The Problem:
Islands of Block, File and Object level data
SAN-level Storage
OS-specific file systems on
block-based devices
Sharing requires file transfers
Provides “Context” for
Analytics of Social and Mobile

NAS encourages sharing
across social networks

share across desktops and
mobile

Why use IBM Spectrum Scale™
Extreme Scalability
Add or Remove nodes and
storage, without disruption
or performance impact to
applications
Universal Access to Data
All servers and clients have access
to data through a variety of file and
object protocols
High Performance
Parallel access with no hot spots
Proven Reliability
Used by over 200 of the top 500
Supercomputers
Survive any node or storage failure with
Distributed RAID and redundant components

No single-server performance
and bottleneck scaling limits
- NAS filers can be a bottleneck and
significantly impacts system
performance
No centralized metadata server
- Centralized metadata server can
be a performance bottleneck for
metadata intensive operations

Local Read-Only Cache
(LROC) caches the busiest
blocks of files on local flash
NSD Client
Local Flash on NSD Clients
Automatically handles the flash cache so data
is transparently available to your application
with very low latency and no code changes
Accelerates I/O performance up to 6x by
reducing the amount of time CPUs wait for data
Improves application performance while
keeping all the manageability benefits of
shared storage
Data is never stale
• Cache consistency ensured by
standard tokens
• Data is protected by checksum
and verified on read
Reduces Network Load
• Decreases the overall load on the IP network,
benefitting performance for others

IBM Spectrum Scale™ – Policy Management

Migrate/Recall Tape
File Placement
When new files are created, the
active policy assigns it to the right
pool – Flash, 15K, 10K or Nearline
disk
Files can be marked for having
2 or 3 replicas
Files can be encrypted with
specific keys
File Expiration
Delete files
automatically after they
are no longer needed
File Movement (ILM)
Move files between pools
Based on age, size, heat,
access frequently or other
criteria
File Movement (HSM)
Migrate files to an external
pool of tapes

Storage Approach: Carpeting versus Rugs
Area Rugs Approach
Some clients want tactical point products for
particular workloads or applications, specific
projects, groups or remote office/branch office
(ROBO)
Wall-to-Wall Carpeting Approach
Some clients want a strategic, enterprise-wide
storage solution for all of their workloads,
applications and servers.

Reduce Costs and Increase Availability
with Spectrum Scale Native RAID
Dedicated
RAID Controllers
Flash / Disk Enclosures
RAID RAID
Spectrum Scale Native RAID distributes data,
parity and spare space uniformly across all
drives of enclosure using either 8+2P or 8+3P
Erasure Coding.
This distribution reduces the rebuild or disk
failure recovery process overhead
compared to conventional RAID
Critical rebuilds of failed full multi-
terabyte drives can be accomplished
in minutes—rather than hours or even
days when using traditional RAID
technology

OpenStack & Spectrum Scale
• OpenStack (as of Havana release) includes a Cinder driver
• Giving architects access to the features and capabilities of the industry’s
leading enterprise scale-out software defined storage
• With OpenStack on Spectrum Scale, all nodes see all data
• Copying data between services, like Glance to Cinder is minimized
or eliminated
• Speeding instance creation and conserving storage space
• Rich set of data management and information lifecycle features
• Efficient file clones
• Policy based automation optimizing data placement for locality or
performance tier
• Industrial strength reliability, minimizing risk
• Cinder driver provides resilient block storage, minimal data copying between
services, speedy instance creation and efficient space utilization
Cinder Integration
Swift Integration
• Consolidate File and Object under a single shared storage infrastructure.
• Simplifies data management:
• Global namespace eliminates the physical client-to-server mappings
• Ideal platform to perform common storage management tasks, such as
automated storage tiering and user transparent data migration
• Flat namespace eliminates the hassle of organizing data in a hierarchical
namespace
