What is tiered storage architecture?

What is tiered storage architecture?

A tiered storage architecture categorizes data hierarchically based on its business value, with data ranked by how often it’s accessed by users and applications. The data is then assigned to specific storage tiers that are defined by their performance, availability and media costs.

What is tiered memory?

Tiered memory is a generalizable memory architecture that leverages the heterogeneous power-performance characteristics of each tier. For instance, there is a large body of recent work on hybrid memory systems that mix multiple memory technologies (e.g., DRAM and PCM) [ 4], [ 8].

What is the tiered storage spaces feature and how does it work?

Tiered storage allows companies to store each class of data based on the minimum performance that it requires and the lowest cost storage that can handle those requirements.

What is tiering of data?

Data tiering is the process whereby data is shifted from one storage tier to another as its state changes dynamically from hot to cold and vice versa.

What is auto tiering in a storage array?

Auto-tiering is a quality of storage service feature that enables logical volumes or LUNs to span different tiers of storage and transparently move portions of the logical volume between tiers of storage to minimize storage costs and deliver consistent performance and throughput.

What is tiering policy in NetApp?

A tiering policy determines when or whether the user data blocks of a volume are moved to the cloud. You can also adjust the cooling period. This is the number of days that user data in a volume must remain inactive before it is considered “cold” and moved to object storage.

What is tiering in cloud computing?

Cloud services are usually divided into three basic levels, or tiers, that are differentiated by the level of abstraction they present to consumers. The lowest tier is infrastructure-as-a-service (IaaS).
