Dynamic Storage Tiering for Hotspot Data
In media and website applications, information has a high access frequency, which will
generate hotspot data. The hotspot data receives simultaneous read and write requests from a
large number of servers, and poses a demanding requirement on storage system performance.
Traditional storage systems cannot address such a storage requirement.
The OceanStor 2600 V3 storage system uses the intelligent data tiering technology, SmartTier,
to identify hotspot data and promote it to high-performance SAS disks or SSDs. If SmartTier
later finds out that the hotspot data becomes cold (receiving fewer access requests), it demotes
the data to low-performance disks and clears storage space for new hotspot data.
depicts the working principle of SmartTier.

The system performance is improved gradually, balancing the ROI and the system
service life.
Components for upgrade are available, following the Moore's Law to reduce the
purchase cost and the TCO.
