Tier 0/1/2 Disk
AVM Cloud offers 3 different tiers of storage
Tier 0 storages, also known as all flash storages are meant for applications that require high performance, low latency storage such as databases for ERP or e-commerce. This offers reliability and efficiency, providing customers a peace of mind.
Tier 1 storage utilizes spinning disks that are made up of performance disks to provide fast performance with reasonable latency that is optimum for application that do not require millisecond latency from the storage IO.
Tier 2 storage is meant for archiving workloads which are low cost but have higher disk latency.
The recommendation is to have critical applications and databases on tier 0 and non-critical application on tier 1.
