First Come…First Serve

30 08 2010

I don’t know if this is an improvement over the old session system or not!!!

So far…the sessions have been a bit too marketing heavy for my taste. I’m an engineer…”where’s the beef!!!” In any case…here’s my thoughts on the sessions I’ve attended thus far:

SP9649 – Imagine Virtually Anything w/ NetApp, Cisco, and VMware: This was unfortunately not much more than hot air. Nothing of real substance here…only some drivel about how much one could save by utilizing such a system. Also…it was our first glance at what’s looking to be the main theme here…”IT as a service!!!” They completely glazed over some real deployment problems and security issues inherent with deploying vFilers in a cloud service provider environment.

SS1055 – Partner Track Super Session: A little more marketing here…but there were some tidbits to take from this session. One, and I’ve felt this way for a while, it’s clear to me that VMware is hot and heavy in their move toward acquiring the mindshare, resources, and capabilities to directly sell cloud computing to end users. Even if they might say this is not the case…I can’t shake the feeling that this is the case.

ALT3003 – VMware vSphere Performance and Tuning: This is the first non-marketing session that I’ve attended this year. Notes as follows: This session is based on Lab #24 in the Self-Paced labs area. Session begins by talking about Storage I/O control. Statement made that storage is best when <30ms of latency. Unfortunately… (lack of sleep is catching up to me in this session 🙂 ) SIOC control normalized latency. In vSphere 4.1 we can also set IOPs limits. Value is per disk. 2ms kernel latency should be the max you should see… "A little bit of a glitch"…can't display real-time stats for a VM…Yeah…little glitch…too bad I see it all of the time. Turn on Mem Compression Mem.MemZipEnable (Enabled by default on vSphere) They say to be mindful of NUMA…but they don't really elaborate… Swap in rate should be watched… Should force hardware assist on AMD 32-bit guests… They talk about dropping off in increasing vCPUs in VMs…but leave off the drop from 8 vCPUs. Nothing magical in the vCPU performance management… 2000ms is a problem according to this session.





VMworld Check In

29 08 2010

Well, things didn’t start off so well today. First of all, although it’s great that this year VMware is running regular shuttles between the Moscone and the approved hotels in the area…we struggled trying to actually get on one. No less than three buses passed by the stop outside our hotel, even with the VMware guy trying to flag them down. Well…all of the members of my team were anxious to get registered, so we all decided to begin walking down to the Moscone on foot. Not a terrible walk from the hotel to the conference center…so not the end of the world.

Upon arriving at the Moscone, the line for registration was already quite long, but luckily it got moving pretty fast once the registration opened up. Once we received our badges we made our way down to the materials room to pick up our inevitable schwag bags. Welcome to line #2:

After waiting a few minutes to get in…I got to pick up my bag, but these yahoos didn’t have me down as being a VMUG member…which I most certainly am. Darn it!!! Oh well…hopefully the rest of the week turns out better!
