IBM System Storage N series Hardware Guide
The hardware includes the following features and benefits:
򐂰 Data compression:
– Transparent in-line data compression can store more data in less space, which
reduces the amount of storage that you must purchase and maintain.
– Reduces the time and bandwidth that is required to replicate data during volume
SnapMirror transfers.
򐂰 Deduplication:
– Runs block-level data deduplication on NearStore data volumes.
– Scans and deduplicates volume data automatically, which results in fast, efficient
space savings with minimal effect on operations.
򐂰 Data ONTAP:
– Provides full-featured and multiprotocol data management for block and file serving
environments through N series storage operating system.
– Simplifies data management through single architecture and user interface, and
reduces costs for SAN and NAS deployment.
򐂰 Disk sanitization:
– Obliterates data by overwriting disks with specified byte patterns or random data.
– Prevents recovery of current data by any known recovery methods.
򐂰 FlexCache:
– Creates a flexible caching layer within your storage infrastructure that automatically
adapts to changing usage patterns to eliminate bottlenecks.
– Improves application response times for large compute farms, speeds data access for
remote users, or creates a tiered storage infrastructure that circumvents tedious data
management tasks.
򐂰 FlexClone:
– Provides near-instant creation of LUN and volume clones without requiring more
storage capacity.
– Accelerates test and development, and storage capacity savings.
򐂰 FlexShare:
– Prioritizes storage resource allocation to highest-value workloads on a heavily loaded
system.
– Ensures that best performance is provided to designated high-priority applications.
򐂰 FlexVol:
– Creates flexibly sized LUNs and volumes across a large pool of disks and one or more
RAID groups.
– Enables applications and users to get more space dynamically and non-disruptively
without IT staff intervention. Enables more productive use of available storage and
helps improve performance.
򐂰 Gateway:
– Supports attachment to IBM Enterprise Storage Server® (ESS) series, IBM XIV®
Storage System, and IBM System Storage DS8000® and DS5000 series. Also
supports a broad range of IBM, EMC, Hitachi, Fujitsu, and HP storage subsystems.
