Advanced Memory Protection Technology
– delivers unsurpassed memory protection and server availability:
Advanced ECC Memory
ECC protection provides the ability to detect and correct single bit memory errors while Advanced ECC extends this
coverage to include protection against multiple simultaneous errors on a DIMM. Advanced ECC detects and
corrects 4bit memory errors that occur within a single DRAM chip on a DIMM. Advanced ECC algorithms work in
combination with industry standard ECC DIMMS.

Advanced Memory Protection Configurations
Online Spare Memory
Offers a higher level of memory protection than Advanced ECC alone. The system is configured with a spare bank
of memory. If the number of single-bit correctable errors on a bank exceeds the pre-defined error threshold, the
failing bank will fail over to the Online Spare bank without intervention or server interruption. The failed memory
can then be replaced at the user's convenience during a scheduled maintenance window.
Single-Board Mirrored Memory
Single-board mirrored memory provides a higher level of availability than Advanced ECC and Online Spare
Memory because it protects against multi-bit errors. Single-board Mirrored Memory uses a single memory board that
is configured with a mirrored/redundant set of memory. The system writes to both sets of memory, but reads from
one. If a memory bank has a multi-bit error or full DIMM failure, the system simply reads from the mirrored bank
instead. This process occurs without intervention or server interruption, and the failed DIMM can be replaced during
a regularly scheduled shutdown.
Hot Plug Mirrored Memory
Hot Plug Mirrored Memory is a fault-tolerant memory feature that provides a higher level of availability than
Advanced ECC, Online Spare Memory, or Single-Board Mirrored Memory because it protects against multi-bit errors
and does not require any server downtime to replace failed DIMMs. Hot Plug Mirrored Memory requires that two
memory boards be installed, one an exact mirror of the other, which run in parallel and provide protection against
multi-bit memory errors. When configured for Hot Plug Mirrored Memory, the system writes to both memory boards,
but reads from one. If a read error occurs, the system fails over to the redundant memory board. At that point the
memory board containing the failed DIMMs can be hot replaced. Once the failed DIMMs are replaced and the
memory board re-installed into the server, the system goes back to full mirrored status. All this occurs without
bringing the server down.

NOTE: NOTE:
NOTE:
Hot Plug Mirrored Memory and Dual-Board Online Spare Memory require the use of two memory cards. All
HP ProLiant ML570 G2 servers ship standard with a single memory board. The second memory board is optional
(P/N 236844-B21).
