T4 arrives!

A natural question for SPARC and Solaris customers would be "should I use a T4, a T3, or an M-series product?" Now that T-series has a broader range of applicability, there's more choice in platform selection: a T4 can be used in cases where M-series would have been the only answer. There's more overlap.

In general, the M-series will still have the advantage for vertically scaling workloads that need massive CPU, memory, and I/O capacity, that need the higher redundancy and reliability features, and depend on the ability to add capacity to a running system by inserting CPU boards when needed. The T3 product will still find use in pure throughput computing applications because it has the higher core density and lower software license core factor (0.25 instead of 0.5).

The T4 processor and the servers based on it mark a new level of performance for SPARC processors. With record performance it changes the game (and turns over stale assumptions) about SPARC performance. It also illustrates the commitment Oracle has to SPARC and Solaris, and our increased ability to execute on delivering faster system products. By adding single CPU performance to T-series, it extends the ability to leverage Oracle VM Server for SPARC (LDoms) for a broader range of applications. Big news indeed - and Oracle Open World is just starting up, so watch Oracle.com and blogs.oracle.com closely the next few days.

Oracle Takes The Midrange Fight To IBM

Just like IBM lowered the boom on Sun back in the early 2000s with its AIX on Power ramp--made possible because IBM charged AS/400 shops exorbitant prices for hardware and software so it could discount AIX boxes insanely to win over Sun shops--Oracle is going to lower the boom on IBM and Hewlett-Packard in the portion of the server racket that is devoted to running Oracle, PeopleSoft, Siebel, JDE, and other applications. This time around, Oracle will be making deals on its database, middleware, and application software to help it push its iron. Mark my words. Larry Ellison is not joking around here; he was just waiting for the chip engineers to get the right processor out the door.

Very roughly speaking, I would guess that this Sparc cluster should have roughly the same performance as a Power 770 running database workloads, but it could be higher because of the compression and SQL pre-chewing of the Exadata storage arrays and the flash integrated into the Sparc T4-4 nodes when used in the SuperCluster.

Oracle previews Solaris 11, due in November

Fowler did not give the precise number of cores, threads, or memory capacity that Solaris 11 would span, but said Oracle took the time to rework the Solaris kernel with a new scheduler and a new I/O handler that would allow it to span tens of thousands of CPUs, hundreds of terabytes of main memory, exabytes of storage, and hundreds of gigabits of networking bandwidth. (In past presentations of the Sparc/Solaris roadmap, Fowler showed the design goal of a future Sparc system due in late 2014 or early 2015 as spanning 64 sockets in a single system image with a total of 16,384 threads and supporting 64TB of main memory.)

Solaris 11 has support for the dynamic threading implemented in the new Sparc T4 processors, launched last week, and also sports a latency-aware kernel memory allocator, an optimized shared memory stack, a parallel network stack, adaptable thread and memory placement, and enhancements in NUMA I/O (which will be important in future Sparc T series machines, presumably). The scheduler is aware of the different possible topologies in both x86 and Sparc systems and has NUMA-aware kernel memory fan out.

Fowler also said that 600 customers had Solaris 11 running in production already. Presumably he meant actual Solaris 11, not Solaris 11 Express. And he reminded OpenWorld attendees of Oracle's compatibility guarantee for Solaris applications: "Your applications will run on 11 or it is my problem."

Oracle Has Built A Modern, Cloudy AS/400

I've been thinking a lot lately about the juxtaposition of Oracle's "engineered systems" and IBM's "workload optimized systems," not just because these things are grabbing headlines, but because all the major system makers are trying to figure out a new way to sell a very old idea: machines designed to do very specific work rather than being general purpose systems. Only this time around, more than a few of them are trying to make these engineered systems out of commodity processors, memory, disk, flash, and networking components. The secret sauce--and the profit--in each one of them is not the hardware, but how a collection of hardware supports a very specific stack of application software.

If I were Larry Ellison, I would start pitching the cloud against on premise entry servers or build some baby clusters--probably both. Either could mean big trouble for Big Blue and its Power Systems business.

Solaris 10 8/11 (Update 10) Patchset now available

As you may know by now, these patchsets will bring all pre-existing packages up to the same software level as the corresponding Solaris Update. For example, all ZFS and Zones functionality is entirely contained in pre-existing packages, so applying the patchset will provide all the ZFS and Zones functionality and bug fixes contained in the corresponding Solaris Update.

When we release the Solaris Update patchset, we try to fix any serious late breaking issues found with the corresponding Solaris Update patchset. A list of additional patches added and the Caveats they address is contained in the patchset README.

Applying the patchset is not the same as upgrading to the Solaris Update release, as the patchset will not include any new packages introduced in the Solaris Update or any obsolete packages deleted in the Update.

Solaris 9 transitioning to Extended Support

Just a quick heads-up that Solaris 9 will transition to Vintage support (old sun terminology) / Extended support (Oracle terminology) at the end of this month.

Solaris 9 patches released from November 1, 2011, will have Vintage/Extended access entitlement by default, which means that only customers with an Extended Support contract for Solaris will be able to access them.

Oracle Solaris 11 Highlights from Oracle OpenWorld 2011!

Oracle Solaris 11 had some exciting news at Oracle OpenWorld 2011 this year! If you missed the John Fowler keynote or the Oracle Solaris 11 sessions - you can still catch all the highlights from links below.

What's New in Oracle Solaris 11

Oracle Solaris 11 adds new features to the #1 Enterprise OS, Solaris 10. Some of these features were in "preview form" in Solaris 11 Express. The feature sets introduced there have been greatly expanded in order to make Solaris 11 ready for your data center. Also, new features have been added that were not in Solaris 11 Express in any form.

The list of features below is not exhaustive. Complete documentation about changes to Solaris will be made available. To learn more, register for the Solaris 11 launch. You can attend in person, in New York City, or via webcast.

That Perplexing Power7+ Processor

What IBM is telling business partners is that the old Power7 machines and the new Power7 machines are essentially the same except for the memory and I/O capacity differences--including essentially the same price. They have the same software editions riding on top of them and for most customers, according to Big Blue, either machine will work fine. Those who have high-bandwidth networking and storage needs will want the newer machines, or those that are doing lots of virtualization or other memory-chewing workloads. At around $200 per GB, that extra memory is not cheap, so not everyone will want to go there anyway. In 2012, IBM told business partners, it will start pushing the fatter Power7 machines and later in the year it will withdraw the older boxes. The key thing, IBM told resellers was DO NOT DISRUPT 4Q11 SALES.

As I point out elsewhere in this issue, if you are buying one of the skinnier Power Systems from last year's catalog, you should demand some kind of compensation. There's no way the older machines are of the same value on the street with smaller potential memory and slower I/O. It probably isn't much of a difference, but there's no way it can be zero.

This newsletter advocates for Power Systems customers and it wants IBM to do more than worry about fourth quarter sales. It wants IBM to start taking a more aggressive technical fight to Intel so all of us in the IBM i ecosystem can do better.

Using SystemTap

While using SystemTap, I’ve been keeping notes of what I’ve been doing, including what worked and what didn’t, and how I fixed problems. It’s proven a handy reference.

In some recent threads about DTrace, people have asked how it compares to SystemTap – with some commenting that they haven’t had time to study either. I’ve been encouraged to post about my experiences, which is easy to do from my notes. I could (and probably should) get some of these into the SystemTap bug database, too.

What I’m sharing are various experiences of using SystemTap, including times where I made mistakes because I didn’t know what I was doing. I’ll begin with a narrative about tracing disk I/O, which connects together various experiences. After that it gets a little discontiguous, clipped from various notes. I’ll try to keep this technical, positive, and constructive. Perhaps this will help the SystemTap project itself, to see what a user (with a strong Dynamic Tracing and kernel engineering background) struggles with.

Using Oracle Ksplice to Update Oracle Linux Systems Without Rebooting

Oracle Ksplice is an exciting new addition to the Oracle Linux Premier Support subscription. Oracle Ksplice technology allows you to update systems with new kernel security errata (CVE) without the need to reboot, which enables you to remain current with OS vulnerability patches while minimizing downtime. Oracle Ksplice actively applies updates to the running kernel image, instead of making on-disk changes that would take effect only after a subsequent reboot.

Another requirement for getting Oracle Ksplice updates is the use of the Unbreakable Enterprise Kernel from Oracle. The lowest Oracle Linux kernel version at the time of this writing is 2.6.32-100.28.9. This kernel (and newer) can be installed on both Oracle Linux 5 and Oracle Linux 6 distribution versions. Customers with Red Hat Enterprise Linux (RHEL) 5 and 6 can do the simple migration to Oracle Linux and apply the packages on their existing installation of RHEL. Oracle does not offer Oracle Ksplice for Red Hat compatible kernels.

How to Create a Customized Oracle Solaris 11 Image Using the Distribution Constructor

This article describes how to create customized Oracle Solaris 11 images that contain customized software.

A brief overview of the reasons for creating a customized Oracle Solaris 11 image is provided. Relevant concepts are introduced, followed by a real example of using the Distribution Constructor to create custom ("golden") images. The example concludes with an illustration of taking the created image and making it available for consumption by systems as part of the provisioning process.
