Overview of the Lightning 9900™ Subsystem
1.1.5 Hitachi Freedom NAS™ and Hitachi Freedom SAN™
Hitachi Freedom Data Networks™ (FDN) provide an open architecture that offers
organizations freedom of choice in deploying data access, protection, and sharing
capabilities across the enterprise. Using multiple technologies and solutions such as storage-
area networks (SANs) and network-attached storage (NAS), FDN builds, leverages, and
augments storage infrastructures, providing access to any data from any computer, anytime
and anywhere.
Hitachi Freedom NAS™ and Hitachi Freedom SAN™ solutions are the core offerings behind the
FDN approach. They complement the Hitachi Freedom Storage™ subsystems by allowing
more flexibility than ever in heterogeneous environments. While SAN architectures respond
to high bandwidth needs, NAS addresses the need for rapid file access, especially critical for
e-business applications. Hitachi Data Systems offers the best of both.
FDN encompasses storage, switches and hubs, servers/clients, management software,
protocols, services, and networks developed by Hitachi, our alliance partners, and third
party providers. FDN facilitates consolidation of server and storage resources, data sharing
among heterogeneous hosts, centralized resource and data management, superior data
security, and increased connectivity.
Hitachi Freedom SAN™. Hitachi Data Systems’ SAN solutions give you the freedom to locate
storage wherever needed and protect your investment in currently installed components.
Made possible by the advent and proliferation of high-speed fibre-channel technology, SANs
break the traditional server/storage bond and enable total connectivity. As a result, you can
add, remove, or reassign any resource without interfering with ongoing business operations.
The Lightning 9900™ subsystem features unparalleled reliability, a SAN-ready architecture,
and support for S/390

platforms. Hitachi adds software and
services to SAN components to provide functionality such as LAN-free backup, remote copy,
and multiplatform data exchange from our Freedom Storage™ software suites.
