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 SoftwareBy 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.
