Sun Memory (m3000,m4000,m5000,m8000,m9000 Servers)

The memory subsystem of SPARC Enterprise M3000, M4000, M5000, M8000, and M9000 servers increases the scalability and throughput of these systems. In fact, the SPARC Enterprise M9000 server accommodates up to 4 TB of memory. SPARC Enterprise M3000 servers support DDR-II DIMMs with 2-way memory interleave. SPARC Enterprise M4000, M5000, M8000, and M9000 servers use
DDR-II DIMM technology with 8-way memory interleave to enhance system performance. While multiple DIMM sizes are not supported within a single bank, DIMM capacities can vary across system boards. Available DIMM sizes include 1 GB, 2 GB, 4 GB, and 8 GB densities.

Memory
Capacity Beyond performance, the memory subsystem of SPARC Enterprise M3000, M4000, M5000, M8000, and M9000 servers are built with reliability in mind. ECC protection is implemented for data stored in main memory, and the following advanced features foster early diagnosis and fault isolation that
preserve system integrity and raise application availability.
Memory patrol Memory patrol periodically scans memory for errors. This proactive function prevents the use of faulty areas of memory before they can cause system or application errors, 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. This feature is similar to IBMs Chipkill technology.
Memory Mirroring SPARC Enterprise M4000, M5000, M8000, and M9000 servers support memory mirroring capabilities.
Memory mirroring is an optional, high-availability feature appropriate for execution of applications with the most stringent availability requirements. When memory mirroring mode is enabled on SPARC Enterprise M4000, M5000, M8000, and M9000 servers, the memory subsystem duplicates the data on write and compares the data on read to each side of the memory mirror. In the event that errors occur at the bus or DIMM level, normal data processing continues through the other memory bus and alternate DIMM set. In SPARC Enterprise M4000 and M5000 servers, memory is mirrored within the same memory module, using the common memory address controller (MAC) Application Specific Integrated Circuit (ASIC).
In conclusion:
To support demands for greater levels of scalability, reliability, and manageability in the datacenter, infrastructures need to provide ever-increasing performance and capacity while becoming simpler to deploy, adjust, and manage. The SPARC Enterprise M3000, M4000, M5000, M8000, and M9000
servers outfitted with SPARC64 VI and SPARC VII/VII+ processors, large memory capacity, an inherently reliable architecture, and an eXtended system control facility deliver new levels of power, availability, and ease-of-use to enterprises. The sophisticated resource control provided by Dynamic
Domains, eXtended system boards, and Dynamic Reconfiguration further increase the value of these servers by helping enterprises to optimize the use of these hardware assets. By deploying fast, scalable SPARC Enterprise M3000, M4000, M5000, M8000, and M9000 servers from Oracle, organizations
gain extraordinary power and flexibility a strategic asset in the quest to gain a competitive business advantage.
