IBM System Storage N series Gateway for SAN Storage Environments

Unify NAS, FC SAN, and IP SAN under a common architecture

Highlights

Improving storage utilisation and access

As enterprise storage requirements evolved from direct-attached to networked storage, many enterprises made significant investments in multiple storage architectures – direct-attached storage (DAS), SAN and NAS – to support the different access methods required by various business solutions. The result was often inefficient and underutilised storage environments. A critical IT management challenge is to optimise the use of existing storage to improve efficiency and ROI while continuing to support different access methods for different business solutions throughout the enterprise.

You may not be ready to replace existing storage systems with new, unified ones. Instead, you might be looking for ways to broaden the use of current infrastructure and improve ROI by provisioning SAN capacity for new business solutions requiring FC Protocol (FCP) and FC over Ethernet (FCoE), SCSI over IP (iSCSI) or NAS access and remote access.

IBM System Storage N series Gateway

The IBM System Storage N series Gateway product line is a network-based unified storage solution designed to provide IP and FCP access to SAN-attached heterogeneous storage arrays. The N6000 and N7000 series systems ordered with a Gateway feature code can help you make the most of the dynamic provisioning capabilities of Data ONTAP software across your existing FC SAN infrastructure to support an expanded set of business applications. The IBM N series Gateway is based on the Data ONTAP microkernel operating system, which is designed to unify block and file storage networking paradigms under a common architecture. The N series Gateway offers a comprehensive suite of advanced data management capabilities designed to help you consolidate, protect and recover mission-critical data for enterprise applications and users.

The IBM N series Gateway is designed to deliver the performance and capacity to meet access requirements for enterprises of all sizes. N series Gateway systems are intended to deliver industry-leading performance, offer terabytes (TBs) of managed capacity and be configured for simultaneous active/active access with secure failover across two independent systems in a cluster.

The N6000 and N7000 series Gateway product lines support the attachment to both N series EXN1000, EXN3000 and EXN4000 disk storage expansion units; IBM XIV Storage System, IBM System Storage DS8000, DS5000 and DS4000 series; as well as a broad range of EMC, Hitachi, Fujitsu, 3PAR and HP storage subsystems. You can now take advantage of the N series Gateway capabilities to help improve business efficiency and reduce data management complexity with a variety of storage subsystems.

IBM System Storage N series software features at a glance
Software Description Benefit
Advanced Single Instance Storage (A-SIS) Performs block level data deduplication on NearStore data volumes Volume data is automatically scanned and deduplicated, resulting in immediate space savings with minimal impact on operations
Data ONTAP N series storage operating system providing full-featured and unified data management for both block and file serving environments Single architecture and user interface simplify data management and reduce costs for SAN and NAS deployment
FlexCache Creates a flexible, horizontally scalable caching layer within your storage infrastructure that automatically adapts to changing usage patterns to eliminate bottlenecks Intended to improve application response times for large compute farms, speed data access for remote users, or create a tiered storage infrastructure that circumvents tedious data management tasks
FlexClone Instantaneously creates Logical Unit Number (LUN) and volume clones without requiring additional storage Accelerated test and development and storage capacity savings
FlexShare Prioritises 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 Redundant Array of Independent Disk (RAID) groups Allows applications and users to get more space dynamically and nondisruptively without IT staff intervention. Can enable more productive use of available storage and helps improve performance.

SnapMover Enables rapid reassignment of disks between controllers within a system without disruption Enables fast, non-disruptive load balancing within an active-active controller system
SnapRestore Rapidly restores single files, directories, or entire LUNs and volumes from any Snapshot backup Enables near-instantaneous recovery of files, databases and complete volumes
Snapshot Makes incremental, data-in-place, point-in-time copies of a LUN or volume with minimal performance impact Enables frequent, non-disruptive, space-efficient and quickly restorable backups
SnapValidator Maximises data integrity for Oracle databases Enhances Oracle database resiliency in compliance with Oracle HARD initiative
SnapVault Exports Snapshot copies to another N series system, providing an incremental block-level backup solution Enables cost-effective, long-term retention of rapidly restorable disk-based backups
SyncMirror Maintains two online copies of data with RAID-DP protection on each side of the mirror Protects against all types of hardware outages, including triple disk failure
Software Bundles** Simplified ordering of combinations of software features: Windows Bundle, Complete Bundle and Virtual Bundle Provide flexibility to take advantage of breakthrough capabilities, while maximising value with a considerable discount
