Oracle VM Server for SPARC 3.1.1 Now Available

Oracle VM Server for SPARC
release 3.1.1 is now available. It can be installed on systems with Solaris 11.1 control domains by upgrading to SRU 17.5. That automatically
updates the version of Oracle VM Server for SPARC.

A New Challenge

About two years ago Joyent began offering Linux instances, running under KVM, stored on ZFS, and secured by Zones (“double hull virtualization”). Since then, I’ve been doing more and more work on Linux performance as customers deploy on these instances. It’s been fascinating to work on both the illumos and Linux kernels at the same time (a Linux guest in an illumos host), with full stack visibility of the guests, and hypervisor, down to metal.

Upcoming Classes

I look forward to seeing some of you at an upcoming class.

My class, "Technology Manager's Survival Guide" is on the Friday afternoon training schedule at LOPSA-East on May 2 in New Brunswick, NJ.

The Total Cost of Unmasked Data

Data breaches make headlines at a regular cadence. Each is a surprise, but they are not, as a whole, surprising.

Another 10 Performance Wins

Following on from my earlier 10 performance wins post, here is another group of 10 I have worked on.

The OpenZFS write throttle

In my last blog post, I wrote about the ZFS write throttle, and how we saw it lead to pathological latency variability on customer systems.

The Failed Promise

My dislike for C++ is well-known by those who know me.  As is my lack of fondness for Perl.

I have a new one though.  Java.  Oracle and Apple have conspired to kill it.
(I should say this much -- its been a long time, about a decade, since I developed any Java code.  Its entirely possible that I remember the language with more fondness than it truly warrants.  C++ was once beautiful too -- before ANSI went and mutated it beyond all hope back in 1990 or thereabouts.)

piCorePlayer

I learned that Logitech has brought the Squeezebox product line to end to life. I’m not prepared to replace (or research what might replace) our current audio infrastructure, so I’m experimenting with a piCorePlayer install to see if a low cost, Raspberry Pi solution can solve this problem, much like OpenSprinkler has addressed home irrigation.
