The Efficient Use of Storage Resources in SAN for Storage Tiering and Caching

Abstract

With the rapid growth of the Hyper Convergence (HC) the use of the Solid State Device (SSDs) as the intelligent Storage Tiering and caching has increased immensely. It plays an important role to provide high throughput and performance with maximum utilization of the SSD storage space considering the life cycle of SSDs and workload. Efficient Utilization of such resources is one of the main criterion of the virtualization technology. By considering the rise of the VDI workload the proposed implementation of a sequential write detection algorithm, we try to maximize the utilization of higher tier storage such as SSDs (Tier 0) by placing the data which fall under the category of sequential writes into the lower tier disks (Tier 1, 2 - n) such as SAS (serial attached SCSI) / SATA (serial advanced technology attachment).
