It's ES7000 II, in 2008 I tried to get a UNIX to Linux/Windows program launched and got laughed at by the powers in place at the time. They will probably dust off the IBM Mainframe Migration program next. Better hope Clearpath had a good quarter.
The biggest challenge I recall on UNIX to Windows migration was the lack of mainframe-like management tools for the ES7000. We couldn't get MSFT to invest in true Datacenter differentiation. Scale out was a different story.
For once, I would like to see a press release with a customer reference proving the claims.
The server gig is over. Rumors are that IBM is looking for a buyer like they did for PCs.
