HyperCore Enhanced Automated Tiering
Optimizing Storage Efficiency with HEAT
The addition of flash storage in SC//HyperCore nodes allows more capabilities in the SCRIBE storage architecture with the HyperCore Enhanced Automated Tiering (HEAT) feature.
SC//HyperCore meters real-time IOPS for each virtual disk, so the results of changing the priority on a particular disk can begin to be seen immediately.
HEAT includes configurable flash priority allocation at the individual virtual disk level through an easy-to-use slide bar in the HyperCore UI, and intelligent data block priority based on block I/O heat mapping assessed utilizing historical information on each virtual disk to achieve the correct balance of IOPS efficiency across virtual disks and VMs.
HEAT-capable clusters will automatically assign all new writes to the flash tier until SCRIBE is able to accurately assess their activity. In theory, an SC//HyperCore cluster with low storage utilization could run completely on flash storage.
HyperCore Enhanced Automated Tiering (HEAT) Overview
HEAT Efficiency Scale
By default, a new virtual disk will automatically get assigned a flash priority of 4 on a scale of 0 to 11. The scale, represented by the slide bar in the HyperCore User Interface, is exponential, meaning that changing the priority of a VM virtual disk from 4 to 5 in the HyperCore UI doubles the priority of that data for flash placement.
The graph above shows an example of a VM virtual disk being prioritized from 0 to 11, assuming all other VM virtual disks remain at the default setting of 4.
This scaling means that even one position change on the slide bar can significantly improve performance and requires less experimenting with various settings. The values of 0 and 11 on the slide bar are unique. A setting of 0 eliminates flash storage usage on that virtual disk (convenient for a static FTP drive, for example), and 11 changes the flash priority by order of magnitude, multiplying the priority of the virtual disk data for flash storage placement by 10. When you turn it to 11, you really crank it.
