Innovate or die.
That's the way it is in storage. The DotHill product is a good performer and doesn't break the bank for the SMB marketplace, but it's a legacy platform. There hasn't been any major innovation on the product for a long time.
The last time I had my folks do a pricing exercise for remote office storage, NetApp FAS2240 came in at several thousand dollars less than an HP P2000. As a result, we now have a FAS2240 in one of our remote offices handling file and block duties.
