Manage data more effectively with IBM System Storage DS5020 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 DS5020 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 DS5020 Express offers:
- High-performance 8 Gbps capable Fibre Channel connections.
- Optional 1 Gbps iSCSI interface.
- Up to 224 TB of physical storage capacity with 112 2 TB SATA 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. 8 Gbps FC allows companies to reduce the number of HBAs per server and the number of overall ports in their FC SAN infrastructure without sacrificing performance, thus saving acquisition and operational costs.
Additionally, the DS5020s 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 inevitably becomes 8 Gbps.
The DS5020s design 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 requirement, and 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/or capacity demandslower acquisition and operational expenditures.
