Re: Reduce licensing costs - disable cores?

Hi Robert
just wondering - have you considered the SPARC VII alternatives in the
M-series servers ?

They are quad-core CPUs which boils down to a more granular 2 "processor"
license per CPU.

By all accounts they are better suited to single-threaded performance, vs
the T-series (T4, T3 etc) CPUs. That could be a pro or con I guess,
depending on your environment.  We're doing a similar evaluation and are
leaning towards M-series and SPARC VII for this reason.

HTH,
Jeff
