I have a Hypervisor server with Linux VMs. The VM is capped at 1G speeds as it's using a "VM" interface on the hypervisor and the NAS itself has multiple SMB shares all on a 10G fiber.
The NAS specs:
2630v3L
96GB ram
HBA H310 Mini IT Mode
8x 7200 RPM 6TB disks
ZFS Raid2
10G fiber to 10G port on switch for SMB Shares
I am mounting the cifs share via fstab and I'm using this command to write a test file.
With that I get about 37mbps writes.
Is this not supposed to be faster? Closer to 100mbps? There's not really a whole lot of data being written from other VM's to the datastore so I don't think there's anything causing performance issues. The dataset that's being written to has sync and everything else disabled. It does have LZ4 compression
For the Network:
pfsense
VLAN for VM's and another VLAN for the nas
Theres one switch for the whole setup.
The switch is layer 2
What I want to know is there something that could be potentially causing the slow writes? I understand with the setup for the NAS that it's not the fastest in the world, but shouldn't it be "faster"? Let me know if there's anything else I can post here for clues or questions about anything else on my setup.
