Wrap up

Fibre Channel ist die richtige Technik um Speichernetzwerke aufzubauen. iSCSI dient zur Anbindung von einfachen Servern an bestehende Fibre Channel

  • Speicher. Es wird Fibre Channel nicht ablösen, es wird Fibre Channel ergänzen.

iFCP ist die bessere Technik zum Verbinden von Speichernetzen und bietet viele Vorteile gegenüber herkömmlichen Verfahren. FCIP ist weit verbreitet, hat aber Nachteile, weil das FC Protokoll nur „gebridged“

  • wird. Das FC Paket bleibt erhalten.

Mit iFCP ist es möglich Speichernetze verschiedener Hersteller miteinander zu verbinden ohne das die verschiedenen SANs miteinander „verschmelzen“. Die Nutzung von bestehenden IP Verbindungen für Speichernetzwerke ist möglich, es gilt aber Rücksicht zu nehmen auf beschränkte Bandbreiten im IP Netzwerk.
