Definition

A SEP sesam DataMover is a functional role, which allows an access to a 3rd party software API. This DataMover role can be combined with a SEP sesam component (Sesam server, RDS or client). Which Sesam component is possible for combination depends on 3rd party software. Hereinafter the existing Sesam DataMovers are described.


DataMover Types

  • SEP sesam DataMover for VMware vSphere (SDM-VV)
  • SEP sesam DataMover for Citrix XenServer (SDM-CX)
  • SEP sesam DataMover for Novell Services (SDM-NS)


SEP sesam DataMover for VMware vSphere (SDM-VV)

Voraussetzungen

  • Operating system MS Windows Server 2003/2008 [R2]
  • In the upcoming SEP sesam version 4.2 a SDM-VV on Linux will be supported !!
  • 4GB main memory
  • 50 GB harddisk
  • A SEP sesam component (Sesam server, RDS or client) must be installed. A regular path backup has to work.
  • Installation of the VMware VDDK version 5.0

Recommendation

Based on a VMware VDDK restriction, the SDM-VV should run on a physical machine not on a VM. When the SDM-VV operates on a VM, it is not possible to backup a VM, which runs on the same ESXi hypervisor and is stored on the same VMware Datastore like the Sesam DataMover (SDM-VV).

Function

To request of the VMware farm inforamtion, the SEP sesam server connects usually to the central vCenter server. All control tasks will be handled there:

  • From which objects have the VM ?
  • On which ESXi hypervisor the VM is running ?
  • Create and remove of VM snapshots

When all preparatory activities for backup or restore are completed with the vCenter server, the actual VM data will be picked up by the VMware VDDK the Sesam DataMover from the corresponding ESXi server and transport to the media server (Sesam server or RDS).

If the Sesam DataMover (SDM-VV) has access to the same SAN LUNs that sees the ESXi hypervisor, and the SDM-VV works on a SEP Sesam SAN Remote Device Server (SAN-RDS) component, then on the SDM-VV, the data of the VM can be transported directly from the central storage to the storage device (LAN-free).


SEP sesam DataMover for Citrix XenServer (SDM-CX)

Voraussetzungen

  • Operating system MS Windows or Linux
  • 2 GB main memory
  • A installed SEP sesam component (Sesam server, RDS or client). A regular path backup has to work.

Funktion

Sind mehrere Citrix XenServer in einem Pool organisiert, dann sollte der DataMover immer direkt mit dem Pool-Master kommunizieren. Der Pool-Master teilt dem DataMover beim Start des Backup mit, auf welchem Citrix XenServer die VM aktuell läuft und stößt automatisch ein einen KOmmunilationwechsel zum entsprechenden Citrix XenServer an (Mapping).


* SEP sesam DataMover für Novell Services (SDM-NS)

Voraussetzungen

  • Betriebssystem Novell OES2 Linux oder Novell OES11. Es muss kein eDirectory oder ein anderer Novell Dienst auf dieser Maschine installiert sein. Nur die Novell SMS-Komponenten (SMDR, TSAs) werden benötigt.
  • 2 GB Hauptspeicher
  • Eine Sesam Komponente (Client, RDS oder Sesam Server) muss installiert sein. Ein Pfad-Backup muss möglich sein.
  • Sesam Novell Client muss installiert sein
