Performance Slow writing problem

[lokewing]

Hi all,

I have bought an machine to build up freenas system, i facing writing speed performance problem and can't found where is the bottleneck, Can someone please advise? TQVM

below is my hardware list.

1x Intel® Xeon® E5-2620 v3 (6C, 15M Cache, 2.40 GHz, 8.0 GT/s Intel® QPI, D4 1866, TB, HT, 85W)
- 2x 16GB RDIMM, DDR4 2133MHz, 1.2V
- 2x 3.5" 1TB 7.2K RPM 6Gbps NL-SAS HDD
- 2x 3.5" 6TB 7.2K RPM 12Gbps NL-SAS HDD
- 8x 2.5" 480GB MLC 12Gbps SAS SSD (Samsung Enterprise Series, 12Gbps, 1 DWPD)
- 1x Intel 10Gbps SFP+ Dual Port mezzanine card (OCP)
- 1x LSI SAS 3108 mezzanine card for RAID 0/1/5/10, 12Gbps, 1GB Cache
- 1x LSI CacheVault LSI SAS 3108
- 1x Ethernet Server Adapter Intel 82599 PCIE 2.0 Dual Port 10GbE SFP

Below is all my config for freenas and exsi server

in my Esxi server, i already create 3 VMkernel Port with ISCSI binding to link MPIO with freenas and assign 1 virtual harddisk for testing.

Benchmark test

Thanks,
Loke

1x LSI SAS 3108 mezzanine card for RAID 0/1/5/10, 12Gbps, 1GB Cache

This appears to be a RAID card. These are not ideal for ZFS. I highly recommend replacing it with an HBA.

Or better, since it's a mezzanine card, consider if it's possible to install the IT firmware on it.

Doubt it works on an SAS 3108, but I do think that the SAS3 software stack allows for non-RAID drives in all configurations, not just IT/IR.

Hi Sakura,

thanks your reply, I had change my card to LSI 9300 8I HBA card and come out another problem which is my 1st slot hdd drive is not recognized by freenas and even tried upgrade to new version Freenas 9.10.1-U1(ff51a5d)

In the HBA card BIOS Page My 1st slot hard drive is shown SAMSUNG SAS SSD but freenas is not recognized.

Can someone please advise? TQVM

I'll bet your backplane is SAS2. Right? I've seen this happen with SAS3 HBA attached to SAS2 backplanes but not for ~8-10 months. What firmware version was your LSI9300-8i?

 

[Ericloewe]

Backplane firmware might need an update, too.

Hi Depasseg,

how to check my backplane is SAS 2 or SAS 3? My HBA card version is 12.00.00.00 IT.

Hi Ericloewe,

I'm new in this machine, do you have any guide can give me for how to upgrade backplane firmware?

 

[Ericloewe]

No, but the manufacturer will have one.

What is the make and model of your chassis?
