CWWK i5-1235U 6 port i226 report

[Arnavisca]

turn off the internal sd-card reader.
it introduces 1-2% of io delay for no reason.

you can find it with lsblck
if you dont have any sata-drives in the system its most likely /dev/sda.
if there are sata drives in the system it will be something else.

..................

Thanks for the comprehensive answer. I blocked the sd card and I have 1-2% less.

I have only two vms - pfsense and hassio.

I still had high I/O. I only put one nvme drive in there. I/O is below 1%.


Can he ask about your configuration?

Topton, Cwwk?
What discs do you have?

 

[beisser]

i have a topton unit with pentium 8505, so the smallest version.

it has 64GB noname china ram.

i have 1 1TB nvme drive (fanxiang s500pro noname consumer ssd) installed, which is formatted as xfs and is exclusively for my media data for my plex container.
i also have 2 enterprise sata ssd installed (2x intel s3610 1.6TB) which my proxmox boots from and which houses my zfs pools for the VM's.
there are also 2 USB-SSD's. 1 2TB crucial and 1 1TB noname china SSD.



the usb SSD's are passed through to my Server 2022 and are used as Backup Datastores for Veeam.



it also contains an intel b200 wifi7 card, which is passed through to a windows 11 vm for testing purposes.



here a current outside view of my janky homelab:



on top, the server with wifi, bluetooth usb drives and everything.
below a 10G/multigig switch.
left a low power proxmox backup server (old igel thin client, slow as hell, but only draws 7 watt under load).

and then my 2 nas (both running truenas), which store nothing but animated iso files of course



they are just for long term storage and are only powered on, when i need to copy media to the miniserver for consumption.

 

[Arnavisca]

Very nice. Thanks for sharing.

I have a question.
How did you connect the 2x intel ssd disks to the topton?

 

[beisser]

the unit has 2 sata ports on the mainboard and comes with 2 sata cables that fit those ports.

the ssds themselves dont both fit internally, so i placed them unter the computer.

here is a picture:

 

[Arnavisca]

sorry for bad english, google translate helps me...

do you mean this cable?





the other thing is that you use zfs on cheap consumer ssds.
this will cause 2 things.
..................

Does this apply to zfs, zfs raid 1? Or does it apply to other filesystems as well?



I have one disk with btrfs. Is it a good choice?


One more question. Is it a good idea to plug one nvme drive and the other sata drive into raid1? They have a different interface and speed.

 

[beisser]

yes i mean this cable.
the device should have 2 such cables included.
the issue is primarily visible with zfs, due to the nature of how it works.
on other filesystems such als lvm (with ext4) or btrfs or xfs this should be much less of a concern.

but be advised that in terms of data integrity no other filesystem can match zfs on a single node.

technically you can do a raid between nvme and sata.
its waste on the nvme disk though as it will likely wait for the sata disk most of the time.

OK.

Is that command correct? I have this message:

root@delta:~# @reboot root /usr/bin/echo 1 > /sys/block/sda/device/delete 2>&1
-bash: /sys/block/sda/device/delete: No such file or directory

@reboot root /usr/bin/echo 1 > /sys/block/sda/device/delete 2>&1

 

[beisser]

can you show me the output of lsblk?
the first command throws an error that sda doesnt exist.
or did you execute it twice to get the output for this forum?

otherwise the commands look ok.

if everything works correctly you should see the base io delay drop immediately my at least 1 %

 

[Arnavisca]

It works for me.



I made a mistake.

I entered this command

echo 1 > /sys/block/sda/device/delete

and then without reboot this command

@reboot root /usr/bin/echo 1 > /sys/block/sda/device/delete 2>&1

 

[beisser]

the second one is not a command.
its a line you add to crontab.

use crontab -e and add the line (i assume you know how vi works?).
if you dont, you use the cursor keys to go where you want to add the line (it should be empty besides commented out lines), press "i" to insert, paste in the line, press "esc" to leave insert mode and then press ":wq!" without the quotes to save the crontab.

it will then automatically execute it on every reboot.

this is how my crontab looks:

# Edit this file to introduce tasks to be run by cron.
#
# Each task to run has to be defined through a single line
# indicating with different fields when the task will be run
# and what command to run for the task
#
# To define the time you can provide concrete values for
# minute (m), hour (h), day of month (dom), month (mon),
# and day of week (dow) or use '*' in these fields (for 'any').
#
# Notice that tasks will be started based on the cron's system
# daemon's notion of time and timezones.
#
# Output of the crontab jobs (including errors) is sent through
# email to the user the crontab file belongs to (unless redirected).
#
# For example, you can run a backup of all your user accounts
# at 5 a.m every week with:
# 0 5 * * 1 tar -zcf /var/backups/home.tgz /home/
#
# For more information see the manual pages of crontab(5) and cron(8)
#
# m h  dom mon dow   command
@reboot root /usr/bin/echo 1 > /sys/block/sdd/device/delete 2>&1

I did it using nano. It works, thanks

 

[DougQuaid]

there seems to be newer bios from december, anyone tried it?

[beisser]

i didnt. the pc runs fine with fta's modded bios. i see no need to upgrade if i dont have any issues.

Does anyone know where to buy such a cable? I only got one.

Thank you very much

BUMP (Jan 8, 2024) ...

Quick question: is the CPU fan header "5v" on the i5 1240P model, and if so, does it support PWM? I have a NF-A8 5V PWM and the BIOS reports only 450 RPM.

After searching the thread, I was unable to find the answer.

 

[beisser]

it is a 5v header and it doesnt seem to be pwm. my 12v pwm fan visibly always seems to run at the same (low) speed. at least there was some setting in the bios where you could specify at which temperatures the fan turns off and on (if i dont misremember now), so you can set a semi passive mode until the unit gets warm enough for the fan.

i set mine to always run though.

unfortunately you can see what speed the fan is running at in linux. neither lm-sensors nor s-tui report it.

To see fan speed and additional temperature and voltage sensors in linux, you can use it87 module

There's now on aliexpress (with EU stock) a brand called Yohirs and it seems to use older case and includes a fan and ventilation cutout for it. It's 120 to 170 euros cheaper than same config with i1235U from Topton. Any reason i should not pick this one ? (Can i use the modded bios from this thread etc ?)

https://a.aliexpress.com/_EuiAQzt

Or should I get the newer 13th gen version instead ? But I hear they are more problematic....ideally i would want completely fanless if possible
