It’s been a while since my last post!
Today, I wanted to share with you some useful commands to extract information from Exadata (product name, serial numbers, …).

– Exadata product name

– Exadata rack serial number
– Compute nodes and cell nodes serial number
– Compute nodes and cell nodes internal component’s serial number
– Inifiniband switches serial number
– Cisco switch serial number
– PDU’s serial number
