Re: Hewlet Packard DL380 Support

CentOS 8 runs without problem on my DL380 G7 and DL360 G7 servers. The only incompatibility I had was with a NIC. I did have to replace the 10GbE NC552SFP NIC with an HP 560SFP+ NIC because the NC552SFP is no longer supported. For Proliant servers older than G7, try adding the following switch to th...

Re: 7.7.1908 Estimated Release Date?

7.7.1908 appears to be replicating to the mirrors now. My guess is as soon as it has reached most or all mirrors it will be officially announced.

Re: Poor performance with HP NC552SFP 10GbE NIC

Yeah, scp is not a good test tool for this. It uses encryption and is limited to a single core for that so the bottleneck in that case becomes "how fast can you encrypt the data". Try installing and using iperf3 (from EPEL) or configuring e.g an httpd server to serve the files you want to transfer ...

Re: Poor performance with HP NC552SFP 10GbE NIC

What is the output from ethtool $interface (where $interface is the name of the right interface) ? What tool are you using to measure the throughput and to generate that traffic? I created a 10GB ramdisk on each server and transferred an 8GB file between the ramdisks using scp. I did this to elimin...

Poor performance with HP NC552SFP 10GbE NIC

I have CentOS 7.5 running on two HP DL360-G7 servers, each with 96GB RAM. The BIOS and all the firmware are up-to-date on the servers. I recently installed one NC552SFP 10GbE fiber NIC in each server. The NIC's firmware is also up-to-date. I then configured IP on the new NIC interface and deactivate...
