  1. DPOD cell manager and federated cell members must be with the same version (minimum version is v1.0.8.5).
  2. DPOD cell manager can be installed in both Appliance Mode or Non-Appliance Mode with Medium Load architecture type, as detailed in the Hardware and Software Requirements. The manager server can be both virtual or physical.
  3. DPOD federated cell member (FCM) should be installed in Non-appliance Mode with High_20dv with High Load architecture architecture type, as detailed in the Hardware and Software Requirements.
  4. Each cell component (manager / FCM) should have two network interfaces:
    1. External interface - for DPOD users to access the Web Console and for communication between DPOD and Monitored Gateways.
    2. Internal interface - for internal DPOD components inter-communication (should be a 10Gb Ethernet interface).
  5. Network ports should be opened in the network firewall as detailed below:

  1. To identify which of the server's NVMe disk bays is bound to which of the CPUs, use the hardware manufacture documentation.
    Also, write down the disk's serial number by visually observing the disk.

  2. In order to identify the disk OS path (e.g.: /dev/nvme01n) and the ,  disk serial, install the NVMe disk utility software provided by the hardware supplier. For example: for Intel-based NVMe SSD disks, install "Intel® SSD Data Center Tool" (isdct).

Preparing Local OS Based Firewall

Most Linux-based OS uses a local firewall service (e.g.: iptables / firewalld).

Since the OS of the Non-Appliance Mode DPOD installation is provided by the user, it is under the user's responsibility to allow needed connectivity to and from the server.

User should make sure needed connectivity detailed in Network Ports Table is allowed on the OS local firewall service.

Note

When using DPOD Appliance mode installation for the cell manager, local OS based firewall service is handled by the cell member federation script.

Cell Member Federation

In order to federate and configure the cell member, run the following script in the cell manager once per cell member.

For instance, to federate two cell members, the script should be run twice (in the cell manager) - first time with the IP address of the first cell member, and second time with the IP address of the second cell member.

Important: The script should be executed using the OS root user.

Cell Member Federation Post Steps

NUMA configuration

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

Identifying NUMA Configuration

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

Preparing Local OS Based Firewall

Most Linux-based OS uses a local firewall service (e.g.: iptables / firewalld).

Since the OS of the Non-Appliance Mode DPOD installation is provided by the user, it is under the user's responsibility to allow needed connectivity to and from the server.

User should make sure needed connectivity detailed in Network Ports Table is allowed on the OS local firewall service.

Note

When using DPOD Appliance mode installation for the cell manager, local OS based firewall service is handled by the cell member federation script.

Cell Member Federation

In order to federate and configure the cell member, run the following script in the cell manager once per cell member.

For instance, to federate two cell members, the script should be run twice (in the cell manager) - first time with the IP address of the first cell member, and second time with the IP address of the second cell member.


Important: The script should be executed using the OS root user.

In case of a failure, the script will try to rollback the configuration changes it made, so the problem can be fixed before rerunning it again.

Cell Member Federation Post Steps

NUMA configuration

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

Identifying NUMA Configuration

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

Code Block
themeRDark
numactl -s

Example output for 4 CPU server :

policy: default
preferred node: current
physcpubind: 0 1 2 3 4 5 6 7 8 9 10 11 12 
cpubind: 0 1 2 3
nodebind: 0 1 2 3
membind: 0 1 2 3
Alter Syslog agents

The services files are located on the directory /etc/init.d/ with name prefix MonTier-SyslogAgent- (should be 4 service files)

Look in the service file the string "numa" and make sure the numa variable definition is as follows :

Code Block
themeRDark
numa="/usr/bin/numactl --membind=0 --cpunodebind=0"

/bin/su -s /bin/bash -c "/bin/bash -c 'echo \$\$ >${FLUME_PID_FILE} && exec ${numa} ${exec}......


Alter Store's Node 2 and 3 (OPTIONAL - only if the server has 4 CPUs)

The services files are located on the directory /etc/init.d/ with the namea name MonTier-es-raw-trans-Node-2 and MonTier-es-raw-trans-Node-3.
