Supporting Women in Open Source

Please have a look at Sage Weil's blog post on supporting the Ada Initiative, which supports women in open source development.

Sage is sponsoring an $8192 matching grant, to support women in open source development of open storage technology.

Oracle VM Server for SPARC 3.1.1.1 Released

A new maintenance release to Oracle VM Server for SPARC has been released, providing
several enhancements described in the
What's New page.
This update
adds support for private VLANs
and
relieves virtual I/O scalability constraints.
This was already announced in the Virtualization Blog,
but the I/O scalability improvement deserves further discussion.

If You're Going to San Francisco... Oracle OpenWorld 2014

Oracle Virtualization at Oracle OpenWorld

There is a rich set of virtualization sessions at Oracle OpenWorld, with presentations by experts, and with customer experience and insight. That starts with the
General Session
with Wim Coekaerts, Senior VP of Linux and Virtualization Engineering, on his virtualization strategy and roadmap.

I recommend the sessions on Oracle Virtual Compute Appliance (VCA).

Modernizing "less"

I have just spent an all-nighter doing something I didn't expect to do.

I've "modernized" less(1).  (That link is to the changeset.)

Goodbye UW IMAP! Hello Dovecot! Oracle Solaris 11 setup guide for Dovecot

After many years of being faithful to UW IMAP it was time to move on. The move was required since UW IMAP was no longer being supported and I was having problems using it with latest version of Horde Webmail, so I decided to install Dovecot on our Oracle Solaris 11 systems.

I was surprised how easy the installation went to get Dovecot working on Solaris 11, which was pleasing.

Tuning the OpenZFS write throttle

In previous posts I discussed the problems with the legacy ZFS write throttle that cause degraded performance and wildly variable latencies.

It's time already

(Sorry for the political/religious slant this post takes... I've been trying to stay focused on technology, but sometimes events are simply too large to ignore...)
The execution of John Foley is just the latest.  But for me, its the straw that broke the camel's back. 

kstat changes in illumos

One of the nice changes to the kstat (kernel statistics) command in illumos is its conversion to C from perl. There were several areas in the illumos (nee OpenSolaris) code where perl had been used. But these were too few to maintain critical mass and it is difficult for interpreted runtimes to change at the pace of an OS, so keeping the two in lockstep is simply not worthwhile.

ZIO Scheduling and Resilver Workloads

Latency and performance problems in storage subsystems can be tricky to understand and tune. If you've ever been stuck in a traffic jam or waited in line to get into a concert, you know that queues can be frustrating to understand and trying on your patience. In modern computing systems, there are many different queues and any time we must share a constrained resource, one or more queues will magically appear in the architecture.
