution in front of multi-million dollar investment
Helps reads only Expensive In-band
CONFIDENTIAL & PROPRIETARY 14
Hybrid Storage Arrays
Players Every major storage
player now a hybrid Nimble Xiotech
Pros/Cons Pros
Leverage existing investment
Manage one array One source of support
Cons Performance limited Expensive Not a “top speed”
solution – doesn’t close performance gap
One demanding workload ruins it for everyone
CONFIDENTIAL & PROPRIETARY 15
“Mix-of-the-Above” Contraptions
Players Tintri Atlantis
Pros/Cons Pros
? Helps with IO problem
some? Cons
Too much technology Blame storming Management nightmare Impacts everything More room on this
slide?
CONFIDENTIAL & PROPRIETARY 16
100% SSS Arrays
Players DRAM/SLC Hybrid
Violin Kaminario Texas Memory Systems
All Flash WhipTail Nimbus
Pros/Cons Pros
Top speed performance (15X-30X Hybrid Arrays)
Focus on closing gap Pioneering
Cons Individually managed Fabric attached? HA/BC/DR? Write speed? Wear?
80% of the IO resides on 10% of the capacity…

Future of SSD
SLC will go away (VHS & Beta) Server side SSD will continue DAS, SAN, NAS, and now…SSA Two tiers, no auto-tiering All “in-the-middle” and “mix-of-the-
above” solutions will dissipate and go away
CONFIDENTIAL & PROPRIETARY 19
Caveat Emptor: “1 Billion IOPS!” Don’t believe everything you read 2012 #1 SPC-1 storage benchmark = 520k IOPS,
$3.8mm, 2k+ HDD Require an evaluation or third party performance
lab validation report Ask about block size, Ask about read/write Ask about Internal, DAS fabric connectivity With parity? Match your requirements
CONFIDENTIAL & PROPRIETARY 20
Future of Use Cases
Past/Present VDI operating Systems Limited Oracle, SAP,
SQL, Exchange OLTP Federal/DoD
supercomputer-type stuff
Future Mainstream multi-
tenant platform use Virt. of Tier 1 apps ALL Tier 1 apps BI/OLAP HPC metadata, check-
pointing, out-of-core Portions of Big Data Batch Code development
CONFIDENTIAL & PROPRIETARY 21
The “Star Trek” Future
Phase-change memory - Samsung Memristors - HP Atomic storage – IBM Years (decades?) away from large
scale manufacturing Flash closes the datacenter
performance gap for now
