The Sun SPARC Enterprise T5120 server was put to the test by InfoWorld's Paul Venezia, who attributes the performance of this server to the UltraSPARC T2 processor, a single CPU running four, six or eight cores. Among the improvements in the UltraSPARC T2 are increased bandwidth to mainline I/O, decreased latency, core-specific memory controllers, FPU, cryptographic accelerator, and 4MB L2 cache, plus x8 PCle and two 10G Ethernet controllers, all of which reside on a single CPU die.
The Sun Netra T5220 (DC version) is now available. This high-efficiency, ruggedized rack server platform is based on the second generation of the Chip Multi-threaded Technology (CMT) UltraSPARC T2 processor. The Netra T5220 server offers extreme reliability and high throughput, at the same time offering processor core, memory and I/O densities to enable expansion and flexibility with a compact 2U form factor. The Netra T5220 will be the ideal platform for virtualization. The Sun Netra T5220 (AC version) is coming in April 2008.
There's a good more than meets the eye in the claims IBM is making for its new z10 mainframe, for which Big Blue claims a 30 to 1 ability to consolidate software licenses, among other things. Sun blogger Jeff Savit asserts further that this claim is based on 760 X2100 cores to 26 z10. The 760 to 26 is based on 3845 RPEs at 10 percent = 384.5 RPEs, which is approximately equivalent to the number of z10 RPEs at 90 percent when you use 20 RPEs equal to 1 MIP where MIPS are based on the LSPR curve for the z10. Got that? Well, read on, in the Sun blog, which points out that these measures were not taken under load, the only true measure of system performance.
There's something new in the wind for the Sun Netra T2000 eight core (8 GB) RoHS compliant server, which is being retired from the Sun product list and replaced by a new standard configuration based on a 1 GB DIMM rather than the 512MB DIMM, which is slated for EOL on September 5, 2008. Users of the Sun Netra product line will find in the newly configured Sun Netra T2000 server increased throughput with both footprint and power savings in a solution that meets the increasing demands of the network infrastructure using Sun's Chip Multithreaded (CMT) processor architecture.
You can now get Sun SPARC Enterprise M4000 and M5000 servers with 8GB total memory which includes two half populated memory boards using 1GB DIMMs. Customers also have the flexibility of purchasing a 4GB memory module (4 x 1GB DIMMs) and 4GB memory expansion kit (4 x 1GB DIMMs) as options for a lower priced system configuration.
