HP ProLiant DL380 Generation 4 Server Reference and Troubleshooting Guide
Memory Options
You can expand server memory by installing PC2-3200 Registered DDR-2
SDRAM DIMMs. The system supports up to six DIMMs.
NOTE: The Advanced Memory Protection option in RBSU provides
additional memory protection beyond Advanced ECC. By default, the
server is set to Advanced ECC Support. Refer to "ROM-Based Setup
Utility (on page
)," on the Documentation CD, for more information.
The server supports two types of memory configurations for 3.4-GHz or greater
models:
·
·
Standard memory configuration for maximum performance with up to 12 GB
of active memory (six 2-GB memory modules)
Online spare memory configuration for maximum availability with up to
8 GB of active memory and 4 GB of online spare memory
Refer to "DIMM Slots (on page
)" for DIMM slot locations and bank
assignments.
Online Spare Memory Configuration
In the online spare configuration, the ROM automatically configures the last
populated bank as the spare memory. If only banks A and B are populated,
bank B is the spare bank. If banks A, B, and C are populated, bank C is the spare
bank. If DIMMs in a non-spare bank exceed the limit for the single-bit
correctable errors threshold as defined by the Pre-Failure Warranty, the system
copies the memory contents of the failing bank to the spare bank. The system
then deactivates the failing bank and automatically switches over to the spare
bank.
For online spare memory support, you must observe the following guidelines:
·
·
The ROM must be up to date.
DIMMs installed in a spare bank must be of equal or greater capacity than
the DIMMs installed in other banks.
