Servers/Hardware

  • I recently mentioned on Twitter that I was considering building out a new Linux PC to replace my aging Mac Pro (it’s a 2012 model, so going on 9 years old). Joe Utter shared with me his new lab build information, and now I’m sharing it with all of you. Sharing is caring, you know.

Save the Date! Next Docker Community All Hands

We’re excited to announce that our next Community All Hands will be on March 11th, 2021. This quarterly event is a unique opportunity for Docker staff and the broader Docker community to come together for live company updates, product updates, demos, community shout-outs and Q&A. We had more than 1,500 attendees for our last all-hands and we hope to double that this time.  

This all-hands will be particularly special because it will coincide with none other than….you guessed it…Docker’s 8th birthday! For this “birthday edition,” we’re going to make the event extra special.

We’ll start by extending the format from 1 hour to 3 hours to pack in more Docker goodness. The main piece of feedback we got from our last all hands was that it was way too short. We had too much content that we tried to squeeze into 60 minutes. This longer format will give us plenty of time to cover everything we need to cover and let presenters catch their breath ?

Another new feature of this all-hands will be integrated chat and multi-casting made possible by a new innovative video conferencing platform we’ll be using. This will give us the opportunity to present content Continue reading

HPE intros SSD replacements for 10K RPM HDD server drives

There was once a time when hard drives that spun at 10,000 and 15,000 RPMs were considered fast storage. Then came the SSD and blew that all away. But there are some old servers out there still using them, and they could use a more modern approach.HPE has announced an SSD replacement option for SATA-connected disk drives in its Apollo, ProLiant and Synergy servers called Very Read-Optimized (VRO). These 2.5-inch and 3.5-inch SSDs use SATA interfaces and are plug-in replacements for the drives in the servers.HPE claimed in a Community Experts blog post this week that the drives will deliver better TCO than 10,000 RPM HDDs, although really, that's not a hard claim to make. Based on HPE's own testing, you can get 70,000 read IOPS on an HPE SATA VRO SSD compared to 400 IOPS on the fastest HPE 10K HDD. It's not even close. HPE argues that the upgrade pays for itself. It says the SSDs are up to three times more energy efficient than the 10K drives.To read this article in full, please click here

Automating mixed Red Hat Enterprise Linux and Windows Environments

For a system administrator, a perfect world would consist of just one type of server that we needed to support and just one tool to do that work. Unfortunately, we don’t live in an ideal world. Many system admins are required to manage day to day operations of very different servers with different operating systems. The complexity gets magnified when you start looking for tools to manage these distinct systems. Looking at how to automate these systems could lead you down a path of one automation tool per OS type. But why? When you can have one central automation platform that can be used for all servers. In this example, we are going to look at managing Red Hat Enterprise Linux (RHEL) and Windows servers in one data center by the same group of system administrators. While we are going to cover the use case of managing web servers on both RHEL and Windows in some technical details, be aware that this method can be used for almost any typical operational tasks. 

 

Scenario: Managing the web service on RHEL and Windows

Repost: On the Importance of Line-Rate Switching of Small Packets

I made a flippant remark in a blog comment…

While it’s academically stimulating to think about forwarding small packets (and applicable to large-scale VoIP networks), most environments don’t have to deal with those. Looks like it’s such a non-issue that I couldn’t find recent data; in the good old days ~50% of the packets were 1500 byte long.

… and Minh Ha (by now a regular contributor to my blog) quickly set me straight with a lengthy comment that’s too good to be hidden somewhere at the bottom of a page. Here it is (slightly edited). Also, you might want to read other comments to the original blog post for context.

Docker Index Shows Continued Massive Developer Adoption and Activity to Build and Share Apps with Docker

It’s been one year since we started publishing the Docker Index (stats, trends and analysis from developers and dev teams based on anonymized data from millions of Docker users). At that time we saw how Docker was being used at an incredible scale to power application building globally. Today we are excited to share the latest edition of the Docker Index, this time with some yearly and quarterly comparisons. 

Every time we pull these user stats, we are blown away by the sheer volume and continued growth in activity happening across the Docker developer community. It’s clear to see that collaborative application development platforms are the foundation for developers who want to build, share, and run modern apps. We are also thrilled to see this type of growth more than one year after refocusing Docker on making developers’ lives easier. The Docker community has stayed with us and continues to grow at a tremendous pace, giving us very encouraging signals about the path that Docker is taking. 

To begin, there has now been a total of 318 billion all time pulls on Docker Hub, an increase of 145% year-over-year. That’s right, the total number of pulls has increased Continue reading
