A Dummy Display Dongle for My Headless Workstation

Since back in December, I have a ‘Headless’ HP Z440 workstation under my desk with lots of RAM, storage and an Nvidia graphics card to run virtual machines and compute intensive stuff there instead of on my notebook. This works very well in practice and I use X over SSH a lot with virtual machines … Continue reading A Dummy Display Dongle for My Headless Workstation

SSD, ZFS and VM performance – Workstation Power At Home – Part 12

Now that I have my ZFS filesystem spanning several drives in place on my Z440, I wanted to get an idea of how this setup is performing together with the underlying LUKS encryption. And while I am at it, the other questions I had in mind were: How does this compare to the ext4/LUKS combination … Continue reading SSD, ZFS and VM performance – Workstation Power At Home – Part 12

ZFS for Storage – A Primer – Workstation Power At Home – Part 10

In previous parts of this series I’ve been looking at CPU power, GPU power, virtualization, remote graphical GUIs and networking of my refurbished Z440 workstation. The next thing on my list of things I wanted to improve in my computing setup was storage. So far, I was mostly using ext4 filesystems on partitions on physical … Continue reading ZFS for Storage – A Primer – Workstation Power At Home – Part 10

Remote Visual Computing with RDP – Workstation Power At Home – Part 5

In addition to running computing intensive applications on my new (refurbished) HP Z440 workstation the other main use case for me is to offload the virtual machines I am running on my notebook today. While I do have 16 GB of RAM in my notebook it becomes more and more difficult to run two virtual … Continue reading Remote Visual Computing with RDP – Workstation Power At Home – Part 5

Some Thoughts On Single Core Performance – Notebook vs. Datacenter

I guess you have noticed the one or other of my recent articles over the past few weeks about the experience I have gained with my new ‘refurbished’ workstation. While I previously thought that single core performance of  x86 processors in high end workstations and particularly in data centers must be so much more powerful … Continue reading Some Thoughts On Single Core Performance – Notebook vs. Datacenter

Workstation Power at Home – Part 4 – Power and Remote Suspend

High processing power comes with high power consumption. I guess that can’t be helped much but one way to reduce the power bill for that number-crunching ‘headless’ workstation under the desk without screen and keyboard is to suspend it at night and at times during the day when it is not needed. As long as … Continue reading Workstation Power at Home – Part 4 – Power and Remote Suspend

Workstation Power at Home – Part 2 – FFmpeg

This is part 2 in my article series on using a Xeon based 6 core 12 thread workstation at home to offload CPU intensive tasks from my notebook to a more powerful and fast server. At the end of the introduction I had an example of how my picture fix, rotate compression tool runs 5 … Continue reading Workstation Power at Home – Part 2 – FFmpeg
