The Future of Storage, with Tony Pearson

The storage landscape is changing as a result of the convergence of virtualization, improvements in energy
efficiency, cloud computing and users' insatiable demand for data. With adoption of server virtualization,
storage is taking over as fastest-growing part of a typical company's information infrastructure.
New technologies are changing the way organizations manage their storage assets. Flash storage delivers
more flexibility in creating hierarchical tiers to meet different demand priorities. Storage virtualization enables
businesses to increasingly treat all their storage assets as a single pool. Data deduplication can significantly
reduce redundancy. Cloud storage is another intriguing option, providing the capability to dynamically move
storage assets to a shared model.
These and other advances require IT organizations to rethink the way they classify their storage assets. In
this presentation, Tony Pearson outlines the seismic forces that are reshaping the storage landscape. You'll
learn:
– How the shift in roles assigned to each storage type can be used to optimize storage and retrieval
efficiency;
– How to take advantage of multiple tiers of storage via automated and policy-driven methods;
– How to apply the convergence of data center networking technologies - including FCoE, iSCSI, NFS
and CIFS protocols, as well as voice and video - to your environment;
– The importance of cloud computing, and the ways storage can participate in this new scheme.

Easy Tier achieved better performance in 50 percent less floor space and
40 percent less energy. Save up to $100,000 in power and cooling for
roughly 75 TB of usable data over three years.



Enhancing Storage Efficiency

Data deduplication is a
method of reducing storage C B A C B A
needs by eliminating
duplicate copies of data. C C
A B A B
– Store only one unique instance A
of the data
B B
A A A
– Redundant data replaced with
pointer to the unique instance

Real-Time Compression is a method of reducing
storage needs by changing the encoding scheme as the
data is being read and written.
– Short patterns for frequent data
– Longer patterns for infrequent data.
– Can achieve 20 to 80 percent reduction in storage capacity.

Origins of Cloud Computing

“ If computers of the kind I have advocated become
the computers of the future, then computing may
someday be organized as a public utility just as the
telephone system is a public utility... The computer utility
could become the basis of a new and important industry.
„
Cloud Computing
—John McCarthy, MIT Centennial in 1961

Time-Sharing

In the 1960s and 70s, several
companies provided time-sharing
services as service bureaus



Cloud – A Disruptive New Paradigm?

“Clouds will transform the information technology (IT) industry…
profoundly change the way people work and companies operate.”

Cloud computing is a pay-per-use model for enabling 2010
network access to a pool of computing resources that can
be provisioned and released rapidly with minimal Cloud Computing

What is Cloud Storage?

Ephemeral Storage
• Typically boot volumes
Three types • Goes away when VM
of Cloud Storage is shutdown

Hosted Storage
• Production
• Backups
• Archives
Persistent Storage
• Persists across VM reboots
• Can be shared between VMs



IBM Smart Business Development and Test Cloud
32 x 168 x 10 = 53,760 VMs per SONAS
Virtual Machines
• Up to 32 VMs per iDataPlex server
• Used for ephemeral and persistent storage needs
Hypervisor • Each file in standard 256GB, 512GB, or 2TB size
• Appears as “Block Storage” to the virtual machine

iDataPlex
• Up to 10 iDataPlex systems per SONAS disk system
• Each iDataPlex has 168 servers sharing 1 file system

Scale-Out Network Attached Storage (SONAS)
• Up to 11 PB of usable storage
• Read/Write access via CIFS, NFS, HTTP, FTP, SCP
• Policy-driven placement, movement and expiration



Cloud Prediction from Sun CTO Greg Papadopoulos

A "neutron star collapse of data centers"
–It won't make sense for businesses to build
their own data centers.
Hosting providers will bring "brutal efficiency" for
utilization, power, security, service levels, and
idea-to-deploy time.
–A half dozen very large cloud infrastructure
providers and a hundred or so regional
providers
Look more like the banking world
–Customers will trust service providers with
their private data as they do banks with their
money.
