Set Cell Local Memory to 100% (cell-based servers only)
HP recommends that you set the Cell Local Memory (CLM) parameter to 100% to
maximum server performance. This setting allocates all available local cell RAM for the
use of that cell only, preventing unnecessary RAM reads and writes to physical RAM
accessed over the server backplane.
Modify CLM settings for each nPartitition using the nPartition command mangement
tool (parmodify). You must first install nPartition on the server to be modified, or on a
remote management station. See the nPartition Guide for detailed information on how to
install these tools.
To set the CLM parameter:
Step 1. From the server console, run the “parmodify” command with -p# and -m# options to
modify each cell’s attributes in each nPar you modify.
For example:
parmodify -p0 m0::::100%
where: -p is the partition number and -m is the cell number in that partition
sets cell local memory to 100% in cell 0, partition 0.
Step 2. Restart the server to make the changes active.
Locating the Microsoft Certificate of Authenticity
The certificate contains the CD-key for the Microsoft Windows Server 2003 OS. You must
enter this key as part of the installation procedure. Where the Certificate of Authority
(COA) is physically located depends on the HP Integrity server model.
