Additional Feature Information
Chip-Multithreaded Processor and Memory
Technology
The UltraSPARC T2 Plus multicore, multithreaded, processor is the basis of theSPARC
Enterprise T5440 server. Up to four UltraSPARC T2 Plus processors can be installed.
The UltraSPARC T2 Plus processor is based on chip-multithreading (CMT) technology that
is optimized for highly threaded transactional processing. The UltraSPARC T2 Plus
processor improves throughput while using less power and dissipating less heat than
conventional processor designs.
Depending on the model purchased, each processor chip has six or eight UltraSPARC cores.
Each core has two integer pipelines, each pipeline runs four threads, for a total of eight
threads per core.
Additional processor components, such as L1 cache, L2 cache, memory access crossbar,
memory controllers, and the I/O interface have been carefully tuned for optimal performance.
Enhancements
The SPARC Enterprise T5440 server expands the CoolThreads family to include dual socket
systems. It delivers extremely high compute density with up to 256 threads in 4 rack units.
The SPARC Enterprise T5440 server provides advanced power management through the
UltraSPARC T2 Plus power management features that work at both the core and the memory
levels of the processor, including the ability to reduce instruction issue rates, parking of idle
threads and cores, and the ability to turn off clocks in both cores and memory to reduce
power consumption.
In addition, this server offers the following features:
High memory density with up to 256 GB in four rack units.
High internal storage capacity with over 500 Gbytes available.
* PCIe and PCI-X specifications described in this table list the physical requirements for PCI cards. Additional support ca-
pabilities must also be provided (such as device drivers) for a PCI card to function in the server. Refer to the specifications
and documentation for a given PCI card to determine if the required drivers are provided that enable the card to function in
this server.
