The Payment Card Industry Data Security Standard (PCI DSS) is a set of industry regulations imposed by the major credit card companies to ensure the safety, security, and integrity of cardholder data. Any business that processes, stores, and transmits cardholder account data must comply with this complex new standard, and must be able to demonstrate that compliance through automated and manual audits of their systems. This white paper looks at the key challenges and requirements of PCI DSS as it relates to Microsoft Windows and Active Directory, and shows you how a third-party software solution can help with PCI compliance.

There are many compelling reasons for virtualizing Windows and Linux applications. Virtualization improves server utilization by allowing you to run multiple workloads on a single physical server. It reduces the number of physical servers you have to maintain, while allowing you to use less physical space and power while still improving scalability. All of these capabilities translate directly into lower costs, less complexity, and greater flexibility in your mixed IT environment.

The powerful tape technology can address data security with tape encryption as well as long term data protection.
Discover what disk and tape really cost -- and which solution provides lower total cost of ownership and optimizes energy use for your organization
The Clipper Group explores the truth behind the myths of tape, digging into the misconceptions in the disk vs. tape debate.
Over two thirds of disk-only users look to add tape back into storage infrastructure according to recent survey.
Since the emergence of Fibre Channel SANs in the late 1990s, enterprise IT managers have maintained two sets of networks, one for storage I/O traffic and the other for data network traffic. But system consolidation and SAN expansion efforts are driving the need for a unified fabric where multiple traffic types -- network, storage and clustering -- are all carried over a single network infrastructure.
Several options to unify and extend the reach of storage networks have emerged over the last decade, including iSCSI, FCIP, iFCP and InfiniBand. But these options turned out to be performance intensive, too disruptive or, in the case of InfiniBand, required the introduction of new infrastructure.
To facilitate convergence and overcome the problems encountered with the other attempts, a consortium of storage and data network vendors under the aegis of the INCITS T11 committee is working on a new standard called Fibre Channel over Ethernet (FCoE). FCoE is designed to enable network convergence and cost-effective SAN expansion in the enterprise data center.
The basic concept is to use 10G Ethernet to carry native Fibre Channel traffic alongside standard network traffic. However, Ethernet does not provide the performance and reliability characteristics required for carrying Fibre Channel traffic, so several enhacements are required.
Enhancements to Ethernet
The key drawbacks of Ethernet are that it is prone to high latencies and packet loss when the network gets congested – characteristics that are highly unsuitable for storage traffic. The IEEE is working on enhancements to the Ethernet protocol -- appropriately called Enhanced Ethernet -- that would enable the venerable technology to support multiple traffic types.
Key enhancements to 10G Ethernet include the ability to:
* Control the flow of traffic -- without packet loss -- at a more granular level through the implementation of priority flow control.
* Allocate bandwidth dynamically and ensure QoS for multiple classes of traffic.
