How fast is a NVMe SSD Cache? - 20GbE speed test on DS1621+ (answer: Very)

The Synology DS1621+ has two lighting fast NVMe slots, but can it handle serving SMB streams at 2GB of data per second? In this video we test out link 2x 10G...

Just jump to the end and he talks about how he's saturated two 10gb connections with this file transfer?

You'll get 10 Gbps on each client (if the NAS can keep up), if you start a transfer on a second client it may use the other leg of the link and you'd get 10 Gbps there. The reality is that it'll be 10 Gbps for the vast majority of cases.

I know it does earlier, but I thought at the end he transfers and times a single file on his laptop? If not, then that makes sense!

He still does two transfers later on, he doesn't show it on the video due to the earlier result being affected by the screen recording.

It is possible to use multiple connections using a single client by using SMB3 Multichannel:

Link Aggregation can absolutely increase bandwidth. Its not just a redundancy implementation.

True but it's very rare circumstances that a single client will support more than one leg (multi-channel SMB as an example which requires server and client support). In the vast majority of home use cases, the second leg won't be used.
 
Agreed, not going to see major benefit in single client to single server situations. Aggregation normally sits within core infrastructure where link saturation is more likely.

I used multi channel on mine and get 20Gb transfers with 2x10gb links so the data between my NAS and Desktop is very quick, rather than having loads of storage on my Desktop I couldn't share well with other I moved my storage centrally and use it like this and have a much more lightweight desktop, sure its not as fast as native NVME but I am often just doing big dumps back and forth rather than a lot of random access.

All SSD in my NAS 6xNVME and 8xSata right now mostly because its in the room with me and spinners got on my nerve.

I've 2 bricks and motar sites each with their own BB but one is rock solid and the other not so rock solid. They are close and currently I have a unifi UBB connecting them as a backup (not currently being used)
What do I need to do to be able to use the UBB but separate that side of the network. So neither site can access Tills, SONOS etc.

You'd either have to put the clients on a guest VLAN, or put them on a normal VLAN and set up F/W rules to block access to services you don't want.
 
Another change that should be simple but it never works that way with my Ubiquiti kit! As my CK2+ is the only device in my rack with a hard disk I wanted to swap it out with an SSD to avoid knocks when working on the rack (its only used for the network controller so no concern about wear as it stores config/backups only)

Sadly after performing the swap and despite the Unifi OS dashboard showing the new drive correctly and other pages working, its main dashboard page just shows an empty middle section with a message "“You have limited permissions" and I cannot launch the network controller :(

A restore of the config didn't help and in the end I swapped back the original drive and its working again. Next attempt will be a factory reset and hopefully it will reload the previous config (or possibly clone the HDD to the new drive first and hope that doesn't cause an issue). If that fails then its probably time to virtualise the controller install but I thought this swap would be a ten minute task!

I am so glad I moved firewalling to a more capable and reliable platform so at least my Unifi woes cannot take that down.
 
Anyone else with the AC Pro? I've been noticing the 5GHz channel sometimes changes to a random channel in the high range where most devices aren't even compatible (149+), usually after a couple of weeks. I have it fixed to 52 usually and it's not been a problem until recently. I think it could be due to the latest firmware but wanted to check with others before I roll back. My 6 Pro on the other hand has been rock solid.

Did you back up and restore during the change? The config is stored on the HDD.

I did restore the config using the Unifi OS console after the issue appeared to no effect.

Before that on first boot with the new drive the Unifi OS came up as normal without prompting for a backup which isn't what I expected. It still had the old users listed so they were retained, presumably from internal storage as although the device also has an SD card that only ever seems to be used for application backups.

Have you tried saving the backup, factory reset, replace drive, then restore config?

Not yet, that's my next approach as mentioned. However I am going to wait until I've had time to create a long term VM/Docker with a backup controller and resist the urge to use that full time.

Turn off the auto-channel ‘optimisation’ and it will stay put.
