We are going to replace our ageing servers. I have been quoted for 2x Dell Power Edge servers R640 and the LAN card on this server is 1Gbe Base T.
To connect the San and Host, we will be using SAS 12GBps HBA.
At the moment the core switch on our network is 1GbE and planning to connect the Host and Core switch with 1GbE copper connection
In a next 5 Months I am planning to replace my core switch and purchase a 10Gig core Switch and during that time will the ethernet card auto-negotiate between 1 and 10-gigabit on the Dell Power Edge servers R640 ?
Please suggest and any help would be great.
