Overview

...

The remote collector deployment should assist in 2 scenarios: 

• Data should be collected across several deployments but a consolidate single view is required (only one Local nodes is required).
• When a Local Node is reaching a CPU limit and an offload of work is required (can offload up to 20% CPU in high load).

...

The cell environment also referred as "federated environment" distribute DPOD's Store and DPOD's processing (using DPOD's agents) across different "federated" servers  combined into cell environment.

The overall cell can handle high loads of transaction (thousands of transaction per seconds).

The cell has two main components :

• Federated Cluster Member (FCM) / Cell Member - a DPOD server (usually physical) that includes Store data nodes (usually with local high speed storage) and agents (syslog and WSM) for collecting and parsing data. There could be one or more cluster members per cell.
• Cluster Manager / Cell Manager - Manage one or more FCM in a cell and also include additional DPOD services as reports, alerts, UI etc.

The following procedure describe the process of establishing DPOD Federated installation.

Prerequisites

1. The DPOD cell manager and cell FCM must be with the same version (minimum version is v1.0.9.0 )
2. DPOD ce ll manager can be both "Appliance Mode" or "Non Appliance Mode" installation with "medium" architecture type as detailed in the Hardware and Software Requirements. The manager server can be both virtual or physical.
3. DPOD cell member (FCM) should be "Non appliance Mode" installation with "High_20dv with High Load" architecture type as detailed in the Hardware and Software Requirements
4. Each cluster component (manager / FCM ) should have two network interfaces :
   
   1. External interface - for DPOD users to access UI and for communication between DPOD and Monitored Gateways.
   2. Internal Interface - for internal DPOD components communication (should be 10GB Ethernet interface, for more information see configuring FCM)
5. Each installation will requires some different ports to be opened in the firewall - see table 1

...

• DPOD cell member (FCM) should be "Non Appliance Mode" installation with "High_20dv with High Load" architecture type as detailed in the Hardware and Software Requirements.
• In addition to the "Non Applianc Mode" software requirements user should Install the following software packages (RPM) :
  • iptables
  • iptables-services
  • numactl

  • we also recommend installing some utilities packages useful for system maintenance and troubleshooting : telnet client, net-tools, iftop, tcpdump
