Thick Provisioning
Thick Provisioning is a storage management approach used in virtual environments where all storage space is allocated upfront when creating virtual machines or drives. Think of it like reserving a whole conference room even if you only need half the space - you're guaranteeing that space will be available when needed. This is different from Thin Provisioning, which only uses space as needed. When you see this term in resumes, it usually indicates the candidate has experience with storage management in virtual environments like VMware or cloud platforms. It's a basic but important concept that shows understanding of resource management in virtual environments.
Examples in Resumes

Example Interview Questions
Senior Level Questions
Q: When would you recommend using Thick Provisioning over Thin Provisioning in a production environment?
Expected Answer: A senior candidate should explain that Thick Provisioning is preferred for critical applications needing guaranteed performance, like databases or high-traffic applications, where you can't risk running out of storage space. They should also discuss the trade-offs between storage efficiency and performance guarantees.
Q: How would you plan storage capacity for a large virtualized environment using Thick Provisioning?
Expected Answer: The answer should cover calculating total storage needs upfront, including growth projections, discussing budget considerations, and explaining how to balance resource allocation across different types of workloads.
Mid Level Questions
Q: What are the different types of Thick Provisioning and their use cases?
Expected Answer: Should be able to explain eager zeroed and lazy zeroed thick provisioning in simple terms, and when each type is most appropriate for different business needs.
Q: How do you monitor storage usage in a Thick Provisioned environment?
Expected Answer: Should describe basic monitoring tools and practices for tracking storage usage, capacity planning, and ensuring efficient resource utilization.
Junior Level Questions
Q: What is the difference between Thick and Thin Provisioning?
Expected Answer: Should be able to explain in simple terms that Thick Provisioning allocates all storage space immediately, while Thin Provisioning only uses space as needed.
Q: What are the basic steps to create a Thick Provisioned virtual disk?
Expected Answer: Should demonstrate knowledge of basic procedures in common virtualization platforms for creating virtual disks with Thick Provisioning.
