IBM Reveals New Virtual Linux Environment
jenwren1010 writes to mention that IBM has just announced the new open beta version of their virtual Linux environment that allows users to run x86 Linux programs on POWER processor-based IBM System p servers. "Designed to reduce power, cooling and space by consolidating x86 Linux workloads on System p servers, it will eventually be released as the [rolls-off-the-tongue] 'IBM System p Application Virtual Environment (System p AVE).' With a 31.5% global revenue share during 2006, IBM hopes to build on System p UNIX success and extend firmly into the Linux marketplace. Considering there are almost 2,800 applications that already run natively on Linux on System p servers, the chances are good that it will succeed."
You can buy ONE rack and it has 64 processors in it. Each of those 64 processors can be sheared down to 1/10th of a CPU partition. That would be 640 servers in one rack. Granted, you'd never want to run that many LPARS on a system, but you could come close. You can also share all 64 of these processors and each of the LPARS can look like a SMP system by setting a VP of 2 or higher. Granted alot of this will need proper tuning, but you can do a lot with a pSeries and shove alot of hardware into one rack. Also, with Partition Load manager, it can very how much CPU each partition gets by the load it's getting. Say one of the LPARS gets nailed all of a sudden. If the partition is uncapped or not reached it's cap, it can automatically grab as much CPU as needed.
The pSeries machine CAN do what they describe.
