10 GBit Ethernet: Resources grab bag
As 10Gbit Ethernet (10 GbE) hits data centres around the world, you'll need to know how to optimise it. There are a few superb resources available. IBM PowerVM Technical Webinars - Virtualisation and the World of 10Gbit Ethernet The excellent Webinar Series on Power Systems Virtualisation from IBM has free monthly sessions on Virtualisation. Mr NMon himself -- a.k.a. Nigel Griffiths -- presents some of them. Each webinar runs for about an hour and has an accompanying set of slides. If the UK time zone makes the webinar difficult for you to... [More]

HMC V7R7.2.0 allows dynamic VLANs on Power7
The HMC V7R7.2.0 has been released and it includes a feature which has long been in demand: the ability to change VLANs dynamically on virtual ethernet adapters. Hooray! The documentation for the HMC release notes explain that this feature is for Power7 servers only: The chhwres command has been enhanced to support dynamically changing the properties of a virtual Ethernet adapter which is assigned to a running partition ( POWER7 servers only) . The properties that can be changed are the IEEE 802.1Q setting, the virtual LANs , and the... [More]

IVM to HMC Migration - a Customer's Experience
In September 2009 Rob McNelly wrote on his AIXChange blog about Migrating from the IVM to the HMC . I have documented my own experience of this procedure. You can download it from here , at a very affordable price of USD 0.00 (no refunds). The IVM or Integrated Virtualization Manager, is a browser interface to the VIO server on smaller systems, and it has HMC-like functionality, such as Dynamic LPAR, the ability to configure LPARs, stop and start them and so on. The HMC (Hardware Management Console, as you know) is able to manage several... [More]

Turbo charge inter-LPAR communications using super jumbo frames
REV UP YOUR VIRTUAL ETHERNET There
are a few strategies for speeding
up communications between LPARs on the same physical server. One of
those is using virtual adapters. Those virtual adapters can run
at high speeds. You can turn on this turbo-charge feature by setting the
MTU size to 65280 Bytes, which are actually SUPER jumbo frames, according to Wikipedia . Whatever that means, it sounds good, doesn't it? The transmission speed of Virtual Ethernet adapters
is in the range of 1-3 Gigabits per second , depending on the... [More]

"I need it yesterday" - quicker copies between AIX systems
"Go live or go home" If you need to get a lot of data from one AIX host to another, there's
more than one way to do it quickly. During a migration to a new system, you may do a database dump or archive and want to get the data available to the new LPAR within a short time frame. You can tweak the network settings improve your SAN configuration (just turn on the turbo switch) and assign more resources to ease the bottlenecks. Of course there's Live Partition Mobility (LPM) and various High
Availability options but they may not be... [More]
