Switch supporting 16+ span/mirror instances

Are there any switches out there supporting this?

We have a situation where we need to mirror customer internet vlans in a data center, and each customer internet vlan must be mirrored to a customer-specific hardware appliance. We need to support at least 16 customer’s worth of this, and the in-place QFXes only support 4 mirror/span instances.

Our thought is to use a single QFX mirror instance sending customer vlans x,y,z out over a 20H LAG into some switch that support “lots” of span instances and then hang the hardware appliances off that switch.

Alternatively, we’re looking at e.g. Garland Network Packet Brokers.
