I've been rather fortunate over the years in that I've not needed to have any formal training in most of the things that I do in relation to IBM Power, AIX, and Linux. But I've now had the opportunity to attend a IBM Redbooks PowerVM workshop. Not because I don't know it, but because I see it as a chance to reaffirm those things I do and ensure I don't have any bad habits or practices. As my job is to advise people the best way to do things, and how to make best use of the tools that these products offer its always good to make sure you're at your best.
Today has been the first part of this 3 day workshop in Madrid, and we have covered a number of things. These are; History of Virtualization, What is PowerVM, Hypervisor, Virtual I/O Server, HMC, Dedicated Processor Partitions, Micro-Partitioning, DLPAR, Shared Processor Pools, Memory Virtualization, Active Memory Sharing and lots more in between. So overall a very comprehensive course.
I've been able to reaffirm a number of key subjects to myself, so 'processor uncapped weight', and recommended CPU minimums in relation to the demand from TCP/IP. As if you've never really had these things explained, you sometimes they just get missed or misunderstood. At the same time I've been able to talk about examples of issues I've seen and offered advise about; such as Virtual Processor and Shared Processor entitlement and its effects on system affinity if not set-up correctly. While also give some tips and pointing out my own blogs covering such subjects as 10Gbe performance and SSDs.
On the whole the first day has been very interesting, and I'm getting to experience the city of Madrid, the people of Spain, but also sample the local food and drink.
