We are an Aerohive shop. We keep a set of current models for deployment that serves as spare stock. With that said, based on the average turnaround time for RMA units, we’ve probably only had as many as 2 of a given model in use as a replacement for a failed unit at the same time once or twice in the past 4 years. It would really depend on the average failure rate for your particular model and your deployment size. I would feel very confident with 1% with almost any product line out there, and would probably consider anything over 1% as overkill.

Do you keep a percentage of each model of AP in inventory, and what is your reasoning? Storms? Last minute/emergency wireless coverage needs? What percentage of your live gear do you keep as offline inventory? (100 live APs with 1 inventory AP = 1% offline inventory). With Xirrus, we had an offline inventory of more than 10% of live inventory. We kept that inventory to cover the high failure rate of the equipment, the incidence of hurricanes and lightning strikes in our area, the broad range of AP models on campus, and last minute large events in low coverage areas. We are evaluating the minimum offline inventory for our new Aruba gear as we finish up the vendor switch. I have been thinking 1-2%, but I want to see what you guys do first, and why.
