Hey everyone, this is my first post here. I've been lurking around for a few weeks, and I'm looking to build my first home lab with esxi and virtualizing freeNAS to manage my datastores.
I was reading the following thread, https://forums.freenas.org/index.ph...csi-vs-nfs-performance-testing-results.46553/, and seeing a few others like it with a 10 Gbps ethernet card being used. Is this simply to supply clients on your network with 10 Gbps transfer rates, or is an ethernet card rated at that speed required since iSCSI is wrapping scsi commands in TCP/IP and must by handled by an ethernet card? IE is your ethernet card going to cap your transfer speeds in an entirely virtualized test environment (e.g. VM freeNAS)? I thought in a virtual environment you could create a virtual switch and your read/write speeds would be more/less based on the CPU/RAM/SAS or SATA drives you have connected.
When using iSCSI in a virtual environment (ESXi specifically), are you constrained by your ethernet card (1 Gbps vs 10 Gpbs), even if all of your OS's and hard drives are within the same physical "Box," are all virtualized, and connected by a virtual switch? From the latter replies in the thread that doesn't seem to be the case as @soulburn had a baremetal freeNAS but handled esxi's datastores.
