Installing the Server Blade and Options
Memory
The server blade supports up to six 2-GB, PC2100, Registered, ECC DDR DIMMs.
The following sections explain DIMM slot locations, installation guidelines, and
installation procedures.
Online Spare Memory Configuration
With Online Spare Memory, you can configure primary server memory for up to
8 GB of ECC DDR memory and configure an additional 4 GB of online spare
memory. In this configuration, all six DIMM slots are populated with 2-GB
Registered ECC DDR DIMMs.
NOTE: Bank A refers to DIMM slots 1 and 2; bank B refers to DIMM slots 3 and 4; bank C
refers to DIMM slots 5 and 6.
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.
For example, if bank A is populated with two 256-MB DIMMs and bank B is
populated with two 512-MB DIMMs, bank C must be populated with two
512-MB or greater DIMMs in order for online spare memory support to function
properly.
