Hi Bob, thanks for your interest! Hopefully we can connect the dots and get you set up with devices to test. We have several products that can be used to create a RACHEL-Pi server. Which one(s) to ultimately use may depend on individual deployment projects- the priorities in terms of cost, #simultaneous clients, power consumption, physical environment, etc.
You can look at our current products here: https://www.wdc.com/products/wdlabs.html . We have more coming soon.
The product categories to focus on are:
PiDrives: USB disk drives optimized for R-Pi. Attach to R-Pi and use the software above to install RACHEL-Pi and RACHEL modules to the PiDrive.
Enclosure kits for R-Pi + PiDrive.
PiDrive Compute Centre: full computer kit including Pi3, PiDrive, enclosure, wireless KB/M, cabling, power supply, preloaded SDcard. Bring your own HDMI monitor and cable.
PiDrive Node Zero: PiZero integrated with PiDrive into a compact, low-cost, low-power server.
Our on-line store doesn’t currently reach SA, but we’re collaborating with several Pi distributors that may be able to ship there (The Pi Hut, Pi Supply, BuyaPi; more to be added). We could also set up an arrangement with a local distributor in SA that carries R-Pi products.
We’re located in Irvine, California.
After reviewing our products, can you make a proposal on what to send for beta test (products and quantites)? We can try different kits/configurations and see what works best, if you can manage it.
