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 additional
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.
MetroCluster
– Offers an integrated high-availability/disaster-recovery solution for campus and
metro-area deployments.
– Ensures high data availability when a site failure occurs.
– Supports Fibre Channel attached storage with SAN Fibre Channel switch; SAS
attached storage with Fibre Channel -SAS bridge; and Gateway storage with SAN
Fibre Channel switch.
MultiStore
– Partitions a storage system into multiple virtual storage appliances.
– Enables secure consolidation of multiple domains and controllers.
NearStore (near-line)
– Increases the maximum number of concurrent data streams (per storage controller).
– Enhances backup, data protection, and disaster preparedness by increasing the
number of concurrent data streams between two N series systems.
OnCommand
– Enables the consolidation and simplification of shared IT storage management by
providing common management services, integration, security, and role-based access
controls delivering greater flexibility and efficiency.
– Manages multiple N series systems from a single administrative console.
– Speeds deployment and consolidated management of multiple N series systems.
