FBDIMM pairs in a memory bank must  have identical HP part numbers. 
• FBDIMMS must be populated as spec ified for each AMP memory mode. 
The memory subsystem for this server  is divided into two branches. Each memory branch is essentially a 
separate memory controller. The FBDIMMs map to the tw o branches as indicated in the following table: 
 
Branch 0  Branch 1 
FBDIMM 1A  FBDIMM 5B 
FBDIMM 3A  FBDIMM 7B 
FBDIMM 2C  FBDIMM 6D 
FBDIMM 4C  FBDIMM 8D  
This multi-branch architecture provides enhanced performance in Advanced ECC mode. The concept of 
multiple branches is important for the operation  of online spare mode and mirrored memory mode. 
If the server contains more than 4 GB of memory , consult the operating system documentation about 
accessing the full amount of installed memory. 
 
Advanced ECC memory 
Advanced ECC memory is the default memory protecti on mode for this server. In Advanced ECC, the 
server is protected agains t correctable memory errors. The server pr ovides notification if the level of 
correctable errors exceeds a pre-defined threshold rate . The server does not fail because of correctable 
memory errors. Advanced ECC provides additional prot ection over Standard ECC because it is possible 
to correct certain memory errors th at would otherwise be uncorrectable and result in a server failure.  
Whereas standard ECC can correct single-bit memo ry errors, Advanced ECC can correct single-bit 
memory errors and multi-bi t memory errors if all failed bits  are on the same DRAM device on the 
FBDIMM. 
In addition to general configuration requiremen ts, Advanced ECC memory also has the following 
configuration requirements: 
•  FBDIMMs must be installed in pairs. 
• FBDIMMs must be installed in sequenti al order, beginning with bank A. 
In Advanced ECC mode, FBDIMMs must be popu lated as specified in the following table: 
 
Configuration Bank A 
1A and 3A Bank B 
5B and 7B Bank C 
2C and 4C Bank D 
6D and 8D 
1  X  — — — 
2 X X — — 
3 X X X — 
4 X X X X   
Online spare memory configuration 
Online spare memory provides prot
ection against degrading FBDIMMs  by reducing the likelihood of 
uncorrectable memory errors. This protection is  available without any operating system support. 
An understanding of single-rank and dual-rank FBDI MMs is required to understand memory usage in 
online spare mode. FBDIMMs can ei ther be single-rank or dual-rank. Certain FBDIMM configuration 
requirements are based on these classifications. A du al-rank FBDIMM is similar to having two single-rank 
FBDIMMs on the same module. Although only a sing le FBDIMM module, a dual-rank FBDIMM acts as two 
separate FBDIMMs. The purpose of du al-rank FBDIMMs is to provide the largest capacity FBDIMM for the  
						

							
 
Hardware options  installation 39 
current DRAM technology. If the cu rrent DRAM technology allows for 2-GB single-rank FBDIMMs, a dual-
rank FBDIMM using the same technology would be 4-GB. 
In online spare mode, a single rank  of memory acts as the spare memory. For single-rank FBDIMMs, the 
entire FBDIMM acts as the spare  memory. For a dual-rank FBDIMM, only half of the FBDIMM acts as the 
spare memory while the other half is availabl e for operating system and application usage. 
If one of the non-spare FBDIMMs receives correctable  memory errors at a higher rate than a specific 
threshold, the server automatically copies the memory  contents of the degraded rank to the online spare 
rank. The server then deactivates th e failing rank and automatically swit ches over to the online spare. 
Because FBDIMMs that experience a high rate of  correctable memory errors also have a higher 
probability of receiving an uncorrectable memory er ror, this configuration reduces the likelihood of 
uncorrectable memory errors that  would result in server downtime. 
Online spare is performed per bran ch of the memory controller. For a server with both branches 
populated, two ranks are used for online spare memo ry. One branch can fail over to the associated 
online spare while the other  branch is still protected. 
Each branch is made up of two banks: 
•  Branch 0 contains banks A and C 
• Branch 1 contains banks B and D 
Online spare FBDIMM configuration requirements (in  addition to general configuration requirements): 
• When only bank A is being used, it must  be fully populated with dual-rank FBDIMMs. 
• If banks A and C are being used, they must be fully populated. 
• If installed, bank A and bank C must contain FBDIMMs with identical part numbers.  
• If installed, bank B and bank D must also co ntain FBDIMMs with identical part numbers. 
In online spare mode, FBDIMMs must be popu lated as specified in the following table: 
 
Configuration Branch 0 
Bank A 
1A and 3A Branch 0 
Bank C 
2C and 4C Branch 1 
Bank B 
5B and 7B Branch 1 
Bank D

1* X  — — — 
2 X X — — 
3 X X X X  
* Configuration 1 is only supported if usin
g bank A, populated with dual-rank FBDIMMs. 
After installing FBDIMMs, use RBSU to configure the system for online spare memory support 
(Configuring online spare memory  on page 69). 
 
Mirrored memory configuration 
Mirroring provides protecti on against uncorrectable memory errors  that would otherwise result in server 
downtime. 
Mirroring is performed on the branch level.  Branch 0 and branch 1 mirror each other. 
Each branch maintains a copy of all memory contents. Memory  writes go to both branches. Memory 
reads  come from only one of the two branches (unless  an uncorrectable error occurs). If a memory read 
on one branch returns incorrect data due to an un correctable memory error, the system automatically 
retrieves the proper data from the other branch. A  branch is not necessarily disabled (thus losing 
mirroring protection) because of a si ngle uncorrectable error. Mirroring protection is not lost because of 
transient and soft uncorrectable errors, resulting in sy stems that maintain mirroring protection (and thus 
improved uptime) unless there is  a failure of both branches.

After installing FBDIMMs, use RBSU to configure the system for mirrored memory support (
Configuring 
mirrored memory  on page 69). 
 
Installing FBDIMMs 
1. Power down the server (on page  18). 
2. Extend the server from the rack (on page  19). 
3. Remove the access panel (on page  20). 
4. Open the FBDIMM slot latches. 
5.  Install the FBDIMM. 
 
6. Install the access panel (on page  20). 
7. Slide the server into the rack. 
8. If you are installing FBDIMMs in an online spare or mirrored configuration, use RBSU ( HP ROM-
Based Setup Utility  on page 68) to configure this feature. 
 
Hot-plug SAS and SATA hard drive options 
When adding hard drives to the server, observe the following general guidelines:  
• The system automatically sets all device numbers. 
• If only one hard drive is used, install it in the bay with the lowest device number ( SAS and SATA 
device numbers  on page 15).
