Recently I have been working on Exadata/Exalogic related stuffs, so would be putting brief details here.
Earlier I was involved in a PoC, 2 years back, would try to put practical details also from the same, at that time I did not start this blog.
Let me take you through the high Level architecture of a full rack Exadata:
In a full rack Exadata database machine, there are 8 database servers, 14 storage servers(7 cells at bottom and 7 cells at top), 3 InfiniBand Switches, 1 Cisco Switch, KVM and 2 PDUs is available.
There are 3 Infiniband Switches in a Exadata Full Rack System. Lower one is know as spine switch.
Most of the Exadata full racks have 2 leaf switches and 1 spine switch. 1/4 racks and 1/2 racks may or may not have a spine switch.
There are one Ethernet Switch in between 2 leaf infiniband switches, which has 48 ports. This is used as management network, and all the Exadata systems are plugged into this for management purpose. Ethernet switch for remote administration and monitoring of the Database Machine.
Storage Servers are also known as Cell Node, and Database Servers are also known as Compute node.
