NovaScale Blade BL265 - Installation and User's Guide
3.8 Installing a memory module
Use these instructions to install memory modules in the blade server.
The blade server has a total of twelve direct inline memory module (DIMM) slots. The blade
server supports very low profile (VLP) DDR3 DIMMs with error code correction (ECC) in 1
GB, 2 GB, 4 GB and 8 GB capacities.
After you install or remove a DIMM, you must change and save the new configuration
information by using the Setup utility. When you turn on the blade server, a message
indicates that the memory configuration has changed. Start the Setup utility and select Save
Settings (see Setup Utility menu on page 54 for more information) to save changes.
The memory is accessed internally through the system using six channels. Each channel
contains two DIMM connectors. The following table lists each channel and which DIMM
connectors belong to the channel.
Memory channel DIMM connector
Channel 0 DIMM connector 1 and 2
Channel 1 DIMM connector 5 and 6
Channel 2 DIMM connector 3 and 4
Channel 3 DIMM connector 7 and 8
Channel 4 DIMM connector 11 and 12
Channel 5 DIMM connector 9 and 10
Table 3-1. Memory channel configuration
Depending on the memory mode that is set in the Setup utility, the blade server can support
a minimum of 4 GB and a maximum of 48 GB of system memory on the system board in a
blade server with one processor. If two microprocessors are installed, the blade server can
support a minimum of 8 GB and a maximum of 96 GB of system memory. There are two
different memory modes:
•
Independent channel mode: Independent channel mode gives a maximum of 48 GB of
usable memory with one CPU installed, and 96 GB of usable memory with 2 CPUs
installed (using 8 GB DIMMs). The DIMMs can be installed without matching sizes.
See the table below for the memory installation order.
