Im Networker Blog von Preston de Guise bin ich hier und hier auf eine höchst interessante Open Source Software gestoßen. MHVTL ist eine Virtual Tape Library, realisiert als Linux Kernel Modul plus Binaries zur Administration. Die Software simuliert eine SCSI Jukebox bei der die Anzahl und Typ der Bandlaufwerke, die Anzahl der Schächte und die Anzahl der Ein-/Ausgabeschächte frei konfiguriert werden können. Die virtuellen Bänder werden als Dateien gespeichert – die Standardgröße beträgt 500MB und kann ebenfalls konfiguriert werden. Da die Software unter /opt installiert wird sollte man ggf. einen eigenen Moutpoint dafür vorsehen.
Für MHVTL gibt es ein Supportforum, das ggf. bei Problemen weiterhelfen kann.
In meinem Beispiel habe ich in der VTL vier LTO4 Bandlaufwerke, 33 Schächte (Schacht 33 für Reinigung) und 4 E/A-Schächte eingestellt. Bestückt ist die VTL mit 20 LTO3 Bändern und 3 Reinigungsbändern.
