Any tips for upgrading the drive in a CK gen2+?

As far as I can tell I just need to take backups then swap the drives and restore, how hard can it be What could possibly go wrong?

Sounds like someone was listening

2.5GbE on the WAN port seems a bit of a cop out. What are the speed of the SFP LAN ports - if it has any?

Same as the original unit, it has 2 SFP+ (10GbE) ports for LAN / WAN2 (Assignable)

The SE unit also has 8 x 1GbE PoE ports, where are the OE UDMP doesn't.

What's the difference between the SE version and standard?

• 2.5Gbe WAN
• POE on the switch ports
• integrated 128GB SSD

Anything else?

Edit: I would say that this puts the rumours to bed that they will be dropping the UDM Pro otherwise why would they release a new version?

I wonder if they have updated the backplane on the 8 x 1Gb ports, I guess we will find out soon enough.

Is it currently a fully switched backplane or shared?

Here is the data sheet for it - https://dl.ubnt.com/ds/udm-pro-se_ds

The normal UDM-P is shared with the EA models had a 2.5Gb backplane.

 

[ChrisD.]

No switching throughput on that data sheet, which is a shame. I'd wager you can't drive 1 GbE through all 8 ports at once.

From what I'm reading they are sharing/limited to 1GB? Reddit post though.

It's not too much of a issue if use the 10Gb LAN as a uplink to a switch but it would have been a nice to have for a all in one unit.

It's most likey a shared backplane (1Gb) and I would assume so till told otherwise.

 

[BlizzardX]

Is it a proper switch inside the UDM pro and can devices connected to the 1GBe ports send data at 1gbe speeds across all ports at the same time, i.e. 8gbps non-blocking throughput (16gbps switching capacity)? I thought I read it had issues but I've never bothered to ask.

It doesn't look like it ^ Looks like a shared backplane.

That's meant to be the block diagram for the UDM-P (https://ubntwiki.com/products/unifi/unifi_dream_machine_pro)

So this suggests it has got 8gbps switching capacity? What about vlan/subnet routing presume this is shared 1gbps due to the link to the CPU?

or 2.5Gbps on the 3.1 revision by the looks of it.

Ok so the advantage of the SE is not only the stuff I posted but vlan / subnet switching at 2.5gbps rather than 1gpbs potentially.

If it is 2.5 Gbps then that's crap if I'm being brutally honest. Enterprise has been well beyond 10 Gbps for some time now. It's a 'Pro' device and really should have 10 Gbps ports all round regardless of copper or SFP+.
