- The obligatory 'Victoria Falls' post
- For those who don't know, Sun's new T2+ machines extend the T2's CMT capabilities across multiple units to produce 16 and 32 core SMP machines capable of handling 128 and 256 concurrent threads respectively. Sun blogger Denis Sheahan provides a good overview of the current dual...

- Solaris vs AIX: Price/performance
- IBM's newest AIX products feature the Power6, Sun's the UltraSPARC T2. It probably makes sense, therefore, to base a data center hardware cost comparison as much as possible on these two technologies. Comparable scaling is a key issue, but there's enough consistency about the benchmark results both...

- Almost two years ago I predicted that Sun's then pending T1 and subsequent T2 CMT machines would offer throughput levels roughly comparable to x86 machines producing the number of cycles you'd get multiplying Sun's CMT megahertz by their thread count -i.e that a T1 would produce roughly the throughput...
