The SPARC Enterprise series is a range of UNIX server computers based on the SPARC V9 architecture. It was co-developed by Sun Microsystems and Fujitsu, and introduced in 2007. They were marketed and sold by Sun Microsystems (later Oracle Corporation, after their acquisition of Sun), Fujitsu, and Fujitsu Siemens Computers under the common brand of "SPARC Enterprise", superseding Sun's Sun Fire and Fujitsu's PRIMEPOWER server product lines.

SPARC64 processor based models (M-series)
- M3000 - 1 processor socket, 2U rack-mount
- M4000 - Up to 4 processor sockets, 6U rack-mount
- M5000 - Up to 8 processor sockets, 10U rack-mount
- M8000 - Up to 16 processor sockets, one data center rack
- M9000 - Up to 64 processor sockets, one or two data center racks
The SPARC64 VI is a dual-core processor, with each core featuring two-way vertical multi-threading (VMT). A M9000 server configured with the maximum number of processors supports running 256 concurrent threads. VMT is a coarse-grained multi-threading implementation. Each core in the SPARC64 VI can handle two strands or threads. VMT switches execution from one strand to the other on the basis of events. To execute instructions from another thread, the pipeline must be saved/flushed and switched to the registers for the other thread. These events include L2 cache misses, a hardware timer exception, interrupts, or some multi-threading-related control instructions. This is also called Switch On Event (SOE) threading.
In 2008, Fujitsu released the SPARC64 VII, a quad-core processor, with each core featuring two-way simultaneous multi-threading. Existing M-class servers will be able to upgrade to the SPARC64 VII processors in the field.
In 2010, Fujitsu released the SPARC64 VII+, running at higher frequency and with a larger L2 cache than its predecessor. A SPARC64 VII or SPARC64 VII+ processor module includes four physical cores, where each core can execute two threads. Each physical core is able to run both threads simultaneously. With SMT, there is no context-switch time and the two threads share the instruction pipeline smoothly. When both are ready to run, they alternate cycles for superscalar instruction issue, and share the functional units according to need.
An important capability of the M-Series is the ability to mix processor generations and clock speeds in the same system and domain. All M-Series servers can have both SPARC64 VI and SPARC64 VII CPUs installed and they will run at their native speeds, with no clocking down to the slowest CPU.
On April 17, 2007, a Sun SPARC Enterprise M9000 achieved 1.032 TFLOPS on the LINPACK benchmark, making it the fastest single system supercomputer at that time.
As of February 19, 2009, the SPARC Enterprise M8000 holds the 64-thread world performance records on the SPEC OMP2001 benchmark, both for medium and for large
UltraSPARC T processor based models (T-series)
- T1000 - 1 processor socket, 1U rack-mount
- T2000 - 1 processor socket, 2U rack-mount
In October 2007, Sun added the UltraSPARC T2-based servers to the SPARC Enterprise line:
- T5120 - 1 processor socket, 1U rack-mount
- T5220 - 1 processor socket, 2U rack-mount
In April 2008, Sun added the UltraSPARC T2 Plus-based servers to the SPARC Enterprise line:
- T5140 - 2 processor sockets, 1U rack-mount
- T5240 - 2 processor sockets, 2U rack-mount
In October 2008, Sun released the 4-way SMP UltraSPARC T2 Plus-based server:
- T5440 - 4 processor sockets, 4U rack-mount
Partitioning and virtualization
The UltraSPARC T1, UltraSPARC T2/T2+ models partition the system using Logical Domains.
Both M-series and T-series models support Solaris Containers, which supports a maximum of 8191 non-global zones in each Dynamic Domain or Logical Domain.
