A software-based distributed caching system such as memcached is an important piece of today's largest Internet sites that support millions of concurrent users and deliver user-friendly response times. The distributed nature of memcached design transforms 1000s of servers into one large caching pool with gigabytes of memory per node. This blog entry explores single-instance memcached scalability for a few usage patterns.

Table below shows out-of-the-box (no custom OS rewrites or networking tuning required) performance with 10G networking hardware and one single-socket UltraSPARC T2-based server with 8 cores and 8 threads per core (64 threads on a chip). All runs are done with a single memcached instance and 40 worker threads so that about 3 cores (24 threads) are used for the critical networking stack that is also heavily parallelized. 40+24 threads is a nice balance for this …

Find out about Sun's new 4-chip UltraSPARC T2 Plus system direct from the source: Sun's engineers.

Sun today announced the 4-chip variant of its UltraSPARC T2 Plus system, the Sun SPARC Enterprise T5440. This new system is the big brother of the 2-chip Sun SPARC Enterprise T5140 and T5240 systems released in April 2008. Each UltraSPARC T2 Plus chip offers 8 hardware strands in each of 8 cores. With up to four UltraSPARC T2 Plus chips delivering a total of 32 cores and 256 hardware threads and up to 512Gbytes of memory in a compact 4U package, the T5440 raises the bar for server performance, price-performance, energy efficiency, and compactness. And with Logical Domains (LDoms) and Solaris Containers, the potential for server consolidation is compelling.

Standard configurations of the Sun SPARC Enterprise T5440 include 2- and 4-chip systems at 1.2 GHz, and a 4-chip system at 1.4 GHz. All of these configurations come with 8 cores per …

Sun engineers blog on the new multi-chip UltraSPARC T2 Plus systems

Today Sun is announcing new CMT-based systems, hard on the heels of the UltraSPARC T2 systems launched in October 2007 (the Sun SPARC Enterprise T5120 and T5220 systems). Whereas previous Sun CMT systems were based around a single-socket UltraSPARC T1 or T2 processor, the new systems incorporate two processors, doubling the number of cores and the number of hardware threads compared to UltraSPARC T2-based systems. Each UltraSPARC T2 Plus chip includes 8 hardware strands in each of 8 cores, so the Operating System sees a total of 128 CPUs. The new systems deliver an unprecedented amount of CPU capacity in a package this size, as evidenced by the very …

Sun engineers give the inside scoop on the new UltraSPARC T2 systems

[ Update Jan 2008: Sun SPARC Enterprise T5120 and T5220 servers were awarded Product of the Year 2007. ]

Sun launched the Chip-Level MultiThreading (CMT) era back in December 2005 with the release of the highly successful UltraSPARC T1 (Niagara) chip, featured in the Sun Fire T2000 and T1000 systems. With 8 cores, each with 4 hardware strands (or threads), these systems presented 32 CPUs and delivered an unprecedented amount of processing power in compact, eco-friendly packaging. The systems were referred to as CoolThreads servers because of their low power and cooling requirements.
