Storage Tiers

Traditional Storage Tiers

Tiered storage is a data management strategy that involves classifying and storing data in different tiers or levels based on specific attributes, such as data value, access frequency, performance requirements, and cost considerations.  By implementing storage tiering, your organization can optimize its data storage infrastructure, enhance data accessibility, improve performance, and reduce costs.  


Here is an explanation of the storage tiers commonly used in tiered storage.  The choice of storage tiers depends on factors such as data value, access patterns, performance requirements, compliance obligations, and budget constraints.

Tier 0

Tier 0 is the highest-performance storage tier designed for extremely critical and time-sensitive data.  It typically consists of storage media like high-speed solid-state drives [SSDs], non-volatile memory express [NVMe] drives, or in-memory systems.  Tier 0 is ideal for workloads that demand ultra-low latency and require real-time access to data.  It is commonly used for high-performance computing, financial trading systems, and transactional databases where every microsecond counts.

Tier 1
Also known as the primary storage tier, Tier 1 is designed for mission-critical data that requires fast and frequent access.  It includes high-performance storage systems such as all-flash arrays [AFA] or hybrid storage arrays combining SSDs and traditional hard disk drives [HDDs].  Tier 1 storage is characterized by its low latency and high input/output operations per second [IOPS].  It is suitable for databases, virtualized environments, and applications that require high-performance storage for immediate data retrieval.

Tier 2
Tier 2 storage is used for less critical data that is accessed less frequently than Tier 1.  It strikes a balance between performance and cost-effectiveness by incorporating traditional HDDs or network-attached storage [NAS] systems.  Tier 2 storage is commonly used for backups, file shares, and secondary copies of data that may require occasional access or near-line retrieval.

Tier 3
Tier 3 storage is focused on long-term data retention and archival purposes.  It offers high capacity and lower cost per unit of storage but with slower access times compared to higher tiers.  Tape drives and tape libraries are often used in Tier 3 storage due to their high capacity, cost-effectiveness, and suitability for data that is infrequently accessed but needs to be retained for compliance, regulatory, or historical purposes.  Tier 3 storage is commonly used for data archiving, regulatory compliance, and large-scale backup and recovery solutions.

Cloud Storage Tier
Cloud storage has gained popularity as a flexible and scalable option for tiered storage.  Cloud service providers [CSPs] offer different storage classes or tiers, each optimized for specific use cases.  These storage classes may include hot storage for frequently accessed data, cool storage for infrequently accessed data with lower retrieval costs, and cold storage for rarely accessed data with the lowest cost but longer retrieval times.  Cloud storage tiers provide your organization with the ability to scale storage resources dynamically and align costs with actual data usage.

Object Storage Tier
Object storage is a scalable and highly available storage architecture that organizes data as objects with unique identifiers and metadata.  It offers high durability, scalability, and simplified data management.  Object storage tiers can be configured based on access frequency, data lifecycle policies, and cost considerations.  This allows your organization to optimize storage costs by moving data to the most appropriate tier based on its access patterns and value.  Object storage is commonly used for storing Unstructured Data, such as files, images, videos, logs, and backups, in a cost-effective and scalable manner.

Cold Storage Tier
Cold storage is dedicated to storing data that is rarely accessed but needs to be retained for long periods.  It prioritizes cost savings over immediate accessibility.  Cold storage solutions include options such as offline storage media [e.g., tape drives], low-cost cloud storage, or dedicated archival systems.  While the retrieval times for cold storage may be longer compared to other tiers, it offers significant cost advantages for long-term data retention, compliance, and regulatory requirements.
