White boxes crushing the traditional server market

It may not come as much of a surprise, but the latest numbers from International Data Corp. make it official: The server market is cratering. According to IDC, server vendor revenue plummeted 4.6 percent year over year the first quarter of 2017.The pain was widespread, IDC said, with market leader HPE seeing revenue drop 15.8 percent year over year to $2.9 billion. Number two vendor Dell was the only bright spot, notching 4.7 percent year-over-year growth to $2.4 billion (the growth may have come from Dell’s purchase of EMC’s data center business). But Cisco revenues fell 3 percent to $825 million, IBM dropped a whopping 34.7 percent to $745 million, and Lenovo tumbled 16.5 percent to $727 million.To read this article in full or to leave a comment, please click here

Clever RDMA Technique Delivers Distributed Memory Pooling

More databases and data stores and the applications that run atop them are moving to in-memory processing, and sometimes the memory capacity in a single big iron NUMA server isn’t enough and the latencies across a cluster of smaller nodes are too high for decent performance.

For example, server memory capacity tops out at 48 TB in the Superdome X server and at 64 TB in the UV 300 server from Hewlett Packard Enterprise using NUMA architectures. HPE’s latest iteration of the The Machine packs 160 TB of shared memory capacity across its nodes, and has an early version of …

GE’s Predix wants to help the industrial IoT shine

GE has always had technology as a core part of its offering. After all, you don’t build wind turbines, jet engines and gas plants without leveraging technology. But in recent years, the company has moved from being an industrial company that uses technology to an outright vendor of technology solutions.A core part of this approach is by powering what GE calls the Industrial IoT, that is all the connected devices that are used in industrial settings of every kind. Predix is GE’s platform for the industrial IoT, and it promises to connect machines, data and people to drive results. Predix offers a single platform based in the cloud that can reconcile all the disparate data feeds and information streams pouring out of the industrial IoT.To read this article in full or to leave a comment, please click here

Consumer IoT could outpace industrial IoT

Both Gartner and Tech Insider agree, the Internet of Things (IoT) will be a major tech category, predicting  20.4 billion units and 23.9 billion devices, respectively, by 2020.They disagree, however, about where those devices will go. Gartner says two-thirds of the devices will land in consumer applications. Tech Insider says over three-fourths will land in government and business applications.+ Also on Network World: 5 things to think about for industrial IoT readiness + Why is there such a big difference in forecasts? Which forecaster’s crystal ball is less occluded? Gartner’s forecasts depend on more stable, smaller IoT consumer islands, while Tech Insider’s forecasts depend on large clouds often built on evolving technologies.To read this article in full or to leave a comment, please click here

Remote unlocking of LUKS-encrypted root in Ubuntu/Debian

This Post is now outdated. Particularly the said bug is finally fixed.

Updated version is available HERE

Unfortunately the bug-fixed version of cryptsetup package, caused incompatibilities with the previous version of the workaround. If you see this message when remotely unlocking your server:
“/bin/cryptroot-unlock: line 192: 2: parameter not set“

Run this command instead to boot your system:
sed 's/print $1, $5/print $1, $3/' /bin/cryptroot-unlock > /tmp/cryptroot-unlock; ash /tmp/cryptroot-unlock

And then remove the workaround and rebuild initramfs:
sudo sh -c 'rm /etc/initramfs-tools/hooks/zz-busybox-initramfs-fix && update-initramfs -u'

Thanks to Gabriel Burkholder for reporting this

Not so long ago, remote unlocking of a LUKS-encrypted root partition was difficult to setup. While essential for headless servers, all required steps needed to be done manually and compatibility was a concern.

Luckily, it is much simpler to do so in recent versions of Ubuntu/Debian. Unlocking an encrypted root remotely should be as simple as installing a single package… We’ll see about that in a moment.

I am not going to cover the required steps for setting up LUKS/LVM here. That information is widely available on the net and is only a search a way. Instead, I’m going to do a quick review of the Continue reading

RPM Post-Upgrade Scripts

Something different today: Here’s something I learnt about RPM package management, and post-upgrade scripts. It turns out that they don’t work the way I thought they did. Post-uninstall commands are called on both uninstall and upgrade. For my own reference as much as anyone’s here some info about it, and how to deal with it.

RPM Package Management

RPM is a Linux package management system. It is a way of distributing and managing applications installed on Linux systems. Packages get distributed as .rpm files. These contain the application binaries, configuration files, and application metadata such as dependencies. They can also contain scripts to run pre- and post- installations, upgrades and removal.

Using package management systems is a vast improvement over distributing source code, or requiring users to manually copy files around and run scripts themselves.

There is some effort required to get the spec files used to create packages. But once it has been set up, it is easy to create new versions of packages, and distribute them to users. System administrators can easily check which version they’re running, check what new versions are available, and upgrade.

We use RPMs to distribute StackStorm packages for RHEL/CentOS systems. Similarly, we distribute Continue reading
