By the command below an LPAR can be created with specific WWPNs, of course if you use NPIV adapters. It can be useful for LPARS migration between servers. It is extremely dangerous command, therefore it should be used only by people who knows what is for. Read more of this post

In this post I will describe how to create a Shared Ethernet Adapter (SEA) from the new HMC Enhanced GUI interface where no single command in VIOS command line is required. Read more of this post

Those of you who run recent hardware, probably noticed the new HMC interface called Enhanced+ GUI available since the HMC Firmware 8.8.1 SP1. In this post I would like to share my point of view and give some advice for people who would like to use it. Read more of this post

Few hours ago IBM has released the firmware which enables the SR-IOV functionality on E870/E880 servers.

Last few months months I’m struggling with a speed of a virtual Ethernet adapters. Just buying and configuring 10Gbit adapters in the Shared Ethernet Adapter (SEA) will not boost your network speed to the network heaven. I give you few examples how the speed/bandwidth change for a VLAN, depending from the configuration.

Nowadays, I’m preparing for huge hardware delivery. I’m about to get dozen of MMD’s. The challenge is to configure them (LPAR profiles, VIOS, etc) as soon as possible. I found the way how to automate creation of multiple VIO/LPAR profiles including I/O configuration for multiple servers without knowing SN of the expansions drawers.

Finally the announcement day arrived. POWER8 and SR-IOV have been introduced to the world, and I can share my experience from my last residency.
Single Root I/O Virtualization are not new adapters, but this is a new technology, standard, specification. In fact, it uses adapters which are on the market for some time already. Specification allows to get a slice of a physical adapter and assign it an LPAR. This feature requires a proper hardware, firmware, and all elements around it.

Have you ever think to run your IBM i machine with in IEEE 802.1Q standard, and use the capabilities which offers VLAN tagging? You might heard that your AIX, LINUX colleagues already use it for ages, but for IBM i, this technology is still not available. Well, it is possible! You can trunk multiple VLANs to one physical port, if you configure the POWER Hypervisor to handle this traffic. Read more of this post
