Datacenter racking, power solutions

I have to say, we've been very fond with the hardware we've gotten after choosing SMC to provide server racking for us. They custom build everything (and still have very reasonable choices), and you can work with them to receive engineering drawings of the racks of your choice before you order them. In our case, we picked a nice deep rack with lots of space on the left for zero-u mounting of PDUs.

We also (as they have been partered with SMC) switched to putting in 60A 3-phase power to every rack. We've got an Aphel front-end PDU for each rach, which we then cross-connect with the neighboring rack for the load. (we install all racks in pairs now, side-by-side)

The unfortunate part of this process is actually getting the equipment. We've gone through the process to order nice equipment, then had horrific times actually having it get to our site. 99% of the time, the problem wasn't with SMC, but with the PDU supplier. In the case of our last order, they had been purchased by another company, who had come in and discontinued the slave 15A PDUs we were using... unfortunately, this happened while we were waiting for shipment.

Well, we received the racks right quick. Took us 6 weeks to get our front-end PDUs. We're still waiting for delivery on some slave PDUs that they had to substitute in.

On a good note, the newly substituted slave PDUs will come with custom-made mounting brackets for our rack and instructions on how to install them. (they have a different form-factor than the others we had been getting)
