Datasheet

Dynamic Volume Expansion is designed
to allow administrators to resize logical
volumes while avoiding disruption to
users. This feature can work well for
applications with rapidly growing data
requirements, such as Lotus Notes®
and Microsoft® Exchange.
The VolumeCopy feature is designed to
provide full replication of one logical vol-
ume (source) to another (target) within
the DS4700 Express. VolumeCopy fea-
tures support read-only access to the
source volume during the copy process
and suspend writes to support point-
in-time integrity.
Enhanced Remote Mirror consists of
Global Mirror with Asynchronous
Write-order Consistency. This is critical
for mirroring multi-LUN applications,
Global Copy with Asynchronous, and
Metro Mirror with Synchronous.
The DS4700 Express is designed to
use a common pool of hot-spare disk
drives as a cost-effective way to help
improve availability. IT administrators
can determine the number of drives to
allocate as spares.
Additional tools to help manage storage
The DS4700 Express is supported by a
variety of IBM Tivoli® software prod-
ucts, including IBM Tivoli Storage
Manager and IBM Tivoli Storage
Resource Manager, as well as other
third-party hardware and software prod-
ucts. These applications can add to the
capabilities of the DS4700 Express by
enabling backup and storage reporting.
The IBM System Storage Proven™ pro-
gram is designed to identify and test
many of these products for interoper-
ability with the DS4700 Express and
other IBM disk products. Products in
this program have been tested to help
avoid time-consuming installation and
support issues. For more information,
please visit ibm.com/storage/proven.
Service and support
The DS4700 Express has a three-year
hardware warranty with a 9x5 next
business day response time that is
upgradeable to a 24x7 4-hour response
time. Additional services for hardware
installation, DS4000 Storage Manager
configuration, and advanced storage
management are available from
IBM Global Services. IBM Support Line
services can assist with using DS4000
Storage Manager, helping you to self-
maintain your DS4000 system.
The optional DS4000 Service Alert and
the DS4000 Alert Manager services are
designed to enable the DS4700
Express to quickly notify the
IBM Support Center when the system
detects a problem, helping to avoid the
need for you to place a service call.
This feature is capable of forwarding
error alert messages (via e-mail) from
the DS4000 Storage Manager to
IBM to help expedite diagnosis and
repair of failed hardware and software
problems.
