Solaris 10 1/13 Patchset Released and Latest Solaris 10 Kernel PatchIDs
Download Available for Solaris 10 1/13 as Alternative
Oracle has releases a patchset of all the patches contained in Solaris 10 1/13 (Update 11) for both SPARC and x86 systems. The patchset includes an important post-S10U11 patch - 150125-01 (SPARC) / 149637-02 (x86) - and a fix for ZFS Bug 15809921. According to Gerry Haskins' post, this patchset can be applied to any existing Solaris 10 system to bring all pre-existing packages up to the same software level as Solaris 10 1/13. As an alternative to using the patchset, users can instead download Solaris 10 1/12, which will additionally install any new packages delivered in the Update.

ZFS on Linux: Its Day Has Come
Debian, Fedora and RHEL/CentOS -- Ready for Prime Time
The ZFS on Linux project reached an important milestone with the official 0.6.1 release. According to Brian Behendorf, with this release ZoL is ready for wide scale deployment on everything from desktops to super computers. His post on zfsonlinux.org outlines the changes in the community and in the lineup. The new release includes an important feature, "snapdev," which controls the visibility of zvol snapshot devices and may be set to either 'visible' or 'hidden'. To gain access to these devices the property must be set to 'visible' The post also lists the other changes, there are many, in the new release.
ZFS Intent Log: An Overview by Andrew Galloway
Understanding and Using ZFS

Andrew Galloway reconstructs a bit of history in a ZFS Intent Log post as he reviews some of the detail from his now defunct ZIL page in order to bring readers up to date on ZFS. He makes an important distinction between ZFS and ZIL, chiefly that write caching takes place in ZFS, not in ZIL. Given the post's length, it would not be unfair to characterize it as a guide to the use of ZFS if not simply to understanding it. Galloway notes his personal configuration involves running a number of boxes off a ZFS device with no dedicated log.

    SPARC T5-8 Server Delivers World Record TPC-C Single System Performance Results
    Bests the Performance of IBM's Top Contenders
    Oracle's SPARC T5-8 server equipped with eight 3.6 GHz SPARC T5 processors achieved a world record result of 8,552,523 tpmC for a single system on the TPC-C benchmark, demonstrating this world record database performance running Oracle Database 11g Release 2 Enterprise Edition with Oracle Partitioning. This result shows that the SPARC T5-8 server is 2.4 times faster per chip compared to IBM Power 780 three-node cluster results for TPC-C tpmC and is 2.5 times less expensive per $/tpmC. The SPARC T5-8 server delivers 1.4 times better performance than the 32-processor IBM Power 595, at one-fifth the price/performance. This configuration will be available 09/25/13.
    SPARC T5-1B Server Module Outperformance SPARC T4 Processor-based Server
    Running Oracle Communications ASAP at 48% Higher Throughput
    Oracle's SPARC T5-1B server module has delivered outstanding results running Oracle Solaris 11 with Oracle Database 11g Release 2, Oracle WebLogic Server 11g and Oracle Communications ASAP version 7.2. The SPARC T5-1B server module achieved 1,722 ASDLs (atomic network activation actions) per second. With both the application and database tiers consolidated onto a single machine, the SPARC T5-1B server module easily supported service activation volumes of 1,722 ASDLs/sec. Oracle Communications ASAP v7.2 delivered 48% higher throughput on a the SPARC T5-1B server module compared to the SPARC T4-2 server, while the SPARC T5 processor delivered over twice the throughput of the SPARC T4 processor.
    SPARC T5-2 Performance Running Oracle Fusion Middleware SOA
    Delivers 2.1X to 2.4X Improvement in Performance over SPARC T4-2

    Oracle's SPARC T5-2 server running Oracle Fusion Middleware SOA Suite 11g on Oracle Solaris 11 demonstrated an impressive 2.1x to 2.4x throughput improvement with 2x concurrency over a similarly configured SPARC T4-2 server for Fusion Order Demo and Oracle Service Bus (OSB) benchmark workloads using 5 KB message size. Oracle Fusion Middleware SOA was deployed on virtualized environments using Oracle VM for SPARC to demonstrate consolidation of multiple SOA services onto a single system. The benchmark demonstrates SPARC hardware crypto performance within an OSB service using 100-byte element encrypted with AES and signed with RSA128.

    SPARC T5-2 Scores Oracle FLEXCUBE Universal Banking Benchmark World Record Performance
    Processes 25 Million Accounts in 150 Minutes
    A SPARC T5-2 server running Oracle FLEXCUBE Universal Banking Release 12 and Oracle Real Application Clusters (RAC) Database 11g Release 2 processed 25 million accounts in 150 minutes for the End of Month workloads with an average utilization of 55% and 196 minutes utilizing 20 cores with an average cpu utilization of 85%. In 56 minutes this configuration processed 25 million accounts for the End of Day workload utilizing just 20 cores and, further, achieved twice the throughput compared to a SPARC T4-4 server. The configuration processed 10.14 million accounts in 28 minutes with an average cpu utilization of 72% on a single server.
    SPARC T5-8 Delivers Oracle OLAP Perf Version 3 World Record
    Processes 2.93 Million Analytic Queries per Hour
    Oracle's SPARC T5-8 server delivered world record query performance with near real-time analytic capability using the Oracle OLAP Perf Version 3 workload running Oracle Database 11g Release 2 on Oracle Solaris 11. Maximum query throughput on the SPARC T5-8 server is 1.6x higher than the 8-chip Intel Xeon E7-8870 server. The SPARC T5-8 server is clearly able to support at least 600 concurrent users querying OLAP cubes, processing 2.93 million analytic queries/hour with an average response time of 0.66 seconds/query. With a 60 second think time between query requests, the SPARC T5-8 server can support approximately 49,450 concurrent users.
