and Windows 2000 Advance Server
operating system and optional support
for AIX® (except single controller), Sun
Solaris, HP-UX, Novell NetWare and
Linux® operating systems. The
DS4300 Express is designed to interop-
erate with IBM _`® pSeries®
and xSeries® servers as well as with
Intel® processor-based and UNIX®
operating system-based servers. To
help make integration easy, IBM tests
the DS4300 Express for interoperability
with IBM servers, as well as with many
other brands of servers and switches.
Part of the DS4000 series
The DS4300 Express is part of the
DS4000 series, which uses common
storage management software and
expansion enclosures. Dual controller
models are designed to be compatible
with existing DS4000 EXP710 Express
disk enclosures and include many of
the same high-performance software
and redundant hardware design fea-
tures as other DS4000 series systems.
The DS4300 Express dual controller
models can also be used with the
DS4000 EXP100 Express Serial ATA
disk drive storage unit. This helps
address the requirements of various
fixed content and data reference appli-
cations which require large amounts of
storage capacity but do not have the
high utilization and access characteris-
tics satisfied by DS4000 EXP710
Express Fibre Channel disk drive
storage.
Scalability throughout the series
Because the DS4300 Express is highly
scalable, up to 112 fibre channel with
turbo option or 112 Serial ATA disk
drives, it can be upgraded from a work-
group SAN to an enterprise network
storage system, thereby providing flexi-
bility to grow with your business. In
addition, by using the IBM TotalStorage
DS4000 Storage Manager software,
multiple DS4300 Express models can
be combined to help address
additional performance and capacity
requirements—further enhancing your
scalability options.
Another scalability feature of the
DS4300 Express is Dynamic Capacity
Expansion (DCE), which is designed to
provide the ability to add DS4000
EXP710 Express or DS4000 EXP100
Express enclosures to an existing
DS4300 Express dual controller model
or DS4000 EXP710 Express, or
EXP100 Express to a DS4300 Express
with Turbo feature without stopping
operations. By adding these enclo-
sures, the DS4300 Express can help
bring unused storage online for a new
host group or an existing volume to
provide additional capacity on demand.
It is designed to allow upgrades to
higher performing DS4000 series sys-
tems while keeping data intact, helping
to minimize disruptions during
upgrades. The DS4300 Express also
supports online controller firmware
upgrades, to help provide better per-
formance and functionality. Events such
as upgrades to support the latest ver-
sion of DS4000 Storage Manager or to
add services such as DS4000 Service
Alert, or the new DS4000 Alert
Manager, can generally be executed
without stopping operations.
