Portrix debugs live VoIP service using DTrace

Hamburg-based Portrix is providing and hosting the telephony software SmartDialer for a large German call center. SmartDialer is based on a Solaris port of the open-source Asterisk package. The application performs very well on the Sun Fire T2000 chosen for deployment --Solaris outperforms Linux at running Asterisk and Sparc CMT processors are ideally suited for highly multithreaded applications like Asterisk. In production however, SmartDialer experienced some stability issues after a couple of days of uptime, and a very high system time --up to 60%-- was seen on the machine. As a consequence, the quality of the VoIP connection dropped to the point that a reboot of the server was necessary. Oddly, restarting the application alone did not help.

As a member of the Sun Startup Essentials program, Portrix called upon Sun for additional guidance on the issue; this is how our ISV Engineering team got involved in this debugging effort. Unfortunately, there was no adequate load generator for the Portrix VoIP applications --it would have enabled us to reproduce the issue on a separate server-- and all analysis had to be done on the live production system. Quite a scary thought as we know that traditional debugging/profiling tools attach to the running process and momentarily stop it, as part of the procedure. In the best case, that means the call is interrupted for a second or two; in the worst case, the call is dropped and this was unacceptable to the customer.

Enters DTrace. DTrace is a comprehensive dynamic tracing framework for…

Coolthreads & Containers come to Comverse

"We evaluated the Sun Fire T1000 server for our product needs in Value-Added Services. Our benchmark results show significant overall performance gains over existing Sun servers. We are pleased with these results and will continue work with Sun to deploy CMT technologies in our next generation systems."
Alexander Katz, Director, Platforms Product Management, Comverse

At the time Sun released its first server line based on the revolutionary Chip Multi-Threading (CMT) a.k.a. CoolThreads processor design, Comverse was a long customer of traditional UltraSPARC systems from Sun. Over the years, they had learned to love the predictable performance of such a RISC processor pipeline, the reliability of Sun Netra servers (NEBS-certified for demanding Telco environments) and the guaranteed upward binary compatibility of the Solaris operating system. The latest supported configuration then, for the component of Comverse Messaging Alexander Katz was referring to, was 210/240-class UltraSparc3i-based systems running Solaris 9, and a typical customer deployment would include several of these servers.

In a permanent effort to strengthen customer loyalty and improve the price/performance of its solutions, Comverse challenged Sun Microsystems and our ISV Engineering group to gain an order of magnitude in price/performance for Messaging. The Telco industry had started to adopt Linux then so Lintel looked here like the default alternative and safe choice. Such a choice however was not leveraging the trust the customers had built in SPARC, the up-front cost of migrating from Solaris to Linux was high, and a me-too solution was not giving any competitive advantage to Comverse. So we introduced the Sun T-series systems and their CMT design, running Solaris 10...
