IBM System Storage N series Hardware Guide
1.1 Overview
This section introduces the IBM System Storage N series and describes its hardware
features. The IBM System Storage N series provides a range of reliable, scalable storage
solutions for various storage requirements. These capabilities are achieved by using network
access protocols, such as Network File System (NFS), Common Internet File System (CIFS),
HTTP, FTP, and iSCSI. They are also achieved by using storage area network technologies,
such as Fibre Channel and Fibre Channel over Ethernet (FCoE). The N series features
built-in Redundant Array of Independent Disks (RAID) technology. Further advanced data
protection options include snapshots, backup, mirroring, and replication technologies that can
be customized to meet client’s business requirements. These storage systems also have
simple management interfaces that make installation, administration, and troubleshooting
straightforward.
The N series unified storage solution supports file and block protocols, as shown in
Figure 1-1. Converged networking also is supported for all protocols.
Figure 1-1 Unified storage
This type of flexible storage solution offers the following benefits:
򐂰 Heterogeneous unified storage solution: Unified access for multiprotocol storage
environments.
򐂰 Versatile: A single integrated architecture that is designed to support concurrent block I/O
and file servicing over Ethernet and Fibre Channel SAN infrastructures.
򐂰 Comprehensive software suite that is designed to provide robust system management,
copy services, and virtualization technologies.
򐂰 Ease of changing storage requirements that allow fast, dynamic changes. If more storage
is required, you can expand it quickly and non-disruptively. If existing storage is deployed
incorrectly, you can reallocate available storage from one application to another quickly
and easily.
