Connector Overview

For more information and a deep technical understanding of the EMC architecture and CEE, refer to the EMC CEE version 7.0 using the Common Event Enabler for Windows https://www.emc.com/collateral/TechnicalDocument/docu48055.pdf

Physical & Virtual Data Mover

  • Celerra/VNX architecture is based on physical components named data movers.
  • A physical data mover can host multiple virtual data movers (VDMs).

Audit facility (CEPA) is single for each physical data mover, and must be configured separately for each physical data mover.

CIFS Server

  • A CIFS server is an EMC component that corresponds to a file server (\\cifs_server_name).
  • You can configure a CIFS server on a physical Data Mover or on a VDM. Typically, the CIFS servers are configured on a VDM.
  • Every CIFS server requires an Application definition in File Access Manager.

CIFS Servers Aliases

  • An alias is a synonym name of the CIFS server. It is defined in the CIFS server itself and is visible in the EMC Unisphere.
  • Every CIFS server can have one or more aliases.
  • All the activities are always saved in File Access Manager with the real name of the filer.
  • The filer name configured in the application must be the real name only.

  • A DNS alias is not an EMC alias.

    You must configure the aliases in the application configuration as well. Failure to do so results in losing the events of users accessing the aliases.

NFS Exports

  • An NFS export is an EMC component that can be associated with any existing network interface to expose a UNIX-style NFS file server.
  • Every NFS network interface that exposes NFS exports requires an Application definition in File Access Manager.

CEE

  • A CEE service is the EMC gateway for communicating and receiving events notifications from the data movers.
  • All data movers send notifications on CIFS/NFS events to the CEE service. The service in the data mover responsible for sending the events to the CEE is called CEPA (Celerra Event Publishing Connector).
  • There is an n:n relation between the CEPA service running on the data mover and the CEE service:
  • Every CEE can communicate with multiple data movers.
  • Every CEPA service on a data mover can communicate with multiple CEE servers (for high availability and load sharing).

CEPA and Virtual Data Movers

  • For CEE to work, you need to have a CIFS server configured on the physical Data Mover. This is the global CIFS server or the default CIFS server on the physical Data Mover.

CEE & Activity Monitor

  • Every Activity Monitor can communicate with one or more CEE servers.
  • Every CEE service can be configured to work with a multiple Activity Monitor services.

Activity Monitor

  • Each Activity Monitor in File Access Manager corresponds to a single CIFS server.
    The first Activity Monitor installed on a physical server creates the Activity Monitor service. Subsequent Activity Monitors installed will not create additional Activity Monitor services.
  • Every Activity Monitor that is installed adds a bamconfig.xml file under the Activity Monitor to add itself to the same service.

The first installed Activity Monitor must be the last Activity Monitor uninstalled. If you uninstall the first Activity Monitor before uninstalling the other installed Activity Monitors, those Activity Monitors will not work, and it will not be possible to uninstall them.
