Access "Bridging the gap"

Published: 19 Oct 2012

High-speed optical WANs are becoming indispensable for critical storage applications. Business continuance, remote mirroring and replication, and connecting regional data centers are all tasks that require optical WANs. With many optical options and prices, picking the best technologies and techniques to transport data is challenging. Most storage apps are time-sensitive and require high throughput (bandwidth) and low latency with zero data loss. Effective bandwidth is a measure of how much of the available bandwidth can actually be used, taking into consideration dropped packets and retransmission due to congestion and protocol inefficiency. Some vendors, including Ciena Corp., Linthicum, MD, refer to effective bandwidth as "good put" vs. simply looking at a theoretical line speed number. To pick a data transport to fit your needs, first consider your storage requirements: Distance. How far away do you need to keep a copy of your data? Bandwidth. How much data must be moved and in what timeframe? Cost. What's your budget? Recovery point objective. Can you ... Access >>>

    • Archiving unstructured data by Jerome Wendt

      Companies must find ways to automate and simplify the process of archiving files and e-mail messages. ECM software addresses this large pool of unstructured data.

    • Bridging the gap

      Many disaster recovery and remote backup programs rely on an efficient, cost-effective WAN. Fiber-optic network technology is often required for long-distance data transmission, but you need to know what transport is best and the related implementation issues.

    • New tools to classify data by Brad O'Neill

      Putting data on storage systems appropriate to its value requires the ability to classify data. An emerging category of applications, Information Classification and Management apps, can index enterprise information and execute precise actions based on its content.
