Manage data more effectively with IBM System Storage DS3950 Express
Optimized data management requires storage solutions with high data availability, strong storage management capabilities and powerful performance features. IBM offers the IBM System Storage® DS3950 Express®, designed to provide lower total cost of ownership, high performance, robust functionality, and unparalleled ease of use. As part of the IBM DS series, the DS3950 Express offers:
- High-performance 8 Gbps capable Fibre Channel connections
- Model 98H offers 1 Gbps iSCSI interface
- Up to 224 TB of raw physical capacity using 112 SATA 3.5-inch drives (2 TB) disk drives
- Powerful system management, data management, and data protection features
Achieve a lower total cost of ownership
Facing relentless data growth and shrinking budgets, companies continue to look for ways to reduce costs through efficiencies. The advent of 8 Gbps Fibre Channel allows companies to reduce the number of host bus adapters (HBAs) per server and the number of overall ports in their Fibre Channel SAN infrastructure without sacrificing performance, thus saving on both acquisition and operational costs.
Additionally, the DS3950 auto-negotiating 8 Gbps Fibre Channel interfaces allow it to seamlessly integrate into an existing 2 Gbps or 4 Gbps infrastructure, while providing the buyer with investment protection going forward when the SAN standard increases to 8 Gbps.
The design of the DS3950 avoids over-configuration for an affordable entry-point while offering seamless pay-as-you-grow scalability as requirements change. Its efficient storage utilization lowers raw capacity requirements, and its support for intermixing high performance and high capacity drives enables enclosure-based tiered storage. These unique capabilities reduce the number of drives needed to meet performance and capacity demands; that means lower acquisition and operational expenditures.
