[Neil Goodman] “For example, we all have Aja cards, need a place to stick those cards and our TD wont invest in anything without a roadmap for upgrades and expandability so we can future proof. “
When we moved to a nearly all thunderbolt infrastructure, we kept our pcie fiber cards and AJA pcie cards. They still work, many years later. Much longer than expected.
When we ditched all forms of tape capture/layoff, and all the infrastructure of THAT (patch bays, most AV Routing, and granted we are small, not large, facility) we switched to thunderbolt a/v output devices (but still have our PCIe cards in thunderbolt pcie chassis).
So future proofing in this sense, is more like legacy dragging. So far, Thunderbolt hasn’t stopped us from dragging a legacy, it has opened up more connectivity between disparate machines and devices (laptops/iMacs/whatevers hooked to fiber that was impossible before, etc).
It is a big decision to decide which legacy to drag, including the the new legacy a recent purchase inevitably represents.
