LONDON, July 10 (Reuters) – The quickest way to attract a marriage proposal is to draw the attentions of a rival suitor.

When Data Domain <DDUP.O> agreed terms with fellow data storage company Network Appliance <NTAP.O> it concentrated minds at EMC <EMC.N>.

The upshot is that EMC is now paying an eye-watering six times sales for Data Domain, one-third more than NetApp first proposed to pay.

EMC could not bear to simply stand and watch. Data Domain has technology¬†that threatens EMC’s business model. Its products reduce demand for existing data storage hardware by as much as 20 times.
