Managing VSD storage for multiple system disk support
The following topics provide information and instructions for managing virtual system disk (VSD) storage for multiple system disk support:
- Adding additional system disks to a service blueprint
- Adding additional system disks during provisioning
- Adding additional system disks after deployment
A VSD represents storage that is connected to a virtual machine (VM) via a hypervisor datastore such as a VMware virtual machine file system (VMFS) data store. A VSD is treated as a compute resource by BMC Cloud Lifecycle Management. In a service blueprint you can define multiple VSDs for each server.
By specifying system disks in service blueprints, you can:
- Support more service offering combinations with fewer service blueprints for VMs
- Reduce storage and management costs
- Respond to changing business needs with greater flexibility
For example, you might create a blueprint for a service offering that requires multiple tiers of storage such as a traditional physical disk drive for the OS and a solid-state drive (SSD) for the database tables. Or, you might create a blueprint for a Red Hat Linux service offering that enables a user to request one or more disks.
You can add additional storage resources to a VM in the following ways:
- By specifying additional storage in a service blueprint. You can specify additional storage in a service blueprint on Day 1. For more information, see Adding additional system disks to a service blueprint.
- By creating a deployment requestable offering (DRO) that adds additional storage during provisioning of a service offering instance. You can create DROs on Day 1. For more information, see Adding additional system disks during provisioning.
- By creating a transaction requestable offering (TRO) post-deployment custom action that adds additional storage to a deployed service offering instance. You can create TROs on Day 2. For more information, see Adding additional system disks after deployment.
