Great post over on The Deployment Guys.
One of the great features of MDT 2010/2012 is the ability to create a media based deployment – this media based deployment can be placed on a USB based memory device (HDD or Fob) or onto a DVD. This allows the MDT based deployment to run from this removable media which is great for badly connected environments or portable build requirements.
Many customers I work with like to use DVD media based deployment as MDT 2012/2012 automatically creates a .ISO file that can be burnt to DVD and in most cases this gives them up to 8.5 GB on a dual layer DVD – it’s also a cheap deployment mechanism. However there are some occasions where this amount of DVD space just isn’t enough and a combination of image size and MDT distribution share content pushes the requirement for storage over the limit of the DVD. You could at this point switch to using USB based devices or you can read on and use the solution discussed in this post.
