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 supports 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 Advanced Memory Protection Options The server supports 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 correctable errors. Bank D on memory board 1 is configured as an online spare bank.
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. DIMM Installation Requirements In addition to the DIMM configuration requirements for advanced ECC memory, observe the following DIMM configuration requirements when installing DIMMs for online spare memory: • Memory board slot 1 must be populated.
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 uncorrectable 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. Uncorrectable errors are detected at the bank level rather than the DIMM level, so if an uncorrectable error occurs, all DIMMs in the bank must be replaced.
Memory Hot-Plug Mirrored Memory Technology This section details the features and DIMM installation requirements for hot-plug mirrored memory. Features 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 uncorrectable errors. If a DIMM on one memory board has an uncorrectable error, the system begins reading from the other memory board instead.
Memory 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. Hot-plug mirrored memory also provides hot-plug replacement capability. The server’s hot-plug capability enables you to hot-replace a memory board that has a failed or degraded DIMM on it.
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. Configuring the Memory Configuring the memory system of the server requires configuring both hardware and software.
Memory 4. Test the DIMMs and configure the memory mode through RBSU: a. Power on the server. b. Press the F9 key to enter RBSU. c. Select Advanced Options. d. Change POST Speed Up to disable. e. Press any key to return to the RBSU main menu. f. Select System Options. g. Select Advanced Memory Protection. h. Select the desired memory mode. i. Press the ESC key twice to go back to the main RBSU menu. j. Press the F10 key to exit RBSU. The server reboots and tests all memory in the system. k.
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. For detailed information, refer to the setup and installation guide on the Documentation CD.
Memory 2. Open the hot-plug door. Refer to 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. NOTE: If the “Ready to Hot Plug” LED is off on both boards, you must power down the server before replacing DIMMs. 3.
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 ML570 Generation 2 Server Memory Installation Guide HP CONFIDENTIAL Writer: Jennifer Hayward 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 Requirements” section 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.
