The USB 3.0 Solid State Drive (SSD) port on the rear panel of the switch supports an optional 120GB USB 3.0 SSD storage device (SSD-120G). SSD-120G provides an extra 120GB of storage for application hosting. Applications can be hosted in KVM (Kernel-based Virtual Machines), LXC (Linux Containers), or Docker containers. SSD-120G can also be used to save packet captures, trace logs generated by the operating system, Graceful Insertion and Removal (GIR) snapshots and third-party applications. SSD-120G can be used simultaneously as a general-purpose storage device and as an app hosting device. You must use only Cisco USB drives; non-Cisco USB drives are not supported.
SSD-120G is enabled with S.M.A.R.T (Self-Monitoring, Analysis and Reporting Technology) functionality to monitor endurance, predict wear-out and carry out various self-tests.
