Multiple DS4300 Express models can
use a common pool of hot-spare disk
drives as a cost-effective way of
improving availability, even if the
DS4300 Express models are attached
to different servers. IT administrators
can determine the number of drives to
allocate as spares.
Additional tools to help manage storage
The DS4300 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 many
other third-party hardware and software
products. These applications can add
to the capabilities of the DS4300
Express by enabling backup and stor-
age reporting.
The IBM TotalStorage Proven™ pro-
gram is designed to identify and test
many of these products for interoper-
ability with the DS4300 Express and
other IBM disk products. Products in
this program have been tested to help
reduce or eliminate time-consuming
installation and support issues. For
