Does the thread have any recommendations for 10GbE switches that aren't stupidly expensive? We're trying to build a warm failover environment with physical hardware redundancy. Our storage vendor prefers to do this with direct 10GbE links between the hardware, but that only works with two storage node and one VM node. With two storage nodes and two VM nodes, we need a switch involved. Most 10GbE switches that I can find are way, way outside of our price range. Like, we could add two more VM nodes for as much as one costs. The only affordable one I've found is the Netgear XS712T. I have no experience with any of their managed equipment.

10Gb is great but a lot of 10Gb is with converged networking, and cost per port. I'd be interested in your setup actually, I'm a bit puzzled. Are you doing some SAN based replication?

Not sure if this is the right place to put this, but I'm having issues with my vSphere Client in my homelab setup on a ESXi Whitebox. It's been easy as hell to setup and you all have been very informative in this thread (and others). What I have done so far is very minimal such as setting up a Windows Server 2012 DC or 2 with WSUS and such... no vCenter, nothing like that. I recently tried setting up Veeam on one of my Server VMs which worked fine until I started getting these odd crashes. I'm not sure if it's connected to Veeam at all (it shouldn't be?), but now the vSphere Windows clieent is crashing with the following errors: http://i.imgur.com/wAEKNN5.png and then the Event Viewer log is showing: http://i.imgur.com/Zb08pol.png. My vSphere client log is here: http://pastebin.com/wK9g2TWw. Basically Runtime errors connected to the Remote Console Plugin? I'm not sure how to troubleshoot it past that and my Googling and discussions in #vmware aren't getting very far. I've even made a new Windows 8 VM (on my local machine using Workstation) and loaded up the vSphere Client thinking it was going to work fine (and it be a local problem with my machine) but it also crashed with the same error. Even when I'm not consoled into any VMs, it crashes... and it seems as if its fairly random when it happens. When it crashes without any of the consoles open, it only gives a "server no longer valid" error. I'm really at a loss of what to do besides just wipe my ESXi boot drive and start from scratch... figured I would ask for some advice before taking that step. dox fucked around with this message at 00:06 on Oct 31, 2013 |

Basically, we'll have two VM hosts, each of which is capable of supporting our entire infrastructure, but we'll be dividing the day to day load between them. The storage is Nexenta, so ZFS-based. My understanding is that it keeps a rolling log of changes made to each block and can transmit the log to other machines. It's not real-time, but our use case doesn't mandate real-time. In the event of a disaster, it's acceptable for us to lose a minute or three of data. I know that GbE is expensive, but it seems that everyone's hiding their 12, 16 or 24 port hardware. I don't want to buy some 48 port behemoth when I need less than a dozen.

I CJ for like 20 users spread over 3 different physical locations, most of which are running POS software on very old computers running XP. Since Windows XP is nearing the end of its support cycle, I'm exploring our upgrade options. I use RDC (locally and remotely) to fix poo poo when it breaks, so I have a little familiarity with this virtualization stuff. Aside from the obvious solution (deploying a bunch of new computers) I'm exploring a thin/zero client configuration, over gigabit ethernet, with a server for each physical location. Our POS software is a dot net application with pretty minimal requirements, and each user needs web access to a few specific lightweight webpages. Three questions: 1. What server version of Windows would be good to host like 12 of these clients max? 2. How snappy is the user experience... Like, is it laggy like Remote Desktop Connection can be sometimes, or is it pretty smooth? 3. While we wait for a native tablet version of our POS software, might it be possible to use a Surface as a thin client? a_pineapple fucked around with this message at 22:14 on Nov 3, 2013 |

VSphere question: I have 2 vsphere hosts with 2 x E5-2650s and 64GB of ram each. I have been given the approval to buy (badly needed) more hardware. I want to do two things. One, I have an application that needs pure MHz. I want to get E5-2643 v2 (6@3.5ghz). I also want to add more regular hosts for our general vSphere pool. These I would prefer to upgrade to the new v2 Ivy Bridges as well. Is there a penalty for vMotion or anything besides FT (which I don't want to do) if I don't have 100% identical hardware? I can separate off vsphere/vcenter clusters if necessary as the application that it is hosting is 100% justified for the demand but it would not be ideal. Basically, how homogeneous does vSphere need to be?

Read up on "VMware EVC". Basically your hosts will be set to the lowest common denominator in terms of CPU features that are supported by every host in the cluster. This might be totally fine, or might totally crap on the performance of that CPU intensive app if it relies on an instruction that only exists in very new CPU's. Also you can't vMotion between Intel and AMD hosts but it doesn't sound like you were considering that anyway.

vas0line posted:I CJ for like 20 users spread over 3 different physical locations, most of which are running POS software on very old computers running XP. Since no one has bit on this yet, I'll give my 2 cents. Strictly speaking, using Remote Desktop to do remote work is not virtualization. Doing VDI for 3 separate offices would be be a tremendous outlay of capital and hardware for very little gain. For that number of machines, I would consider buying all new hardware and just make an image to deploy to make the upgrade easier. Another option would be using terminal services server at each location (or a central one if bandwidth between locales is good). A Surface Pro is literally a laptop that can run any app. The Surface is an ARM tablet that only runs Windows RT (or whatever they are calling it now) apps from the MS store.

What's a good resource for VMware licensing? Right now we have a 3-node cluster of Xeon E5335's with 40GB of RAM running vSphere 4 Advanced, and then a 2-node cluster in our disaster recovery datacenter. We plan on going up to a pair of 2-node clusters of Xeon E5-2670's with 96GB RAM. Would our current version of VMware be compatible? My boss thinks we are 'under maintenance' so we could upgrade to whatever the current version is, for free.

There's plenty of other vendors out there, that's just one of the cheaper ones that I trust enough to recommend. I wouldn't let vendor animosity steer you toward a 'prosumer' grade switch like a netgear. A cheap switch will likely cause your major headaches.

That's what I've done in the past when coming into an environment where the licenses were a total clusterfuck and no one knew the status of our support contracts or even what licenses we owned. Your boss is probably right, for once. As long as you have an active service and support contract with VMware you're entitled to upgrade to the latest version (of the same edition, of course) for free.

This question's probably aimed at evol262, but here for anyone else as well: We've got some junky vendor Windows application which they seem to tie to the UUID accessible via PowerShell in the win32_computersystemproduct WMI object, which is linked to the IdentifyingNumber in that same object (pulled from CIM_product apparently). As an example from a random VMware VM in my infrastructure: code:On the VMware side, this UUID is specified in the vmx configuration file and shouldn't ever change: code:On that machine, the UUID seems to fluctuate periodically, which breaks our vendor software. Checking the same WMI object on that server: code:

They're probably migrating your machine around without using libvirt with some script that calls qemu-kvm without a -uuid parameter and you get poo poo on with whatever random UUID it generates. libvirt sets it in the VM XML file by default. They absolutely have the ability to control this.

Is it possible to set up some kind of virtual machine I can connect to while the host computer is being used? I have a laptop and an iPad. The issue is that there are some simple apps I want to want to run on the Laptop while my wife is also using it. Apparently consumer versions of Windows don't allow you to have two sessions concurrently so I can't just use RDP.

I stopped receiving emails from our vSphere Data Protection appliance in the morning, so I logged in today and it was slow as hell (though backups were still run the night before). I decided to reboot the VM since it was acting so weird, and now it's stuck on "Starting VDP appliance systems. Estimated time to complete: 10 minutes." It's been stuck like this for half an hour now. I'm thinking of just scrapping the VDP install, and starting fresh with a larger image (we used the 0.5TB one before) so I figured I'd go for the 1TB one. It turns out there's a new version of VDP (5.5.1), but it doesn't have different ova files for different sizes. So first question: most of our environment is on 5.1 right now. Should I just download the 5.1 1TB ova for VDP, or am I better off going ahead and getting the latest? If I'm better off going with the latest, what happened to the different sized VDP tiers? The one that's listed is "0.0TB" does this mean the image is variable now, and I choose a size as it installs?
