Rackable Delivers Servers for High-Density Datacenters
BLADE SERVERS OFFER GOOD BANG FOR YOUR BUCK IN terms of datacenter real estate, but they also limit flexibility. Rackable Systems' Scale Out Series server line hopes to give IT managers the best of both worlds, by offering blade density with the benefits of traditional rack-mount server design. Each Scale Out cabinet enclosure has room for as many as 92 servers, with an additional 19 inches of rackmount space for networking equipment. The servers support both Intel and AMD CPUs in either single or dual-processor configurations, and each includes one full-height PCI-X expansion slot. Both in-band and out-of-band management systems are available. Rackable will engineer and configure systems to order, running a wide range of operating systems and software.

.Net Transaction Tracing
Companies that rely on .Net-based Web applications can identify performance bottlenecks with Tonic Software's WebLens for the Microsoft .Net Framework. Similar to the company's existing product for J2EE applications, WebLens for .Net can trace transactions across multiple servers, clusters, and Web services, with granularity down to individual method calls. The software remains dormant until requested, adding no measurable overhead while in dormant mode. Pricing for turnkey solutions starts at $23,000.

Turbocharged IP WAN
IP-based WAN links aren't always the most efficient way to conduct high-volume data transfers such as storage network mirroring and replication, data warehousing, high-resolution imaging, or digital video. But with the release of Hyperl P R5, Network Executive Software claims it can transparently accelerate such transfers three to 10 times normal speeds, for as much as 480Mbps total bandwidth. Enabling compression can increase speeds even more, depending on the data transmitted. Pricing starts at $19,750.

Hybrid Directory Integration
Consolidating data from multiple directories, databases, and applications is a crucial part of any identity or portal project. The usual answer is either a metadirectory or virtual directory solution. Now Radiant Logic says its RadiantOne 4.0 combines the best of both categories. RadiantOne combines a virtual directory with Synchronization Services that duplicate metadirectory functionality. The new version adds persistent caching, group and role virtualization, new synchronization tools, and speed optimizations. Pricing starts at $50,000.

Cut Through Code Complexity
Logic Explorers' CodeLogic 2.0 belongs to a species of tools I refer to as "interactive diagrammers." Point CodeLogic to a collection of Ct or Java source files, and the tool will crawl through them, organize what it discovers, and present you with several graphical views built from what it's learned.
The views it offers include the familiar UML (Unified Modeling Language) class and sequence diagrams, as well as a novel flow diagram that, at first glance, appears to be merely a glorified flowchart but which is in fact a useful, interactive graph. You can, for example, jump to the location in source code corresponding to any node in the diagram. You can also "backtrack" variables, which causes the diagram to trace the flow of control that a variable will pass through from its inception. This feature was not working in the C# version of CodeLogic 2.0 I tested, but I did see it in action in the Version 1.5 for Java edition. (CodeLogic engineers assured me that backtracking would be fixed in the C# edition by release time.)
CodeLogic's diagram generation is entirely automatic. The tool requires only the location of your source code. So, when you define a new project, you're actually defining the directory holding the source files. (This functionality means that you can add new files to the project simply by depositing the source files in the proper directory.)
CodeLogic 2.0 also comes with a plug-in for Visual Studio. Set your cursor inside a method in source, click on one of the buttons CodeLogic adds to the toolbar, and off you go. Although there are some rough edges to CodeLogic, it does make reverse engineering C# or Java code - acquired or inherited - vastly simpler than spelunking through unfamiliar source.
