Additionally, the DS3950 auto-negotiating 8 Gbps Fibre
Channel interfaces allow for seamless integration into an
existing 2 Gbps or 4 Gbps infrastructure, while providing
organizations with investment protection going forward when
the SAN standard increases to 8 Gbps.
The design of DS3950 avoids over-configuration for an
affordable, entry-point price, while also 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—resulting in lower
acquisition and operational expenditures.
Establish high data availability
Now you can develop storage environments that can deliver
unprecedented data availability using DS3950 Express. Offering
a choice of multiple RAID levels and redundant hot-swappable
components, the disk storage system can help you maintain data
availability and security.
Your data center can also enhance resiliency with IBM disk
storage systems. Powerful dynamic capabilities go beyond tradi-
tional backup and recovery methods to help protect data and
prevent failures. In addition, you gain the benefits of enterprise-
class disaster-recovery strategies and point-in-time copying with
IBM FlashCopy® solutions.
The IBM System Storage DS series allows flexible access to
data that can enhance information insights. The series also
provides a broader range of scale and performance options to
provide structure and context to information. As a result, you
can build data management strategies that align with your
information requirements. DS3950 can help accommodate the
changing value of data over time while maintaining data
availability.
The DS3950 storage system offers redundant components,
automated I/O path failover, and extensive online configuration,
reconfiguration and maintenance capabilities to help ensure
your data is available 24x7. DS3950 is designed to protect
stored data as well. DACstore technology stores configuration
metadata on each drive; Proactive Drive Health Monitoring
(PDHM) technology identifies faulty drives before they create
problems; RAID 6 technology helps guard against concurrent
drive failures and errors; and persistent cache backup is
designed to ensure any data in cache is captured and safe in the
event of a power outage. All of these features combine to create
a system you can trust with your data.
