The difference between Supermicro Twin series and Dell FX2 is like a cheap version of an Android Phone and an elegant design of Apple iPhone 6 (FX in this case).
That's typically the way Dell versus Supermicro works, yep.
First of all there is no IO Aggregation of networking in Twin series. A huge upside of using FX2 with 10Gb networking already switched inside the system for all cases of server sleds. A big opex and capex savings.
A huge advantage of the Twin series is that there is no networking aggregation, thus it is a "dumb" (and hence cheap chassis). My understanding is that he FX is a little bit more like someone took the blade concept but reinvented it into a Twin form factor.
The sleds are all serviceable from the front like any rack servers. Not from the hot aisle like in case of twin series.
Supermicro Twin series have both front and rear I/O for every configuration I am aware of.
Management is truly converged for all Storage, Networking and Compute. Just give it a shot. There is no comparison.
Supermicro provides just raw hardware. Management is IPMI via the BMC. That's it. It's very bare bones. I'd love to see what Dell offers in terms of management that goes beyond this, but their PR is well night impenetrable.
A lot of PCIe slots and can be assigned depending on the workload needs to appropriate compute in case storage is used in other sleds
if you take a look at the Caesium cluster in my lab, I think you'll see it is based on the F627G2-F73PT+ Fat Twin. This comes with many PCI-E slots, and in fact two of the four nodes in Caesium currently contain nVidia GRID cards.
Storage density is industry leading with still keeping the full Hot swappability and High Availability
I have to debate this claim, sir. Pleas see Supermicro's Twin family page. They have Compute, GPU, Storage Heavy and even Hadoop-specialised members of the Twin family. I strongly doubt you're going to cram more disks per node into something than Supermicro have achieved...though I'd be quite pleased to be wrong.
Very cost effective SSD density and performance is finally in servers with still keeping 2U formfactor with full serviceability and upto 8 x 2S High end XEON CPU
Again, very standard stuff with Supermicro. Been around for ages in the Twin line.
BTW, I don't work at Dell but glad to see a very innovative and game changing product launched by a company. Getting the best of all worlds in one design- Blades, Racks and Converged Infrastructure while eliminating most of the negative aspects from those. Wait till HP, Lenovo and Supermicro types will be copying the design. But I am sure there so many patents on this by Dell that others will have to watch out!
Actually, this looks very much like Dell copied the Supermicro Fat Twin, refined it, added layers of "luxury" that can drive up the margins and basically created a solution that competes with the already fourth or fifth generation Supermicro Twin line but for companies less willing to work with bare-bones, stripped down gear.
I admit this is a required and desired niche, but I will require quite a bit of convincing to believe that it qualifies as "game changing". I say this mostly because I personally am on my second generation of Fat Twin, and I see most of the benefits you've described already. That makes this iterative, not revolutionary.
I am, however, entirely happy to be proven wrong.
