Methods of SMR Data Management

引用:

Host Managed

The next type of management is known as host managed. With this type of management the host uses commands and Zone information to optimize the behavior of the SMR drive by managing IOs to ensure writes are always sequential within a Zone. If a host sends a non-sequential write within a Zone the drive will reject it and return an error. This gives the drive more predictable performance and would be more likely to be seen initially in enterprise and hyperscale applications.

The down side to host managed is that the SMR drives are not compatible with host systems (HBAs, device drivers, filesystems, databases, etc) that are not SMR aware. That means file systems need to be adapted to support SMR drives. This is occurring, first in the hyperscale space where the largest players in the world have the ability to modify their storage stacks to account for SMR, and now also in the mainstream open source space. The xfs maintainer, Dave Chinner, published a document outlining the SMR optimizations for xfs during the Linux Vault conference in Boston in early March. In the same event, Hannes Rienecke of Suse presented a Zone caching mechanisms that can allow current filesystems to work with host managed SMR drives. It’s likely that these investments together with an appetite for capacity will encourage others to adopt the new open source solutions and pursue modifications to their systems to support SMR drives.

Host-managed SMR........

給你硬碟的人該不會就是被這樣拐到的吧........是在哪買的........
這種特殊品商家都沒提醒一下嗎?.........

靠，這種硬碟是要靠哪種controller才能正常使用?
10TB以上的以後變得比磁帶還難搞?太瞎了
