Designed for enterprise
Open Systems online storage environments, the
two-gigabit Fibre Channel D178 disk subsystem scales to
support more than 32 terabytes of data. With speeds up
to 390 megabytes per second, the D178 subsystem gives
you the throughput you need to meet the demands of
transaction-intensive applications. |

Applications |
Disk
mirroring
With Remote Volume Mirroring, the D178 disk system
has complete synchronous and asyncronous disk
mirroring functionality. It can be used as a local
mirror for sharing or distributing data, or as a
remote mirror for rapid disaster recovery. |
Storage
consolidation
The D178 disk system has the capacity and management
to consolidate storage for multiple business
applications or groups of users. With SANtricity™
Storage Manager software, management and
configuration tasks are centralized with an
easy-to-use interface. |
Online
transaction processing
The D178 disk system has the I/O performance to
enable better response times for demanding
applications such as online transaction processing.
Application growth is less disruptive with upgrades
to larger D-Series disk systems. |
|
|
|
|
Benefits |
Improved
customer service
The D178 system’s full two gigabit per second
architecture delivers exceptional I/O performance to
enable better response times for demanding
applications, such as databases, Exchange and OLTP. |
Higher
availability
The D178 system helps you increase the availability
of business applications through online
administration, redundant components and dual I/O
paths with transparent failover. |
Centralized management
The SANtricity™ software suite provides single-view,
non-disruptive, storage management from your IT shop
floor or from remote locations. |
Investment protection
The D178 system’s modular pay-as-you-go scalability
enables you to buy what you need today and expand as
your storage needs grow—all the way up to 32.7
terabytes. |
|
|
|
|
Features |
SAN readiness
Fabric login support and multi-host heterogeneous
support combine to help you realize the full
potential of storage area networks. |
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. |
Two gigabit
Fibre Channel connectivity
The D178 provides a full, end-to-end two gigabit
Fibre Channel storage solution that is supported in
all major Windows and UNIX environments. |
Secure resource
sharing
The D-Series software suite enables you to share
your D178 disk subsystem as a SAN resource while
ensuring secure, dedicated online storage. |
