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 DS5020’s 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 DS5020’s 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 demands—lower acquisition and operational expenditures.
|
Host interface intermix |
- Support for intermixing FC and iSCSI
interfaces allows for cost-effective SAN tiering
|
|
Balanced performance |
- Equally adept at IOPS and MB/s, the
DS5020 is able to support applications with wide-ranging performance
requirements.
- Well suited for data warehousing,
consolidation and virtualization environments that have diverse workloads
and application requirements
- Designed to concurrently support
transactional-applications, such as databases and OLTP, and
throughput-intensive applications, such as HPC and rich media.
|
|
Support for self-encrypting drives |
- Comprehensive protection for
data-at-rest ensures data is secured throughout the drive’s lifecycle
without sacrificing storage system performance or ease of use
|
|
Up to 112 intermixed drives |
- Ability to intermix FC, FDE, SSD and
SATA disk drives enables tiered storage
- FC disk is allocated to applications
that demand high performance and have high I/O rates and less-expensive
SATA disks are allocated to applications that require less performance
- Enclosure-based intermixing maximizes
efficiency
|
|
Built-in efficiencies |
- Modular design avoids over-configuration
for an affordable entry-point while offering seamless “pay-as-you-grow”
scalability as requirements change.
- Efficient utilization lowers raw
capacity requirement, and support for intermixing high performance and
high capacity drives enables tiered storage.
- Exceptional per drive performance
creates performance value by getting the most performance out of the
fewest drives.
