Prism Central offers first class security for your customers with VMware Horizon DaaS

Prism Central is a powerful management tool that allows administrators to centrally manage and control Nutanix clusters around the world from a single pane of glass. It removes the operational complexity from managing multiple clusters in a single location, or when geographically distributed across different datacenters. Combined with VMware Horizon DaaS both the service provider and customer\tenants get flexibility without sacrificing security.

The platform-agnostic HTML5-based interface provides a bird’s-eye view of IT resources across multiple clusters, enabling administrators to select and manage individual clusters as required. Single sign-on streamlines large-scale management by eliminating the need to log into each cluster individually. Prism Central also gives administrators an aggregate view of all resources in the environment to quickly and efficiently monitor all VMs and storage resources and identify potential issues in individual clusters. It can be deployed in any one of the Nutanix clusters in the global environment.

Prism Central enables service providers to offer physical, isolated environments for all of their tenants without the worry of increased management costs. Tenants can be given read-only access to their clusters and additional time managing reservations can be avoided as the failure domain is isolated to the tenant. Tenants needing the newest features can move quickly to new releases without impacting the rest of the environment. Today over 100 clusters can be managed with Prism Central.

Prism Centeral

This is the only hyper-converged platform that allows this type of management without imposing restrictions on the vSphere cluster design. Some customers may want their own vCenter(s), some may want to split compute clusters for different departments and some may never even want to see vCenter.

Cleaning up stuck tasks on VMware Horizon Air (Desktone)

I had already tweeted a link to the support KB -> Unable to Delete the Pool at This Time (2100079) but the commands for logging into the database don’t require the options ie “-U”. Below are the commands I used.

Also you can only connect to the database by going from Service Center via ssh -> Tenant Management appliances on the backbone network.

desktone@tenantApp1:~$ psql edb admin
Password for user admin:
psql (9.0.13)
Type “help” for help.

edb=# delete from t_task ;
DELETE 4764
edb-# \q

desktone@tenantApp1:~$ psql fdb admin
Password for user admin:
psql (9.0.13)
Type “help” for help.

fdb=# delete from poolmgr_tasks;
DELETE 1221
fdb=# delete from poolmgr_task_params;
DELETE 0

Horizon DaaS\Air Advanced Settings Gone Wild

Working with Horizon Air has had some challenges do to lack of Google finding my answers and VMware KB’s having three separate products listed but I do think VMware has the interests of the Service Provider in mind. Since I love nothing more that shooting myself in the foot I went off to change some of the advanced settings. This is harder than it looks because you have to use the “secret” handshake to get at them.

On the policy page for your tenant you need to type dtpolicy anywhere on the page. If you see Do not change policy settings without consulting VMware support, you’re headed in the right direction.

Nutanix Horizon Air

The following VMware KB article talks about the same thing. – I do not see the policy I am searching for http://kb.vmware.com/selfservice/microsites/search.do?cmd=displayKC&docType=kc&externalId=2100146&sliceId=1&docTypeI
