Cell Member Federation Post Steps

Updating service files for 4-CPU cell members

DPOD cell member is using NUMA (Non-Uniform Memory Access) technology.
The default cell member configuration binds DPOD's agent to NUMA node 0 and the Store's nodes to NUMA node 1.
If the server has 4 CPUs, the user should update the service files of nodes 2 and 3 and change the bound NUMA nodes to 2 and 3 respectively.

Identifying CPU amount

To identify Note: In case the cell member has only 2 CPUs - skip this step.

To verify the amount of CPUs installed on the server, use the NUMA utility:

numactl -s | grep cpubind

Expected output: policy: default
preferred node: current

To update the service files, execute the following command:

sed -i 's#/usr/bin/numactl --membind=1 --cpunodebind=1#/usr/bin/numactl --membind=2 --cpunodebind=2#g' /etc/init.d/MonTier-es-raw-trans-Node-2
sed -i 's#/usr/bin/numactl --membind=1 --cpunodebind=1#/usr/bin/numactl --membind=3 --cpunodebind=3#g' /etc/init.d/MonTier-es-raw-trans-Node-3

Updating service files for cell members with more than 384GB RAM

DPOD cell members with a high amount of RAM should assign more RAM to the Store services to ensure performance if storing and fetching data.

Note: In case the cell member has only 2 CPUs less than 384GB RAM - skip this step.

To update the service files, execute the following command:

sed -i 's#/usr/bin/numactl --membind=1 --cpunodebind=1#/usr/bin/numactl --membind=2 --cpunodebind=2#gs/^NODE_HEAP_SIZE=.*/NODE_HEAP_SIZE="64G"/g' /etc/init.d/MonTier-es-raw-trans-Node-1
sed -i 's/^NODE_HEAP_SIZE=.*/NODE_HEAP_SIZE="64G"/g' /etc/init.d/MonTier-es-raw-trans-Node-2
sed -i 's#/usr/bin/numactl --membind=1 --cpunodebind=1#/usr/bin/numactl --membind=3 --cpunodebind=3#gs/^NODE_HEAP_SIZE=.*/NODE_HEAP_SIZE="64G"/g' /etc/init.d/MonTier-es-raw-trans-Node-3
