Oracle License Change: Add SPARC T4

Oracle License Change: Add SPARC T4

Abstract

Oracle licenses it's RDBMS by several factors, typically the Standard License (by socket) and an Enterprise License (by core scaling factor.) Occasionally, Oracle will change the core scaling factor, resulting in discounting or liability for the consumer.

The Platform

The SPARC CPU from Oracle is an implementation of the SPARC V9 open specification. There have been several series of chips based upon this implementation: T1, T2, T2+, and T3. The T1 & T2 are both single socket implementations, while the T2+ and T3 are a multi-socket implementation. Oracle has released on their roadmap that the SPARC T4 processor will be coming out shortly.

The Addition

The SPARC T4 has been added to the Oracle RDBMS "Processor-Core Factor Table".

Factor Vendor/Processor
0.25 SUN UltraSPARC T1 <1.4GHz
0.25 Oracle SPARC T3
0.50 SUN UltraSPARC T1 1.4GHz
0.50 SUN UltraSPARC T2+ Multicore
0.50 Fujitsu SPARC VII+
0.50 Oracle SPARC T4
0.75 SUN UltraSPARC IV, IV+, or earlier
0.75 Fujitsu SPARC64 VI, VII
0.75 SUN UltraSPARC T2


Note, Green is new. Oracle has added the T4 processor with a core factor of 0.50.

Impacts to Network Management Infrastructure

It appears that Oracle will be releasing SPARC T4 into production. Purchasing should be watched very closely during this transition period.

If there is the need for increased thread performance, the 8 core T4 may be leveraged instead of the 16 core T3, with no impact to Oracle licensing when databases require an RDBMS.

The UltraSPARC IV+ 21.GHz processors had some of the best single-threaded performance characteristics of any SPARC processor ever produced (albeit, the throughput pales in comparison to any of the newer generation of multicore SPARC systems.)

The Oracle SPARC T4 finally looks like a good candidate to replace those old SUN UltraSPARC IV+ systems, which are so highly cherished for their single thread performance. There is probably no better Network Managment platform to consider at this point in time.
