and up to 64 storage partitions. The
DS4300 dual controller and DS4300
Turbo offer up to 28TB of Serial ATA
physical disk storage capacity with the
DS4000 EXP100.
Other features of the turbo option
include an increased cache size of 2GB
and an auto-sensing capability to help
detect host connectivity speed. This
auto-sensing capability adds support
for 1Gbps Fibre Channel connectivity to
the base model’s 2Gbps Fibre Channel
interface, allowing the DS4300 to sup-
port a wider range of devices and thus
is designed to provide greater interop-
erability. The turbo option also helps
extend the copy services capabilities
of the DS4300 by including the
VolumeCopy feature, which is designed
to enable full replication of logical
volumes for enhanced data manage-
ment and protection. Also available is
version 9.1 with turbo option supporting
Enhanced Remote Mirroring for replica-
tion of logical volumes.
Centralized administration through DS4000
Storage Manager
The TotalStorage DS4000 Storage
Manager software included with the
DS4300 is designed to support central-
ized management of all local and net-
worked DS4000 series systems.
DS4000 Storage Manager allows
administrators to quickly configure and
monitor storage from a Java™-based
Web browser interface. 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.
The turbo option includes DS4000
Storage Manager version 8.4, which is
designed to support up to 256 logical
volumes per storage partition, array
groups up to 2TB and the SCSI-3
Persistent Reservation facility for
enhanced server clustering applica-
tions. These additional capabilities help
the DS4300 to support larger storage
environments.
