Hi All,
I currently have a problem with my 2009 CentOS 7.9 that when I have a client that writes to the server via direct connection via 1Gbit I don't have any problems but when switching to 10Gbit I have the phantom that the connection breaks when I want to write 600MB/s to the RAID. So it writes the data for a random time and then the connections has 0MB/s and then the connection gets restarted. The total RAID speed is about 1,6GB/s.
The network config (direct connection):
TYPE="Ethernet"
PROXY_METHOD="none"
BROWSER_ONLY="no"
BOOTPROTO="none"
IPADDR="172.16.5.10"
PREFIX="24"
DEFROUTE="yes"
IPV4_FAILURE_FATAL="no"
IPV6INIT="no"
NAME="p3p1"
UUID="f6c0713a-d89d-4162-8dc2-e0f4c99a7fa0"
DEVICE="p3p1"
ONBOOT="yes"
I also added
/sbin/ifconfig p3p1 txqueuelen 10000 &>/dev/null
ethtool -A p3p1 tx on rx on
ethtool -A p3p1 autoneg on
Kind regards,
10Gbit Connections breaks
Re: 10Gbit Connections breaks
I do wish they hadn't decided to name the version after YYMM as 2009 sounds like it's 12 years old
Please show us the output from lspci -nn | grep -i net so we can see the exact model of network card that you have in the machine.
Also, check in /var/log/messages for things that may relate to the problem and show us those (and a few lines on either side for context)

The future appears to be RHEL or Debian. I think I'm going Debian.

@BShT: I changed already the cables to the new ones and still have the problem.

Re: 10Gbit Connections breaks
So, yes, 10GBASE-T will be extremely sensitive to cable quality so make sure you are using good quality CAT7 ones.06:00.0 Ethernet controller [0200]: Intel Corporation Ethernet Controller X710/X557-AT 10GBASE-T [8086:1589] (rev 02)
X710 cards were known for having problems when they were first released but most of those problems have now been fixed via firmware upgrades. I would suggest checking to see what firmware your card has and upgrading it if it is not the latest. How you do that for a Supermicro card, I do not know. For Dell cards they supply linux executables that perform the upgrade.
