The DCX man has retired.

In 2008 Brocade announced the 8G director class switches DCX and DCX-4S. A rather impactful release of a new piece of hardware where the next generation FC ASIC saw light. The Condor.The marketing department of Brocade back then had probably been smoking something as the introduction of the platform was accompanied with a rather cringy “Marvel-like” super-hero called DCX-man. (uhhhhh… shivers….)

HBA Firmware and Drivers – The Storage Grey Area

Whenever things goes haywire on an OS or application there are two areas that are looked at first:

  1. Networks
  2. Storage

In a fair few cases the issue is founded to be external from the host systems but when it comes to performance related problems from a storage perspective the entire IO-stack is at play.

Crackdown on FOS support

If you’ve read my articles over the last decade or so you’ve seen I’m keen on maintenance. Both from a physical hardware as well as software perspective a storage environment needs to be kept in tip-top shape at all times.

BNA before 14.4.1 is no longer supported

I’ve already mentioned that BNA was End-of-Life and will/is (be) replaced by SANNav.

Preventing client DNS leaking on OpenWRT

A while ago I wrote an article whereby I provided an OpenDNS resolver server via DHCP to the computers, tablets and phones of my kids. (See here). This worked very well and I have been able to keep the nastiness of the web out of sight. Plus it gave me the option to block certain sites which were not captured under a certain category or, if those domains fell under a category that also included a lot of useful domains, exclude them.

Brocade Network Advisor (BNA) is End-of-Life

So the final nail is in the coffin. Brocade Network Advisor is being put to rest. The juggling of Java code to the ever expanding demand of functions, features and other capabilities was no longer sustainable. Oracle starting to charge for Java would’ve made the decision even easier.

The replacement is SANNav (No I don’t get into the same discussion VMWare has with which character should be capitalized or not. :-))
