Musing: Could We Replace Ethernet With PCIe?

February 9, 2015 By Stephen 3 Comments

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?

Why OpenStack Doesn’t Need Fibre Channel Support

May 19, 2014 By Stephen 3 Comments

Last week, J Metz penned an article entitled “Thoughts on #OpenStack and Software-Defined Storage” in which he argues (rightly) that OpenStack Cinder should take storage networks into account and also (wrongly) that it should also encompass existing protocols such as “the 11 Billion ports of Fibre Channel that currently exist as part of a holistic system of storage … [Read more...] about Why OpenStack Doesn’t Need Fibre Channel Support

Back in the day, when data was smaller and servers were machines, I/O followed a predictable pattern. Storage arrays could anticipate requests and RAID was beautiful. Then came virtualization, and with it an end to ye olde storage I/O path. Server = HBA = LUN It was a simpler time back in the 1990's. Each server had a SCSI host bus adapter (HBA) of its own. Maybe two, if … [Read more...] about The I/O Blender Part 1: Ye Olde Storage I/O Path

What Is a Blade Server?

February 18, 2012 By Stephen 13 Comments

I've been watching enterprise IT for over 20 years now, and I've seen some radical changes. In the server space, one of the biggest shifts was the form factor of the servers: From tower to rack-mount to blades. But what makes a blade server anyway? Let's consider this for a moment, as we watch another shift in progress. Blade servers are easily recognized in the data … [Read more...] about What Is a Blade Server?

For the past 33 years, I have looked in the mirror every morning and asked myself: “If today were the last day of my life, would I want to do what I am about to do today?” And whenever the answer has been “No” for too many days in a row, I know I need to change something.
