Ubuntu follows the release cycle of the new version twice a year, with one released in April and the other released in October, accompanied by many important improvements. The 2020 version will be Ubuntu 20.04 with the Focal Fossa identifier, which is expected to be released to global users starting April 23 next year.The codename of the official Ubuntu updates is chosen in alphabetical order, and is made up of 2 words, the first word is adjective and the second word will be noun, which is specific here as a certain animal is in danger of extinction, or sometimes mythical creatures such as Unicorns or Werewolfs (Wolves).

focalfossa

We have the Focala version of April 2020 with the word ‘Focal’ meaning ‘necessary’ and the Fossa is a carnivore that looks like a lynx, which can only be seen now. in Madagascar.

This is an interesting and unique code naming that only Ubuntu applies, giving users a sense of both curiosity and memorable.

However, the code names of Ubuntu releases sometimes reveal some of the characteristics of the releases. Ubuntu 20.04 will not only be an important release (with long term service), but also contain the strengths commonly found in Fossa species such as flexibility, agility and dominance.

In short, Ubuntu 20.04 is the LTS version, so the main focus of this release will be to bring stability and reliability to users. Focal Fossa came with lots of improvements, bug fixes, and especially new features. Let’s see some of them!

 

New Features in 20.04 LTS

 

Installer

The live server installer is now the preferred media to install Ubuntu Server on all architectures.

Besides architecture support, the main user visible new features are support for automated installs and being able to install the bootloader to multiple disks (for a more resilient system).

Installer

Installer

There have been many other fixes under the hood to make using encryption easier, better support installing to multipath disks, more reliable installation onto disks that have been used in various ways and allowing failures to be reported more usefully.

Linux Kernel

Ubuntu 20.04 LTS is based on the long-term supported Linux release series 5.4. Notable features and enhancements in 5.4 since 5.3 include:

  • Support for new hardware including Intel Comet Lake CPUs and initial Tiger Lake platforms, AMD Navi 12 and 14 GPUs, Arcturus and Renoir APUs along with Navi 12 + Arcturus power features.
  • Support has been added for the exFAT filesystem, virtio-fs for sharing filesystems with virtualized guests and fs-verity for detecting file modifications.
  • Built in support for the WireGuard VPN.
  • Enablement of lockdown in integrity mode.

Other notable kernel updates to 5.4 since version 4.15 released in 18.04 LTS includes support for AMD Rome CPUs, Radeon RX Vega M and Navi GPUs, Intel Cannon Lake platforms. support for raspberry pi (Pi 2B, Pi 3B, Pi 3A+, Pi 3B+, CM3, CM3+, Pi 4B), Significant power-saving improvements. Boot speed improvements through changing the default kernel compression algorithm to lz4 (in Ubuntu 19.10) on most architectures, and changing the default initramfs compression algorithm to lz4 on all architectures.

Toolchain Upgrades 🛠

Ubuntu 20.04 LTS comes with refreshed state-of-the-art toolchain including new upstream releases of glibc 2.31, ☕ OpenJDK 11, rustc 1.41, GCC 9.3, 🐍 Python 3.8.2, 💎 ruby 2.7.0, php 7.4, 🐪 perl 5.30, golang 1.13.

GNOME and visual improvements

Ubuntu 20.04 Focal Fossa comes with installed. It’s chock-full of visual improvements, resulting in better performance and a more aesthetically pleasing graphical experience. There’s also a new lock screen design and support for fractional scaling under X11.

GNOME 3.36

GNOME 3.36

A sleeker theme

GNOME’s new default theme is called “Yaru.” Even upon first loading into Focal Fossa, the desktop gives off a much more modern and sleeker vibe. This is mostly thanks to some color tweaks in the default theme and a darker wallpaper. The updated GNOME also allows you to choose between three different color themes: light, standard, or dark.

Network configuration

With this Ubuntu release, netplan.io has grown multiple new features as well, some of are as below:

  • Basic support for configuring SR-IOV network devices. Starting with netplan.io 0.99, users can declare Virtual Functions for every SR-IOV Physical Function, configure those as any other networking device and set hardware VLAN VF filtering on them.
  • Support for GSM modems via the NetworkManager backend via the modems section.
  • Adding WiFi flags for bssid/band/channel settings.
  • Adding ability to set ipv6-address-generation for the NetworkManager backend and emit-lldp for networkd.

ZFS support

Ubuntu introduced native support of ZFS in the 2019 interim release of Eoan Ermine. In Ubuntu 20.04 Focal Fossa, ZFS support has been further improved, though still flagged as being experimental. When installing Focal Fossa, you have the option to use ZFS if you click “advanced features” when asked about how you’d like to format your hard drive.

The newest version of Ubuntu features performance enhancements for ZFS and support for encryption. Ubuntu has a ZFS system tool called Zsys, which provides automated system and user state saving. It also integrates better with GRUB so a user can revert to an earlier system state before booting into the desktop.

Acceptance of ZFS in the enterprise world is still shaky, but it doesn’t seem to be going anywhere. Seeing support for it on a really popular distribution like Ubuntu is pretty neat.

 

Python3 by default

In 20.04 LTS, the python included in the base system is Python 3.8. Python 2.7 has been moved to universe and is not included by default in any new installs.

Remaining packages in Ubuntu which require Python 2.7 have been updated to use /usr/bin/python2 as their interpreter, and /usr/bin/python is not present by default on any new installs. On systems upgraded from previous releases, /usr/bin/python will continue to point to python2 for compatibility.

Snap Store

The Snap Store (snap-store) replaces ubuntu-software as the default tool for finding and installing packages and snaps.

QEMU

QEMU was updated to 4.2 release. There is so much that it is hard to select individual improvements to highlight, here just a few:

  • free page hinting through virtio-balloon to avoid migrating unused pages which can speed up migrations
  • PPC: NVIDIA V100 GPU/NVLink2 passthrough for spapr using VFIO PCI
  • Many speed improvements for LUKS backend
  • pmem/nvdimm support

For trimmed down container like isolation use-cases the new qemu has the microvm machine type which can be combined with the qboot ROM (available as bios-microvm.bin) to provide a reduced feature set at a much faster startup time. To further emphasize that you can use the package qemu-system-x86-microvm which provides an alternative QEMU binary stripped of all features not needed these use cases as sugegsted by the qboot ROM.

libvirt

libvirt was updated to version 6.0. See the upstream change log for details since version 5.6 that was in Ubuntu 19.04 or further back since verison 4.0 that was in Ubuntu 18.04.

Chrony

Chrony been updated to version 3.5 which provides plenty of improvements in accuracy and controls. Furthermore, it also adds additional isolation for non-x86 by enabling syscall filters on those architectures as well.

To further allow feeding Hardware time into Chrony the package GPSD is now also fully supported.

But still for simple time-sync needs the base system already comes with systemd-timesyncd. Chrony is only needed to act as a time server or if you want the advertised more accurate and efficient syncing.

Ubuntu 20.04 LTS “Focal Fossa”

Ubuntu 20.04 LTS “Focal Fossa”

There are a lot of other changes as well. To experience all the changes and improvements it is recommended to use and experiences this version of your own.

As of late April, Ubuntu 20.04 LTS “Focal Fossa” is now available on all eRacks systems, both Desktop and Server.

It should appear in the “Operating system” dropdown when you configure your system, and is the default on many / most of our systems.

If you don’t see it, or if you this it should be the default, (or shouldn’t!), please let us know – We are always listening for feedback!

eRacks/NAS50 Half Petabytes of Data Storage Server / Cloud Storage

eRacks/NAS50 Half Petabytes of Data Storage Server / Cloud Storage

We were extremely excited to announce the forthcoming release of 500 Terabyte (half Petabyte) storage space upgrade on our flagship product eRacks/NAS50 cloud data storage servers last week.  The new model, to be released shortly, will incorporate 50 HGST 10 Terabyte HelioSeal™ hard drives.  While the new model is not released yet, we are accepting pre-orders from customers.  The current capacity, now available, of the eRacks/NAS50 is 400Terabytes in total, with currently-available 8Terabyte drives.

The new unit is rackmount and holds 50 removable drive bays.  The 9U unit is suitable for any cloud storage application as well as NAS/Local LAN.  eRacks/NAS50™ is also a great solution for media libraries and other applications which require massive amounts of data storage capacity, you just have to make you are also backed up by the best data management services. Visit https://blog.couchbase.com/fuzzy-matching/ and get more information!

Our new servers are truly a remarkable Petascale solution.  The HGST 10 Terabyte HelioSeal™ drives that come with eRacks/NAS50 use two technologies that greatly add to the value that this server carries with it, including other server services from sites as https://www.servermania.com/kb/articles/what-are-the-requirements-for-ubuntu-server/ for ubuntu projects.

The first is referred to as the HelioSeal™ technology.   The HGST hard drives using this technology replace the air inside of the drive with helium.  This would make the drive much lighter as well as allowing the disks to be much thinner.   Due to the helium inside, the thinness of disks will not cause any disruptive turbulence effects.  This will allow us to have more disks inside each drive which in turn means more data space.  Additionally, helium drives have much lower power consumption, as much as 27%, making our NAS50 models truly a green product.

The new drives in the eRacks/NAS50 servers also make use of a technology called SMR.  That is short for Shingled Magnetic Recording.  This technology by itself adds another 25 to 100 percent storage capacity to HGST hard drives.

We are proud of our new eRacks/NAS50 and are ready to take pre-orders.  We are prepared to customize the unit per your instructions with all Open-Source software necessary so your order will reach you completely pre-installed.

Please contact us for pre-orders or any questions you may have.

eRacks Systems NAS36 8TB Seagate Archive Drive upgrade

eRacks Systems NAS36 8TB Seagate Archive Drive upgrade

We can’t help it with our innovations. Our NAS36 servers offered almost 200 Terabytes of data space already. That is considered quite high for a mid-range data storage server. But we just decided to jump even higher and exchange the standard 6-terabyte disks into 8-terabyte ones. That mean our NAS36 model storage servers are now able to hold 288 terabytes of data in total.

The new NAS36 model with higher data capacity brings even more value to our customers not just because of the storage space it provides but also for its price. Yes, we have decided to slash the prices down below $25,000. That is going to bring considerable saving to our customers. [UPDATE Sep 2015:  current price for maxed-out 288TB config with Seagate Archive 8TB drives is just under $22,000]

We are proud to announce this latest upgrade as we continue to provide petascale data storage servers at affordable prices.

We remain dedicated to open-source systems. We also remain committed to delivering pre-installed, pre-configured systems to our customers.

The NAS36 servers are rack-mount servers. We designed the 4U unit specially to hold large number of drives in a very limited space. That leaves ample amount of space for other necessary accessories inside your data center rack.

The 36 drives in the unit are all Seagate Archive Drives, mounted on a single backplane and controlled by a RAID controller. The unit holds 24 drives in front and 12 in the back making the unit case quite compact.

eRacks Systems is a leading provider of high-capacity, petascale data storage server solutions to companies and enterprises requiring massive amounts of storage data.
Our servers are suitable for Cloud Storage application as well as Near-Line Storage. They are also configurable for NAS (Network Attached Storage) applications.

For a great storage solution at a considerable low price, contact us. We are available through email, phone and our website.
