Data
Protection and Access Control on Storage Area Networks
Managing Data Access in Storage Area Networks
Volume Logix provides secure shared or selective access to designated
logical Symmetrix data volumes for authorized users.
First Software to Manage Data Access
Managing the complexity of connecting and accessing hundreds of Windows
NT® or UNIX® servers in an enterprise requires highly specialized
control. Without providing a way to control information access, there
is the potential for servers to gain unauthorized entry to volumes
of sensitive information. And as the enterprise evolves and grows,
storage, servers, and access privileges must often be reallocated.
To date, no storage or Fibre Channel supplier has been able to provide
a solution that can span a heterogeneous environment.
Volume Logix is the first software solution to provide flexible, intuitive,
easy-to-implement data protection and volume access control in a Fibre
Channel-based storage network topology. It allows storage administrators
of Symmetrix-based information to centrally manage and control heterogeneous
volume access in Storage Area Networks (SAN). SAN extends the value
of enterprise storage throughout more of the organization and enables
your information infrastructure to evolve with your enterprise. SAN
simplifies access to the exponential growth of information while Volume
Logix optimizes the information protection of those assets.
Volume Logix provides storage-centric access control of storage volumes,
in both mixed and homogeneous platform environments. When used with
host computers that are connected via a Fibre Channel-Switch Fabric
(FC-SW) or a Fibre Channel-Arbitrated Loop (FC-AL), Volume Logix enhances
information protection through more of the organization. Protection
is provided on the Symmetrix and managed by a Graphical User Interface
(GUI) on a management server that is part of the Storage Area Network.
Best Protection Through Symmetrix Storage-Based
Software
By protecting data at the storage-level, Volume Logix provides centralised
control of data, taking the burden of information protection off departments
while accommodating administrators' ability to freely change host
and operating systems environments. Volume Logix even shields data
from inadvertent access from host servers trying to access protected
volumes. Storage-based Volume Logix software eliminates high management
and overhead costs associated with volume access and control. With
Volume Logix, administrators manage data access once, at the storage-level
instead of at every server in the environment.
Volume Access Control for Mixed Environments
Volume Logix allows multiple UNIX and NT server hosts to share the
same Symmetrix Fibre Adapter port while providing multiple volume
access controls and data protection. The Volume Logix software also
provides volume access management for non-supported Volume Logix GUI
and Host Utilities platforms that are connected via Fibre Channel
(e.g. Siemens, Sequent, IBM AIX).
No Agent Software on Servers
With Volume Logix, the software intelligence resides on Symmetrix
and includes a database that tracks and controls host volume access.
This design feature eliminates the necessity for device polling and
host-based I/O filtering, imposing no impact on server CPU cycles.
Host servers can run Volume Logix host utilities to simplify and expedite
volume access configurations with the Symmetrix.
Volume Logix Protects Data in Storage
Area Networks
Volume Logix manages the way servers use centralised consolidated
storage on a Storage Area Network. With Volume Logix, storage administrators
can efficiently allocate Symmetrix storage among host servers located
on a Fibre Channel switch or hub, ensuring the integrity of the data.
Together, Volume Logix and Symmetrix provide the robust data protection
needed to effectively implement an enterprise-wide storage solution.
Today, organizations can take advantage of the additional connectivity,
bandwidth, and extended distance capability offered by SANs to connect
isolated servers to storage throughout the enterprise. This creates
an organizational environment where information is centralised and
efficiently managed, protected, and available for sharing. Servers
are deployed (and redeployed) at the department level, where they
are most needed and accessible.
Improves performance through easy-to-read, easy-to-use display windows.
Easy-to-Use
Volume Logix features an intuitive graphical user interface (GUI)
for Microsoft Windows NT, HP-UX, and Sun Solaris platforms. This ease
of use feature streamlines system administrator's volume access configuration
tasks while providing a complete, easy to understand graphical topology
of the Symmetrix volume assignments to the host computers. The GUI
also contains a task list manager to flexibly stage configuration
changes. Additionally, a Command Line Interface (CLI) is also supported
and suitable for scripts that can easily automate procedures. Both
GUI and CLI interfaces provide the best choice selection for the types
of tasks to be performed when configuring volume access.
