The Sun Oracle Database Machine is a million IOPS-capable platform. Why would a CIO consider it as a solution when a particular datacenter may not require so much I/O? Performance Architect in Oracle's Systems Technology Group Kevin Closson gives reasons and applies these to what really goes on in real world production datacenters, touching on chaos, IOPS, latency and Flash.
Specifics about performance tuning and cloud computing figure importantly in the work of Java Champion Kirk Pepperdine, who told Janice J. Heiss that generic advice is useful but only if it is evaluated in terms of particular situations. "Performance tuning," Pepperdine contends, "is still an art where limits are stretched and one goes to places never gone to before. It's an experimental and creative realm with no one-size-fits-all answers to performance problems. It's highly localized."
Sun's VirtualBox and Sun Ray thin clients helped solve Germany travel operator Gebeco's IT environment challenge of maintaining its own OS/2-based reservation software while introducing new software simultaneously, and at a cost savings of nearly US$11,000 per year in electricity. Other benefits Gebeco has experienced with the Sun solution includes simpler and remote maintenance, time savings for administrators, improved failover and overall stability, increased employee flexibility, accelerated client login and reduced heat build up in its offices.
A duel in the Suns of sorts involving a Sun Fire V40z and a Sun Fire X4450 connected back-to-back was performed to discover their ability to exchange UDP or TCP messages with a round-trip latency under 100 ms per message. In addition, both servers were occupied with some business logic, to bring the overall CPU utilization to 60-80% on each machine. Both were running Solaris 10 Update 5 and Java RTS 2.1 (build 1.5.0_16_Java-RTS-2.1_fcs-b11_RTSJ-1.0.2). Frederic Pariente reports the results in his blog "Real Time opens system and network surveillance to Java," a proof-of-concept to evaluate Java RTS 2.1 on Solaris 10.
There is a newfound interest in reselling Sun hardware despite the European Unions investigation into the Sun-Oracle deal, writes John Taylor, Sun business unit director at Interface Solutions. In a column for CRN, Taylor states that wise resellers are realizing the potentially wider benefits of working with Sun post-acquisition by Oracle, and he details why.
A Sun white paper sets out to explain how to maximize the Sun GlassFish Portfolio in the Amazon Elastic Compute Cloud (EC2) public cloud environment, with a focus on running applications using the Sun GlassFish Enterprise Server in the EC2. The Sun GlassFish Portfolio is an open platform based on the Project GlassFish software, an open-source application server that implements Java Platform, Enterprise Edition (Java EE platform) technology.
The Sun white paper "Sun Secure Global Desktop Software: The Adaptive Internet Protocol (AIP)" characterizes the subject software as designed to provide optimal performance over complex network routes with varying bandwidths, employing heuristics to determine the type of device and network connection used and using these parameters to dynamically adapt and optimize performance.
The new Sun Ray Software 5 is now available via download, while the physical media kit is expected to be released December 4th. This release improves the end user experience with a broader choice of end client devices, improved Adobe Flash performance and expanded support for USB peripheral devices. Additionally, Sun Ray Software 5 improves application server support, by adding support for Windows Server 2008. With the release of Version 5, Sun announced the end of life for Sun Ray Software 4 10/08.
Sun Fire X4170 and X4270 Servers along with the Sun Blade X6270 Server Modules to offer 500 GB 7.2K RPM, 2.5-inch SATA disk drive with Marlin brackets. The 500 GB SATA disk drive provides greater on-board storage capacity, making these Sun Fire and Sun Blade servers even better equipped to handle data-intensive applications.
Infiniband IPoIB datalink partition and IP interface configuration is easy and painless using the same network BUI page or CLI contexts as ethernet, says Fishworks blogger Cindi in her update on "Infiniband for Q3.2009." Port GUID information is available for configured partitions on the network page, she continues, which makes it easy to add Sun Storage 7000 Unified Storage System HCA ports to a partition table on a subnet manager.
A five-part Sun Developer Network article series explains how to analyze and troubleshoot OpenSSO deployments with the Mozilla Firefox web browser. Jim Faut along with contributions from Rick Palkovic begin with an introduction and configuration description, followed by these OpenSSO deployment examples: single sign-on and policy protection, cross-domain single sign-on, service provider initiated Fedlet single sign-on and identity provider initiated Fedlet single sign-on.
Sun Distinguished Engineer Glenn Brunette has created a new Solaris 10 Security Deep Dive training mediacast updated for Solaris 10 10/09 or Update 8. Items added to this new version include: ZFS user and group quotas, ZFS pre-defined ACL sets, NTPv4, and nss_ldap shadowAccount support. In addition, there was a bit of cleanup throughout and a new example was added for Trusted Extensions. There is also a recent update to Immutable Service Containers (ISC) for OpenSolaris 2009.06.
