Cyclone PCIe Expander
I just wanted to share with everyone looking at Davinci on Mac and wondering how to fit all the PCIe cards in a system, my experience with the Cyclone 600-2707 PCIe expander.
https://www.cyclone.com/products/expansion_systems/600-2707.phpIt is great.
Uses one 16x v2 PCIe slot and provides three 16x v2 slots and two 8x v2 slots. If you set it up right you can fill it with cards and not use more than the 16 v2 lanes of bandwidth it has with the host system.
I haven’t used it with Resolve yet, but it seems like it will be perfect for that.
So far the only problem I have had is with the Atto R60F raid card. Seems like none of the ATTO 6G cards work with it, but the 3G cards do.
I have mine in a different enclosure with 10 drive trays and an LTO4.
For Resolve with the Cyclone, I would consider this config:
Mac Pro
Slot 1: GPU (GTX285)
Slot 2: Cyclone
Slot 3: Blackmagic (its only a 4x card)
Slot 4:Cyclone
Slot 1: Atto Raid (x8 v1 card, only 3G cards work right now)
Slot 2: Red Rocket (x8 v1 card)
Slot 3: Secondary Video card for display
Slot 4:
Slot 5:And that leaves room for three more cards. Plus the enclosure for the Cyclone can be set up to hold several drives to connect internally to your Atto raid card. And all your cards are getting their full bandwidth.
Price isn’t bad ($2500) considering I have 10 drives in the enclosure and an LTO4 and I could have easily spent have the cost of the Cyclone just on enclosures for those.

I’ve also used this enclosure with the Mac and RedRocket and it works well.
Dustin, where did you get the enclosure for 10 drives?Adam

This is the enclosure I got:

And I got these to hold the drives:

Also, replaced all the default fans with much quieter ones. The fans that come with the Cyclone are insanely loud. I think an engineer might have spent time seeing just how loud he could make an 80mm fan.
Mahalo,

Which fans did you replace them with?

I use a lot of the SilenX fans:

I also use fans in the PCIe cooling slots like this:
