Tintri Multi-Tenancy for Cloud Computing

BACKGROUND

Cloud computing offers on-demand availability of computer system resources, especially data storage and computing power, delivering hosted services over the internet. In data storage, Multi-tenancy in cloud computing makes a greater pool of resources available to a larger group of people without sacrificing privacy & security or slowing down applications. Multi-tenant environment allows a group of people all share access to the hardware memory through the underlying software. For instance, a service provider may offer a hosted private cloud service to its customers in which each tenant has administrative access to its own instance of vCenter and a set of dedicated ESXi hosts, but underlying storage resources are shared. For large enterprise companies, IT organizations may create an enterprise cloud in which they can dedicate resources to meet the IT needs of internal “tenants” such as development teams or line-of-business teams.

GOAL

Streamline user experience to allow Service Providers to monitoring all space usage and have full control over how much total space a tenant can consume and make it simple to limit capacity available to each tenant in the multi-tenant environments.

PROBLEMS

No full control over storage capacity limit

Service Provider would like to charge end customers for the space they used but they didn’t have full control to manage their customers quotas and capacity.

No warnings prior storage over capacity

Service Providers didn’t receive warnings until their customers reach quota limit, which could be a dangerous situation since VMs can crash when writes start to fall. 

SOLUTIONS

1. Allow storage engineers to create Service Group & set quota policy

Service Groups aggregate VMs that have common management needs. A multi-tenant environment is created through a combination of VMware vCenter configuration and service groups. A Service Group is used to group all of a tenant’s VMs, allowing common management of the associated storage. Part of that management includes the ability to specify a quota is to set up a multi-tenant environment, users need to create a Service Group for each tenant and assign each Service Group a hard quota. When they create a Service Group with a quota, a sub-mount is created automatically. A vCenter datastore can map to an entire Tintri array, or it can map to a sub-mount on an array, with or without a quota. Service Group creation is performed using Tintri Global Center (TGC). When users select the Service Groups tab and click on “add a Service Group,” they just need to provide a name and description for the group to create a Service Group with a quota:

2. Provided ability to modify storage usage quota

After creating a Service Group to monitoring space usage, users may modify quotas for the Service Group that they created along with data protection replication and QoS, if desired. When they select Edit in the Quotas section, they can then assign a quota in GiB, along with various alert thresholds.

3. Allow storage engineers to monitor space usage trend

Users can view physical space and logical space usages of a specific Service Group from the list view or from a specific Service Group detail metrics view by selecting the Service Group Metrics tab, they can see logical space vs. physical space usage along with a variety of other graphs related to usage.
