May I suggest something; look at the history of Overland, because quite simply that is all that this company is today,.
Glassware was a product of 100% pure hype. Want proof? Ask the execs how all those POCs are proceeding. Remember the "chaos of success" they openly bragged about. Remember all the BIG partner action? Ok, its mod 2017. Where is the revenue from ALL of this activity? Can the company name a single client the uses Glassware today?
So, what remains is removable disk and low end storage and tape. Guess what, there is little company called Amazon that is killing legacy storage companies like EMC and NetApp. These two firms do more business in a day than Sphere does in a year. They have advanced solutions Sphere could only dream of being able to sell.
The Overland business has not made a profit in something like nine years now. If you think that is a good value proposition then I suggest you mortgage the house and go all in.
