Applications |
Application
development
The entry-level price and flexible management tools of
the D220 disk system reduce the cost and effort of
application development projects. Common management
tools with other D-Series disk systems makes the
transition to production easier and more reliable.
|
Storage
consolidation
The D220 disk system can be used to consolidate storage
for small groups of users or applications. With
SANtricity™ Storage Manager software, management and
configuration tasks are centralized with an easy-to-use
interface. |
Workgroup and
departmental computing
When implemented behind one or several servers, the D220
can affordably meet the multi-purpose storage needs of
workgroups and departments. Future departmental
expansion is eased with upgrades to larger D-Series disk
systems. |
|
|
|
Benefits |
Increased
customer satisfaction
The D220 system’s high-speed disk performance increases
application responsiveness and processing times. This
helps you improve customer satisfaction and free up
valuable staff resources. |
Simplified
management
Use SANtricity™ software to manage your storage as a
single system. Add capacity, set up storage and
configure changes with ease. |
Investment
protection
The D220 system offers a non-disruptive growth path and
common software that is transferable to higher-end
StorageTek D-Series solutions. You can dynamically
adjust capacity, software and hardware. |
Cost savings
With its excellent performance-to-cost ratio, the D220
subsystem helps you cut storage costs for workgroups and
departments. Simplified management reduces
administration time and expenses. |
|
|
|
Features |
Remote Volume
Mirroring
Available cross-mirroring capabilities enable two
separate systems to function as remote disaster recovery
sites for each other, to help ensure business
continuity. |
Modular
architecture
As your business grows, you can transfer data and
features to higher performance StorageTek systems
without disruption, protecting both your information and
your investments. |
Two gigabit
Fibre Channel connectivity
The D220 provides a full, end-to-end two-gigabit Fibre
Channel storage solution that is supported in all major
Windows and UNIX environments. |
