Other DS3950 Express features that can help enhance data
management and protection include:
FlashCopy, which enables point-in-time copies of logical
volumes that may be used for file restoration, backups,
application testing or data mining
Dynamic volume expansion, which allows administrators
to resize logical volumes without disrupting users
VolumeCopy, which provides full replication of one logical
volume (source) to another (target) within DS3950
Enhanced Remote Mirror, which consists of Global Mirror
with Asynchronous Write-order Consistency (a critical fea-
ture for mirroring multi-logical unit number [LUN] applica-
tions), Global Copy with Asynchronous and Metro Mirror
with Synchronous capabilities
DS3950 Express uses 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
DS3950 is supported by a variety of IBM Tivoli® software
products. IBM Tivoli Storage Manager, IBM Tivoli Storage
Resource Manager and many third-party hardware and software
products can add to the capabilities of DS3950 by enabling
backup and storage reporting.
Service, support, and financing
DS3950 Express comes with a three-year, 9x5, next-business-
day hardware and software warranty. Additional services for
hardware installation, DS Storage Manager configuration
and advanced storage management are also available from
IBM Global Services. IBM Support Line services can assist
you with using DS Storage Manager to enable self-
maintenance for the DS3950 system.
The optional IBM Remote Support Manager for Storage
enables DS3950 to quickly notify the IBM Support Center
when the system detects a problem. This notification can
help reduce or eliminate the need for a service call. To help
expedite diagnosis and repair of failed hardware and software,
error alert messages from DS Storage Manager can be
forwarded through email.
