Yes, various models of the CloudLine boxes do have ECC, as do the 
Microsoft Open CloudServer blade designs.

The HP CL1100 box has 8 slots for DDR4 RDIMM or LRDIMM registered 
memory.   The HP CL2100 and CL2200 boxes have 16 slots for DDR4 RDIMM 
or LRDIMM.

CL3100 doesn't, and lists four slots for DDR3 UDIMM support.

There's smoke and a great splattering of marketing from HP on 
CloudLine, but not much actual bacon.  You have to look elsewhere to 
get actual specs.

Specs on some of the Microsoft designs are available at 
<http://www.opencompute.org/wiki/Server/SpecsAndDesigns>, and the Open 
CloudServer blades are decently gonzo designs, and do have ECC; the 
specs that are most obviously available indicate Xeon E5-2600 v3 blades 
with 16 slots of DDR4 RDIMM (DDR4-600, -1866 or -2133) and support for 
16 and 32 GB RDIMM sizes.

There are also Open Compute high-availability server designs available, 
if that's your target.

As for the HP CloudLine / Foxconn stuff, oddly, the best available 
descriptions are elsewhere, and not on the HP CloudLine site.

HP specs on the CL boxes, and general CL, SL and Apollo product 
positioning, and yes, I'm sure some folks here will want to see VMS on 
the Aquarius^WApollo boxes, too:

For those that might need it, a DIMM decoder
