“IDC estimates that the total amount of digital information created, captured and replicated will grow at a rate of 58% per year – reaching 1,610 Exabytes in 2011”

structured data

unstructured data 80 % of all digital data is unstructured

Increasing cost to manage growing storage resources

Unstructured data resists categorization, utilization, and reuse

Explosion of Unstructured Data

Trained Administrator

Customer Challenges

Fork lift upgrade

Expensive

Getting smart to address the problem

Simple to manage

Easy to Scale

Economics of Scale

Innovation and better storage economics

What is OpenStorage?

Freedom of choice at every level of storage stack

OpenStorage represents a growing part of the existing Storage ecosystem. Open storage will account for $10.6B of the $90B Storage market.

Open Storage at Stanford University

How we got here

Commercial and non-commercial file servers

Tape Backup

Data Growth

Why buy today when its cheaper tomorrow

User Expectations

Too Many Choices

2nd Tier Storage

Disaster Recovery

Tape is dead

Commodity growth curve

Snapshots

The New Backup(Amanda and Crashplan)

VMs storage reqs

Reliability

Performance

Snapshot integration

1st Tier Storage

Prime Time

1st Tier Setup

Get your feet wet with 2nd tier storage

HA possible, but at some cost

Go through your failure scenarios

Expectations may warrant vendor/VAR/SI

Storage Growth == Commodity Storage Growth

Growth At Stanford

Get to the Meat

Best PracticesStanford ActiveDirectory is typically

non-standard: Use the “gateway” approach

NFSv4/Kerberos a work in progress

RAID10 is best

RAID5/6/Z1/Z2+ for 2nd Tier only

More drives > larger drives

Sweet spot == 1TB?

Evil Practices

Hardware RAID

Cloud Directions

First move is to 3rd PartiesSecond stage is external services leveraging other

services (DropBox)Third stage is

building in-house clouds
