The challenge: Manage data to achieve low cost of ownership and high data availability

To successfully meet business goals, effective data management is essential. Optimized data management requires storage solutions with high data availability, strong storage management capabilities and powerful performance features. Your budget requires a low cost of ownership. By implementing scalable and cost effectively storage capacity, you can take advantage of emerging technologies as information demands change. Also, you can go beyond respond and recover in the case of outages with powerful, dynamic backup and recovery capabilities to help you protect data and prevent failure.

The solution: IBM System Storage DS4700 Express

Designed to provide lower 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 112 TB of physical storage capacity with 112 1 TB SATA disk drives.
  
• Powerful system management, data management and data protection features.

The DS4700 Express expands from workgroup to enterprise-wide capability with six attached 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.

Achieve a lower total cost of ownership

Performance capabilities that can reduce the need for additional host ports can help you lower the total cost of ownership with DS4700 Express. Data-intensive applications that demand increased connectivity can benefits from a high-performance 4 Gbps capable Fibre Channel interface. Get the capacity of eight 4 Gbps capable host channels directly attached to host servers or connected to a Fibre Channel storage area network (SAN). To achieve these speeds, four Gbps capable drives and IT infrastructure are required.

There are two ways to measure the performance of a SAN device megabytes per second (MBps), and input/output per second (IOPS). Assuming a 4 Gbps capable system, DS4700 Express provides up to 1550 MBps throughput 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.

On the host side, if a server requires more than the minimum of two 2 Gbps host bus adapters (HBAs) for availability to attain the required performance, then that number can be halved with 4 Gbps. Fewer HBAs help lower the number of switch ports used and can help reduce overall cost.
