We don't think there is any latency in the environment. After reading both articles, I do see that flow-control is recommended for storage networks. <br />

What about for all <b><u>other </u></b>networks connecting to the ESXi hosts (ex. vMotion, Management, Production Server VM networks, etc.)

Always enable Flow Control, it's enabled by Default in ESXi.

Agree with hanccocka. &nbsp;The only reason you would not want to enable Flow Control is if you had QoS already in place.

I noticed that in our environment, we have an inconsistency. Some of our vSwitches connected to flow-control <b>enabled </b>ports, while other vSwitches connected to flow-control <b>disabled </b>ports on the physical switches.<br />

What is flow-control on ProCurve switches, and should it be enabled or disabled on ports connecting to VMware vSwitches?<br />

A switch is a device that filters and forwards packets of data between LAN segments. Switches operate at the data link layer or the network layer of the Open Systems Interconnection (OSI) Reference Model and therefore support any packet protocol. LANs that use switches to join segments are called switched LANs or, in the case of Ethernet networks, switched Ethernet LANs. A hub is a connection point for devices in a network. Hubs are commonly used to connect segments of a LAN. A hub contains multiple ports; when a packet arrives at one port, it is copied to the other ports so that all segments of the LAN can see all packets.

VMware, a software company founded in 1998,  was one of the first commercially successful companies to offer x86 virtualization. The storage company EMC purchased VMware in 1994. Dell Technologies acquired EMC in 2016. VMware’s parent company is now Dell Technologies.

VMware has many software products that run on desktops, Microsoft Windows, Linux, and macOS, which allows the virtualizing of the x86 architecture.  Its enterprise software hypervisor for servers, VMware vSphere Hypervisor (ESXi), is a bare-metal hypervisor that runs directly on the server hardware and does not require an additional underlying operating system.
