Merging Backup and Disaster Recovery (DR) Processes
For years, disaster recovery (DR) and data protection practices have consisted of two different technology islands — data protection and tape backup. The processes to implement both have usually been separate and handled by different IT departments. Enterprises have attempted to merge the two, but many still use different software products and different processes for replication and tape backup. This paper describes how continuous data protection (CDP) technology can bridge various DR methodologies to help organizations overcome the challenges of tape and achieve maximum benefits from their IT investments.

Wide Area Data Services: Optimizing the Branch
In February 2004, Taneja Group defined the term Wide Area File Services (WAFS) to describe a group of bright young companies that were optimizing network file access across wide geographic areas. Since that term, we have continued to track the rapid evolution of various optimization challenges for the distributed enterprise, spending significant time talking with both customers and vendors. We reached the conclusion that WAFS must now be considered a subset of an even more encompassing category that we define here as Wide Area Data Services (WDS). The pioneering and defining firm in the WDS category is Riverbed Technology, based in San Francisco.

Re-architecting Disaster Recovery Solutions Leveraging WAN Optimization Technology
Disaster Recovery (DR) is not new—many organizations have employed some form of DR for quite some time. Companies have been replicating their mainframe, storage, and database systems for years. Before that, they moved paper documents to offsite locations. So, what‘s new with DR? As business technology proliferated over the past 10 to 15 years, DR coverage expanded from back office systems to all types of additional business applications. New business applications and IT services help organizations react quickly to a dynamic marketplace and provide access to information—wherever and whenever it’s needed. This trend is actually accelerating as:

The Case for a Unified Network Fabric
Historically, technology innovation began in the enterprise, where the IT organization would evaluate and slowly integrate it into corporate business processes. A subset of that technology would then make its way to consumers. Today, the cycle has largely reversed (Figure 1). Now technology innovation increasingly tends to occur in the home first, then makes its way into the enterprise via the employees, not the IT organization.

Managing Data Center Power and Cooling
As server microprocessors become more powerful in accordance with Moore’s Law, they also consume more power and generate more heat. Similar geometric improvement in disk storage technology has driven rapid growth of on line data, using mass storage systems that often consume as much power as the servers themselves. With the rapid growth in computing power and storage capacity, typical data center power consumption (kWh) and power density (kWh/sq. ft.) are both spiraling upward, placing a strain on many existing data center power distribution and cooling systems.

Hot-Lock™ Access Control List (ACL) Technology Intrusion Prevention without Security Holes
Comprehensive network security often requires system administrators to update Access Control List (ACL) entries of a switch/router frequently to prevent newly discovered or pending attacks from affecting the network or networking equipment. Traditionally, because of the manner in which competing network vendors design their switch/router operating software, updating an ACL involves a two-step procedure. This can temporarily create security holes that leave the network vulnerable to attack when applying new or modified ACL to an interface.

Evolution of the Spanning Tree Protocol
The Spanning Tree Protocol that is the basis for the IEEE standard 802.1D was designed to provide ""plug-and-play"" operation for large Layer 2 networks based on half duplex shared Ethernet, which was the prevalent LAN technology throughout the late 1980s and early 1990s. As Ethernet evolved to become a switched full duplex technology, it soon became evident that 802.1D needed to be upgraded in order to keep pace with the new design models and switch features (e.g., VLANs) that emerged to allow optimization of switched networks.

Why Moving to Disk-Based Backup Makes Good Business Sense
For years, organizations have relied on tape as the primary method of backing up critical data. However, managing tape and restoring data from it can be extremely cumbersome, unreliable, time consuming and even costly. Since the cost of disk has fallen, many organizations are turning to disk for faster and more reliable backups and restores. Affordable disk-based backup products are arriving on the market at a time when data is rapidly and continuously growing, offering organizations of all sizes the opportunity to take advantage of a more cost-effective technology that helps to streamline IT operations.

Major Considerations in Moving to Disk-based Backups
Throughout the past 50 years of computing, magnetic tape has been the standard technology for protecting primary disk storage data. Traditionally, IT managers perform weekend full backups and daily incremental backups to recover from lost or corrupted data on their primary storage backup systems. Tapes of these backups are then sent to offsite storage facilities where they become an integral component of the site disaster recovery process.
