I do not have direct experience with big datacenters, but it is said that the peak of popularity of "blades" was some 5-7 years ago and now they are being replaced mostly by "sleds", which are supposed to be cheaper and simpler.

You can see examples of sleds, either in the OpenCompute specifications or at most vendors, e.g. at Dell, HPE, Supermicro &c.
