So I am about to pull the trigger on an overall editorial system upgrade for 3 FCP edit bays that will include a DaVinci Resolve panel and a cubic expander for our grading suite.
We're moving from direct-attached XRAIDS to a StorNext SAN, with a 20 port 4GB Fiber Channel Switch and 2 Rorke Galaxy HDX3 32 TB RAIDS with SAS dual controllers.
The Resolve room will be run on a new 12 core MacPro with 24G of RAM, and the ATI HD 5770 as the GUI card for Resolve.
We are going with the CUBIX Expander Rackmount 6 which can add six to twelve PCI Express (PCIe) slots to one, two or three computers. This allows us to configure it as three independent Xpander units order to provide flexibility for expanding either our Resolve suite and/or the other bays.
For Resolve we are going to start with two nVidia 4000's, a rocket and Kona 3G card in one of the expansion units, leaving us two open expansion units to either add more 4000's or say, make edit B a Smoke suite, or add a Rocket for dailies using RedCine.
For monitoring we are using a Panasonic V25 54" panel with our existing 14" Ikegami color critical CRTs as a secondary reference (which we may or may not keep).
Our understanding from our system integrator and BMD is that they have tested the Rackmount 6 configuration with two 4000's and we should be able to do 4K real time grading (at least in a half-debayer), but I can't yet get a clear picture on how many nodes etc...
But for color correction, color depth is far more important than resolution, so if we are grading 4K or 5K r3d's at half debayer we should be good.
Backup will be via a Quantum LTO-5 superloader.
Any feedback, comments or suggestions welcome.
