Sun Microsystems introduced its Sun Constellation System — an open petascale computing environment that combines ultra-dense, high performance compute, networking, storage and software into an integrated general purpose system. The Sun Constellation System runs the Solaris Operating System (OS), Linux and Windows and is capable of scaling from departmental clusters to the largest supercomputer configurations. 
The Sun Constellation System comprises the following components:
- Sun Blade 6048 Modular System — An ultra dense blade server platform which supports SPARC, AMD Opteron and Intel Xeon processors and runs industry standard OS’es including Solaris and Linux.
- Sun Datacenter Switch 3456 — a single chassis switch designed for petascale, delivers 12x the capacity of the largest Infiniband switch available today, enables the Sun Constellation System to require 1/6 the number of cables of competitive systems and simplifies the design and management of high performance clusters by reducing the number of Infiniband switching elements by up to 300:1.
- High-throughput, high-density storage and high capacity tape archive in a unique end-to-end hierarchical storage solution with automated and seamless transfer supporting optimal placement of data.
Sun also introduced its StorageTek 5800 System, which the company describes as a new category of storage system leveraging open source and designed for large-scale storage of fixed data.
