Oracle Delivers On SPARC Promises

Richard Fichera


When I returned to Forrester in mid-2010, one of the first blog posts I wrote was about Oracle’s new roadmap for SPARC and Solaris, catalyzed by numerous client inquiries and other interactions in which Oracle’s real level of commitment to future SPARC hardware was the topic of discussion. In most cases I could describe the customer mood as skeptical at best, and panicked and committed to migration off of SPARC and Solaris at worst. Nonetheless, after some time spent with Oracle management, I expressed my improved confidence in the new hardware team that Oracle had assembled and their new roadmap for SPARC processors after the successive debacles of the UltraSPARC-5 and Rock processors under Sun’s stewardship.

Two and a half years later, it is obvious that Oracle has delivered on its commitments regarding SPARC and is continuing its investments in SPARC CPU and system design as well as its Solaris OS technology. The latest evolution of SPARC technology, the SPARC T5 and the soon-to-be-announced M5, continue the evolution and design practices set forth by Oracle’s Rick Hetherington in 2010 — incremental evolution of a common set of SPARC cores, differentiation by variation of core count, threads and cache as opposed to fundamental architecture, and a reliable multi-year performance progression of cores and system scalability.

UNIX – Dead Or Alive?

Richard Fichera

There has been a lot of ill-considered press coverage about the “death” of UNIX and coverage of the wholesale migration of UNIX workloads to LINUX, some of which (the latter, not the former) I have contributed to. But to set the record straight, the extinction of UNIX is not going to happen in our lifetime.

While UNIX revenues are not growing at any major clip, it appears as if they have actually had a slight uptick over the past year, probably due to a surge by IBM, and seem to be nicely stuck around the $18 - 20B level annual range. But what is important is the “why,” not the exact dollar figure.

UNIX on proprietary RISC architectures will stay around for several reasons that primarily revolve around their being the only close alternative to mainframes in regards to specific high-end operational characteristics:

  • Performance – If you need the biggest single-system SMP OS image, UNIX is still the only realistic commercial alternative other than mainframes.
  • Isolated bulletproof partitionability – If you want to run workload on dynamically scalable and electrically isolated partitions with the option to move workloads between them while running, then UNIX is your answer.
  • Near-ultimate availability – If you are looking for the highest levels of reliability and availability ex mainframes and custom FT systems, UNIX is the answer. It still possesses slight availability advantages, especially if you factor in the more robust online maintenance capabilities of the leading UNIX OS variants.

Oracle Open World Part 3 - Oracle’s “Engineered Systems”: Astute Integration Or Inspired Folly?

Richard Fichera

OK, out of respect for your time, now that I’ve caught you with a title that promises some drama I’ll cut to the chase and tell you that I definitely lean toward the former. Having spent a couple of days here at Oracle Open World poking around the various flavors of Engineered Systems, including the established Exadata and Exalogic along with the new SPARC Super Cluster (all of a week old) and the newly announced Exalytic system for big data analytics, I am pretty convinced that they represent an intelligent and modular set of optimized platforms for specific workloads. In addition to being modular, they give me the strong impression of a “composable” architecture – the various elements of processing nodes, Oracle storage nodes, ZFS file nodes and other components can clearly be recombined over time as customer requirements dictate, either as standard products or as custom configurations.

Oracle Delivers On SPARC Promises With New T4 Processors And Systems

Richard Fichera

Background – Promises And Potential

Last year I wrote about Oracle’s new plans for SPARC, anchored by a new line of SPARC CPUs engineered in conjunction with Fujitsu (Does SPARC have a Future?), and commented that the first deliveries of this new technology would probably be in early 2012, and until we saw this tangible evidence of Oracle’s actual execution of this road map we could not predict with any confidence the future viability of SPARC.

The T4 CPU

Fast forward a year and Oracle has delivered the first of the new CPUs, ahead of schedule and with impressive gains in performance that make it look like SPARC will remain a viable platform for years. Specifically, Oracle has introduced the T4 CPU and systems based on them. The T4, an evolution of Oracle’s highly threaded T-Series architecture, is implemented with an entirely new core that will form the basis, with variations in number of threads versus cores and cache designs, of the future M and T series systems. The M series will have fewer threads and more performance per thread, while the T CPUs will, like their predecessors, emphasize throughput for highly threaded workloads. The new T4 will have 8 cores, and each core will have 8 threads. While the T4 emphasizes highly threaded workload performance, it is important to note that Oracles has radically improved single-thread performance over its predecessors, with Oracle claiming performance per thread improvements of 5X over its predecessors, greatly improving its utility as a CPU to power less thread-intensive workloads as well.
