Dimm Installation Guidelines; Online Spare Memory Configuration - HP ProLiant DL360 SERIES User Manual

DIMM Installation Guidelines

You must observe the following guidelines when installing additional memory:
•
DIMMs installed in the server must be Registered DDR2 DRAM, 2.5 volts,
64 bits wide, and ECC.
•
DIMMs in slots 1A and 2A must match and must be installed as a pair.
•
DIMMs in slots 3B and 4B must match and must be installed as a pair.
•
DIMMs in slots 5C and 6C must match and must be installed as a pair.
•
All DIMMs installed must be the same speed. Do not install DIMM modules
supporting different speeds.
•
Install DIMMs into both slots within a single bank. DIMMs must be installed
in order. Upgrade memory by installing DIMM pairs into banks in sequential
bank order, starting with bank B.

Online Spare Memory Configuration

With online spare memory, you can configure primary server memory for up to
6 GB of ECC DDR2 SDRAM and configure an additional 6 GB of online spare
memory. In this configuration, all six DIMM slots are populated with up to 2-GB
Registered ECC DDR2 SDRAM DIMMs.
In the online spare configuration, the ROM automatically configures the last
populated bank as the spare memory. 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.
NOTE: When configuring the memory sub-system to run in Online
Spare mode, only single rank DIMMs can be installed in the system.
Online Spare Mode will not work with dual rank DIMMs installed in the
system.
