Infovista VistaInsight for Networks shows 3.7x performance on Oracle

System management vendor InfoVista markets the VistaInsight for Networks® application to enable telco operators, service providers and large enterprises effectively meet performance and service level agreements of converged and next-generation communication networks. As part of our on-going technology partnership, InfoVista and Oracle ISV Engineering together ran a performance test campaign of VistaInsight for Networks® over Oracle Solaris and Sun CMT hardware. The two companies shared many common objectives when starting this project.

The most obvious was to improve the scalability and performance of VistaInsight for Networks® over Oracle's SPARC T-Series systems and thereby provide customers with a better price/performance ratio and a better ROI. From the onset, virtualization was considered a promising technology to improve scalability, thus testing VistaInsight for Networks® in the context of Oracle Solaris Zones was also a major milestone.

Second, InfoVista was interested in setting new limits in terms of the workload that its application can sustain, in response to the evolving needs of its customers.

Lastly, as the first improvements on computing scalability were delivered, it became obvious that the storage was the next critical component for the performance of the entire solution. A decision was then made to test the Oracle Solaris ZFS file system, the Sun ZFS Storage Appliance, and the SSD technology from Oracle to move to the next level of performance.

The result of this performance test campaign is a new Reference Architecture whitepaper that provides detailed information about the configuration tested, the tests executed and the results obtained. It clearly shows that VistaInsight for Networks® takes full advantage of the server, storage and virtualization technology provided by Oracle. By leveraging the Oracle Solaris Zones, Oracle Solaris ZFS, SSD and Sun ZFS Appliance storage, Infovista increased the throughput performance by more than 370%, meeting the highest expectations in terms of workload and performance while maintaining the cost in a very attractive range.

Perforce runs best on ZFS

Perforce is a commercial source code management software available on many platforms including Solaris Sparc and Solaris x86. As one of our ISV partner experienced last year, the storage subsystem is likely the performance bottleneck of a Perforce Server installation. With entry-level systems featuring a minimum of 4 CPU cores, 4GB memory and dual GigE network nowadays --I am looking e.g. at the base configuration of the Sun Fire X2250 server--, CPU, memory and network are no longer bottlenecks. Unless you run Windows and are subject to the 2GB limit of addressable memory in Windows --Solaris will, by the way, happily let 32-bit applications allocate most of the theoretical 4GB of addressable memory, and you can go beyond that with the 64-bit Perforce Solaris binaries.

So our partner was experiencing poor performance and blocking situations under high load (280 users, 16M files, 15 server instances) with Perforce Server 2006.2 when running off a Sparc V440 server, Solaris 10 and UFS filesystem --with logging enabled. Benchmark results at the 2003 Perforce User Conference had already pointed out the low performance of UFS with Perforce, where synchronous directory updates are a key factor of performance. Linux performs better because it executes directory updates asynchronously --at the risk of data loss, of course. Our partner rather wanted to run off a more reliable Solaris Sparc server --the source code repository and management system is the number one mission-critical application in a software house--, tuned the kernel parameter segmap_percent to 80 but that yields very limited gains in Solaris 10. At that point, we offered to test ZFS, the novel filesystem introduced in Solaris 10.

We benchmarked Perforce Server (P4D) 2007.2 on a Sun Fire X4200 server and …
