5 host network configurations for MLAG

Host network configurations for MultiChassis Link Aggregation (MLAG, also referred to as dual-attach or ‘high availability’) can vary from host OS to host OS, even amongst Linux distributions. The most recommended and robust method is to use Link Aggregation Control Protocol (LACP), which is supported on most host operating systems natively. Host bonds or bonding refers to a variety of bonding methods, but for the purpose of this article it will refer to LACP bonds. The terms etherchannel, link aggregation group (LAG), NIC teaming, port-channel and bond can be used interchangeably to refer to LACP depending on the vendor’s nomenclature. For the sake of simplicity, we will just call it bonds or bonding. This post will take your through the steps for host network configurations for MLAG across five different operating systems.

Why LACP? LACP is a IEEE standard that has been available since 2000 known as 802.3ad. This makes a highly interoperable standards approach to bonding that can work across many network vendors and host operating systems. LACP is superior to static configuration (also referred to bond-mode ON) because there is a control protocol keeping the bond active. This means failover is predictable and automatic. This is also Continue reading

Worth Reading: Hacking through the random number generator

Late Last Autumn, a Russian mathematician and programmer named Alex decided he’d had enough of running his eight-year-old business. Though his St. Petersburg firm was thriving, he’d grown weary of dealing with payroll, hiring, and management headaches. He pined for the days when he could devote himself solely to tinkering with code, his primary passion. The time had come for an exit strategy. —Brendon Koerner @ Wired

Data center provider Equinix bets big on fuel cells

Data center provider Equinix is making a big bet on fuel cells to power its facilities by installing natural gas-powered fuel cells at 12 of its U.S. data centers. It’s part of a push for the firm to be 100% reliant on renewable fuels, and it could set an example for other data centers in power management.Equinix uses fuel cells developed by Bloom Energy, a leader in the data center energy market that has been profiled by 60 Minutes and whose giant “batteries” are installed at data centers run by eBay, Apple, NTT, CenturyLink and Verizon.To read this article in full or to leave a comment, please click here

Worth Reading: Why you should document first

Programmers and project managers sometimes think the phrase “doc-driven development” means putting a lot of comments in code or working closely with doc writers as development happens. That’s because it’s hard to imagine how development can possibly happen after documentation, because surely documentation can’t happen until there’s something to actually document. —Seth Kenlon @ Opensource
