. . . The good news, however, is that the four-core JS22 blade server does a better job competing with HP’s ProLiant rack and blade servers, at least as far as I can tell from my comparisons. If you haven’t gotten the message yet, let me repeat it again: If you are an SMB shop that does not need the computing capacity provided by the Power 570, then Big Blue really, really, really wants you to consider using the blade form factor. The economics are far more favorable for configured systems, particularly when comparing the Power 550 M50 and the JS22 blade. The gap was not nearly as large when comparing the JS12 blade and the entry Power 520 servers with i Edition software.
