You don't RAID with VSAN. VSAN handles redundancy and protection itself. If you have a RAID controller that does not allow "pass through", then create single disk RAID 0s for each disk.

CPU ready %s are fine during the day but too high during backups. I want to start to think longer term about stopping that. I've never really encountered a situation where backup operations cause CPU contention. Are you doing client-side dedupe or something?

I'm curious as to why anyone would to be honest, granted I'm no VMware expert or anything, but a properly sized VM to begin with kind of makes this pointless right? If in fact you do need to end up adding resources, surely the machine can be rebooted during a maintenance window. I'm having a hard time imagining a scenario where I need to add RAM to a VM on the fly. We do run pretty beefy clusters though and size our VM's for worst case scenario, so I guess if you are in a resource constrained environment it could come in handy.

EMC Networker is a wonderful backup solution  Yeah, hotplug and hot memory use the same amount of memory overhead as if you had the maximum amount of memory and cpu in the VMs. So a hundred of two hundred megs per VM wasted (or not wasted depending). To see overhead stuff build a VM with 2cpu and 4gb ram. Now make it 8cpu and 64gb ram. Adds on a bunch of overhead.

Hey nerds, I need some troubleshooting help. I'm pretty capable with VMware when everything is running, but when things break I'm not really sure which of the hundred log files to consult. Let me give you a bit of a  story because I am feeling kind of verbose. I just built out my new VMware lab box. I'm using the following NIC setup:  I had to monkey around a little, originally vmnic0 was assigned to vswitch0 and vmnic1 was unused. I flipped the nics this way because the realtek doesn't seem to support jumbo frames and the intel does. vSwitch0 is my management network, as well as my iSCSI network. vSwitch1 with the Realtek is only hosting VM traffic. So far so good I guess, right? So I deploy my VCSA OVA. Everything is working fine until about 5 minutes into setting up my VCSA I notice that I've lost connectivity to my management IP. What the poo poo. No PSOD on screen, nothing really wrong from what I can tell. I restart the host and since VCSA was configuring the database I figure I hosed that up so I delete it and redeploy. Sure enough, five minutes into setting up SSO or whatever step the web UI wizard is on I lose connectivity to my management IP again. What's odd is that I can still ping my VCSA, but the web UI is completely unresponsive. I reset the box and now I'm figuring something is seriously hosed up. I'm starting to suspect the Intel NIC since I could still ping my VCSA VM which is on the Realtek, but the Management IP is dead. I add a VMKernel interface to my realtek card and assign it a second management IP just so I can test my theory. Delete the VCSA, redeploy it, and sure enough my Intel IP dies about five minutes in. I point vSphere Client at my Realtek management IP and after a good long while I get into the machine. My iSCSI datastore has disconnected itself, which makes sense since it's on vmnic1 which has become unresponsive. So at this point I'm really not sure where to go. It's obvious I should pull the intel card until I can buy something better/newer, but I'd like to see if there are any logs to support this. I guess I posted a lot of text to ask which of the dozens of logs on the host I should be checking for network or hardware related errors? I haven't had a lot of time to play around with this because real life has been a little hectic, so I guess the more I can narrow this down the better. edit: To add to this, it's kind of weird that it only craps out when the VCSA is running because I've got a domain controller running on the same box and I don't seem to see any issues. I'll try to deploy another Windows server and see if it has any impact. some kinda jackal fucked around with this message at 00:01 on May 8, 2014 |

Marty, check /var/log/vmkernel.log. And feel free to share it, if you want someone to take a peek at it! I'm unsure which driver you'd have. ixgbe, e1000, or e1000e would be my guesses. You can find out by running "esxcfg-nics -l". Maybe see if you can find updated drivers, too.

Mausi posted:Thanks, maybe I should've phrased it as 'who uses Puppet/Salt/etc for managing their VM environment and what are your coding recommendations around it' to make it more relevant to the thread. We use Salt because I'm a python guy so the syntax of everything just made sense to me. Chef/Puppet seemed very complex, way more than I needed. Whereas Salt is moderately straightforward to start using, in an afternoon was able to get a full autoscaling aws system with salt + salt cloud with multiple state configs for my apps. Another even lighter weight option is Ansible.

I've an annoying problem with my lab setup. I got a eval copy of workstation 10 from doing the Stanley course and I'm trying to setup a pair of esxi5.5 vms in it. Even though I've added three network interfaces to my vm , the esxi guest will only detect one. I'm not sure if its this bug or something dumb that I'm doing. Anyone had a similar problem ? https://communities.vmware.com/message/2335268

If you install esxi with more than one adaptor added to the VM subsequent nics are detected as the wrong hardware type and don't work 0000:02:01.0 Network controller: Intel Corporation 82545EM Gigabit Ethernet Controller (Copper) [vmnic0] 0000:02:02.0 Network controller: AMD Inc PCnet - Fast 79C971 0000:02:03.0 Network controller: AMD Inc PCnet - Fast 79C971 To get multiple adaptors you must install esxi with only one nic added to vm. When that's fully working shut down esxi, add one adaptor to the vm, boot it up again. Rinse repeat until you have all your adaptors added.

Had I seen your post earlier I could have saved you the trouble but yep, I basically build the ESXi box, do the initial config and shut it down, then add the other NICs.

No offense, but I don't think I'd ever want to install ESXi from some image that a random dude on the internet is hosting. I'd rather just get it straight from VMware with the HP/Dell stuff pre-installed and not have to worry about "is this the latest version?" and "I hope he didn't mess it up" and "I hope he didn't get hacked and now there's a rootkit".

So while I'm on the subject of my lab: http://www.ebay.ca/itm/IBM-PRO-1000...8ddd6cab&_uhb=1 ESXi 5.5+ Y/N?

Does anyone have any anecdotal best-practices for doing Windows Server Failover Clustering (WSFC) on VMware? We're running around 10 clusters with 2-3 nodes per cluster and some work perfectly yet others are a dogs breakfast. All the nodes are running Windows Server 2008 R2, clustered disks are presented directly to the VMs via iSCSI and the only clustered applications are MS SQL Server 2008 R2.

One of the sales guys came to be with an interesting idea today that I don't think is possible, but we'll see. He he has a client that has a number of low/mid/high tier FC storage systems, some nonames, some 3par, etc. He wants to create a vSphere VSAN cluster to act as a front end for all of this storage. 60% of the hosts attached to this storage, about 6-8 different storage systems, all of different types, are ESXi of some sort, but the remaining are physical boxes, mostly oracle DB servers. His plan is to somehow create LUNs on the vSphere VSAN that can be presented to the physical devices through the FC network. I had not heard anything about this with the developments of VSAN, so I'm skeptical, but I really only deal with our IBM V7000s so my storage experience isn't very widespread. I had suggested some kind of storage visualization appliance, like the IBM SVC, but cost is a big factor so they're trying to do this on the cheap (big surprise.) Any ideas if there is any substance here? EDIT Definitely not possible. Virtual SAN supports only SATA, SAS HDD, and PCIe storage. You cannot use storage attached through USB, Fibre Channel, or iSCSI. mattisacomputer fucked around with this message at 01:00 on May 14, 2014 |

That said, if I wanted to implement this on an enterprise level, I'd probably want the quick and easy download.

You would need to perform a Physical to virtual migration of your OS first. You'd need to look at hyper-v. IIRC windows 8 has a pretty cool intergration with going virtual.

Super dumbo question here. I'm following the 70-640 exercise for setting up a vm in VirtualBox so its consistent with the rest of the exercises later in the book. I'm doing this on my work laptop which is connected to the office network. When it tells me to assign a static ip of 10.0.11 I probably should pick something 192 instead? Or will my laptop perform some NAT wizardry and the network won't care?

Anything special to note when doing a vCenter upgrade where View is involved as well? I took over a two jacked up vSphere/View environments a while back. One was 4.1 and one 5.0. Got everything moved over to the 5.0 environment and then got View upgrade to 5.3. Now looking to get vCenter upgraded to 5.5 so I can get my hosts updated as well. I am throwing together a little test environment now to do a test run on the vCenter 5.0 to 5.5 jump, but not sure if I should build a little View lab in there as well (probably should...).
