ما معنى Out-of-band management network, direct-attach cable؟

يُعرف أيضًا باسم: out-of-band management network · direct-attach cable

Definition 2.8 Networks, Hardware and Trading Infrastructure · الفصل 2 — Switches and Layer-1 Devices

An out-of-band management network is a separate network, with its own switches and links, over which a firm administers its devices and servers, so that configuration, monitoring and remote access never share a port or a queue with trading traffic, and still work when the trading network does not. A direct-attach cable is a copper cable assembly with the transceivers built into its ends, used for short links within a rack.

The layer-1 design of the chapter’s cage. Each venue line goes through a tap to its own fan-out, which copies it to both servers; each server’s orders go through two multiplexers to two order-entry handoffs. Every handoff is tapped (one tap’s copy drawn); management is out of band and not drawn. Removing any single device or cable leaves every server with a line and an order path.
