This would not be good for maintainability. While I could put it in that directory, each time I get a new kernel I’d have to move it. Usually kernel modules go in /lib/modules/ uname -r but this module doesn’t seem to be tied to a particular kernel version. Running insmod is great for the first time one tries out the zdrive, but what happens after a reboot? Or perhaps I missed where this is documented by OCZ. I’m hoping that if I’ve made a mistake that someone will alert me in the comments. Loading the kernel module at bootįirst, let me say that I don’t have a lot of experience with kernel modules.

I believe the full height zdrive R4s are faster, so this is a compromise. We bought the low profile version because these drives are going into the Supermicro SC847E16-R1400LPB chassis (the subject of future posts), which have room for seven low profile cards. (Please note that this was a special case purchase–the cards didn’t meet any specific requirements we had other than that they were easily available, PCIe-SSD, and low profile.) In a previous post I mentioned how we had purchased 11 300GB OCZ Z-Drive R4 PCIe-SSD cards.
