Limits on Everything – The Isoblog.
Posted by jpluimers on 2018/05/01
Via [WayBack] Limits on Everything – The Isoblog.:
A posting at Brave New Geek about limits on everything, for example limits on message sizes and numbers of in-flight messages in message queues. Interesting read.
Very interesting read indeed: [WayBack] Take It to the Limit: Considerations for Building Reliable Systems – Brave New Geek
You have to set limits, which begs for a few questions:
- how to find out which limits and at what levels
- how to enforce these limits
Food for thought…
The first can be done with benchmarking, see for instance these from the same blogs above:
- [WayBack] Benchmark Responsibly – Brave New Geek
- [WayBack] Benchmarking Message Queue Latency – Brave New Geek
- [WayBack] Load, Load Testing and Benchmarking – The Isoblog.
Enforcing limits depends in your infrastructure and your communication stacks.

Intel SSD 600p Series NVMe SSD Temperatures: ensure you cool it properly even for moderate use
Posted by jpluimers on 2018/04/30
A short while ago, I installed a pair of 1TB Intel 600p NVMe SSD devices.
Performing a straight rsync backup of some 100 gigabyte of data managed to shutdown both of them: the throttling was so much that VMware ESXi lost the volumes on it and showed “Permanently inaccessible device”.
I was quite surprised as the initial reviews did not mention any temperature problems, but apparently there are.
Since then I’ve put a 120mm fan near to it which made the problems go away, but it still every now and then jumped to over 60 degrees Celsius.
Later I “fixed” it in a better way for cooling getting the idle temperature around 30 degrees Celsius and heavy duty temperatures around 40 degrees Celsius:
- Put the NVME drives each on a fan supported PCIe 4x adapter which has different names in the USA and Europe:
- USA: search for
B01NAQPE6J; [WayBack] Amazon.com: Sintech M.2(NGFF) M-Key PCIe 3.0 X4 Card For Samsung SM951 PM951 950 960 PRO SSD: Computers & Accessories- Europe: search for
B06WGLK4CC; [Archive.is] KALEA-INFORMATIQUE © Controller Card PCIe x4 PCIe: AmazonSmile: Electronics- A [WayBack] NF S12A FLX: Noctua 120mm case fan over all the PCIe slots to cool even further
- Added more fans to the [WayBack] Fractal Design: R5 case to ensure better inlet/outlet air flow, especially over the PCI slots and drives using fans of these types:
- Stock 140mm [WayBack] Fractal Design: Dynamic GP-14
- Extra [WayBack] NF-A14 FLX: Noctua 140mm case fan
- Extra [WayBack] NF A6x25 FLX: Noctua 60mm case fan
- Later I will likely replace the fans on the PCIe adapters with a pair of [WayBack] NF A4x10 FLX: Noctua 40mm fans, 10mm height
I did not have to mount any M.2 heatsinks on them yet; they probably won’t fit under the fan anyway

M.2 SSD heat …
Before we will come to the benchmark results, we want to show something very special on OCinside.de and that is the heat distribution and temperature of the M.2 SSD with an infrared thermal imaging camera, which also supports image overlay and results in an interesting mixture of the infrared image and real image.
According to the internal temperature diode, there was a temperature of approx. 41°C in idle and up to 70°C under load. With an external temperature sensor and the thermal imaging camera, we’ve measures approx. 18 degrees Celsius more than the internal temperature diode outputs and achieve a maximum M.2 SSD temperature of approx. 87.8°C.
Tip:
Who like to reduce the SSD temperature, for example could:
a) adjust the power saving mode.
b) perform an active SSD cooling by direct ventilation.
c) apply commercially available silicone heat transfer pads to the top and bottom of the PCB.
d) purchase a special heatsink for M.2 SSDs.
e) buy a M.2 PCIe card with heatsink.

Backup & Sync: The ridiculous steps you need to move the Google Drive from the C: drive to the D: drive
Posted by jpluimers on 2018/04/27
Unlike for instance DropBox, Google Backup & Sync does not allow you do move the Google Drive location in a one-step way. You have to go through below ridiculous steps to move it around yourself.
A comment on G+ indicated I should try Insync. Not free, but way more stable and more features.

On my research list: Home – Outpan as it is a key-value store of EAN (actually GTIN, so including GS1 UPC, EAN which means barcodes like UPC-12, EAN-8, EAN-13 and ITF-14).
- [WayBack] Global Trade Item Number – Wikipedia
- [WayBack] API Documentation – Outpan Developers
Legacy API
