4  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 clientâs 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.

This type of flexible storage solution offers the following benefits: 
ň° Heterogeneous unified storage solution: Unified access for multiprotocol storage 
environments.
ň° Versatile: A single integrated architecture that is designed to support concurrent block I/O 
and file servicing over Ethernet and Fibre Channel SAN infrastructures.
ň° Comprehensive software suite that is designed to provide robust system management, 
copy services, and virtualization technologies.
ň° 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.
