Ken,

        On this I will need to respectfully disagree, seems I work with this 
product every day and this is not accurate.  The DLm is 100% evolution of the 
BusTech MDL and we see this constantly in the product.  Is it different yes, 
has it evolved yes, and the evolution is from BusTech MDL.  I have worked on 
this product from the time it was acquired by EMC now Dell. And another fun 
relatively unknow BusTech fact at one time for a short while they were owned by 
StorageTek (STK).  This happened because BusTech was acquired by Network 
Systems Corp who was then acquired by STK. After that the principals of BusTech 
were able to buy their company back from STK.

That’s not true!  EMC purchased BUSTECH and killed their product.  DLm is an 
internal EMC development and had nothing to do with the BUSTECH products.

    Just a small point of clarification BUSTECH was purchased by EMC in the 
2010 / 2011 time frame and from that come the DLm.

The "former BUSTECH" is also claimed by OPTICA (the people who make converters 
and directors), for their z/VT product.  It's a lot closer to the original 
BUSTECH than DLm, but they could both be based on the same technology.
