The Big Data MomentumThe “Arab Spring” of Enterprise Computing
It’s massiveMobile, 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

It’s about people, and people-to-peopleSentiments, risks, terror watch, intent, social interactions, buying behavior, likes-dislikes, tastes, sharing, trending
It’s swift
It’s about breaking away

Breaking AwayThe 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”)

Massive democratization of infrastructureAutonomy, independence, access

Breaking AwayFlattening of Infrastructure: A Brief History of the Post-SAN Era
Infrastructure is totally flattened… and simplifiedSAN goes awayTransactional database and SQL go awayMonolithic systems are bannedGrow-as-you-go clusters are in vogueNetwork topologies are flattened

KEY CONCEPTSMassive-Parallelism, MapReduce, NoSQL
013
NUTANIX INC. – CONFIDENTIAL AND PROPRIETARY
Massively Parallel ArchitectureEmbarrassingly Parallel Computing
“Just-throw-a-server” approach:Commodity off-the-shelf hardwareWorks beautifully if the data access is localEverything grows: compute, (virtual) network, storage capacity, IOPS, MB/s
014
NUTANIX INC. – CONFIDENTIAL AND PROPRIETARY
Massively Parallel ArchitectureNutanix’s “Embarrassingly Parallel” Filesystem
Build to scale from “merchant-grade” to “enterprise-grade”:The largest and fastest filesystem ever built for virtualized environmentsIndustry’s first unified and converged virtualization stack
015

NoSQLEmbarrassingly Parallel Key-Value Stores
016
NUTANIX INC. – CONFIDENTIAL AND PROPRIETARY
NoSQLNutanix’s use of NoSQL
To store metadata that massively scalesMetadata: to answer “where is user’s data located” questionPresent on every cluster nodeRebalances when nodes are added or removedLock-less: No database-like transactions for updatesDistributed consensus on updates
We’ve forked off Cassandra to build our own NoSQL store

MapReduceDivide-Conquer-Sort-Shuffle-Collect
“Just-throw-a-server” approach:Embarrassingly Parallel problem solving
Click stream analysis example:Sum of all clicks, grouped-by IP addressesTop 10 IP addresses with most clicks: Pipelining
018
NUTANIX INC. – CONFIDENTIAL AND PROPRIETARY
MapReduceNutanix’s use of MapReduce
We do *not* use Hadoop, an open source MapReduce frameworkWe built our own framework
So what is it used for?Our metadata is partitioned on all the nodesWe constantly need to do a lot of “heavy-lifting”:
run metadata heuristics on access patternsrebalance storage after node add/removewaterfall data between flash and spindle tiersheal the clusters during hardware failuresgarbage-collect deleted vDiskssever parent-child links for snapshot’ed vDisks
VDI’s TakeawayFreedom is refreshing

VDI 2008-’11The one that couldn’t break away
Legacy infrastructureUgly retrofitting: square-peg-in-a-round-hole
Too much consensus-buildingToo many people in the room, too many to appease
Lack of rapid prototypingPilot was not the same as productionApplication owners had little to no power
Note: VDI is an “embarrassingly-parallel” problem, if storage is kept local

SAN-less VDIBringing the disk back to the PC
Caching is localFlash is localNFS is simpleDedup is massiveUser-data (D:\) is safePilot _is_ productionXenApp is complementary
Shares the same infrastructure
Freedom is refreshing… isn’t that what BYOD is all about?!
