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.

IOPS per Watt – A new Metric for SSD
� Solid-State Drives (SSD) are most appealing for random read-intensive I/O workloads
� Previous attempts to increase IOPS:
– Heavily use DRAM cache
– Short-stroke the spinning disk
– Stripe data across many spindles

Solid State Drives (SSD)
Solid State Drives (SSD) offer some interesting characteristics:
– More Reliable: 1% AFR vs. 3-8% for HDD– Lower energy consumption (Watts / Drive)– Faster read / Slower write destage
Best place to initially put this technology: drive-for-drive replacement inside servers
– Reduce outages, Improve Resiliency– Save 1500 Watts per server rack– Fast operating system reboot
Watts per TB tells a different story…– Spinning Disk can provide lower Watts/TB

Enhancing Storage Efficiency
� Data deduplication is a method of reducing storage needs by eliminating duplicate copies of data.
– Store only one unique instance of the data
– 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.

“Clouds will transform the information technology (IT) industry…profoundly change the way people work and companies operate.”
Cloud – A Disruptive New Paradigm?
Cloud computing is a pay-per-use model for enabling network access to a pool of computing resources that can be provisioned and released rapidly with minimal management effort or service provider interaction.

What is Cloud Storage?
Hosted Storage• Production• Backups• Archives
Ephemeral Storage• Typically boot volumes• Goes away when VM
is shutdown
Persistent Storage• Persists across VM reboots• Can be shared between VMs
Three types of Cloud Storage

IBM Smart Business Development and Test Cloud
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
iDataPlex• Up to 10 iDataPlex systems per SONAS disk system• Each iDataPlex has 168 servers sharing 1 file system
Hypervisor
Virtual Machines• Up to 32 VMs per iDataPlex server• Used for ephemeral and persistent storage needs• Each file in standard 256GB, 512GB, or 2TB size• Appears as “Block Storage” to the virtual machine
32 x 168 x 10 = 53,760 VMs per SONAS

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.
