They got rid of the PCI bottleneck by switching to PCIe, a bottleneck which surprised me when they designed version 1.0 of their pod. They could have gone PCIe at the time, I maintain http://blog.zorinaq.com/?e=10 http://blog.zorinaq.com/?e=10 and they were SATA controllers at the time that met their technical requirements (nr. of ports, Linux support, etc).
- SoftwareMaven 15y agoAccording to the post above, they were using three PCIe and one PCI. "In the first generation storage pod, we ran out of the faster PCIe slots and had to use one slower PCI slot, creating a bottleneck."
- mrb 15y agoI know. I meant to say they could have managed without using that PCI slot at the time (ie. using only 3 PCIe SATA HBAs, or using a mobo with 4 PCIe slots).
