Message 3107 - Posted: 19 Sep 2019, 10:24:49 UTC

In next 3-4 days will be some short breaks in server working.
I need make some works in my workshop:
1. connect back up server (named "atena")to my network,
2. configure everything
3. make tests for different configurations
4. add more RAM to proxmox server
5. add more RAM for main storage "bysior".

At this moment I am making backup of every think <- backup is always good idea

After some hard testing I am sure that my proxmox server is really bad performance and I need to buy new one.
My both storage give me full 10gb transfers (1.2 gigabytes per seconds) , but proxmox can download/upload only 300-350MB/sec <- megabytes per seconds.
I will do more test, but I am looking for onother server.

Result of test.
Every test was made on easy system <- every VM was stoped

Legend:
prox01 <- my proxmox server
bysior <- ZFS VM disk storage ( ZFS 11x2 (2x4TB) + 2xHDD spare + 4x Intel SSD as L2ARC )
atena <- ZFS backup storage

What test I have done <- I transfer big iso file 5GB and I am using iperf 3. I test about 10 times and get average
1. From atena to prox01 <- only 200-250Mb/s
2. From bysior to prox01 <- only 200-220Mb/s

3. From prox01 to atena <- full speed 1Gb/s
4. From bysior to atena <- full 1Gb/s

5. from atena to bysior <- full speed 1Gb/s
6. From prox01 to bysior <- full speed 1Gb/s

So summary I have very slow download on prox01 with 10gb.
I will try to check two possibilities:
1. My FreeNas (bysior, atena) need to be tunning to upload more <- but between bysior and atena I have full speed
2. prox01 have CPU X5570 without AES suppor and that cause performance down on 10gb download

ps.: What is interesting I have my PC in the same 10gb network with prox01, atena, bysior and I can only download/upload 40Mb/s on 10gb link <- I will have to check it latter
ps2.: My configuration 10gb is that:
1. prox01 have Intel 4x10gb card
2. bysior has 2x10gb integrated
3. atena has 2x10gb integrated
4. PC have Intel X520 card

bysior, atena and my PC is connected to prox01.
On prox01 I have vmbr1 which is linux bridge which included all 4 ports of intel 4x10gb card

If I want to copy file from PC to any server (prox01, bysior, atena) I have only 40 megabytes per sec transfer <- upload and download.
