Last time I check, X10 and more recent board doesn't provide access to the BCM using i2c. This make it impossible to control the fan from the operating system.
Hello,
I need you opinion about the poor performance I've observed on a pretty decent server.
The following stat was observed while creating a GIN Index in a postgresql database.
e.g.:
iostat -x -m 3
avg-cpu: %user %nice %system %iowait %steal %idle
0.51 0.00 9.24...
If I plan to go with the 2U server CSE-826. Would you have any recommendation to replace the fan with quiet version of them ?
Otherwise, I understand it's better to go with the 4U server.
Hello,
I'm looking for affordable rack mountable server chassis with SAS backplane with at least 6 disk or more. Quiet. And if possible with dual PSU.
So far, I had a look at Supermicro CSE-826 from "The server Store". at 199$ USD + shipping it's a good option but I'm not sure the fan in the...
Hello,
From Canada / Quebec, I'm looking fo a Supermicro chassis 1U. Ideally a CSE-512L.
There are many on amazon or ebay but those are way to expensive for my need. Looking for something used under 100$.
BTW, the value "3" is not skipped. It's available on some board like mine: X9DRT
It's mean: Set Fan to PUE(Power Utilization Effectiveness) Optimal Speed
With some testing on a bench test, I notice some of the disk had a jumper in the back and others did not have a jumper. Seems this little jumper is causing all the issue. Disks without a jumper is properly detected by the LSI 9210-8i controller. While disks with a jumper are completely ignored...
Hello,
I own a LSI 9210-8i controller. We installed it with 12 HDD. Those are various model of 2TB Western Digital. Some are red, other are green. When starting the server with these drives, only 4 disk get detected (the red one).
We have tested with various cable. We also try other LSI...
Yep, I have the feeling GlusterFs or Ceph doesn't fit our need since we don't plan to have more than 3 nodes. As Patrik mention, there is a huge performance drop using this technology. Figuring out the storage for Kubernetes is not that easy... We usually use Proxmox ZFS storage replication when...
Hello,
As I don't have a lot of experience setting up OpenShift and Kubernetes, I'm asking for help here as a way to brainstorm and find creative way to leverage our existing infrastructure.
As a new initiative to embrace Docker, we start dockerizing all our software and we are deploying them...
Because I cannot find alot of resources related to kubernetes on STH, I want to revive this post and provide my feedback.
I also feel kubernetes is overkill for home lab.Still, If you only have a single node (a master) it's very to start a new kubernetes instance with minikube. It can also be...
Hey !
I manage to have some control over the fan Speed. Nutoton W83795G chipset provide alot of control over the fan speed. It's full of option and the SuperMicro BIOS and IPMI expose very very little. I'm really impress by the granularity available.
I've wrote a little python script to change...
Well, after reading the code. It seams the driver is buggy when used with IPMI. The driver tries to override the chipset registry (erasing value set by BIOS). So I disable both driver: w83627ehf and w83795g. Now I attempt to directly write into the registry based on w83795g implementation and...
After some googling and digging. Linux is loading two driver for the BCM: w83627ehf and w83795g
dmesg has the following output.
In sysfs, I previsouly found `/sys/devices/platform/w83627ehf.2576` but I also found another path `/sys/devices/pci0000:00/0000:00:1f.3/i2c-0/0-002f` provided by...
The value reported by the DIMM seams to be in normal range.
IMO, the Winbound chipset W83627DHG-P is detected by the kernel and I loaded the proper driver w83627ehf. I tried to change the value directly using the sysfs (/sys/devices/platform/w83627ehf.2576) but whatever the value I set, it...
Yep, I've set the fan control speed to "Energy Saving/ES". The fan does down to 6500RPM.
I cannot change the Fan speed in IPMI. I need to change it in BIOS.
