Inside EMC 3-20

EMC guys came over to our office the other day and claim that one of the SP is faulty even though there were no amber lights indicating the fault.

Unisys was the appointed service vendor over here and during the hardware replacement, I managed to take a few snapshots of the unit.

 

As seen from the picture above, the iSCSI module is connected to box via a daughterboard.  I supposed the CPU is right underneath the big cooper heat-sink but I haven’t got a chance to remove the heat-sink to reveal the CPU make and model.

One thing for sure, this thing uses 2 x 1Gb DDR2 ECC rams and with 2 more slots to spare.  These rams will be used for both the Read/Write cache and adding in extras will boost the performance significantly.  Having said that, I’m beginning to wonder the difference between the CX3-20 and the Top-Of-The range model CX3-80 which is sharing the same chassis; izzit just the ram or what?
