This on-demand system performance boost brings the following benefits:
l The system performance is improved gradually, balancing the ROI and the system
service life.
l Components for upgrade are available, following the Moore's Law to reduce the
purchase cost and the TCO.
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. Figure 3-1
depicts the working principle of SmartTier.
