Alright so our 35 man business has no sys admin or really even an IT guy. We've gotten by (against my constant requests for an IT employee) but just contracting big things out from time to time and then several of us just handling help desk poo poo. It's the worst system. Anyway we have 2 main switches, Dell Powerconnect 2824. Everything works fine but we just added a new QNAP NAS and it's got four ethernet ports. I'd like to trunk them together for better/faster access for our designers (who currently connect to an old rear end QNAP NAS via single gigabit ethernet). Problem is our switches are basically full up. So I'm guessing the easiest thing is just to add a new one. They're cheap as poo poo now. Looks like the 2824 are the smallest version with a link port. So I'm guessing I should grab one of those and just use the link ports to link it up and then plug the 4 QNAP connections directly into that?

Sounds like you might want to get a 10Gbe switch, maybe connect the high bandwidth stuff to it. I bet the Qnap can get a 10Gbe interface card as well.

We use 10Gbe for all of our video editing stuff and it's a loving dream. But that's all PC stuff. The designers all work on Macs and the cost to get them 10Gbe equipped (and then rewiring all of their cable runs) is way too much at this juncture (goddamn motherfucking iMacs I swear to god). So we're just looking to get them a little bit of speed boost in the existing environment.

You go at the speed of the slowest device, so if they are on 100Mbit it doesn't matter if you trunk a bunch of ports you are still getting 100Mbit per mac. You can use a single 10Gbit to serve 10 different macs with 1Gbit connections just fine. If you are thinking of getting the macs 10Gbit in the near future you can install the switches now and upgrade the rest later you'll still see improvements.

They're all gigabit macs on gigabit lines. My concern isn't the speed per individual mac necessarily, but rather that they all are accessing a server with a single line and bottlenecking it. So trunking the 4 lines will help disperse the load and serve the macs faster. Is that incorrect? (It may very well be since I'm not a sysadmin, I just figured that about 8 macs trying to access a single server with a single gigabit connection might bottleneck it).

Calculating storage network bandwidth requirements is more in-depth than "Computer Gigabit, Storage Gigabit, Have Gigabit traffic." E: That sounded snarky. Isn't meant to be. Generally just trying to tell you you're gonna be just fine plugging in one port, maybe two for "Oops it broke" or whatever. There's no reason to buy a whole separate switch, especially not 10Gb + the add-ins for the qnap just to feed a couple of iMacs. E2: Also please consider that if you aren't going to lag your new switch to your existing infrastructure, your switch to switch uplink is still capped at 1Gbps.

It wasn't snarky don't worry! And yeah I'm not doing 10Gbe (which I think I mentioned later on) because it's too expensive... not just for the switch but getting iMac the adapters and then runnin' the cable. F that. I was only ever looking at spending $50 on an extra Powerconnect 2824 switch (which is the lowest model with the SFP port to connect the switches). However I didn't even think about the disk I/O (obviously I'm not a sys admin). It's this NAS: https://www.qnap.com/en-us/product/ts-877 with Seagate Ironwolf Pro 7200rpm disks in it and I was going to put a couple of 256gig SSDs we have laying around in there too.

You might be able to set up an SSD cache but that wont help if they are constantly changing what files they access since it can't act as a cache. What happens is the RAID goes at the speed of the slowest drive and I've been told but never bothered to confirm that "bad things" happen when you mix 5400 and 7200RPM drives. A RAID is also equal to the smallest drive size times the number of disks (and there's usually a reduction in size because of mirrors or parity, which you DO want).

I'm not mixing anything - those SSDs are only for cache purposes - not for mixing in the general volume. The general storage volume is just 6 of those same Seagate drives.

Yeah, based off the rest of your information I'm still going to go with "You're gonna crush the NAS before the network pipe". If its cheap and you want to do it for fun and the experience of it, go wild, but I don't know that I'd try to justify it with performance gains. I'm not 100% up-to-date (E2: Im actually 0% up-to-date because I can't remember the last time I even touched qnap storage) on how QNAP is doing SSD based read/write caching these days, but I wouldn't hold my breath that its going to make a huge difference. E: I decided to take a look at one of my customers Equallogic setups (please dont buy equallogic storage, ty) for bandwidth usage since it's the closest thing I have comparatively. It's a R1+0 array of 10k drives and they're using it for hypervisor datastores. The disk is trying to keep up with read/write load, and the entire array is using less than 1Gbps of its 10Gbps uplink on average. Anecdotal as I don't know your actual workload over there (and block data transfer vs. file data, etc.), but maybe adds some perspective for you. In almost every case where storage connectivity is concerned, the disk will stop providing available throughput before the network connectivity will.

What RAID level are you in? I'm going to go with RAID10, which is the fastest with parity, though most places will use RAID6 even when they need performance. If it's on RAID0 you lose 1 drive you lose everything. That will happen, so if you are on 0 you need to replace that quick and don't bother to calculate speed. So I'm using this very accurate (it's not) calculator https://wintelguy.com/raidperf.pl Using 100MB/s which is faster than the sequential read rating on the recommended settings for 7200 you only get 400MB/s for RAID10, you probably have RAID6, which is only 175MB/s I'm mostly doing this to demonstrate how important your RAID levels is. This calculator is theoretical, and makes a ton of assumptions. It should be accurate enough for comparing "Manufacturer claims this is the throughput at this RAID level" vs "Other manufacturer at different RAID level". An 8 drive RAID10 will be the same size as that 6 drive RAID6 and even faster than the 6 drive RAID10 because the bigger it gets the faster 10 gets. (It's up to 533MB/s). Again this is sequential and no where close to real world performance, random read / write is about 1/3 the speed but we don't even know if the MB/s represents your drives. Again do not use a calculator like this if you have a hard requirement on throughput.

Thanks for all the info guys - good stuff. Def was never going to do RAID 0. The old storage is RAID 5 and I think our VideoStorage (I didn't set it up) is either 6 or 10 - no idea. Looks like I'll just keep with a single pipe! Makes it easy on me!

I feel like in this day and age of cheap storage, I feel like RAID 5 is largely obsolete; I cannot imagine a set of data you care enough about to want to RAID, but don't care enough about to spend more money than RAID 5 requires.

RAID5 still has plenty of life in it as it isn't nearly as space-wasteful as R1+0, is perfectly suited to average IO loads from anything that isn't database intensive, and write caching in most enterprise level storage has been sufficient to cover the performance deficit for quite some time now. On top of that in addition to the parity drives in the raid set every single modern enterprise storage appliance keeps hot-spares on deck per X number of like disks in an array. The chance of data loss due to drive failure on an R5 is pretty much non-relevant. R5 is usually the correct choice for hosting your guest OS disks, average-load operations for application servers, DFS rollouts, etc. R6 is for LTS. R1+0 is for either performance purposes where you can justify the configuration over R5 or you have a real budget and can afford to just spend the extra $$$$ on the optimal configuration. Storage being cheap is also perspective. I consider $100,000 - 150,000 to be a "cheap" unit. For probably 95% of the people in this thread that is more money than they will spend on their entire network as a whole during their tenure. For some people a $150 3TB USB 3.0 drive from Best Buy is "cheap", and I've met business owners who think that is too expensive for this computer stuff. E: Also outside the scope of this thread for most of its tenants but there is such a thing as storage with multiple arrays :P E2: I say "Enterprise" storage but I consider that based on feature set, not cost. You can get entry-level enterprise storage arrays for $40,000-$50,000 if you dont need a ton of up front space. Not outside the realm of purchase for a good chunk of SMBs.

By hosted do you mean cloud or on prem? If it's their cloud solution we just ditched Mitel Cloud because they sent techs out 3 times each time they said the network was fine and everything should work then sent us a bill for the tech. It was a battle each time to get it removed since the tech admitted fault each time. We were having basically the same issues. If it helps they are using ShoreTel for their cloud since they bought ShoreTel.

If your ISP isn't respecting QoS flags to the Mitel cloud and you're not completely hammering your LAN or firewall, then QoS likely isn't going to help.

For this very purpose I bought a Force10 fiber switch, four Mellanox ConnectX-2 HBAs and eight 10g transceivers for my lab. It was fun to mess around with in my ESX environment with a stretched vSAN and I learned a lot. That said, I do not recommend using any eBay gear in a production environment because there is no guarantee on the reliability of the gear and no warranty and no support. But it’s cheap way to get access to technology (albeit five year old technology) for proof-of-concept and learning potential.

All the servers were in building 1, as was the internet connection, so the phones had to contend with LAN file transfers and internet use even internally. If you have access to the phones' web interfaces I can give you some ideas on how to possibly make a pair of phones support directly calling each other IP to IP, which would allow you to conclusively test LAN performance.

Same-ish. I've never had cause to implement any kind of internal QoS for voice traffic. If your voice and data are separated appropriately and your uplinks aren't archaic it shouldn't be an issue. Especially not with the user/phone counts most SMBs will have on site. You may want to research the phone model and as suggested above see if the phones support peer to peer direct connections rather than routing internal calls through the hosted service.
