Now that I finally tested ES40 write some notes about these machines.

Triggered that ES40 should 'just work by': gallatin

+
+      <para>Memory is divided in 4 memory arrays which each contain 
+      a set of 4 SDRAM DIMMs. Each DIMM is 72 bit wide and of the 100MHz
+      speed variant. An array can contain 2 sets, so 8 DIMMs max per array.
+      The DIMMs live on Memory Mother Boards (MMBs). There are 2 MMB models,
+      with 4 and 8 DIMM sockets respectively. Each MMB provides half of the
+      256 bit memory bus width to the CPUs. 
+      Given the myriad options for the memory configuration it is advisable 
+      to check the system documentation for the optimum memory 
+      configuration.</para>
+
+      <para>Dependent on the model variation the ES40 has 6 or 10 64 bit PCI
+      slots. This is basically just means the same backplane with less

+
+      <para>ES40 has the same RMC remote power control as DS10 and DS20. 
+      See the description of the RMC in the DS10 section of this document.
+      Most variations of ES40 have multiple power supplies, allowing
+      for N+1 redundancy. When installing CPU cards you must unplug all
+      power cords, the CPU cards receive standby power from the power
+      supplies. Maximum memory configurations need more than the default
+      number of powersupplies.</para>
