DS4000 Intermix feature for attaching
Fibre Channel and Serial ATA Disk Storage
Expansion units
The IBM System Storage DS4800 mid-
range disk system has the capability to
support attachment of both DS4000
EXP810/EXP710 Fibre Channel Disk
Expansion units and DS4000 EXP100
Serial ATA Disk Expansion units concur-
rently and also supports attachment of
both DS4000 EXP810 and DS4000
EXP710 Fibre Channel Disk Expansion
units concurrently. This feature is
designed to allow you to create and
manage distinct array groups that are
built from either FC or SATA disks and
allocate logical drives to the appropriate
applications utilizing a single DS4000
system. Those applications that
demand high performance and have
high I/O rates could use the FC-based
drives, while near-line or applications
that do not demand the higher perform-
ance can be maintained on the SATA
based-drives.
Centralized administration through DS4000
Storage Manager
The TotalStorage DS4000 Storage
Manager software included with the
DS4800 is designed to support central-
ized management of all local and
networked DS4000 series systems.
DS4000 Storage Manager allows
administrators to quickly configure
and monitor storage from a Java™
technology-based GUI. It is also
designed to allow them to customize
and change settings as well as config-
ure new volumes, define mappings,
handle routine maintenance and
dynamically add new enclosures and
capacity to existing volumes—without
interrupting user access to data.
Failover drivers, performance-tuning
routines and cluster support are also
standard features of the DS4000
Storage Manager.
By providing these features and an intu-
itive user interface, the DS4000 Storage
Manager is designed to help reduce the
complexity of storage management and
the amount of time spent managing
storage.
Enhanced storage management
capabilities
The IBM System Storage DS4800 has
several features designed to improve
data management and storage system
performance. Using the DS4000
Storage Manager software, administra-
tors can partition the DS4800 into as
many as 64 virtual servers. This capa-
bility allows IT organizations to strategi-
cally allocate storage capacity, helping
to optimize the utilization of storage
space and helping reduce hardware
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 DS4800—which is
designed to provide hardware failover
with dual controllers and common
management.
Other DS4800 features that can help
enhance data management and
protection include FlashCopy, Dynamic
Volume Expansion, VolumeCopy and
Enhanced Remote Mirroring.
The FlashCopy feature is designed to
take point-in-time copies of logical
volumes, which may be used for file
restoration, backups, application testing
or data mining.
Dynamic Volume Expansion is designed
to allow administrators to resize logical
volumes without disrupting users. This
feature can work well for applications
with rapidly growing data requirements,
such as IBM Lotus Notes® and
Microsoft® Exchange.
