07 Sep 2014 Two Ways IBM Has Over-promised and Under-delivered with POWER8 to Date [38143]
By Kelvin Gee

Kelvin writes, "IBM launched its first POWER8 systems in April 2014. So now that the dust has settled and the first systems have started shipping, let's take stock of what IBM actually delivered with POWER8.

IBM has shown on previous roadmaps that it has a 3-year release cycle for new POWER generations. Following that cadence, IBM clearly missed its POWER8 release by more than a year, given that POWER7 systems started shipping the Spring of 2010 and the first POWER8 systems started shipping June 2014..."

06 Feb 2014 SPARC T5-2 server shatters another world record! [34773]
By Claudiac Caramelli

Claudiac writes, "Since their introduction last year, Oracle's T5 servers have topped performance metrics across enterprise workloads. Now SPARC T5 server has just shattered another world record...

In that test, the SPARC T5-2 server:

Showed the best performance per socket for a single system in the application tier Demonstrated 1.5 times higher performance compared to Oracle's 2-socket Sun Server X4-2 systems, running Intel's E5-2600 v2 series processor (Ivy Bridge) Delivered 29% better performance and 20% better price performance compared to a two-socket IBM PowerLinux POWER7+ processor-based server

01 Feb 2014 SPARC T5-2 Server Shatters Another World Record and Gets Single-Processor Configuration [34673]
SPARC T5-2 server is now offered in a single-processor configuration

Since their introduction last year, Oracle's T5 servers have topped performance metrics across enterprise workloads. The SPARC T5 server has just shattered another world record (see the latest SPECjEnterprise2010 2-socket benchmark result). In that test, the SPARC T5-2 server:

  • Showed the best performance per socket for a single system in the application tier
  • Demonstrated 1.5 times higher performance compared to Oracle's 2-socket Sun Server X4-2 systems, running Intel's E5-2600 v2 series processor (Ivy Bridge)
  • Delivered 29% better performance (1) and 20% better price performance compared to a two-socket IBM PowerLinux POWER7+ processor-based server

Another piece of good news is that Oracle is announcing that the SPARC T5-2 server is now offered in a single-processor configuration, making it easier to adopt Oracle's latest technology

23 Jan 2014 SPARC T5-2 Delivers World Record 2-Socket Application Server [34573]
for SPECjEnterprise2010 Benchmark

Oracle's SPARC T5-2 servers have set the world record for the SPECjEnterprise2010 benchmark using two-socket application servers with a result of 17,033.54 SPECjEnterprise2010 EjOPS. The result used two SPARC T5-2 servers, one server for the application tier and the other server for the database tier.

The SPARC T5-2 server delivered 29% more performance compared to the 2-socket IBM PowerLinux server result of 13,161.07 SPECjEnterprise2010 EjOPS.

The two SPARC T5-2 servers have 1.2x better price performance than the two IBM PowerLinux 7R2 POWER7+ processor-based servers (based on hardware plus software configuration costs for both tiers). The price performance of the SPARC T5-2 server is $35.99 compared to the IBM PowerLinux 7R2 at $44.75.

The SPARC T5-2 server demonstrated 1.5x more performance compared to Oracle's x86-based 2-socket Sun Server X4-2 system (Ivy Bridge) result of 11,259.88 SPECjEnterprise2010 EjOPS. Oracle holds the top x86 2-socket application server SPECjEnterprise2010 result.

This SPARC T5-2 server result represents the best performance per socket for a single system in the application tier of 8,516.77 SPECjEnterprise2010 EjOPS per socket.

The application server used Oracle Fusion Middleware components including the Oracle WebLogic 12.1 application server and Java HotSpot(TM) 64-Bit Server VM on Solaris, version 1.7.0_45. The database server was configured with Oracle Database 12c Release 1.

This result demonstrated less than 1 second average response times for all SPECjEnterprise2010 transactions and represents Jave EE 5.0 transactions generated by 139,000 users.

01 Oct 2013 SPARC T5 Encryption Performance Tops Intel E5-2600 v2 Processor [33007]
Cryptography benchmark suite developed by Oracle

The cryptography benchmark suite was developed by Oracle to measure security performance on important AES security modes. Oracle's SPARC T5 processor with it security software in silicon is faster than x86 servers that have the AES-NI instructions. In this test, the performance of on-processor encryption operations is measured (32 KB encryptions). Multiple threads are used to measure each processors maximum throughput. The SPARC T5-8 shows dramatically faster encryption.

A SPARC T5 processor running Oracle Solaris 11.1 is 2.7 times faster executing AES-CFB 256-bit key encryption (in cache) than the Intel E5-2697 v2 processor (with AES-NI) running Oracle Linux 6.3. AES-CFB encryption is used by Oracle Database for Transparent Data Encryption (TDE) which provides security for database storage.

On the AES-CFB 128-bit key encryption, the SPARC T5 processor is 2.5 times faster than the Intel E5-2697 v2 processor (with AES-NI) running Oracle Linux 6.3 for in-cache encryption. AES-CFB mode is used by Oracle Database for Transparent Data Encryption (TDE) which provides security for database storage.

The IBM POWER7+ has three hardware security units for 8-core processors, but IBM has not publicly shown any measured performance results on AES-CFB or other encryption modes.
