vCD Architecture Scale-Out

May 12, 2019, 10:54 pm
$

Hi all,

 

I'm looking at deploying a vCD environment, initially starting with just a single cell and single RabbitMQ server to gauge actual demand/use of vCD functionality. I will be using the 9.7 appliance with an embedded PSQL database. An external NFS transfer server will also be deployed. No load-balancer required as yet since we only have one cell anyway.

 

My question is can we build out an environment at a later date when we actually need to expand? For instance, deploy a single cell now and expand to 2, 3, n-number cells with a load-balancer in front. Can we do the same with RabbitMQ too? I can't seem to find any information regarding cell/environment expansion. It appears that the vCD architecture is designed to support scaling-out but just wanted to confirm.

 

Thanks for your time!

Hi Kam,

 

Yes, this is possible with the appliances. However, there are a few caveats:

 

1. There's a known bug right now on the 9.7 appliance with SSL certs. There will be a patch available soon, but this limits the use of H5 client without a load balancer and single cell. Workaround is to utilize a load balancer, which is always used for production deployments.

2. RMQ is not included in the appliance, so I presume you are manually installing it post-deployment. If that's the case, carry on.

3. The single appliance OVA has different roles and you can always expand the cell and/or PgSQL role.

 

Hope this helps,

vCD 9.x + CassandraDB and detailed historical metrics about HardDisk (when VM have different storage profile attached to every disk)

Hi.

We are using cassandra DB with vCD 9.5 and 9.7 in our environments. I think this is know problem but.

 

How configure cassandra to collect performance metrics about specific disks and VM.

Im speaking about situation when EXAMPLE: VM is on GOLD storage, HardDisk1 is on GOLD storage, HardDisk2 is on SILVER storage and HardDisk3 os on BRONZE storage...

According what we know now we can only grab metrics for whole VM and we can't now detailed  charge now our clients id they have disks in separate storage profiles.

 

I found some article from Jon Waite https://kiwicloud.ninja/2017/01/detailed-vm-storage-information-in-vcloud-director/ but there  are information how we can collect metrics which are used today. We would like have historical data (from last month) to correctly charge our clients. If this possible by cassandra ? or maybe is some additional solution...

in vCD 9.7 , the only way to add a Provider VDC that is backed by an NSX-T manager, is via the API.

Hi Daniel,

 

It certainly does help, thank you! Sounds like we may have to deploy a LB in front of the cell. I guess it would have to be deployed anyway when we eventually deploy additional cells so no harm done doing it from the start.

Hi there

 

I have a question with regards to vCD 9.5 console access options: VMRC vs web console. What are the pros & cons of each option? There must be some but I failed to find them yet.

Hi Conor,

 

Can you explain what did you change in the permission? I have the same issue, or similar, but cannot find a way the installation finish with success.

 

In the setupvcd.log I have this:

I can write in the folder/mount without any issues, it seems the issue is that cannot change permissions on the folder. If I try to change permission I also get Permission denied.

 

I am stuck here and cannot go further.

 

Thank You

Hi

 

Found the issue. The installation was not able to take ownership of the folder with the vcloud user.

 

It was still own by the root user.

 

So I manually change the ownership to vcloud user and rerun the configure script and all work ok.

 

Thank You

How to achieve Single URL for Multi Site Setup - Tenant Login

https://cloudportalurlA/provider is single portal address, in case of multi-site will have another portal address i.e. https://cloudportalB/provider - this make sense from Admin point of you.

 

If my sites are Active / Active and offered to customers, do I need to give them separate URL to access their Organization within different sites? - Isn't there a central way, considering I might grow few more sites in span of time and giving them multiple URLs to access is not a viable option?

The other option is to change the umask setting on the NFS server. Edit /etc/profile and add the line "umask=000". This will ensure that all new files are global r/w.

I am aware of the federation but this is after onboarding a Tenant on both Sites, whereas what I am looking for is customer to just type a single URL for example:

 

https://centralsite or https://centralsite/tenant/testorg

 

This redirects to site1 or site2 based on validating where the customer resides, or ask a customer which site he wants to access rather then giving customer multiple URLS if he is multi site customer. This will also help in me if I introduce site3 or having maintenance of site 1 etc.

 

Something similar to how Public Cloud works, you login and then navigate to site you are interested in.

Not possible today with vCD. To achieve this, you would need to utilize a northbound solution like a GLSB or utilize WorkspaceONE that federates each vCD instance and passes the SAML handoff to that respective site.

Creating vApp Network in HTML5 Portal throws error VCD 9.7.0

I get the following error in the HTML5 Tenant portal when trying to create an Isolated vApp Network as an Org Administrator.  I am able to successfully create the vApp Network using the flash tenant portal, so I do not believe it is a permissions issue.  I get the same error when trying to create a routed vApp network.   The only network currently added to the vApp is the single OrgNetwork that exists within the DemoCustomer organization VDC.

 

Here are the logs from the vCloud cell, no error is caught:

Some additional info:

 

This only seems to occur if a Direct Org VDC Network is already added to the vApp.  I can create a blank vApp and add a standalone isolated or routed vApp network just fine with the HTML5 Tenant UI.  But once I've added an Org Network to the vApp, I can no longer add vApp networks from the Tenant UI.

 

Has anyone else seen this behavior?   I do have a slightly modified Org Admin role that removes some functionality, so it's possible I have broken something.  But considering this works fine within the Flash portal I believe it's more likely a bug with the HTML5 tenant UI.

We do have GSLB, would like to understand more on how it should be implemented considering each tenant have their own URL and how it will filter between URL etc., also what will happen if one site portal is down for maintenance.

 

If you have any experience over this, would appreciate your share on it.
