Oracle Processor Core Factor Table
Includes SPARC T5 and M5
Oracle pricing for Multi-core processors are priced as (number of cores)*(multi-core factor) processors.

The "Oracle Processor Core Factor Table" has been updated in order to include SPARC T5 and M5. It's 0.5 for both.

How Oracle Solaris Engineering Thinks
Solaris Engineer Liane Praza Pulls Back the Curtain
In two brief videos (both about two minutes long) recorded at Oracle Solaris Innovations Workshop, Solaris Engineer Liane Praza explains why Oracle Solaris engineering continues to build virtualization capabilities into the OS instead of adding more features and better management to the hypervisor and then explains what it is about Solaris that makes it such a good platform for managing virtual machines . As Rick Ramsey notes, this is a perfect opportunity to glimpse how Oracle's engineering staff think about Solaris and the other solutions that emerge from their shop.
Massive Solaris Scalability for the T5-8 and M5-32
By Steve Sistare
Steve Sistare writes, "How do you scale a general purpose operating system to handle a single system image with 1000's of CPUs and 10's of terabytes of memory? You start with the scalable Solaris foundation. You use superior tools such as Dtrace to expose issues, quantify them, and extrapolate to the future. You pay careful attention to computer science, data structures, and algorithms, when designing fixes. You implement fixes that automatically scale with system size, so that once exposed, an issue never recurs in future systems, and the set of issues you must fix in each larger generation steadily shrinks.

The T5-8 has 8 sockets, each containing 16 cores of 8 hardware strands each, which Solaris sees as 1024 CPUs to manage. The M5-32 has 1536 CPUs and 32 TB of memory. Both are many times larger than the previous generation of Oracle T-class and M-class servers. Solaris scales well on that generation, but every leap in size exposes previously benign O(N) and O(N^2) algorithms that explode into prominence on the larger system, consuming excessive CPU time, memory, and other resources, and limiting scalability. To find these, knowing what to look for helps."

Solaris 11 outperforms RHEL 6 on 2 socket Intel servers
Compare SPECjbb on servers with same Intel chips
Along time Sun employee writes, "I've often heard the term "Slow-laris" applied to Oracle's premier Unix operating system. Most frequently this was in comparison to the Linux OS running on small two socket servers. I will admit that in the Solaris 8 and 9 timeframe engineering decisions were made to benefit scalability to 64 sockets that sometimes penalized smaller servers. In addition, because of Solaris long history and derivation from ATT and BSD Unix code, there was undoubtedly a bit of code labeled, "if it ain't broke, don't fix it."

With the advent of Solaris 10 and Dynamic Tracing, (DTrace) we actually hunted down and killed a number of those legacy code segments using a new philosophy labeled internally, "If Solaris is slower than Linux on the same hardware, it's a bug."

As a result, Solaris 11 provides higher performance than Red Hat Enterprise Linux 6.3 on basically identical 2 socket hardware as measured by the SPECjbb benchmark..."

Disk Timeouts and ZFS Clients, Especially VM Clients
By Andrew Galloway
Andrew writes, "A pretty common issue to run into when using some SAN back-ends for virtual machines is that the VM's end up crashing, BSOD'ing, or (most commonly) remounting their "disks" read-only when there's a hiccup or failover in the storage system, often resulting in a need to reboot to restore functionality.

The most common fix is typically to increase the default timeout settings in the guest VM, and sometimes also in the host machine as well, as the root cause is usually that the SAN took longer than the default timeout to respond. This is usually because the SAN was involved in a failover, which can take > 60, or even > 120 seconds in some cases. I generally recommend setting it to at least 180 seconds, though 300 seconds or more I'm also perfectly happy with, personally. I only really have an issue with under 120 seconds."

    Guidelines for Deployment in a Virtualized Environment
    Oracle Virtual Networking
    Oracle Virtual Networking offers advantages for virtualized server environments. With server virtualization, the bandwidth, network diversity, and storage performance requirements for the physical hosts can be accommodated by using multiple virtual NICs (vNICs) and virtual HBAs (vHBAs), all of which are delivered over a single pair of cables connecting to a purpose-built fabric. These resources can be added or changed on the fly without disrupting service, making it easy to virtualize new applications. The networking resources can also be configured such that they communicate directly across the fabric, allowing for unprecedented server-to-server performance.

    In this article, we will examine guidelines and best-practices for deploying Oracle Virtual Networking in a virtualized environment. The recommendations focus on bringing the most simplicity, agility, and performance to the environment. This article is not a replacement for the official documentation; it is a supplement. It is assumed that readers are familiar with the administration of virtualized environments and the basic concepts of Oracle Virtual Networking.

    How To: Migrating Virtual Machines
    A Collection of Guides to the Process
    A major advantage available to users of Oracle VM Server for x86 or SPARC, Owen Allen writes, is the ability to migrate virtual machines. If two Oracle VM Servers are grouped together in a server pool under one Oracle VM Manager, users can perform a live migration to move an Oracle VM to a new server without shutting it down. There is now a collection of helpful guides to the process of VM migration that Allen provides links to in his post. These include a how-to, the Feature Reference Guide, and the How-To library itself.
    VirtualBox 4.2.12
    maintenance release

    The Role of Oracle VM Server for x86 in a Virtualization Strategy
    Evaluating the Components and Operation of a Virtualized Environment
    "The Role of Oracle VM Server for x86 in a Virtualization Strategy" is Matthias Pfützner's contribution to the series on virtualization. He considers the roles of both Oracle VM Manager and Oracle VM Server. He goes on to suggest that, given the complexity of large virtualization environments, a careful evaluation of TCO and/or ROI analysis is essential. As the underlying infrastructure becomes more and more a commodity, elements at higher levels become more and more important in the decision-making progress, and getting the "commodity" part from the same vendor that is supplying the higher-level elements might become an advantage.
    The Role of Oracle Virtual Desktop Infrastructure in a Virtualization Strategy
    Part 7 in a series of virtualization articles
    This article, which is Part 7 in a series of virtualization articles, describes how Oracle Virtual Desktop Infrastructure provides multiple end users with individualized desktops that are hosted over the network from a centrally located computer or server.

    Now that we've finished the overview of individual virtualization technologies from Oracle using hypervisors and operating system features, it's time to look at the desktop virtualization product known as Oracle Virtual Desktop Infrastructure.

    Java on SPARC T5-8 Servers is FAST
    by Tori Wieldt
    Tori Wieldt writes, "Watching the boats practicing on San Francisco Bay for the America's Cup reminds me that fast is fun! Did you know that Oracle just announced world record Java benchmarks with SPARC T5 and Solaris?

    Oracle produced a world record SPECjEnterprise2010 benchmark result of 57,422.17 SPECjEnterprise2010 EjOPS using Oracle's SPARC T5-8 server in the application tier and another SPARC T5-8 server for the database tier. This result demonstrated less than 1 second response time for all SPECjEnterprise2010 transactions, while demonstrating a sustained load of Java EE 5 transactions equivalent to 468,000 users. A SPARC T5-8 has 8 chips, 128 cores, and runs a 3.6 GHz SPARC T5CPU. Translation: If you get some SPARC T5-8 servers, you can run your Java applications really, really fast..."
