The Issue in Detail

Supertape Performance Paradox
With a native throughput rate that's 20% slower than IBM's LTO3 drive, 
many will look at the specs for the new DLT-S4 (a.k.a. 4th generation 
SDLT) tape drive and wonder why it's super. Running our standard 
benchmarks we confirmed this relationship and joined the skeptics. 
Nonetheless, when backup tests consistently finished 30% faster using the new 
drive, we went to work on writing new tape benchmarks, now available on the 
openBench Labs site,. Learn how the DLT-S4 streams slower to run 
faster. 

Driving a Grid by Policy
For grid computing as a service-oriented architecture (SOA) to reach 
its potential, the commercial software that orchestrates discovery, 
coupling, and management of services in the grid needs to be just as 
Interoperable as the services themselves. To insure that future, leaders of 
the Apache Web Services Project and commercial SOA software vendors are 
developing an open source framework for the mediation of Web services. 
Dubbed "Synapse," and placed in the Apache Software Foundation's 
incubator for Web services, the SOA mediation framework is intended to foster 
greater reliability and resiliency for grid computing. Learn why 
Gartner sees such open-source middleware as proof that "open-source 
technology will have a massive impact on application integration."

Note to Readers:  

A growing number of articles in Open, such as the new article on grid 
computing, are now in the form of hyperlinks to other sites. In all 
cases, these articles will have been created by Open. Open is rapidly 
expanding its role as a creator of technical IT features for a growing 
number of partners in areas such as RFID, systems management, and storage. 
As we expand these content-based relationships, we'll be linking only to 
those features that directly relate to Linux and open source.

>From time to time, you may also receive email from some of our 
partners, for whom we create technical content, that reference both Open and a 
partner's site. Any future mailings will always include a reference to 
Open. That reference to Open reaffirms that we never sell our 
subscription list. All authorized emails will always be under the control of 
Open. Your circulation data is never transferred to any vendor. So we 
invite you to read and assess these email messages from IBM, HP, PEAK 
Technologies, or other OPEN partners, with the confidence that your email 
data remains safe and secure with us.
