System architecture of Sun Sparc M3000 server

In SPARC Enterprise M3000 server the interconnect, processors, memory subsystem, and I/O subsystem work together to create a scalable, high-performance platform ready to address server consolidation needs.

The SPARC Enterprise M3000 server features two rack units (RU) and supports one processor chip and up to 64 GB of memory. 

The SPARC64 VII/VII+ (dual-core or quad-core) processor chip is mounted on the motherboard. 

The I/O subsystem of the SPARC Enterprise M3000 server features four short internal PCI Express slots, four internal disk drives, one internal DVD drive, and an external SAS port for attaching additional storage or tape device units. 

Two power supplies and two fan units power and cool the server.

System Interconnect:

The Jupiter system interconnect fosters high levels of performance, scalability, and reliability for SPARC Enterprise M 3000  server.

A single system controller within SPARC Enterprise M3000 servers provides point-to-point connections between CPU, memory, and I/O subsystems.

Processors:

SPARC Enterprise M3000 servers support SPARC64 VII+ processors.

 The SPARC64 VII/VII+ processor provides a quad-core implementation with a faster clock speed and a reduction in size using 65 nm fabrication.

Memory:

SPARC Enterprise M3000 servers support DDR-II DIMMs with 2-way memory interleave. 

The SPARC Enterprise M3000 server supports up to 64GB of memory using 8GB DIMM. ECC protection is implemented for data stored in main memory.

Memory patrol: 

Memory patrol periodically scans memory for errors. This proactive function prevents the use of faulty areas of memory and improving system reliability.

Memory Extended-ECC:

The memory Extended-ECC function of these servers provides single-bit error correction, supporting continuous processing despite events such as burst read errors that are sometimes caused by memory device failures

PCI Express:

The Sun Sparc Enterprise M 3000 has 4x PCI Express (x8, full-height, short) physical layer (PCI Express PHY) ASIC to manage the implementation of the PCI Express protocol.

Storage:

The Sun Sparc Enterprise M 3000 has up to four 600GB internal, 2.5in. SAS HDDs. 

Data on the internal disk can be further protected using the built-in HW RAID support.

Power  Supply:

The SPARC Enterprise M3000 server supports redundant power supplies. The power supplies support either AC or DC input

The Sparc Enterprise M3000 provides a powerful entry-level solution to mission critical computing, with the high-end benefits of virtualization, automation and the deployment flexibility of a UNIX application portfolio, usable in both A/C and D/C powered data centers.
