Standard Features
Availability • 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: Hot Plug Mirrored Memory and Dual-Board Online Spare Memory require the use of two memory
cards. All DL580 G2 servers ship standard with a single memory board. The second memory
board is optional (P/N 203320-B21).
Note: All Advanced Memory Protection modes are user configurable through the ROM-Based Setup
Utility (RBSU) and viewable through Insight Manager 7 (CIM 7) and the Integrated Management
Log (IML.).
