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 ProLiant ML500 series Generation 2 servers support up to 32 GB of system memory. Each memory board supports 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.
Memory IMPORTANT: Follow all DIMM configuration requirements carefully. If the DIMMs are not configured properly, you receive an error message during POST. Advanced Memory Protection Options The ProLiant ML500 series Generation 2 servers support three types of optional Advanced Memory Protection: • Online spare memory • Single-board mirrored memory • Hot-plug mirrored memory Each type includes Advanced ECC protection. NOTE: Hot-add capabilities will be available in a future software release.
Memory 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. Online spare memory has the following advantages: • Online spare memory provides DIMM failover capabilities for single-bit correctable errors. Bank D on memory board 1 is configured as an online spare bank.
Memory • 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 on a single memory board 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.
Memory This process occurs without intervention or server interruption, and enables you to replace the degraded DIMM at your convenience during a regularly scheduled shutdown. Multi-bit errors are detected at the bank level rather than the DIMM level, so if a multi-bit error occurs, both DIMMs in the bank must be replaced. 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.
Memory Hot-Plug Mirrored Memory Technology This section details the features and DIMM installation requirements for hot-plug mirrored memory. Features NOTE: Hot-plug mirrored memory mode is not available on ProLiant ML530 generation 2 servers. Hot-plug mirrored memory uses an additional memory board to provide complete memory redundancy. Hot-plug mirrored memory has the following advantages: • Hot-plug mirrored memory provides protection against multi-bit errors.
Memory This process occurs without intervention or server interruption, and enables you to hot-replace the failed or degraded DIMM at your convenience. Multi-bit errors are detected at the bank level rather than the DIMM level, so if a multi-bit error occurs, both DIMMs in the bank must be replaced. As long as no errors have occurred on the memory board, the system periodically switches which memory board it reads from to be sure that both memory boards are monitored for memory errors.
Memory Software The following software components of the memory system provide memory configuration and management capabilities: • ROM-Based Setup Utility (RBSU) • Insight Manager 7 IMPORTANT: The optional online spare memory, single-board mirrored memory, and hot-plug mirrored memory features do not require special software drivers and are operating system independent.

Memory Configuring the Memory Configuring the server’s memory system requires configuring both hardware and software. To configure your memory: 1. Remove the memory board. Refer to “Removing a Memory Board” in this chapter. 2. Install the required DIMMs based on your desired memory configuration. Be sure to follow all DIMM installation requirements. Refer to “DIMM Installation Requirements” for your desired memory configuration in this chapter. 3. Install the memory board.
Memory Installation, Removal, and Replacement Procedures DIMM and memory board installation, removal, and replacement procedures can be either hot-plug or non-hot-plug procedures, depending on how the server is configured.
Memory CAUTION: Be sure to power down the server when performing these procedures in a server that is not configured for hot-plug mirrored memory. Observe the following warnings when performing a hot-plug replacement procedure: WARNING: Always comply with all electrostatic and thermal guidelines to prevent bodily injury and ensure a properly functioning system when performing hot-plug operations.
Memory 2. Open the hot-plug door. Refer to “Opening the Hot-Plug Door” in Chapter 3, “Installing Hardware Options,” in the setup and installation guide on the Documentation CD. Hot-replacement procedure: Determine which memory board you want to remove by locating the memory board with an amber memory status LED and one or more amber DIMM status LEDs. The “Ready to Hot Plug” LED must be green, indicating that you can perform a hot-plug procedure.
Memory 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). Hot-replacement procedure: While the memory board with the failed or degraded DIMM is being replaced, the system continues to read and write from the operational memory board.
Memory Removing a DIMM To remove a DIMM: 1. Remove the memory board. Refer to “Removing a Memory Board” in this chapter. 2. Place the memory board on a level surface. 3. Open the DIMM slot latches (1) to eject the DIMM from the DIMM slot (2). Figure 1-5: Removing a DIMM HP ProLiant ML500 Series Generation 2 Server Memory Installation Guide HP CONFIDENTIAL Writer: Jim Yurick File Name: b-ch1 Memory.
Memory Installing a DIMM To install a DIMM: 1. Remove the memory board. Refer to “Removing a Memory Board” in this chapter. 2. Observe all DIMM installation requirements for your desired memory mode. Refer to the “DIMM Installation Requirement” sections for each mode in this chapter. IMPORTANT: Follow all DIMM configuration requirements carefully. If the DIMMs are not configured properly, you receive an error message during POST and the DIMM LEDs flash amber. 3.
Memory Installing a Memory Board To install a memory board: 1. Align the memory board with the memory slot and memory board guide clips. 2. Slide the memory board into the server (1) and close the ejector levers to seat the memory board firmly (2). Hot-replacement procedure: Any LEDs that were amber when the board was removed from the server now illuminate amber again. IMPORTANT: The LEDs re-illuminate amber during this step to enable you to see which DIMM failed.
Memory 3. Engage the locking switch (3). Hot-replacement procedure: All LEDs now turn off except the memory status LED, which flashes green while data are copied from one memory board to the other. This process may take up to a minute to complete. When the copying process is complete, the other LEDs re-illuminate as described in Table 1-10. CAUTION: Do not remove the memory board while the memory status LED is flashing. When the memory status LED is flashing, the memory board is transferring data.
Memory 6. Reference the LEDs on the top of the memory board to be sure that the memory is functioning properly. Table 1-10 describes what the LED states for each memory configuration when the DIMMs and memory board are installed and functioning properly. For more information on LEDs, refer to “Memory Board LEDs” in this chapter.
