For using the <( ) and >( ) process substitution, the OS must support Unix devices, and bash must be compiled to utilize it.
Obviously not true for your OS and bash.?
Code:
uname -sr
bash --version

The following pipes stderr (descriptor 2) to sed. But a pipe works with stdout (descriptor 1) only. Therfore, it swaps stdin and stdout before the pipe, and afterwards swaps them back.
Code:
#!/bin/bash
for server in server1 server2
do
  {
  ssh -x "$server" '
    echo "hello I am on `hostname`"
    sudo yum update infolist
  '  3>&2 2>&1 1>&3 | sed "s/^/$server: /" 
  } 3>&2 2>&1 1>&3
done 2>stderr
