SCSI reliability, with scalability for
tomorrow
By utilizing standard xSeries hot-swap
Ultra320 SCSI drives which are
designed to offer high mean-time-
between-failure, the DS300 is ideal for
high I/O processor (IOP) performance
today—and allows for future growth
tomorrow. The modular design of the
DS300 is designed to allow you to eas-
ily perform upgrades and additions to
help meet the needs of your growing,
changing application environment—
scaling to support increasing volumes
of data flexibly and affordably.
In addition, advanced software features
on the DS300—including access con-
trol lists (ACLs), online array expansion,
online LUN expansion and Global
HotSpare—are designed to give admin-
istrators the power to configure storage
according to changing usage needs.
These features also help enable IT man-
agers to share storage across multiple
application servers.
Designed to ensure business continuity
At entry-level prices, the DS300 is
designed with impressive redundancy
features. The subsystem is a rack-
mountable, 3U enclosure with 14 SCSI
drives and redundant design, hot-swap
power and cooling modules, the DS300
features RAID reliability and high-
availability software to help maintain
operations.
The storage subsystem supports
either one or two controllers for high-
availability configurations. Each con-
troller is designed to support two
Gigabit Ethernet ports for data paths
and one port for management so that—
even if a line or a controller fails—
multiple paths between servers and
storage can help maintain a
connection.
The DS300 also offers optional
advanced features such as
IBM FlashCopy® solutions, which are
designed to help reduce storage
backup windows and improve
storage utilization for Microsoft®
Exchange, Microsoft SQL Server™
2000 and Lotus Notes® applications.
Powerful management tools
The DS300 is designed to offer
excellent storage management and
configuration capabilities through
IBM ServeRAID Manager, helping
enable clients to manage multiple
IBM TotalStorage DS300 and
DS400 subsystems—as well as direct-
attached internal ServeRAID
controllers—all through a single, easy-
to-use management console with
an extensive online help library.
Configuration wizards simplify initial
storage setup. IBM ServeRAID Manager
is designed to support most common
operating environments for workgroup
applications.
The management software of the
DS300 is built directly into the
client/server workgroup manager
IBM Director. IBM Director is designed
to allow IT administrators to view and
track the hardware configuration of
remote systems in detail and monitor
the usage and performance of critical
components, such as processors,
disks and memory.
