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 transactions
File-level Storage� NAS encourages sharing
across social networks
� Desire for file sync-and-share across desktops and mobile
� HDFS requires transfer (ingest) from other sourcesJFS2

Object-level Storage� New Web and Mobile apps

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
4
© Copyright IBM Corporation 2015
� 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

IBM Spectrum Scale™ – Local Read-only Cache
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
� Accessed files are automatically recalled back to internal pool of flash or disk

Reduce Costs and Increase Availabilitywith Spectrum Scale Native RAID
DedicatedRAID 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
