Which IO Option for which Server?

For those of you who always wanted to know what IO option cards were available for which server, there is now a new portal on  This wiki contains a full list of IO options, ordered by server, and maintained for all current systems. Also included is the number of cards supported on each system.  The same information, for all current as well as for all older models, is available in the Systems Handbook, the ultimate answerbook for all hardware questions ;-)

(For those that have been around for a while: This service is the replacement for the previous "Cross Platform IO Wiki", which is no longer available.)

Hard Partitioning!

Good news for all users of Oracle VM Server for SPARC (aka LDoms) with Oracle Software:  Since December 2, LDoms count as "Hard Partitioning".  This makes it possible to license only those cores of a server with Oracle software that you really need.  Details are available from License Management Services.

Oracle TDE and Hardware Accelerated Crypto

Finally, there's a clear and brief description of the hardware and software required to use hardware accelerated encryption with Oracle TDE..  Here's an even shorter summary ;-)

  • SPARC T4 or Intel CPU with AES-NI
  • Solaris 11 or Linux (a patch for Solaris 10 will be provided eventually)
  • Oracle
    • If you use Linux, Oracle DB with patch 10296641 will also work.

The longer version of this summary is available as MOS-Note 1365021.1

Happy crypting!

Solaris 11 Launch

Core Factor for T4 published

Oracle has published an update to the Processor Core Factor Table that lists the (yet to be released) T4 CPU with a factor of 0.5.  This leaves the license cost per socket the same compared to T3 and puts T4 in the same league as SPARC64 VII+ and all current x86 CPUs.  We will have to wait for the announcement of the CPU until we can actually speak about performance.  But this core factor (which is by no means a measure of CPU performance!) seems to confirm what the few other available bits of information seem to be hinting at:  T4 will deliver on Oracle's performance claims.

Oracle Solaris Studio 12.3 Beta Program

The beta program for Oracle Solaris Studio 12.3 is now open for participation.  Anyone willing to test the newest compiler and developer tools is welcome to join.  You may expect performance improvements over earlier versions of Studio as well as GCC that make testing worth your while.

Happy testing!

Some Thoughts about the new SPARC Roadmap

As most of you know by now, Oracle has recently released an updated roadmap for its SPARC based servers.  Of course, others also publish roadmaps, and we all know how CPUs tend to slip and roadmaps sort of evolve backwards over time.  So what's the value in this new roadmap?

When Oracle aquired Sun, there were all these big promises about increased investement in SPARC and Solaris.  We've already seen the first delivery on these promises:

  • The SPARC T3 CPU doubled the throughput per socket for the T-Series line of servers.
  • Solaris 11 Express gives customers a supported (!) preview of what's coming with Solaris 11
  • M-Series servers can be upgraded yet again for up to an additional 20% performance gain.

All this is shown in the new roadmap as tick-off items.  All this was already well into completion at the time of the aquisition, although the speed with which T3 came to market can already be attributed to Oracle's accelerated investment.  Nevertheless, the real prove point will be the next promise on that roadmap.  It says: "3x Single Strand" for a T-Series CPU.  By now, we all know that the name will probably be "T4".  Rick Hetherington told us a while ago, that the chip will have 8 cores and will execute single threaded workloads up to 5 times faster than T3.  That would be even more than the 3x promised by the roadmap.  The only question that remains is:  Will Oracle deliver?

While no one can tell until the chip and systems are actually announced, chances are good it will.  Why else would Oracle invite customers to participate in a T4 Beta Program?

Back to the original question:  What's the value of this new roadmap?  Well, the foundation of trust, based on delivering on promises, looks good for that part of the roadmap arrow that's already past.  Oracle delivered, and it delivered on time.  That's more than some others can claim.

A little disclaimer to keep everyone happy:  This is my personal view and not an official statement from Oracle.

OVM Server for SPARC 2.1 is here!

The newest version of OVM Server for SPARC aka LDoms is released!  Here's the press release...

What, already a new version again?  Well, the most missed feature in the previous versions was finally completed, and we didn't want to keep everyone waiting ;-)  The new version 2.1 turns "Warm Migration" into "Live Migration".  All the other improvements can be found in "What's New".  Once I have further details about Live Migration, I'll post them here.  You can find the download on MOS and the documentation on OTN.

Erasing disks securely

Actually, both the question and the answer are old and well known.  However, these things tend to be forgotten and pop up as questions from time to time.  Hence a little reminder for all of us:

Solaris makes it easy to erase a disk so that all the data can't be restored, even with sophisticated methods.  There is a subcommand "analyze/purge" in the command format(1M) that does it all for you.  It will overwrite the selected area of your disk (usually s2) a total of four times with different patterns to achieve this.  Of course, depending on the size of the disk, this might take a while.  But it's secure enough to comply with Department Of Defence(DOD) wipe disk standard 5220.22-M.

Some more details are here:

Note that this method does not apply to SSDs of all kind!  And of course, to avoid any risk of losing your data with your disk, simply encrypt it!  It's quite easy using ZFS or Oracle TDE :-)

ILOM for ALOM Users

ALOM ist dead, long live ILOM! The current T3 systems use the new ILOM 3.0.  This version no longer supports the legacy ALOM commands.  That's a change for all those that got used to the alom command syntax over the years.  A table comparing the old and new commands would be helpful.  But where would one find such a table?  In the dokumentation!

But it's not always easy to find what you're looking for right away. To help, here's a link to exactly that table:

What's up with Solaris 11?

Interested in the upcoming Solaris 11?  What will be the highlights?  What exactly is the new packaging format, how does the new installer work?  What do the analysts think?

All this will be covered in the Solaris Online Forum on April 14, starting at 9 am PST.  This will be a live event where you can ask questions. (A recording will be available afterwards.)  Speakers are all high level members of development and product management.

All further details can be found at the registration page.

Logical Domains - sure secure

LDoms Oracle VM Server for SPARC are being used wide and far.  And I've been asked several times, how secure they actually were.  One customer especially wanted to be very very sure. So we asked for independent expertise on the subject matter.  The results were quite pleasing, but not exactly night time literature. So I decided to add some generic deployment recommendations to the core results and came up with a whitepaper. Publishing was delayed a bit due to the change of ownership which resulted in a significant change in process.  The good thing about that is that now it's also up to date with the latest release of the software. I am now happy and proud to present::

Secure Deployment of Oracle VM for SPARC

A big Thanks You to Steffen Gundel of Cirosec, who laid the foundation for this paper with his study.

I do hope that it will be usefull to some of you!
