PowerVM Virtual Ethernet Speed is often confused with VIOS, SEA IVE/HEA speed
I have had a couple of Power systems administrators make assumptions about the virtual Ethernet speed improvements when they install a 10 Gb IVE/HEA in a VIOS which are simply not true. I guess that if three teams have made this mistake then others are about too. So I intend here to put the record straight. The expectation is that (deliberately fully spelt out long-hand to make it very clear): When they upgrade the Integrated Virtual Ethernet (also called a Host Ethernet Adapter) from 1 Gigabit per second to 10 Gigabit per second that the...

High Speed Adapters need Sensible Memory Sizes
AIX or VIOS Start-up Memory Problems I have been working with a couple of customers that have a newly setup AIX Logical Partition (LPAR) that fails to start due to not having enough memory. The common factor is that the LPAR for AIX (or VIOS) includes a good number of what I call "high speed" adapters like 10 Gbps Ethernet, or 4 Gbps or 8 Gbps Fibre Channel adapters. They tend to have multiple adapters of each type for redundancy and throughput. For example, trying to start the LPAR with 1 or 2 GB of memory but it turned out they need... [More]
