There is one thing you can count on when it comes to technology: it gets better over time. Processors get faster, systems use less energy while performing much better, and the cost per unit of computation drops.
Sometimes these improvements are so radical that customers can exploit them to significantly reduce the size and cost of their IT environment. Such is the case with the Fujitsu SPARC M12.
Let’s look at how Fujitsu SPARC M12 stacks up against older SPARC systems on a performance basis. For comparative performance figures, we’re using SPEC benchmark scores that can be found at www.spec.org.
The numbers in the second column are the SPEC scores for each of the respective systems when measured on a per-core basis. The ‘Consolidation Ratio’ column is simply the SPEC score for the Fujitsu SPARC M12-2S (67.92) divided by the SPEC score of the respective system as shown in column two.
In other words, if you look at the Sun SPARC Enterprise T5440 in the first row, you’ll see that the consolidation ratio is 6.43. This means that a single core in the Fujitsu SPARC M12-2S provides the same performance as 6.43 cores of the SPARC Enterprise T5440.
With this in mind, you could, for example, comfortably consolidate a 32 core T5440 system onto only five activated cores in a Fujitsu SPARC M12-2S system.
Likewise, an 8-processor, 32 core Oracle SPARC Enterprise M5000 system could also be consolidated onto just five cores on a Fujitsu SPARC M12-2S system, due to the 6.94 consolidation ratio per core between the two servers.
When you talk about consolidation ratios of over 6:1, it has large implications for the data center. Fewer cores in use mean lower software licensing costs – sometimes drastically lower. Another benefit is reduced software maintenance costs, which are based on total annual licensing costs.
The same applies for hardware maintenance costs, which are based on the list prices of the systems when purchased. Newer systems, like the Fujitsu SPARC M12, provide much more performance (as you can see above) in a single system than older servers.
In upcoming blogs, we’re going to take a closer look at these costs, put together some models, and prove out the cost justification for consolidating older Solaris SPARC workloads onto a new Fujitsu SPARC M12 system.
