A client business IO load random read that accounts for more than 60% using SATA, SAS for staging storage, use SSD to do cache, so it will effectively reduce costs and improve random performance indicators

If hot spot data is scattered and changing rapidly, it is recommended to use tiered storage

If there are many SSDs and hotspots, Smart Cache is the best choice

If you have a small amount ofSSD data, use a tiered storage disk for more utilization

According to the different retention time to divide the media pool

As many media pools as possible to improve performance and utilization

According to the purpose of the disk to partition the media pool

According to the number of storage strategies or use to divide
