MC_SERVICES_P9

   (Alpha only) MC_SERVICES_P9 specifies the number of initial
   entries in a single channel's free queue. The maximum value is
   2048, and the minimum value is 10.

   Note that MC_SERVICES_P9 is not a dynamic parameter; you must
   reboot the system after each change for that change to take
   effect.

   The default value is 150. VSI recommends that this value not be
   changed.

   The value of MC_SERVICES_P9 must be the same on all nodes
   connected by MEMORY CHANNEL.
