Making Clusters Easier With Sun InfiniBand Technology
A Standards-Based Interconnect for Application Scalability and Network Consolidation
The Sun white paper "Making Clusters Easier with Sun Infiniband Technology" explains the advantages to be found in using Infiniband technology for HPC implementations that need to scale. In its introduction to InfiniBand technology, the paper focuses on its ability to scale application performance and consolidate network infrastructure.
DTrace and the Linux bunker mentality
System Tap Just Doesn't Appear to Have It
Paul Murphy (for one) ponders the reluctance of the powers that be at Linux to provide a DTrace port, as Apple, QNX, and the FreeBSD project have done. He blogs on the subject, bringing in DTrace developer Brian Cantrel for backup. An open source Sun product that made its debut with Solaris 10, DTrace "has since been ported to MacOS X and various other BSD derivatives. IBM is reported busily copying it into AIX (along with containers, zones, and whole bunch of other things they ridiculed when Sun introduced them"), Murphy writes.

Access Control Lists on Solaris OS with ZFS
Blogger Ben Rockwood Provides Some Clarity
If you're looking for Solaris ACLs, you might want to have a glance at Ben Rockwood's blog on the subject of when to use POSIX and when to use NFSv4 in your search. Ben's quick summary is:

  • There are TWO types of file ACL's in Solaris: POSIX and NFSv4
  • NFSv4 ACL's are very granular and powerful
  • ACL's are a pain
  • NFSv3 ACL support (POSIX) does not work when sharing a ZFS filesystem; Use NFSv4
  • GUI's are an ACL's best friend, sad but true
  • Avoid them if you can, but if/when you need them, they are there

Sun SPARC Enterprise Server Family
The Key to High Availability and Lower TCO in the Datacenter
The Sun white paper “High Availability in the Datacenter” considers the role of the Sun SPARC Enterprise M4000, M5000, M8000 and M9000 servers in reducing TCO for IT departments while also delivering an end-to-end solution for helping organizations realize the most demanding availability requirements. With Sun SPARC Enterprise servers, Solaris Cluster software, XSCF Control Package firmware, Sun Management Center software, and an extensive line of enterprise-class services and training, minimizing TCO becomes a reality.
Improved Versions of the Sun SPARC Enterprise Servers
A 30-minutes NetTalk with Tom Atwood
Tom Atwood, Group Manager at Sun had a Nettalk presentation that briefed Sun users on Improved Versions of the Sun SPARC Enterprise Servers. Atwood includes how the Mseries has broken world records and he included graphs and a scaling run down of the size of the different Mseries servers and their usage strong points.
Sun Netra T5220 (AC/DC version) ATO Program
High Throughput, Low Power Consumption in 2U Form Factor
Sun offers the Sun Netra T5220 ATO (assemble to order) in both AC and DC versions. The server is based on the second generation of Chip Multi-threaded Technology (CMT) UltraSPARC T2 processor with up to 8 cores with 8 threads per core. This is the first processor to increase performance by scaling with threads, rather than frequency, minimizing power consumption. The Sun Netra T5220 offers extreme reliability and high throughput, at the same time offering processor core, memory and I/O densities to enable expansion and flexibility within a compact 2U form factor. All of this makes the Sun Netra T5220 the ideal platform for virtualization and a good replacement/alternative to the Netra T2000 or the Netra 240 and Netra 440.

Making Use of Virtual Tape in a Disk to Disk to Tape (D2D2T) Environment
Clipper Notes White Paper
"A D2D2T infrastructure allows the archival and non-critical data to flow out to a lower cost and lower energy medium (tape), while delivering backup and recovery performance to meet enterprise SLAs for the VTL. A D2D2T environment also enables the data center to retain older back-ups for a longer period without a significant impact on the TCO," writes David Reine, an analyst for The Clipper Group, in a white paper about making Use of Virtual Tape in a D2D2T Environment.

David concludes that, "a VTL alone cannot satisfy all of the demands of a modern data center, mall or large. A D2D2T solution, however, can provide your data center with all of the latest standards in data protection as it delivers high performance, high capacity, and reliability, while controlling the TCO of the IT infrastructure."

Oracle 10g ASM Best Practices with Hitachi Replication Software
Pairing Demonstrates Excellent Backup and Recovery Performance
Hitachi Data Systems and Hitachi, Ltd., have tested and evaluated guidelines and backup and recovery best practices for using Automatic Storage Management (ASM), a new feature introduced in Oracle Database 10g, to simplify Oracle database file administration on the Hitachi Universal Storage Platform family of products while optimizing performance. Results are reported in the 42-page Hitachi-Oracle application brief "Oracle Database 10g Automatic Storage Management Best Practices...."

"Oracle Database 10g ASM provides storage cluster volume management and file system functionality at no additional cost. ASM increases storage utilization, performance, and availability while eliminating the need for third-party volume management and file systems for Oracle database files. As a result, ASM provides significant cost savings for the data center."

    Security Vulnerability in the DNS Protocol may lead to DNS Cache Poisoning
    Remote Unprivileged Users Can Return Incorrect Internet Addresses
    This Sun Alert, "Security Vulnerability in the DNS Protocol may lead to DNS Cache Poisoning," cautions against a security vulnerability in the DNS protocol that may allow remote unprivileged users to cause named(1M) to return incorrect addresses for Internet hosts, thereby redirecting end users to unintended hosts or services.
    Managing Security in an Open World
    change title, add subtitle
    Leslie Lambert, Sun's chief information security officer, spoke with Al Riske for an article entitled "Managing Security in an Open World." Riske characterizes Lambert's job as "managing a paradox," and a worldwide one at that.

    With a community of users (including Sun resellers and partners) that numbers in the neighborhood of 80,000, Lambert and her staff have plenty of "friends," who need access in order to do their jobs.

    Riske reports that Sun has more than 4,000 bloggers, more than 6,000 Facebook friends, and no fewer than seven islands in Second Life, and that it has staged numerous public and private events on the site, including a virtual town-hall meeting involving Sun's top executives in avatar-to-avatar interactions with employees around the world.
