IBM recently introduced Power7 blade servers to go with the Power6 and x86 blades already available. The Power7 blades come in 4-core, 8-core, or a “double-wide” 16-core configuration (with two 8-core servers tied together). However, the 4-core configuration – with four disabled cores – cannot be upgraded to eight active cores directly (the four extra cores are permanently disabled). The 16-core configuration is two Power7 blades combined together.

Also introduced was AIX 6 Express, a new (and lower cost) version of AIX for small business.

I’ve always been partial to Power since Apple started using it; it was sad to see Apple stop using the PowerPC.

AIX has never struck me as a well-regarded environment, but now IBM has made it more affordable for more folks; we’ll see how this goes. The AIX admins I knew were frequently complaining about the clustering environment (although HP ServiceGuard has lots of interesting problems too). Last time I used AIX, the printing environment was very odd, like the rest of it.

However, no UNIX can be all bad… right?
