Storage Management and Data Services Flashcards

Which Nutanix storage feature automatically moves data between SSD and HDD tiers based on access patterns?

Answer: Intelligent Tiering (ILM)

Nutanix Intelligent Lifecycle Management (ILM) automatically promotes and demotes data between storage tiers based on how frequently it is accessed.

What is the default replication factor (RF) in a Nutanix cluster that protects against a single node failure?

Answer: RF2

RF2 stores two copies of data across different nodes, providing tolerance for a single node or disk failure while balancing storage efficiency.

Which Nutanix data efficiency feature eliminates redundant data blocks across a storage container?

Answer: Deduplication

Deduplication identifies and removes identical data blocks, storing only a single instance and replacing duplicates with pointers to reduce storage consumption.

In Nutanix AOS, what is a Storage Container?

Answer: A logical storage policy grouping that maps to a datastore

A Storage Container is a logical grouping within a storage pool that allows administrators to apply storage policies (compression, deduplication, RF) and presents as a datastore to hypervisors.

Which Nutanix feature reduces storage space by encoding data with parity, tolerating failures with less overhead than full replication?

Answer: Erasure Coding (EC-X)

Erasure Coding (EC-X) stripes data with parity information across nodes, providing fault tolerance at a lower storage overhead than RF2 or RF3 for cold data.

What is the function of the Nutanix Curator service?

Answer: Performs background data integrity scans, compression, and deduplication jobs

Curator is a distributed metadata service that runs background tasks such as disk balancing, erasure coding, compression, deduplication, and integrity checks across the cluster.

When configuring a Nutanix storage container, what does enabling 'Thin Provisioning' mean?

Answer: Storage is consumed only as data is actually written

Thin provisioning allows a container to present more logical capacity than physically available, consuming real storage only as data is written, improving overall utilization.
