DESCRIPTION

An HP ProLiant DL380 G4 server configured with an HP DVD-ROM drive (Option Kit 264007-B21, Spares Kit 268795-001, "SPS-DRV,DVD,8/24X,SLIM") and running VMware ESX Server 2.5.x will exhibit very slow performance when copying files from the DVD-ROM drive to a virtual machine local folder. For example, copying a 600 MB file to a Microsoft Windows virtual machine may require about 2.5 hours, rather than the expected time of 20 minutes (or less).

This occurs because ESX Server library files for DVD-ROM emulation were not included in ESX Server 2.5.x.

SCOPE

Any HP ProLiant DL380 G4 server configured with an HP DVD-ROM drive (Option Kit 264007-B21, Spares Kit 268795-001, "SPS-DRV,DVD,8/24X,SLIM") and running VMware ESX Server 2.5.x.

RESOLUTION
