      I don't know how Starwind vSAN can be run but if it's on a hypervisor it's severely limited by I/O congestion through the kernel. NVMe drives is causing problems that was of no concern whatsoever with spinners. Both KVM and Xen has made a lot of work to limit their I/O latency and use polling techniques now but it's still a problem. That's why you really need SR-IOV on NVMe drives so any VM can bypass the hypervisor and just have it's own kernel to slow things down.

      Anton: There are no problems with polling these days 🙂 You normally spawn a SPDK-enabled VM (Linux is unbeatable here as most of the new gen I/O development happens there) and pass thru RDMA-capable network hardware (virtual function with SR-IOV or whole card with PCIe pass-thru, this is really irrelevant...) and NMVe drives and... magic starts happening 🙂 This is how our NVMe-oF target works on ESXi & Hyper-V (KVM & Xen have no benefits here architecturally, this is where you're either wrong or I failed to get your arguments). It's possible to port SPDK into Windows user-mode but lack of NVMe and NIC polling drivers takes away all the fun: to move the same amount of data we normally use ~4x more CPU horsepower on "Pure Windows" Vs. "Linux-SPDK-VM-on-Windows" models. Microsoft is trying to bring SPDK to Windows kernel (so does VMware from what I know), but it needs a lot of work from NIC and NVMe engineers and... nobody wants to contribute. Really.

      Just my $0.02 🙂

      @NashBrydges That's most likely direct connection. Plex uses UPnP and NAT-PMP to open ports on router, otherwise you simply cannot connect directly. If you stream through relay, that's where limitation is in place.

      I have UPNP + NAT-PMP enabled. I'll disable them and test things out when I have a chance.

      @EddieJennings I would start by using oVirt Node (it's based on CentOS), it's the simplest, least hassled way of setting up.

      Yeah, they have their own Node deployer, I'd generally just use that.

      Do you have a card swiper / chip reader so you can process payments directly?

      Yes. I've been using PayPal Here for a few years with great success. I'm just looking to improve the process of collecting of order information.

      Wouldn't it be better to have the customer enter their info with their own phones instead of using your ipad? I assume you get the orders at the same time more or less.

      Possibly. And yes, orders and payment happen at the same time. At these events orders are about 60% credit and 40% cash transactions.

      Where IT Consultants fit between Vendors and Clients

      @EddieJennings said in Where IT Consultants fit between Vendors and Clients:

      I don't recall saying consultant vs non-consultant, but the responses in the thread have addressed the question of who should interface with a vendor.

      I feel like I should provide some context for how some vendors operate to get a better idea for the level of vendor involvement and who the vendor wants to work with.

      Few things....

      It depends on the vendor, and who the customer is. For instance, some vendors are 100% channel sales (Datto I think fell in here) and a customer outright can't buy them directly.

      Most larger vendors DO NOT WANT to talk/sell to smaller customers directly (It's too expensive, as they pay too good of benefits, and too high of compensation to their salespeople to scale down to small accounts that because they only sell their products can't form a meaningful relationship). There typically are 4 "buckets" for products.

      a. Retail sales for VERY low-value non-complicated sale items that a website can sell. These products don't require sizing assistance or are pretty simple. Think an ethernet patch cable.

      b. More complicated items on smaller deals that intend to be 100% channeled in sales (You don't want this stuff sold by Amazon as the customer will likely buy the wrong SKU, or screw upsizing). Note, the vendor may offer a direct model but will often have "cannon fodder" class salespeople in this space, and generally will even charge more for going direct. A VAR is your best bet here. Think someone buying 3 servers, or 20 laptops, or a single palo alto firewall for a SMB. all services are going to be VAR partner led when possible beyond post-sales support escalations. Also in these smaller accounts it's expected that the VAR/MSP is more than likely going to know the needs potentially better than the customer does.

      c. larger enterprise deals where the VAR is still involved but the vendor takes some leadership because the account is big enough to matter, or the vendor wants a strategic presence in this account. The paper may shift to being run by the vendor at the higher end of this, with a small revenue share back to the VAR who brought this deal to them for the life of this deal. Think ELA's, 100 site MLPS circuit deals etc. services might be delivered by either the partner or the vendor at this stage.

      d. Direct only deals. These are sometimes called "named accounts" and the vendor will 100% run paper directly. A partner of record might get 3% of the deal if they are lucky, or be subcontracted if they are a marque support partner with tons of certifications.

      Others can comment but sales teams tend to be organized around these different groups Example:

      Commercial-1 Smallest accounts and people who haven't bought anything in 5 years from you. These are called "Whitespace accounts" and you basically have people trying to get a meeting with hundreds of these in a territory or verticle and seeing if they can find some gold and get people with a low priced entry solution. ALL sales will be inside teams at this scale with VAR's or MSPs type shops doing any in person meetings.

      Commercial-2 Slightly larger accounts. Might have spent a few thousand, but there isn't a strategic or lucrative relationship. You might have a field team at this point but they will likely cover hundreds of accounts still.

      Midsized Accounts - Still larger. They will likely have some clue who their account team is, but still rely on a VAR for most day to day stuff.

      Large Enterprise - Big names you recognize. These accounts will have teams who might have only 5-10 customers. Alignment on this is going to be tied to geograhpy still more than likely.

      Globals - Account teams will be in some cases 1:1, or if there is a specific industry (Say automakers, or oil gas) you might have a team in a city (like Houston) whose job is to wrangle these guys. The Cxx levels of the vendor likely have strong relationships with these accounts and for a software vendor these accounts could be spending 9 figures at a time, or for hardware companies 10.

      @scottalanmiller said in Infrastructure Needed for Hypervisor Cluster:

      Clustering is done when the cost of clustering is low versus the risk of not clustering.

      I would change that slightly to Clustering is done when the cost of clustering is low versus the cost of not clustering. A risk is always a cost, but some costs are not risks. For example taking down a hypervisor for maintenance vs moving guests to another node and taking down a free node for maintenance.

      Sure, using risk cost vs investment cost as cost v cost is a perfect valid way to look at it. I use that all the time in the opposite way.

      You can say that risk is a cost. Or conversely, you can look at the clustering cost up front as essentially a "financial event" similar to an outage.

      I'm create a template VM for Server 2019 (one with and one without the GUI). I'm curious to see if any of you have seen the following behaviors.

      Non-GUI

      Use sconfig to download and install updates. Choose All updates, download, and install. After notification the updates were installed (appears about 5 seconds after choosing to install), you're prompted to reboot. After reboot, check for updates again to find the same updates still listed, repeat from step 2 endlessly.

      GUI
      Updates stay forever at "pending dowload"

      GUI and using sconfig
      Same behavior as using sconfig in the non-GUI environment.

      Nope, you got something weird going on.

      Perhaps, such a behavior is OK (zmconfigd fetches configs,checks them for not being changed and assumes no restarts needed for services)?

      I think so. Nothing in there suggests a restart happened.

      @Dashrender said in Companies that use a Linux distro on workstations:

      I ask - does saying Linux really matter though? Isn't it much more important to actually list the distro? At least the OP asked specifically Linux Distro.

      Which is why I listed the specific distribution and desktop. imo, it should always be linux as it is a generic term. Kind of like Windows, which one?

      I read your statement like this "it should always be linux as it is a generic term.

      HUH? so which side are you on?

      Personally - I think the term linux should be dropped by everyone (well at least by 99.9%) because it's nearly meaningless.

      Asking if something runs on linux is meaningless. Asking if something runs on Fedora or Ubuntu has meaning - because you know the actual OS you'll be running them on.

      the generic nature of 'linux' is one of the most confounding confusers for laypeople. We should just drop it. it doesn't matter. We never talk about the Windows Kernel, or the Mac OS Kernel - We talk about Windows 10 (OK, we're starting to run into a problem here too because there are 7 versions of Windows 10 - and the same can be said for Mac OS). But if we drop the word linux, people can start talking about Fedora or Ubuntu, etc and suddenly the world becomes a smaller, much more manageable place.

      Actually Linux should mean the same as Windows or MacOS anymore as you pointed out.

      What specific build is what matters. W10R1510, W10R1809, Fedora, MacOS wtf ever those are called.

      No - I disagree - Linux isn't like Windows or MacOS at all - Linux is not an OS - Windows/MacOS are OSes.

      If you say, runs on Windows, you can be pretty damned sure it's going to run on Windows 10. if you say it runs on Linux, you have no clue if that's Fedora, Ubuntu, etc. And while we might be able to get it to work, the layperson would never even try with the requires to get onto a linux Distro it's not designed for.

      Actually if it says runs on linux, it will run on pretty much all of them.

      The developer may only provide binaries or packages for certain specific distros. But if it builds on one, it will build on pretty much all of them.

      I gave you that out already - but I also said - normals will never do that. Which is the whole purpose of my comments... it's about normals, laypeople. Not IT pros.

      people like me !
      Well worse than me I guess.

      You said meetings with potential clients. That sums it up, you're trying to sell them something, so you don't bill for that.

      You also don't give away any consulting or "answers".

      That's something I, or anyone else, would have to take care to avoid. I could see someone getting carried away and end up trying to design a solution before an agreement is reached.

      I've seen that happen a lot. Even people implementing the solution for free. With nothing whatsoever left to pay for at the end.
