Dynamic Hybrid-SMR: an OCP proposal to enhance information middle disk drives

Early final yr, we revealed a whitepaper on the necessity for brand spanking new disks in information facilities, and introduced we had been becoming a member of the Open Compute Project (OCP) to assist drive innovation in IT infrastructure. Since then, we’ve been collaborating with members of the OCP storage undertaking to align on a set of widespread Cloud Hard Disk Drive (HDD) options and interfaces to adapt to exponentially rising storage wants in information facilities.

Today, we’re asserting that we’re sharing a proposal with OCP for Dynamic Hybrid Shingled Magnetic Recording (HSMR) HDD Product Requirements. Our aim is to work with main cloud HDD distributors, clients and companions to collaborate on defining such an HDD conduct and interface.

As we defined intimately within the Disks for Data Center whitepaper, an everyday Shingled Magnetic Recording (SMR) HDD allows bodily information compression by way of recording format optimizations that decrease the price per byte of an HDD by as much as 10-20 p.c. While such a value discount for cloud storage is extremely wanted, the complexity of a distributed file system managing information placement onto separate SMR and CMR drives, whereas eliminating IOP stranding, is critical. An HSMR HDD, then again, permits IOPs to be shared throughout SMR and CMR information, lowering the probability of stranding.

We consider Hybrid-SMR is the following main milestone in our ongoing pursuit to decrease the price of storage in information facilities. We look ahead to continued collaboration with adopters and contributors as we draft and innovate on this new HDD expertise collectively by way of OCP.  To study extra, and take part within the dialogue, be a part of us on the OCP storage undertaking conferences.
