• Heterogeneous storage access—Designed to provide networked storage capable of consolidating NAS and iSCSI storage requirements
  
• FCP support—Designed for operation in Fibre Channel SAN environments
  
• Instant backup and instant recovery—Supports disk-based backup, with file or application-level recovery in seconds with Snapshot™ and SnapRestore® software features
  
• Simple replication and disaster recovery—Designed to provide an easy-to-deploy mirroring solution that is highly tolerant of WAN interruptions
  
• Management simplicity—Designed to enable on-the-fly provisioning; self-diagnosing systems with automated replacement parts delivery; self-service file recovery for end users
  
• Cost effective—FlexVol® can double storage utilization, and both block and file storage can be consolidated into a single affordable

Corporate workgroups, distributed enterprises and small-to-medium-sized companies increasingly seek to network and consolidate storage to improve availability, share information, reduce costs and protect and secure information. These organizations require enterprise-class solutions that are capable of addressing immediate storage needs cost-effectively while providing an upgrade path for future requirements. Ideally, IT managers would like a maximum degree of flexibility to design the architecture that best supports the requirements of multiple types of data and a broad range of applications.

The solution: IBM System Storage N3700 storage system

IBM System Storage™ N3700 is designed to offer you fast data access with extremely low maintenance requirements for a highly capable data storage solution. The N3700 filer integrates storage and storage processing into a single unit, facilitating affordable network deployments. These advanced storage systems use a proven storage architecture and offer standard IBM System Storage N series elements, including integrated I/O, high availability via clustering and Fibre Channel and/or SATA disk drives. IBM System Storage N3700 models are designed to integrate easily into existing IT environments to deliver unified storage for organizations with NAS, IP SAN via iSCSI protocols, FC SAN via FCP protocols, or combined environments, making enterprise-level storage a realistic goal for company sites regardless of size or staffing.
