HP Microserver Gen8

[Potuk2020]

Hi
Decided to move to this after reading reviews, but am getting really poor performance from the SMB shares, copy speeds of approx 10Mb/s, thought it may be the Broadcom onboard NIC but replaced with an interactive E1000 Nic and am still getting the same write speeds, any help.

System Spec
4 WD WD40EFRX Red 4TB drives - AHPCI mode
16Gb Memory
HP Proliant Microcsever Gen8

Any ideas would be greatly appreciated.

Can post more information if required, has anyone else had this issue and managed to get resolved?

Try replacing your network cable.

Do you have the other end plugged into a gigabit switch?

I have replaced all cables, and yes is a gigabit switch, if I do internal test I get the following DD write and read speeds respectively but same SMB write speed over a gigabit network connection.

Write Speed
20971520000 bytes transferred in 13.726611 secs (1527800282 bytes/sec)
Read Speed
20971520000 bytes transferred in 6.359359 secs (3297741216 bytes/sec)

So that equates to just over 3GB/s write and 1.5GB/s read speed is that inline with what would be expected with this setup.

Any luck resolving the problem? I also have just about 10mb/s with this machine.
How did you perform the internal DD write test?

I hope you meant 10 MB/s. I'm getting 45 MB/s read and 33 MB/s write with a GEN8 and that's wirelessly. How are you connected to the GEN8? Are you getting the same results using a different client?

It is probably a software issue with SMB, because my NFS shares on GEN8 (with a Celeron G1610T and spinning disks) run at 130 MB/s.

Try running the internal DD tests against the samba share mounted locally. That should determine if it's the network or samba.

What's in the network path between the Gen 8 and your client? Are you getting the same result from a different client? There are recent posts involving dodgy switches and outdated clients that were the cause of poor transfer speeds. The issue may not be with the MicroServer at all.
