If a certain level of storage performance is required for that data then it will be stored in Tier 2 if that offers the required level of performance, or, if it does not, then it will be stored in the more expensive Tier 1.Ī tiered storage system with three storage tiers is likely to be more efficient, because that same piece of data can be stored in Tier 3 if that offers the required level of performance, or if not then it can be stored in Tier 2 if that offers the required level of performance, and only when both Tier 2 and Tier 3 fail to offer the required level of performance does it need to be stored in the most expensive Tier 1 storage. ![]() How Does Tiered Storage Work?Ī tiered storage system with just two storage tiers offers storage administrators a very limited choice over where a given piece of data should be stored. The objective of a tiered storage system then is to minimize storage costs by using the least costly storage option possible which provides the minimum required performance. So tiered storage is not driven by the needs of the IT department for operational reasons, but purely for financial reasons. Data that is less important can be stored on lower cost, lower performance systems such as hard drives, and data that is rarely accessed, or is only retained for compliance purposes, can be relegated to very low cost offline storage systems That means that SSDs need to be used judiciously, and only for storing data that is used by systems that require very high performance. And unfortunately SSD storage is expensive compared to hard disk drives, and far more expensive than tape storage. If expense were no object, businesses would use SSDs for all their storage requirements because they offer very high performance and reliability.īut in the real world storage costs are very important, as IT departments seek to live within their budgets and organizations as a whole seek to minimize costs and maximize efficiency. Each one is subtly nuanced to produce a different combination of the three key storage attributes: cost, performance, and capacity. ![]() ![]() Tier 0 or Tier 1 is usually made up of flash or 3D XPoint-based solid state drives, while successive tiered storage levels may involve high performance fibre channel or SAS drives (or RAID arrays containing them), lower performance SATA drives, optical disks, tape storage systems, and cloud-based nearline or offline storage systems.Ī 3 tiered storage model using disks and tape to provide tier 1, tier 2 and tier 3 storage was perhaps the most popular tiered storage model before SSDs and cloud storage became commonplace.īut now it is not unusual to use a tiered storage model that involves five or more tiered storage levels. ![]() The different storage media are organized into a hierarchy, where the highest performance storage media is deemed to be Tier 0 or Tier 1, followed by Tier 2, Tier 3, and so on.
