When I think of a NAS, I generally think of it in terms of a storage device. Then again, that kind of ignores the whole “network-attached” part!
That may seem like a minor point, but not when it comes to measuring data and transfer speeds. Confusing storage bytes with networking bits doesn’t just cause confusion, it might have implications for what is actually possible with your NAS. Tony Bourke put together an excellent primer to straighten everything out.
Tony Bourke of The Data Center Overlords comments: In my last article, I talked about how Fibre Channel, as a technology, has probably peaked. It’s not dead, but I think we’re seeing the beginning of a slow decline. Fibre Channel’s long goodbye is caused by a number of factors (that mostly aren’t related to Fibre […]
Eric Smith of Brass Tacks comments: Although this blog post isn’t an April fool’s joke, I do greatly appreciate them when they are done well. As a result I’m slightly in awe of the amount of thought Tony Bourke has put into his last three (2013, 2014 and 2015). Truth be told, I’m actually kind of honored […]
Tony Bourke of The Data Center Overlords comments: On my way back from South America, I was pointed to a bake-off/performance test commissioned by Brocade and performed by a company called Evaluator Group. It compared the performance of edge FCoE (non-multi-hop FCoE) to native 16 Gbit FC. The FCoE test was done on a Cisco […]
Tony Bourke from The Data Center Overlords comments: I got in a conversation today on Twitter, talking about SDN/SDF (software defined forwarding), which is a new term I totally made up which I use to describe the programmatic and centralized control of forwarding tables on switches and multi-layer switches. The comment was made that OpenFlow […]
Tony Bourke of The Data Center Overlords comments: There are very few technologies in that data center that have had as significant of an impact of VMware’s vMotion. It allowed us to de-couple operating system and server operations. We could maintain, update, and upgrade the underlying compute layer without disturbing the VMs they ran on. […]
Tony Bourke of The Data Center Overlords comments: In a previous article, I discussed the somewhat pedantic question: “What’s the difference between EtherChannel and port channel?” The answer, as it turns out, is none. EtherChannel is mostly an IOS term, and port channel is mostly an NXOS term. But either is correct. But I did […]
Tony Bourke from The Data Center Overlords comments: In the networking world, you’ve no doubt heard the terms EtherChannel, port channel, LAG, MLAG, etc. These of course refer to taking multiple Ethernet connections and treating them as a single link. But one of the more confusing aspects I’ve run into is what’s the difference, if […]
