Once upon a time there was Ethernet. Every half decade or so, the industry got together and worked out a faster version. Sometimes they didn't totally agree, but a standard emerged at 10x the speed of the previous version. Throw all that out the window: Faster Ethernet is coming, and it's going to be weird! Although it looks like a simple network Channel, Ethernet is … [Read more...] about Faster Ethernet Gets Weird
As I mentioned in my previous post about Raspberry Pi power monitoring, I recently built a VMware vSphere "datacenter" from three Intel NUC mini PC's. One limit of the NUC is that it has just one Ethernet port. But there's a Mini PCIe slot inside the fourth-generation NUC that can be used to add a second Ethernet NIC! Here's my story. A Bit About the Intel NUC … [Read more...] about Adding a Second Ethernet Port to an Intel NUC via Mini PCIe
Greg "EtherealMind" Ferro recently "mused" that it might be a good idea to replace PCI Express (PCIe) inside servers or rack-scale infrastructure with Ethernet. But this seems to be the exact opposite of the direction the industry is headed. Rather than replacing PCIe with Ethernet, companies like Intel seem set on replacing short-range Ethernet (in rack-scale systems) with … [Read more...] about Musing: Could We Replace Ethernet With PCIe?
On reading my thoughts about the evolution of enterprise storage, culminating in what I called “The Rack Endgame” where a rack of storage, networking, and compute becomes a the basic entity of the datacenter, many pointed out that this looks an awful lot like the Facebook-led Open Compute Project (OCP). This is entirely intentional. But OCP is simply one expression of this new … [Read more...] about The Rack Endgame: Open Compute Project
Every day, I'm briefed by another company with a range of products from entry-level to high-end. And every day I try to figure out their naming scheme: It seems most IT vendors follow the naming schemes of car companies, but few use the same naming system! As Micron explained the logic behind their three SSD lines (e, m, and h for entry-level, midrange, and … [Read more...] about What’s In A Name? And Which Product Is Better?
