This morning we had an outage and while I did what I could to describe it via text, I can’t seem to come to grips with three unrelated issues occurring together creating so many pages. Why? Our network is segmented/separated by multiple physical segments and these unrelated incidents should not affect the other. This graphic representation isn’t necessarily 100% accurate […]
Yesterday – a very interesting issue cropped up… Another local provider had email warnings being generated that they could not connect to our frontend MX servers. The error itself was: IPv6 is not supported Which is not very clear for a reason email can not be delivered. I mean, my systems are working fine with IPv6 and we have native […]
Been a long week and I had to deal with some red tape internally (of my own creation!), but finally have some working shell service to sell to people who want it. I had posted last week about the issue(s) of shell services and decided that I would do the work to put this kind of service together as I […]
No mispelling, just playing ‘new internet lingo’ game. Did I win? Let’s get serious… This week, multiple customer accounts were breached. Starting approximately 3 weeks ago, a phish was sent out that some of our customers responded to, giving out their account information. We looked through our mail logs and found the users who had been phished and we changed […]
The fun is getting going – ordered up the 8 servers as listed in the configuration in my blog post from October 4th, 2008 on October 14th, 2008. This will give me 8 host systems and one spare on the shelf (I’ll be using it for test deployments and such as well). Ship date: October 16th, 2008. Weight: 862lb Due date: Today! […]
I measured another system at the office today looking at usage on a 2950 with Energy Smart power supplies, and L series processors (50W each). Idle usage was 2.1A, and when I pushed the system as hard as I could to light up 4 cores the system went to 2.9A of power. This is .3A higher than the PE2900 system […]
Time for some power measurements! ESXi was the hypervisor involved in the tests. System installed, 4 virtuals powered on, but not doing anything: 2.2A @115V System installed, 4 virtuals being installed hitting the I/O system: 2.4A @115V System installed, 4 virtuals pushing 100% CPU each, no tuning: 2.6A @115V While the virtuals were pushing the high CPU load, they were also hitting […]
Oh noes, part 3 is upon me and now I must be witty or informative. I am tired today, so I’ll try for informative. My PE2900 showed up today and has been put into the rack. I even have a silly picture of its guts… Wasn’t that nice? Say ‘yes’ please, it helps my ego a lot. Now onto the […]
