Manage data effectively
Optimized data management requires storage solutions with high data availability, strong storage management capabilities and powerful performance features. The IBM System Storage® DS5020 Express® is designed to provide low total cost of ownership, high performance, robust functionality and unparalleled ease of use. As part of the System Storage DS5000 series storage system, the DS5020 Express offers:
- High-performance 8 Gbps-capable Fibre Channel connections.
- Optional 1 Gbps iSCSI interface.
- Up to 336 TB of physical storage capacity with 112 SAS-NL (3 TB) disk drives.
- Powerful system management, data management and data protection features.
Achieve a low total cost of ownership
Facing relentless data growth and shrinking budgets, companies continue to look for ways to improve efficiency and reduce costs. Eight Gbps Fibre Channel allows companies to reduce the number of host bus adapters per server and the number of overall ports in their Fibre Channel storage area network (SAN) infrastructure without sacrificing performance, thus saving acquisition and operational costs.
Additionally, auto-negotiating 8 Gbps Fibre Channel interfaces allow the DS5020 Express to integrate seamlessly into an existing 2 Gbps or 4 Gbps infrastructure, while offering investment protection going forward when the SAN inevitably becomes 8 Gbps.
The system is designed to help you avoid over-configuration for an affordable entry-point while offering seamless “pay-as-you-grow” scalability as requirements change. Its efficient storage use is designed to reduce raw capacity requirements. The ability to intermix high-performance and high-capacity drives enables tiered storage in a single enclosure. These unique abilities reduce the number of drives needed to meet performance and capacity demands and can significantly reduce acquisition and operational costs.
