Re: Exadata V2 Compute Node 10GigE PCI card installation

Please share the results of your findings with us, if you see any change in airflow path. I would like to know how much truth is their in support's statement regarding airflow.

This ranges from replacing unused 10GbE cards with fibrechannel HBAs, installing additional hard drives in the unused SAS slots on the front of compute nodes, adding memory to the V2 systems (you can purchase a memory upgrade kit for the X2-2 systems), or even installing non-Exadata servers in the physical Exadata rack.  I'll have to crack open our V2 and X2-2 compute nodes and compare the airflow paths today.

Currently since V2 compute nodes have only 40Gb/s infiniband and 1GigE cards in them, we can only connect over 1Gb/s speed to NAS filer. Oracle is quoting ridiculous price (even thought of mention the range makes me little unhappy) for their ZFS Storage appliance which have infiniband connectivity.
