I'm surprised they didn't increase the card's PCIe lanes to accommodate all of those m.2 drives. My guess is the ASIC can only handle so much data it couldn't saturate more than x4. If that's not the case then I'm curious what the reason is.
You are right, it's probably not a very sophisticated ASIC. This is the first time something like this has been put together so it isn't going to be a well optimized ASIC...it took years for bitcoin mining ASIC's to become ultra-optimized and demand for that probably wasn't much higher than demand for a 24TB SSD.
That said, more information on the ASIC would be interesting.
They aren't M.2 drives, they're only piggybacking on the form factor. The whole point of these drives is to do local analytics on the data and avoid pushing anything more over the external bus than they need to push. You're not thinking about dense servers with 10+ of these cards. Taking advantage of local on-card searches and analytics is the big push - you can't get the data out of the server fast enough to justify putting more bandwidth on any one of the cards.
Such cards and such capacity should be at least an x8 PCIe card ...
This has 12 SSD slots , I dont know if they are Msata or X4 M2 each ... but in case of Msata can reach 6000MB/s in Raid 0 and this needs an x8 PCIe ...
and in case of x4 M2 .. well this monster can reach 48,000 MB/s .. hence should be on X16 PCIe slot...
Sadly it seems they are using some kind of Raid chip that is off the shelve and a cheap one with X4 interface ...
My guess is that this is a X4 Raid chip connected to Msata slots .. and shame on them not using a X8 PCIe Raid chip that is already available off shelves

"~15.6 W for the 24 GB SSD"... Shouldn't it be "24 TB SSD"??vladx - Sunday, February 26, 2017 - link
Wow, just wow. Talk about innovation and pushing the limits.CaedenV - Sunday, February 26, 2017 - link
hahahaha, at 24TB that would scale out to 15.6KWKakti - Sunday, February 26, 2017 - link

Thats just a SATA raid card ,, those are nothing but Msata connected in Raid 0 nothing more ...a simple Raid card with 24 sata ports .. and sadly they went x4 Raid chip instead of X8 raid chip
