We've spoken with HashFast already and they have assured us that they have sufficient quantity of the chips available immediately for what we need. We do have a couple chips ready now (that you can see in the picture) that are just waiting for the boards to be built so they can be tested.
While I wish you all the best with your project, I regret you used Hashfast as your partner.
As a Hashfast customer, I can tell you from experience they have only delivered a fraction of the pre-orders they took. There are thousands of units (MPP on the BBJets Batch #1, Upgrade kits for the BBJets, Batch #2 "Sierra"s and MPP on the Sierra's) that still need to ship out and customers have been waiting for months without any updates or info. They changed their TOS on a few occasions to minimize the cost of refunds, and so an and so an.
If they now start bulk shipping you chips, they are actually reselling inventory that should have been gone to their own customers. Do you really want to do business with a company that uses such despicable practices? You'll end of holding the short end of the stick, like many others (the custom hardware forum has a few threads like
https://bitcointalksearch.org/topic/m.5772340) like Icedrill.
As a B1 HashFast customer who also has not received his hardware, I sympathize with you. I do not have a huge amount of insight into the inner workings of the company, but my understanding is that HashFast is not short on chips; the infact have an excess of them. The delays are related to other issues they have with their supply and production chain. I know people don't want to hear it, but sometimes the main component you're designing for is actually the easiest to get. It's all the other stuff that you built in but when you go to actually buy them, there's none to be found. I was actually looking to use one cool part in particular with the Habanero (the IR3575 integrated PowIRstage), but I just couldn't find any real stock anywhere in the channel. Even going direct to IR, the leadtime is 17-19 weeks plus be screened and approved with a minimum $500k annual volume to set up a direct account.
I can't speak to how accurate all my information is and I'm not sure an official post from HashFast explaining all the reasons that the products are delayed is going to be forthcoming, but all I can say on the chip issue is that I've been told that the sale of excess chip inventory doesn't take product from the existing preorder customers since chips aren't the limiting factor they have.
