Re: Facts about Power
[...AC because I consult on all vendors, all O/S's...]
Good post and worthy of a detailed read.
I have to mention some of the points you bring up
Firstly, the RAS features on a Power server such as this really don't vary much from an equivalent x86 vendor. the CPU is different, but the memory DIMMs have the same MTBF, as do the power supplies, motherboards, etc. When I see x86 vendors now discussing MTBFs on latest generation hardware of 8-11 years, this reliability question has largely gone away.
Almost all customers are building in RAS using software anyway, such as VMware, Oracle RAC, etc. which is why the market for Unix continues to decline.
Your example of a customer running a mixed shop with just 2 FTE's on the Power side is irrelevant. I have a customer with over 600 x86 servers and just two FTEs maintaining the install.
You only need two x86 servers for a cluster too - the same as Power - so what's your point?
your 4-to-1 ratio is unrealistic - even the article states that you are getting about 20% more performance from a Power system - and that's only if your application allows you to run the server at 100%, otherwise it's unusable.
The TCA and TCO will never be lowest on the Power side. If that were the case, everyone would be migrating there - but they are not. I've had countless conversations and assisted with migrations from proprietary to industry standard over the last 5 years. Not one customer I've worked with has migrated from industry standard to proprietary because the numbers just don't work. The lowest cost model is always going to be industry standard x86 platform.
I get that you have a particular point of view and work for a company that values its worth through its relationship with IBM. IBM's strengths continue to be in its software, services and channel relationships - hardware is largely a vehicle for IBM to sell software and services.
This product line was IBM's attempt to differentiate itself in a market where it is losing ground across the board in hardware: its x86 share is declining, Unix is going the same way as the mainframe and the iSeries is slowly sunsetting. IBM's storage lines are struggling against the big vendors too, if IDC is to be believed. The product line is a worthy try and will be interesting to IBM shops, but the rest of the IT industry will take a pass.
