1 Memory This guide explains the procedures associated with the memory system in your HP ProLiant ML530 Generation 2 server.
Memory For more information specific to Advanced Memory Protection, refer to the following resources: • The white paper on Advanced Memory Protection on the HP website: www.hp.
Memory CAUTION: Electrostatic discharge can damage electronic components. Be sure you are properly grounded before beginning any installation procedures. The following warnings apply to in-rack operations only: WARNING: Always begin by mounting the heaviest item on the bottom of the rack. Continue to populate the rack from the bottom to the top.
Memory Memory Quick Start Guidelines This section gives a brief overview of memory in the HP ProLiant ML530 Generation 2 servers, including: • Quick start DIMM installation • Quick start memory configuration • Quick start LED information More information about each of these items can be found in this chapter. Quick Start DIMM Installation Use the following table as a quick reference for DIMM installation guidelines specific to your desired memory configuration.
Memory Table 1-1: Quick Start DIMM Installation Guidelines continued Advanced ECC (Standard) Memory Online Spare Memory Single-Board Mirrored Memory Bank D must always be populated. Banks A and C must always be populated. Bank D is the online spare bank. Bank C mirrors bank A. Bank D mirrors bank B. Quick Start Memory Configuration If you plan to use online spare memory or single-board mirrored memory, you must configure your desired memory mode through RBSU. HP also recommends testing new DIMMs.

Amber Memory error has occurred and system has failed over to the mirrored bank(s). Off DIMM is not installed.
Memory Advanced ECC (Standard) Memory Technology This section details the features and DIMM installation requirements for advanced ECC memory. Features Advanced ECC memory has the following advantages: • The server can support up to 16 GB of system memory using 2-GB DIMMs. • Advanced ECC memory detects both single-bit and multi-bit errors, and corrects single-bit errors. It can also detect and correct 4-bit errors that occur within a single DRAM chip on a DIMM.
Memory Advanced Memory Protection Options The ProLiant ML530 Generation 2 server supports two types of optional Advanced Memory Protection: • Online spare memory • Single-board mirrored memory Each type includes Advanced ECC protection. Online Spare Memory Technology This section details the features and DIMM installation requirements for online spare memory. Features Online spare memory uses an online spare bank to provide additional memory protection.
Memory 3. Activates the online spare bank 4. Provides notification of the DIMM failure via the memory board LEDs, the front panel internal health LED, and Insight Manager 7 This process occurs without intervention or server interruption and enables you to replace the degraded DIMM at your convenience during a regularly scheduled shutdown.
Memory Single-Board Mirrored Memory Technology This section details the features and DIMM installation requirements for single-board mirrored memory. Features Single-board mirrored memory uses mirrored banks to provide a high level of memory redundancy. Single-board mirrored memory has the following advantages: • Single-board mirrored memory provides protection against multi-bit errors. If a DIMM on the memory board has a multi-bit error, the system reads from the mirrored banks instead.
Memory As long as no errors have occurred on the memory board, the system periodically switches which set of banks it reads from to be sure that both sets are monitored for memory errors. DIMM Installation Requirements In addition to the DIMM configuration requirements for advanced ECC memory, observe the following DIMM configuration requirements when installing DIMMs for single-board mirrored memory: • Bank C mirrors bank A, and bank D mirrors bank B. Banks A and C must always be populated.
Memory Memory Configuration Configuring your server’s memory system requires configuring both hardware and software. To configure your memory: 1. Remove the memory board. See “Removing a Memory Board” in this chapter. 2. Install the required DIMMs based on your desired memory mode. Be sure to follow all DIMM installation requirements. See the “DIMM Installation Requirement” section in this chapter for each mode. 3. Install the memory board. See “Installing a Memory Board” in this chapter. 4.
Memory Installation, Removal, and Replacement Procedures This section describes memory installation, removal, and replacement procedures. Removing a Memory Board CAUTION: Electrostatic discharge can damage electronic components. Be sure you are properly grounded before beginning any installation procedure. To remove a memory board: 1. Power down the server. Refer to “Powering Down the Server” in Chapter 3, “Installing Hardware Options,” in the setup and installation guide on the Documentation CD. 2.
Memory 3. Disengage the locking switch (1). 4. Press the release latches inward firmly, disengaging the board from the server (2). Do not squeeze the latches. 5. Lift the ejector levers up (3). 6. Pull the memory board up out of the server (4).
