Stretching GPU Database Performance With Flash Arrays

For the past decade, flash has been used as a kind of storage accelerator, sprinkled into systems here and crammed into bigger chunks there, often with hierarchical tiering software to make it all work as a go-between that sits between slower storage (or sometimes no other tier of storage) and either CPU DRAM or GPU HBM or GDDR memory. …

Webinar: How the Internet Really Works

I’m doing a live webinar at Safari Books Online on March 15thabout the operation of the ‘net—

This live training will provide an overview of the systems, providers, and standards bodies important to the operation of the global Internet, including the Domain Name System (DNS), the routing and transport systems, standards bodies, and registrars.

Upgrade Scripts

We need to do “upgrades in the network” is one of those phrases that chills the bones of all IT engineers. Upgrades don’t have to be so painful and in this blog, we’re going to discuss the upgrade process recommended by Cumulus and leave you with some example automation to make the process as efficient as possible.

Upgrades are necessary to maintain stable and secure code but bring the risk of new bugs and sustained outages due to unforeseen circumstances, and they’re generally not very easy to perform. Anyone who has worked network operations knows that upgrade windows could run as quickly as an hour or as long as all night (and maybe for the next three nights). Even as I write this I am remembering experiences from upgrade windows of old where things did not go according to plan. But before we get into the specifics of the upgrade process with Cumulus, it is worth discussing why upgrades in the network are so fraught with peril.

DISCLAIMER: Rant Incoming

The biggest impediment to network upgrades is complexity. When we say complexity we mean the conscious choice to add complexity into the design of the network that most folks undertake Continue reading

Linux security: Cmd provides visibility, control over user activity

There's a new Linux security tool you should be aware of — Cmd (pronounced "see em dee") dramatically modifies the kind of control that can be exercised over Linux users. It reaches way beyond the traditional configuration of user privileges and takes an active role in monitoring and controlling the commands that users are able to run on Linux systems.Provided by a company of the same name, Cmd focuses on cloud usage. Given the increasing number of applications being migrated into cloud environments that rely on Linux, gaps in the available tools make it difficult to adequately enforce required security. However, Cmd can also be used to manage and protect on-premises systems.To read this article in full, please click here

BrandPost: How edge computing will bring business to the next level

What do embedded sensors, ecommerce sites, social media platforms, and streaming services have in common? They all produce vast volumes of data, much of which travels across the internet. In fact, Cisco estimates global IP traffic will grow to 3.3 zettabytes annually by 2021 – up three times compared to internet traffic in 2017.For many businesses, these data packets represent treasure troves of actionable information, from customers’ buying preferences to new market trends. But as the volume and velocity of data increases, so too does the inefficiency of transmitting all this information to a cloud or data center for processing.To read this article in full, please click here

BrandPost: How is 802.11ax different than the previous wireless standards?

Most networking groups have a wireless guy, maybe two – you might be that person. For years, the rest of the campus network group hasn’t really had to think about what they plugged into the network. Give them a gig port, PoE, probably set up a VLAN and that’s it: wireless sorted.Because when it all came down to it, it didn’t matter how many wireless users connected to the access point because only one device, the client or the access point, could transmit at one time. What’s more, a single wireless client is not going to tax a gig port. In fact, the more clients there are on an AP, the less traffic ends up on the wire since they spend more time trying to get a timeslot to transmit, like the seagulls in “Finding Nemo” yelling “Mine, mine, mine.”To read this article in full, please click here

BrandPost: The Network Gets Personal

In a competitive environment, with so much emphasis on the need for communications service providers (CSPs) to offer more personalized services to increase customer loyalty, the network plays a crucial role, explains Kent McNeil, Vice President of Software for Blue Planet. While the connection between network infrastructure and the customer relationship isn’t obvious, it is actually what drives personalization of services and competitive edge.Enhancing the customer experience and lowering churn rates are key objectives for CSPs; however, an influx of competition is challenging customer loyalty. Equally, leading-edge technologies, from devices to cloud, have created new visions for consumers and enterprises. This has significantly changed customer demands, as well as expectations about how those requirements are fulfilled. Customers expect more personalized services, with tailored offers and ease-of-use.To read this article in full, please click here
