ZFS Second Level ARC - L2ARC - Testing Show 8x More Throughput
Technology that allows ZFS to exploit Flash
A blog posting by Brendan Gregg, co-author of "Solaris Performance and Tools", explains an exciting new ZFS feature L2ARC - the second level ARC.

ARC - Adaptive Replacement Cache - is the algorithm that ZFS uses to keep pages in memory to improve performance). Think of the ARC as that section of DRAM reserved by ZFS for buffering. Brendan observers, "An ARC read miss would normally read from disk, at millisecond latency (especially random reads). The L2ARC sits in-between, extending the main memory cache using fast storage devices - such as flash memory based SSDs (solid state disks)."

Chill-Off! SVLG Data Center Energy Summit: Modular Datacenter Cooling Systems

Java Real-Time System, Version 2.1 Available Now
Available Now - Cool demo given at Java One
The Sun Java Real-Time System (Java RTS) is Sun's commercial implementation of the Real-Time Specification for Java (JSR-001). Implementations of the Java RTS make standard Java technology more deterministic and enable it to meet rigorous timing requirements for mission-critical real-time applications.

After several months of testing, the Sun Java Real-Time System version 2.1 (Java RTS 2.1) is now available. The Java RTS gives users unprecedented control over their Java code execution including thread priorities and whether or not an activity should be interrupted by garbage collection.

JavaFX Script Tutorial Series
Provides the Basic Tools You Need to Get Started
JavaFX Script is a new scripting language that developers can use to create dynamic graphical content. While the language provides libraries on the desktop to help you use the Swing user interface (UI) toolkit and Java 2D APIs conveniently, it doesn't replace either Swing or Java 2D; the goal is to make those APIs more accessible to rich content developers. In other environments, such as mobile systems, JavaFX Script makes use of user interface technologies other than Swing. This tutorial series on JavaFX Script enables you to write visually rich applications that run across platforms and operating environments.

The Sun Datacenter Switch 3x24 (Sun DS 3x24) is designed for smaller and mid-size commercial HPC deployments. This ultra-dense single rack unit Infiniband switching platform binds Sun's blade servers and storage systems into a highly scalable, space-efficient, flexible, high-performance supercomputer. Using the Sun 12x-12x cable it connects directly to the Infiniband Switched Network Express Module complimenting the Sun Blade systems.
Sun Datacenter Switch 3456 and 3x24 Architecture
White Paper Identifies Economies in Interconnect Technology

Among the issues facing designers of supercomputers, choosing the most appropriate interconnect technology -- one that can connect thousands of processors without also introducing severe latency problems -- looms large. Sun's innovative Datacenter Switches, the Sun Datacenter Switch 3456 and the Sun Datacenter Switch 3X24, offer lower acquisition costs, lower latency, very high compute density, greatly reduced cabling and management complexity, reduced real estate needs, and more teraflops per dollar with lower power consumption than with other solutions. The Sun white paper "Sun Datacenter Switch 3456 and 3X24 Architecture" enumerates the virtues of these two solutions.

Ask the Experts: JavaFX Preview
August 18-22
The JavaFX family of products includes the tools and platform SDK that developers, web scripters, and designers need to create dynamic applications for the next generation of web-delivered content. Sun recently released a JavaFX Preview designed to help early adopters become familiar with JavaFX.
