isilon network interfaces
Hello,
Good day to you all.
On servers or in general what I learnt is
usually when we assign a IP to a physical interface, it doesn't allows us to assign one more IP to the physical. it throws error say device already in use.
but if we create a virtual interface ( LACP / TEAMING / BONDING ) using physical interfaces, it allows us to assign multiple IP address to the virtual interface.
coming to Isilon,
How we are able to assign multiple IP to the same physical interface. does Isilon present the physical interface as a virtual or logical to the user due to which it allow as to assign multiple IP's to the same physical interface
Eg : ext1 or ext2.
in general is ext1 / ext2 or any physical interfaces listed by isilon is it a logical / virtual layer of abstraction.

ext1 and ext2 are abstractions just in the OneFS configuration, not virtual interfaces at the OS/networking level. OneFS manages IP addresses and physical interfaces based on the configurations that the admin makes for ext1/ext2. One can check the results with the ifconfig command on the OS level.
Multiple IP address per physical interface are supported by the underlying OS. Keeping in mind that OneFS is derived from FreeBSD, the FreeBSD docs should be helpful for seeing how it is done under hood; I'd look into IP "aliases" for network interfaces. But from the highlevel OneFS admin perspective, it's as usual "it just works".
