Isilon MIBs

Isilon (later EMC/Dell EMC) makes the OneFS scale-out NAS clustered storage platform, and its two MIBs here cover that product end to end: ISILON-MIB for polled cluster-wide health (node counts online/offline, internal filesystem and client-network throughput, cluster identity) and ISILON-TRAP-MIB for the companion fault notifications (disk/filesystem failures, cluster membership changes, storage-quota threshold breaches). Recurring subject matter is cluster redundancy and capacity status -- whether all configured nodes are actually online, and whether a quota or filesystem condition needs attention -- reflecting the scale-out architecture where node loss is the primary failure mode to watch for. If you run an Isilon/OneFS cluster, this is where both the steady-state polling objects and the event-driven trap definitions live, designed to be used together rather than either module alone.
