1-10 HP ProLiant ML530 Generation 2 Server Memory Installation Guide
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.
DIMM Installation Requirements
Observe the following DIMM configuration requirements when installing DIMMs:
Memory
• Use only industry-standard PC1600 registered DDR SDRAM DIMMs in
256-MB, 512-MB, 1-GB, and 2-GB capacities.
• Install DIMMs in pairs, one bank at a time.
• Be sure that both DIMMs in a bank are the same capacity.
• Be sure that bank A is populated.
IMPORTANT: HP recommends that you use only HP DIMMs. Third-party DIMMs may have
additional installation requirements. For information about third-party DIMM installation
requirements, refer to the Advanced Memory Protection white paper on the HP website:
www.hp.com/servers/proliant/manage
IMPORTANT: You must power down the server before installing additional DIMMs.
IMPORTANT: Follow all DIMM configuration requirements carefully. If the DIMMs are not
configured properly, you receive an error message during POST.
HP ProLiant ML530 Generation 2 Server Memory Installation Guide 1-11
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. Online spare memory has the following advantages:
• Online spare memory provides DIMM failover capabilities for single-bit
correctable errors. Bank D is configured as an online spare bank. If a DIMM
exceeds the HP predefined limit for single-bit correctable errors, indicating that it
may fail, the system fails over to the online spare bank.
• The server can support up to 12 GB of system memory and 4 GB of online spare
memory using 2-GB DIMMs.
IMPORTANT: DIMMs in the online spare bank must be of equal or greater capacity than the
DIMMs in the remaining banks.
Bank D is the online spare bank. The online spare bank can provide memory
protection for up to three other banks. If any DIMM in these three banks exceeds the
HP predefined limit for single-bit correctable errors, indicating that it may fail, the
system performs the following actions:
1. Copies the contents of the degraded bank to the online spare bank
2. Deactivates the failing bank
1-12 HP ProLiant ML530 Generation 2 Server Memory Installation Guide
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.
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:
• Bank D is the online spare bank and must be populated when the server is
configured for online spare memory.
• DIMMs installed in the online spare bank must be of equal or greater capacity
than each of those in the remaining banks.
IMPORTANT: If any one of the above requirements is not met, the system automatically
switches to advanced ECC memory and displays an error message during POST.
Memory
HP ProLiant ML530 Generation 2 Server Memory Installation Guide 1-13
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.
• The server can support up to 8 GB of system memory and 8 GB of redundant
memory using 2-GB DIMMs.
IMPORTANT: DIMMs in the redundant banks must be configured identically to the banks they
are mirroring.
IMPORTANT: If a DIMM exceeds the HP predefined limit for single-bit correctable errors, the
system does not fail over to the redundant banks, but does notify you of the condition through
Insight Manager 7, the memory board LEDs, and the front panel internal health LED.
In a server configured for single-board mirrored memory, bank C mirrors bank A,
and, if populated, bank D mirrors bank B. If any DIMM in bank A or bank B has a
multi-bit error, the system performs the following actions:
1. Rereads the correct data from the redundant memory banks
2. Performs all future reads from the redundant memory banks
3. 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. 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.
1-14 HP ProLiant ML530 Generation 2 Server Memory Installation Guide
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.
• DIMMs in the mirrored banks must be configured identically to the banks they
are mirroring. Corresponding banks (for instance, bank A and bank C) must be
populated with DIMMs of the same capacity.
IMPORTANT: If any one of the above requirements is not met, the system automatically
switches to advanced ECC memory and displays an error message during POST.
Software
Memory
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 and single-board mirrored memory features
do not require special software drivers and are operating system independent.
