Former President Nixon would have balked at Enkive, a new open-source e-mail archiving and retrieval application from The Linux Box. That's because Enkive captures e-mail messages as they arrive or are sent to ensure they are retained before a worker can delete them in an e-mail client. This feature helps organizations address the issues of compliance with laws and regulations governing communications, as well as litigation support. It permits recovery of e-mail in full support of an organization's retention policies. In addition, storage costs are reduced by eliminating the capture of redundant messages and attachments.
The team at RackForce has announced availability of ddsCloud Enterprise, an enterprise-level hosted private cloud solution. RackForce describes ddsCloud Enterprise as a fully virtualized network, storage and compute capacity in an on-demand model that utilizes best-in-class technologies from Cisco, IBM, Microsoft and VMware. Built on RackForce's new state-of-the-art GigaCenter infrastructure, the firm says the results are “unprecedented scalability, flexibility and greenness”. ddsCloud Enterprise leverages virtualization and unified fabric to combine computing, network and storage into one seamless system. When compared with previous computing models, RackForce asserts that it has seen deployment times reduced by 85%, customer costs by up to 30% and a carbon footprint merely 1/50th the size of other cloud offerings located in conventional North American data centers.
The editorial duo of Erik Hatcher and Otis Gospodnetic has updated the book Lucene in Action from Manning Publications to a new 2nd edition. The 500-pager is touted as the definitive guide to Lucene, an open-source, highly scalable, super-fast search engine that developers can conveniently integrate into applications. Since the first edition, Lucene has grown from a nice-to-have feature into an indispensable part of most enterprise apps. The book explores how to index documents; introduces searching, sorting and filtering; and covers the numerous changes to Lucene since the first edition. All source code has been updated to current Lucene 2.3 APIs.
Publisher Wiley calls A History of International Research Networking “the first book written and edited by the people who developed the Internet”, and it covers the history of creating universal protocols and a global data transfer network. Editors Howard Davies and Beatrice Bressan, two veterans of the CERN particle physics research lab, are two of many insiders who contribute with perspectives never before published on the historic, technical development of today's indispensable Internet.
The company cPacket is now marketing the cVu320G network appliance, a solution for data centers, service providers and telecommunications that enables on-demand capacity management, resource allocation and real-time troubleshooting of bursts and spikes. The cVu320G provides complete packet inspection filtering, flexible traffic aggregation, selective duplication and flow-based load balancing, as well as granular, wire-speed performance monitoring for 32 10-Gigabit links. cPacket's rationale for the application is threefold: first, today's data centers struggle with the growing stampede to 10 Gigabit and the increasing virtualization of platforms and services; second, monitoring tools have not kept pace with these developments, and, as a consequence, data centers are being overwhelmed with huge volumes of complex traffic, which they no longer have the visibility to control; and third, the consequences include intermittent and frequent congestion, performance degradation and major service disruptions to end users that are becoming increasingly common. The solution is based on cPacket's unique, 20-Gigabit “complete packet inspection” chips and Marvell's 10-Gigabit Prestera switch.

Realizing the promise of Apache® Hadoop® requires the effective deployment of compute, memory, storage and networking to achieve optimal results. With its flexibility and multitude of options, it is easy to over or under provision the server infrastructure, resulting in poor performance and high TCO. Join us for an in depth, technical discussion with industry experts from leading Hadoop and server companies who will provide insights into the key considerations for designing and deploying an optimal Hadoop cluster.

Built-in forensics, incident response, and security with Red Hat Enterprise Linux 6
Every security policy provides guidance and requirements for ensuring adequate protection of information and data, as well as high-level technical and administrative security requirements for a system in a given environment. Traditionally, providing security for a system focuses on the confidentiality of the information on it. However, protecting the data integrity and system and data availability is just as important. For example, when processing United States intelligence information, there are three attributes that require protection: confidentiality, integrity, and availability.

How to Build an Optimal Hadoop Cluster to Store and Maintain Unlimited Amounts of Data Using Microservers
Realizing the promise of Apache® Hadoop® requires the effective deployment of compute, memory, storage and networking to achieve optimal results. With its flexibility and multitude of options, it is easy to over or under provision the server infrastructure, resulting in poor performance and high TCO. Join us for an in depth, technical discussion with industry experts from leading Hadoop and server companies who will provide insights into the key considerations for designing and deploying an optimal Hadoop cluster.
Some of key questions to be discussed are:
- What is the “typical” Hadoop cluster and what should be installed on the different machine types?
- Why should you consider the typical workload patterns when making your hardware decisions?
- Are all microservers created equal for Hadoop deployments?
- How do I plan for expansion if I require more compute, memory, storage or networking?
