Ting_sf Posted February 14, 2022 #1 Posted February 14, 2022 Hey; I used a xpenology backup template to install a x3615xs, no issue. DSM = 6.2.3.25426 Loader - Jun 1.04b I think My question is why my sata link speed only showing 1.5 gbps? I was expecting 6 gbps like in a baremetal setup I did before. I am not even sure this is a Proxmox setting issue or is Xpenology thing? anybody has similar question and found a solution before? Please see below dmesg result, and I also attached a screen shot of my proxmox vm thanks in advance. I used "dmesg | grep-i SATA", here is the results: [ 1.667473] ahci 0000:00:1f.2: AHCI 0001.0000 32 slots 6 ports 1.5 Gbps 0x3f impl SATA mode [ 1.687124] ata1: SATA max UDMA/133 abar m4096@0xfea1b000 port 0xfea1b100 irq 44 [ 1.687132] ata2: SATA max UDMA/133 abar m4096@0xfea1b000 port 0xfea1b180 irq 44 [ 1.687138] ata3: SATA max UDMA/133 abar m4096@0xfea1b000 port 0xfea1b200 irq 44 [ 1.687144] ata4: SATA max UDMA/133 abar m4096@0xfea1b000 port 0xfea1b280 irq 44 [ 1.687151] ata5: SATA max UDMA/133 abar m4096@0xfea1b000 port 0xfea1b300 irq 44 [ 1.687157] ata6: SATA max UDMA/133 abar m4096@0xfea1b000 port 0xfea1b380 irq 44 [ 1.688203] ahci 0000:06:07.0: AHCI 0001.0000 32 slots 6 ports 1.5 Gbps 0x3f impl SATA mode [ 1.706898] ata7: SATA max UDMA/133 abar m4096@0xfde80000 port 0xfde80100 irq 45 [ 1.706906] ata8: SATA max UDMA/133 abar m4096@0xfde80000 port 0xfde80180 irq 45 [ 1.706912] ata9: SATA max UDMA/133 abar m4096@0xfde80000 port 0xfde80200 irq 45 [ 1.706919] ata10: SATA max UDMA/133 abar m4096@0xfde80000 port 0xfde80280 irq 45 [ 1.706925] ata11: SATA max UDMA/133 abar m4096@0xfde80000 port 0xfde80300 irq 45 [ 1.706931] ata12: SATA max UDMA/133 abar m4096@0xfde80000 port 0xfde80380 irq 45 [ 1.993211] ata1: SATA link down (SStatus 0 SControl 300) [ 1.994214] ata3: SATA link down (SStatus 0 SControl 300) [ 1.994379] ata4: SATA link down (SStatus 0 SControl 300) [ 1.994533] ata2: SATA link down (SStatus 0 SControl 300) [ 1.994670] ata6: SATA link down (SStatus 0 SControl 300) [ 1.994822] ata5: SATA link down (SStatus 0 SControl 300) [ 2.012237] ata7: SATA link up 1.5 Gbps (SStatus 113 SControl 300) [ 2.012424] ata8: SATA link up 1.5 Gbps (SStatus 113 SControl 300) [ 2.013157] ata12: SATA link up 1.5 Gbps (SStatus 113 SControl 300) [ 2.013322] ata10: SATA link up 1.5 Gbps (SStatus 113 SControl 300) [ 2.014174] ata9: SATA link up 1.5 Gbps (SStatus 113 SControl 300) [ 2.014334] ata11: SATA link up 1.5 Gbps (SStatus 113 SControl 300) [ 2.358960] aic94xx: Adaptec aic94xx SAS/SATA driver version 1.0.3 loaded [ 2.369232] LSI 3ware SAS/SATA-RAID Controller device driver for Linux v3.26.02.000.

flyride Posted February 14, 2022 #2 Posted February 14, 2022 Cannot speak to Proxmox, but if I inspect my DSM 6.2.3 running on ESXi, I get no SATA connection speed status on virtual disks, but valid 6.0 Gbps for physical. Virtual disk is being presented as a SATA device for compatibility purposes, yet the device in question operates at full speed (>1GBps in the case of this NVMe backed store). Why don't you test your virtual disk and see if you get >150MBps and if you do, clearly are not limited by whatever you find in dmesg. root@nas:~# smartctl -d sat -i /dev/sda smartctl 6.5 (build date Mar 12 2020) [x86_64-linux-3.10.105] (local build) Copyright (C) 2002-16, Bruce Allen, Christian Franke, www.smartmontools.org === START OF INFORMATION SECTION === Device Model: VMware Virtual SATA Hard Drive Serial Number: 10000000000000000001 LU WWN Device Id: 5 000c29 bafa731d8 Firmware Version: 00000001 User Capacity: 2,000,398,934,016 bytes [2.00 TB] Sector Size: 512 bytes logical/physical Rotation Rate: Solid State Device Device is: Not in smartctl database [for details use: -P showall] ATA Version is: ATA/ATAPI-6 T13/1410D revision 0 Local Time is: Mon Feb 14 12:28:40 2022 PST SMART support is: Unavailable - device lacks SMART capability. root@nas:~# smartctl -d sat -i /dev/sdh smartctl 6.5 (build date Mar 12 2020) [x86_64-linux-3.10.105] (local build) Copyright (C) 2002-16, Bruce Allen, Christian Franke, www.smartmontools.org === START OF INFORMATION SECTION === Model Family: Samsung based SSDs Device Model: SAMSUNG MZ7LM3T8HCJM-00003 Serial Number: [redacted] LU WWN Device Id: 5 002538 c0009dd5d Firmware Version: GXT3003Q User Capacity: 3,840,755,982,336 bytes [3.84 TB] Sector Size: 512 bytes logical/physical Rotation Rate: Solid State Device Device is: In smartctl database [for details use: -P show] ATA Version is: ACS-2, ATA8-ACS T13/1699-D revision 4c SATA Version is: SATA 3.1, 6.0 Gb/s (current: 6.0 Gb/s) Local Time is: Mon Feb 14 12:30:43 2022 PST SMART support is: Available - device has SMART capability.

Ting_sf Posted February 14, 2022 Author #3 Posted February 14, 2022 thanks for your reply. I tested before, it started with 700MB/s, but quickly dropped and stay at 200MB/s, I thought it should be around 500MB/s because it should 6bps speed. Am I correct? or I expected too much? Quote
flyride Posted February 14, 2022 #4 Posted February 14, 2022 Someone with Proxmox experience needs to answer that. But if it is actually being bottlenecked by SATA 1.5 you should see a max of about 120MBps. Again this is all virtualized right? So the SATA specs may not mean anything as it is emulated in the first place. What's the actual performance of your underlying storage? Quote
Ting_sf Posted February 14, 2022 Author #5 Posted February 14, 2022 1. yes, it is fully virtualized 2. this 3615xs is on a 10g network, and on the same network, between two fully virtualized window server, 750MB/s read, and 400MB/s write. Thanks. Quote
