IBM Corp. released an announcement letter this week that it will sell a Power7 version of the 595 — the big box — that will support DC power inputs.
The box, as usual, will support running AIX, IBM i and Linux. IBM will sell the box this year, saying the machine will be able to run up to 256 Power7 processor cores. Seeing as the Power7 chip can support up to eight cores per chip, compared to two for Power6, it looks like the Power7 big iron will have an architecture similar to the Power 595, just with Power7 instead of Power6 processors.
IBM unveiled the first of its Power7 servers earlier this week.
