The challenge: Managing data to achieve a low cost of ownership and high data availability
Effective data management is essential to the success of your enterprise if business goals are to be met. You need a storage solution that has a low cost of ownership while providing high data availability, strong storage management capabilities, and powerful performance features. You need to be able to easily and cost effectively scale storage capacity and take advantage of emerging technologies as information demands change. Powerful, dynamic backup and recovery capabilities can help you protect data and prevent failure—not just respond and recover.
The solution: IBM System Storage DS4700 Express
In a continuing effort to provide storage solutions that are designed to provide low total cost of ownership, high performance, robust functionality, and unparalleled ease of use, IBM offers the IBM System Storage DS4700 Express. As part of the DS4000 series, the DS4700 Express offers high-performance 4 Gbps capable Fibre Channel connections, up to 84 TB of physical storage capacity with 112 750 GB SATA disk drives, and powerful system management, data management and data protection features. The DS4700 Express is designed to expand from workgroup to enterprise-wide capability with the attachment of six DS4000 EXP810 disk enclosures. The DS4700 Express DC Models are NEBS-3 compliant storage systems designed to be powered from a -48 Volt DC Telco industry-standard power source. The DS4700 Express is available in a 3U high enclosure and mounts in a 19-inch rack-mount package.
Helping to achieve a low Total Cost of Ownership (TCO)
The IBM System Storage DS4700 Express Model supports a high-performance 4 Gbps capable Fibre Channel interface designed for data-intensive applications that demand increased connectivity. The DS4700 Express supports eight 4 Gbps capable host channels that may be directly attached to host servers or connected to a Fibre Channel storage area network (SAN). Four Gbps capable drives and IT infrastructure are required to achieve 4 Gbps capable throughput speeds.
There are two ways to measure the performance of an SAN device: Megabytes per second (MBps) and input/output per second (IOPS). The DS4700 Express 4 Gbps SAN solution is designed to provide up to 1550 MBps throughput (assuming a 4 Gbps capable system) with up to 121,500 IOPS. A 2 Gbps storage array can require up to twice as many host ports as a 4 Gbps array to deliver the throughput of four 4 Gbps ports. The DS4700 Express can help you free up or eliminate the need for additional host ports in the SAN for each array.
