Qtier
Qtier is a proprietary automated-tiering technology, designed to increase NAS storage performance and
reduce the total cost of NAS ownership.
With Qtier, a storage pool can contain a mixture of solid-state drives (SSDs), hard disk drives (HDDs), and
Serial Attached SCSI (SAS) drives. QTS creates a separate storage tier for each disk type, and then moves
data between the tiers based on access frequency. Frequently accessed data is moved to the fastest disks
for greater read and write performance. Infrequently accessed data is moved to the slower high-capacity
disks for more cost effective data storage.
