Sorry I missed the disconnected state somehow. Are you able to connect/login to the host directly instead of vCenter Server? If yes, you should be able to delete the snapshots this way.

Vmdk cloning of Centos server stalls (SSD to NAS)
Hi
We recently moved our Centos/Cpanel server to an SSD drive.
We use vmkfstools to clone the VMDK for backup purposes.
However the process stalls at 80% for 30 minutes and continues to finish sucessfully.
If the target is a local datastore then it finishes the cloning even with the stall at 80%
But if the target is a nas, then it failsshortly after the stall.
It is only since we moved to the SSD drive that this cloning problem started.
Any ideas?

SDRS with User Overide
Hi,
I want to ask if the SDRS in vSphere5 will give a user ability to put VM VMDK on specific Datastore , if a specific ORG. policy require that some VMs must be on specific cabability datastore (Ex: Teir1 VM must be on datastore that are very fast and provide RAID10). or when SDRS compined to Profile-Driven-Storage.
if SDRS allow that , how it can be configured on SDRS console ..
Thanks & Regards,
Fady

Question on the proper way of implementing network connectivity.
Hey guys-
I've read some articles and the configuration guide numerous times on this practice, but I can't seem to figure out what the "proper/best practice" way of implemeting the network aspect from the VMware Host to the Switch. This enviroment is my lab environment, FYI.
Can someone please shed some light on this. I've been following this - http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1004127
My scenario is:
- 2 ESXi Hosts running 4.1
- Each host is the same hardware
- Each host has 2 NICs
- Both connected to a single 3560 (though 2 are available)
- Each host connects to a SAN (running OpenFiler) over iSCSI
- 5 VLANs are involved
- Both hosts in vCenter in a non-Clustered environment (for the time being)
- So, should each host connect to the switch as a trunk or an access port?
- If trunking is the method, where is the tagging performed? At the switch, or within the vSwitch on each host?
- How do you know when to choose to trunk or not to trunk?
- Does each host have to have 1 vSwitch for VMs and a separate vSwitch for the iSCSI connection?
- Should the 2 NICs be teamed from within VMware to the switch? Or should they should be a port-channel on the switch? Or none of these options.
I'm still a newb to the VMware line, so I'm just really practicing a lot lately. Any help is greatly appreciated.

Re: Question on the proper way of implementing network connectivity.
- It's easiest to trunk the ports.
- The tagging will be done within the vSwitch on the port groups.
- If extra security is needed, you could not trunk.
- You don't have to technically, but it is extremely recommended to segregate regular traffic and iSCSI traffic.
- It's easiest to do the load balancing within the vSwitch, but you can do it on the physical switch. There are certain requirements when doing etherchannel on the switch. Check out the networking guides for more details (e.g. http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1004048)

Re: Swap File
Thank you for quick reply. Just so I understand, if a a VM is set to 2GB of vram and the VM actually needs the 2GB, but the host does not have 2GB free to give the VM, that is when the swap file is used?
That is correct -
In regards to page file, should I assume if page file is being used, VM has not been configured with the appropriate amount of vRAM? Is there an easy way in vSphere client or on guest OS to see this?
I would not necessarily say it is sized incorrectly because a machine, virtual and physical, will constantly be using its swap file and the swap file might be used for momentary spikes -

Re: Question on the proper way of implementing network connectivity.
Hey Earl-
Thanks for the quick reply and the help!
3. What do you mean for the "extra security", I could not trunk?
4. Thanks for making sense of that, I've been confused on that. Does this "recommendation" change if you go from a vSwitch over to DvSwitch?
5. During the load balancing in VMWare, are both of the NICs being used at the same time or is one being put on "standby"?

Re: Slow Disk I/O Performance (CentOS 5.8 Guest 64 Bit)
What kind of disk stats are you seeing within the performance tab within the vSphere Client (latency, etc)? Are you using the same type of virtual hardware on new and old? Same hosts?

Re: Question on the proper way of implementing network connectivity.
3. For example, if you wanted to limit what the host could access network-wise.
4. If you switched to 10 gig, vDS, and network I/O control, you could get away with using the same links. Otherwise, you don't want your guest traffic fighting the iSCSI traffic.
5. Check out this guide on how the load balancing policies work: http://www.vmware.com/files/pdf/virtual_networking_concepts.pdf
The above doc hasa lot of other good info in it, as well.

Re: Question on the proper way of implementing network connectivity.
3. Essentially, couldn't I just limit the allowed VLANs over the trunk at the switch level? Or would this be difference than configuring the switchport as an access port?
4. That makes perfect sense. I tried merging my 2 vSwitches and then running 1 vDS with both the iSCSI and network traffic inside and it was just a mess. I wasnt able to understand why at the time, but now that you said this - it makes a lot more sense. So should the iSCSI always have its own dedicated NIC card and VLAN (if lower than what you just stated)?
Thanks for the read, will review tonight. Thanks for your help!!

Re: HTTP 404 and HTTP 500 errors - resolved, need WebDav ports open between TAF & vCenter
Thats great to hear - we do same some wiki-based internal documentation on ports/comm/arch - I'll dig those up on Monday and see if anything is covered regarding WebDav - if not that would be a good place to start in putting together some documentation on the ports required. Thanks for posting the solution for all - good to know.

Re: Slow Disk I/O Performance (CentOS 5.8 Guest 64 Bit)
I have not checked the disk performance average in vsphere lately.
I am using the same hardware, same hosts, only changed the datastore to ssd.
At the moment the ssd datastore one hour average write latency is 1.3 and read .7 ms.
11:00 Sunday night here, not much activity on server at the moment.
Should have better stats in 12 hours time

Re: help with build and edit Recipe
SetOption is an exe that you'll be able to find the c:\ root of the capture VM. Its a tool we use to populate package.ini settings. The syntax is like this:
Usage: setoption Section Key Value IniFilename examples for use are 1. setoption BuildOptions QualityReportingEnabled 1 .\package.ini or 2. SetOption.exe BuildOptions SandboxName "$SANDBOX" "%ProjectDirectory%\\package.ini"
If you wanted to make a Recipe for Horizon enablement, the below would do it. However, as I'll post in a blog/vid later this week. You should go to settings, configuration, put the check on integrate w Horizon, then supply an activation code and the url of your Horizon web service. Once you do that Horizon activation is automatically created as an option when capturing and when rebuilding from existing projects. So for now, use a recipe if you like, for the future do the Horizon integration config as it will automatically populate the Horizon App Catalog.

Re: Question on the proper way of implementing network connectivity.
3. Yep, but some companies like to give that security control to the network team instead of the VM team. I would say just trunk, but I'm sure there are edge cases.
4. Yep, I would segregate the traffic by giving iSCSI it's own NIC ports, and also separate iSCSI traffic to its own network at the physical switch level instead of just VLAN.
You're welcome. Good luck!
