Oh sure I get the trunk situation, but that doesn't solve my problem today that we're saturating those 2G links with the amount of data we're passing over them Going by my OP, the Ubiquiti and the 2530 was in the same cabinet (which needs to be quiet), whereas the 2920s would be in other locations/buildings. There isn't a 10G server section at the moment, it's about the number of devices we're using as a whole. The problem is there isn't really a go between with our current 2G trunks and 10G, it'll give us plenty of room to expand in future, and whilst money isn't going to be too much of an issue at the moment, I'd rather ask for more than we need than regret it in two years' time. I can effectively ignore the old switches for this, most of them are 24 port and taking up cab space the 48 ports above will need, hence us running out of switchports. I'm kind of glad you posted this, I see a lot of people with vendettas against Ubiquiti because they aren't charging Cisco prices, but their EdgeSwitch line runs a fork of VyOS so I'm more than willing rely on it, coupled with the fact we've had zero problems running their UniFi kit the past 4 or so years. The way our school is design/setup (as is the case with most older buildings I suspect) our main cabinet is in a damn awkward position and is a wall mounted one in a quiet area, so something like the 5400zl is completely out of the question, and as you say, crazy expensive.

My issue at the moment is that we're starting to saturate our 2G trunks between switches, and running out of physical switchports now that we're taking on things like IP CCTV, VoIP, access control in a school that was never really built with data networks in mind. Add on to this the AC WiFi upgrades I'm planning out, it's going to get very busy very quickly. In terms of L3 yes, I'm looking to do L3 everywhere; a) we have a complete mish mash of VLANs to do this already with L2 switches and b) it's not helping our uplink saturation. It looks like the 2920 series can take two SFP+ modules in the back, I suppose I could eliminate the Ubiquiti switch and use one of those at our core.

Hi Guys, I'm just planning out some big network changes for our school for next year, since we're finally moving to two tier in our county. I'm looking at purchasing: x1 Ubiquiti ES-16-XG L3 Fibre switch (our core) x3 HP 2920-48G-PoE+ for our access switches x3 HP 10G SFP+ Expansion cards for above switches x1 HP 2530-48G-PoE+-2SFP+ as a quieter access switch Which is great, I'm happy, and we can have L3 almost everywhere! Now I'm looking at sorting out Fibre SFPs and think I've got something but I'm not 100% confident with fibre gear, does anyone mind checking this over? At the moment I'm looking at using these for the Ubiquiti switch, and these for the HP 10G cards and 2530. Should these work together? Has anyone got any other recommendations for 10G SFP+ modules? Cheers

I think that was just poor sync on their video editing (usually people aren't actually using these products, it's fake), there's no way they'd release it with that much lag.

Reportedly it has a hybrid drive, no SSD. In this day and age, seriously??

If you're only using it for migrations/Hyper-V management then there isn't any need for it to be on a vSwitch. You might want to revisit networking in future. We have 4 NICs on each of our H-V hosts, I dedicate 1 to the host with no vSwitch, and then bond the other 3 on the host and physical switch with LACP, and tag VLANs at the VM level on one vSwitch.

I'd try not to multihome those either. Can you not route them across VLANs and open up any ACLs you have for those specific devices?

Just collected my phone from CPW on my lunch... Ahhh the anticipation is killing me, but I have to wait to get home tonight to have a play!

Holy necro batman!

As I posted elsewhere, we've deployed Ubiquiti's new UVC-G3 and UVC-G3-DOME cameras in our school and they've far exceeded my expectations. They aren't PTZ but the image quality is, quite frankly, amazing, even at night with the inbuilt IR lighting. We'll be deploying more in the coming months, including outside with the IR extender rings. They're all recording back to a Ubiquiti NVR with a couple of USB 3.0 disks attached to increase storage. Even if you're just deploying one camera, VLAN them off and apply QoS policies to stop your network traffic screwing with them! In terms of the ICO, yes you need to inform them and make sure you have well placed and visible signs telling potential visitors you're recording CCTV, and make sure you have the relevant policies in place. Also think about disabling the microphone if the cameras have them, video is one thing, audio is an entirely different matter and the ICO recommends against recording it if you can help it.

We use @Millgate, who resell Gamma by the looks of it.

Got this exact e-mail today I asked the girl in CPW where I'm having it delivered to and she reckoned we'd get a phone call tomorrow to let us know it's ready for pick up, despite the delivery date being Friday.

I wouldn't in place upgrade on our DCs or other servers, but 2008R2 > 2012R2 > 2016 has been smooth as butter on our Hyper-V hosts

This is correct, just bare in mind that if you shift VMs from host to host, the hosts must have Standard licenses assigned to them, and you can only move Standard licenses between hosts (on paper, not technically) every 90 days.

You do not need to install Server Standard on your Physical host. You can get away with using the free Hyper-V version (not sure why you would want to), but you're just eating your physical Standard license then. You can still stack Standard licenses on top of your Hyper-V install and keep using your x2 virtual OSEs per license. So you could do: Physical Hyper-V: -- x2 Virtual Standard installs This would need 1 Standard license. Physical Standard: -- x2 Virtual Standard installs This would need 1 Standard license Physical Standard: -- x4 virtual Standard installs This would need 2 Standard licenses and so on.

This is an important point to remember, all the UniFi gear can run without the controller running if you don't need the statistics or guest portal

Patching method all the way! We've been deploying the latest versions as they become available for the past 6(?) months or more on SCCM, no need to clean install. We don't use DPM, but AFAIK that doesn't have the new patching SCCM does?

Googled and googled, people seem to agree. The one pitfall is your Standard license is tied to the physical host. If you need to migrate VMs from one host to another you must have both physical servers fully licensed, or wait 90 days to transfer the physical license back to the original host.

Our licensing company specifically checked for us and told us that I could license x4 Windows VMs on one Hyper-V host using x2 Standard licenses. If we get audited I'll be pointing towards them and shouting not my problem, I guess.

SCCM and DPM are totally separate products you have to buy licenses for vs the Server OS.

Standard gives you x2 VM licenses and will license the hypervisor so long as the only role it is running is Hyper-V.

You will need to change your Datacenter installs to Standard to be compliant with licensing, even if you stay under the VM count. They're licensed as two completely separate SKUs with different roles/features/licensing models.

Been fantastic with our trolleys of iPads and Netbooks, handles the load very nicely

Same problem, gave up since documentation and troubleshooting was so scarce on the Internet :/

Even hot spares are getting a little questionable. With RAID rebuilds being the most stressful on healthy disks you want to make sure you have backups and do other bits and pieces before the machine starts rebuilding the array. I have to say though, we've only had good service from onsite engineers Dell and Lenovo have sent out to us. I wouldn't buy thousands of pounds of server without a minimum of 3 year NBD on site warranty. You try explaining why the £6000 server is now not working and out of warranty only 13 months in to management!
