. This lets the administrator schedule server maintenance to replace a DIMM that may fail, avoiding unexpected interruption of business operations. In the ProLiant System ROM upgrade (version May 2011 or later), we have enhanced protection with HP Advanced Memory Error Detection Technology. This - HP ProLiant DL380p | HP Advanced Memory Error Detection Technology - Page 3
of times per second. The operating voltage of the DIMM determines the level of the electrical charge. As shown in the read operation Figure 2, the memory controller sends the address signals-bank, row, and column-that specify the location of the target DRAM cell. In the designated bank, the row - HP ProLiant DL380p | HP Advanced Memory Error Detection Technology - Page 4
for higher DIMM storage capacity. Server memory capacity is increasing The growth of high-performance computing (HPC) and virtualized IT environments is driving operating systems to address more memory. This is causing manufacturers to expand the memory capacity of servers. In the last 5 years, the - HP ProLiant DL380p | HP Advanced Memory Error Detection Technology - Page 5
the demands of HPC and virtualization. For example, an HP ProLiant DL580 G7 server fully populated with 32 GB DIMMs contains 2 TB of system memory, which translates to 18 trillion memory cells. DRAM technology is changing Memory manufacturers increase DIMM storage capacity by decreasing DRAM feature - HP ProLiant DL380p | HP Advanced Memory Error Detection Technology - Page 6
with a non-recoverable memory error. HP ProLiant servers supported HP Advanced Memory Error Detection Technology is introduced in the System ROM upgrade (May 2011 or later) for certain Intel Xeon-based ProLiant G6 and G7 platforms and for certain AMD Opteron-based ProLiant G7 platforms.
