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 innovation seeks out specific - HP ProLiant SL6000 | HP Advanced Memory Error Detection Technology - Page 3
events or conditions can cause errors in individual memory cells, in multiple cells in different rows (a column failure), or in multiple cells in different columns (a row failure). For example, a defect in a word line or bit line can prevent part of a row or column from receiving a signal, resulting - HP ProLiant SL6000 | HP Advanced Memory Error Detection Technology - Page 4
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 average memory capacity per server has grown by more than 500%-from 5.6 GB to 33 GB per server across all HP ProLiant server lines - HP ProLiant SL6000 | 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 SL6000 | HP Advanced Memory Error Detection Technology - Page 6
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. For a list of specific servers - HP ProLiant SL6000 | HP Advanced Memory Error Detection Technology - Page 7
replaced good DIMMs at a cost of unnecessary downtime and repairs. In the ProLiant System ROM upgrade (version May 2011 or later), we have enhanced memory error protection with HP Advanced Memory Error Detection Technology. This innovation monitors several memory parameters and seeks out specific - HP ProLiant SL6000 | HP Advanced Memory Error Detection Technology - Page 8
