Enhanced storage management
capabilities
The IBM TotalStorage DS4300 has sev-
eral features designed to improve data
management and storage system per-
formance. Using the DS4000 Storage
Manager software, administrators can
partition the DS4300 into as many as
16 virtual servers; with the turbo option,
they can create up to 64 partitions. This
capability allows IT organizations to
strategically allocate storage capacity,
helping to optimize the utilization of
storage space and help reduce hard-
ware and storage management costs.
Instead of purchasing multiple RAID
controllers with their own dedicated
disks and management, organizations
can attach multiple servers to one cen-
tral system—the DS4300—which is
designed to provide hardware failover
with dual controllers and common
management.
Other DS4300 features that can help
enhance data management and protec-
tion include FlashCopy®, Dynamic
Volume Expansion, VolumeCopy and
Enhanced Remote Mirroring.
●
The IBM FlashCopy feature is
designed to take instant point-
in-time copies of logical volumes,
which may be used for file restora-
tion, backups, application testing or
data mining
●
Dynamic Volume Expansion is
designed to allow administrators to
resize logical volumes without dis-
rupting users. This feature can work
well for applications with rapidly
growing data requirements, such as
Lotus Notes® and Microsoft
Exchange
●
Available only with the turbo
option, the VolumeCopy feature is
designed to provide full replication
of one logical volume (source) to
another (target) within the
DS4300. VolumeCopy is designed to
allow read-only access to the source
volume during the copy process,
and suspend writes to support
point-in-time integrity
●
Supported with V9.1 is Enhanced
Remote Mirror. It consists of Global
Mirror with Asynchronous Write-
order Consistency, which is critical
for mirroring multi-LUN applica-
tions, Global Copy with
Asynchronous and Metro Mirror
with Synchronous
Multiple DS4300s can use a common
pool of hot-spare disk drives as a cost-
effective way of improving availability,
even if the DS4300s are attached to
different servers. IT administrators can
determine the number of drives to allo-
cate as spares.
Additional tools to help manage storage
The DS4300 is supported by a variety
of IBM Tivoli® software products,
including IBM Tivoli Storage Manager
and IBM Tivoli Storage Resource
Manager, as well as many other third-
party hardware and software products.
These applications can add to the
capabilities of the DS4300 by enabling
backup and storage reporting.
The IBM TotalStorage Proven™ pro-
gram is designed to identify and test
many of these products for interoper-
ability with the DS4300 and other
IBM disk products. Products in this pro-
gram have been tested to help reduce
or eliminate time-consuming installation
and support issues. For more
