Oracle today released the SPARC T3 processor and four new systems ranging from the SPARC T3-1 with 1 CPU, 16 cores, 64 threads to the SPARC T3-4 with 4 CPUs 64 cores, 512 threads. No surprises, it the 16 core successor to the UltraSPARC T2(+) which we have been expecting since at least year, enhancements to the built-in crypto support and more cores but the same frequency and single-thread performance.
The minimal supported release of Solaris 10 is 10/09 which is good, I was afraid they would require the latest 9/10 update.
The minimal supported release seems to have changed in all documentation change to "Solaris 10 09/10", by wihch i assume they mean 9/10. This new way of writing the release name with a leading zero in the month part of the name makes it even harder to decode the name than just having two releaes named 9/10 and 10/09 and it does not match the name in /etc/release:
Oracle Solaris 10 9/10 s10s_u9wos_14a SPARC
