As SSD capacity increases, the original limit for provisioning has become obsolete. Based on the pre-installed memory allocation, take the lead to expand the maximum capacity of disk group / pool / volume capacity in thin provisioning.
Take RAID6 as an example. Traditionally, 8 drives are required for parity to achieve 256TB capacity in a disk group. Now two drives are enough. The cost of extra drives could be saved, and the drive utilization gets improved.
SSD Cache
The SSD cache is a large second-level cache that uses enterprise SSDs that sit between the main memory cache and the HDDs. The SSD read/write cache improves the random IOPS of the system's read and write I/O by copying frequently accessed random data to the SSDs which are faster than the HDDs.
Improve Performance, Spend Less
With this technology, SSD cache can improve random read performance by up to 92 times and random write performance by up to 171 times. SSDs also provide a larger, scalable cache than memory. Therefore, it can improve overall performance by using only a few SSDs.
Auto Tiering
Auto tiering cost-effectively and dynamically places hot data on SSDs or faster hard drives and cold data on lower cost high-capacity drives, allowing you to optimize application performance without straining your budget or sacrificing capacity.
Put the Right Data in the Right Place at the Right Time
Auto tiering algorithm uses intelligent data analysis that continuously monitors data usage and ranks this data based on how often it is accessed. It will then use this information and make a decision on where your data should be.
