The Big Data Momentum
The “Arab Spring” of Enterprise Computing
It’s massive
Mobile, RFID, surveillance cameras, genomics, click stream, PoS cash
registers, search engines, browser cookies, logs, …
It’s about people, and people-to-people
It’s swift
It’s about breaking away

The “Arab Spring” of Enterprise Computing
It’s massive
It’s about people, and people-to-people
Sentiments, risks, terror watch, intent, social interactions, buying behavior,
likes-dislikes, tastes, sharing, trending
It’s swift
It’s about breaking away

Flattening of Infrastructure: No SANs

Breaking Away
The mutiny that revolutionized analytics
“The practitioners of big data are hostile to shared storage. They
prefer server-attached storage… The perception of SAN and
NAS is that they are slow, complex, and above all, expensive.
These qualities are not consistent with big data analytic systems
that thrive on system performance, commodity infrastructure, and
low cost.”
- Wikipedia (“Big Data”)

Flattening of Infrastructure: NoSQL, No Database, No DBAs
DW  MapReduce, SQL  REST/HTTP

Power to the People Who Matter
Massive democratization of infrastructure
Autonomy, independence, access
DevOps takes charge
Application owners become paramount

Flattening of Infrastructure: A Brief History of the Post-SAN Era
Infrastructure is totally flattened… and simplified
SAN goes away
Transactional database and SQL go away
Monolithic systems are banned
Grow-as-you-go clusters are in vogue
Network topologies are flattened

12. KEY CONCEPTS
Massive-Parallelism, MapReduce, NoSQL

13. 013
NUTANIX INC. – CONFIDENTIAL AND PROPRIETARY
Massively Parallel Architecture
Embarrassingly Parallel Computing
“Just-throw-a-server” approach:
Commodity off-the-shelf hardware
Works beautifully if the data access is local
Everything grows: compute, (virtual) network, storage capacity,
IOPS, MB/s

14. 014
NUTANIX INC. – CONFIDENTIAL AND PROPRIETARY
Massively Parallel Architecture
Nutanix’s “Embarrassingly Parallel” Filesystem
Build to scale from “merchant-
grade” to “enterprise-
grade”:
The largest and fastest
filesystem ever built for
virtualized environments
Industry’s first unified and
converged virtualization
stack

15. 015
NUTANIX INC. – CONFIDENTIAL AND PROPRIETARY
NoSQL
Embarrassingly Parallel Key-Value Stores

16. 016
NUTANIX INC. – CONFIDENTIAL AND PROPRIETARY
NoSQL
Nutanix’s use of NoSQL
To store metadata that massively scales
Metadata: to answer “where is user’s data located” question
Present on every cluster node
Rebalances when nodes are added or removed
Lock-less: No database-like transactions for updates
Distributed consensus on updates
We’ve forked off Cassandra to build our own NoSQL store

17. 017
NUTANIX INC. – CONFIDENTIAL AND PROPRIETARY
MapReduce
Divide-Conquer-Sort-Shuffle-Collect
“Just-throw-a-server” approach:
Embarrassingly Parallel problem
solving
Click stream analysis example:
Sum of all clicks, grouped-by IP
addresses
Top 10 IP addresses with most
clicks: Pipelining

18. 018
NUTANIX INC. – CONFIDENTIAL AND PROPRIETARY
MapReduce
Nutanix’s use of MapReduce
We do *not* use Hadoop, an open source MapReduce framework
We built our own framework
So what is it used for?
Our metadata is partitioned on all the nodes
We constantly need to do a lot of “heavy-lifting”:
run metadata heuristics on access patterns
rebalance storage after node add/remove
waterfall data between flash and spindle tiers
heal the clusters during hardware failures
garbage-collect deleted vDisks
sever parent-child links for snapshot’ed vDisks

19. VDI’s Takeaway
Freedom is refreshing

20. 020
NUTANIX INC. – CONFIDENTIAL AND PROPRIETARY
VDI 2008-’11
The one that couldn’t break away
Legacy infrastructure
Ugly retrofitting: square-peg-in-a-round-hole
Too much consensus-building
Too many people in the room, too many to appease
Lack of rapid prototyping
Pilot was not the same as production
Application owners had little to no power
Note: VDI is an “embarrassingly-parallel” problem, if storage is kept local

21. 021
NUTANIX INC. – CONFIDENTIAL AND PROPRIETARY
SAN-less VDI
Bringing the disk back to the PC
Caching is local
Flash is local
NFS is simple
Dedup is massive
User-data (D:) is safe
Pilot _is_ production
XenApp is complementary
Shares the same infrastructure
Freedom is refreshing… isn’t that what BYOD is all about?!
