Abstract: A storage device tray has a form factor designed to support a larger storage device, and is configured to secure a small storage device, thereby acting as an adapter between storage device sizes. The storage device tray includes a sliding mechanism configured with pegs that may couple to screw holes in the storage device. The sliding mechanism also exerts a force against the storage device to secure that storage device, and may be locked to further secure that storage device. At least one advantage of this approach is that a storage device can be coupled to a storage device tray without using screws.

Abstract: A server management switch discovers and identifies its switch ports that are connected to communication ports of baseband management controllers (BMC's) of server computers. The server management switch isolates the identified BMC-connected switch ports such that network traffic on a BMC-connected switch port is restricted to a switch port that has a connection, either directly by a link or over a server management network, to a server management computer. Network traffic on BMC-connected switch ports are monitored and controlled in various ways to further protect the BMC's from security attacks.
