We are excited to announce the public preview support to force detach ZRS data disks from a VM residing on a zone impacted by failure. Customers will now be able to detach the ZRS data disks and attach them to another VM, decreasing the RTO.
Zone-redundant storage (ZRS) synchronously replicates your Azure managed disk across three Azure availability zones within the region providing 99.9999999999% (12 9’‘s) of durability over a given year. Zone redundant storage (ZRS) option for Azure managed disks is supported on Premium SSDs and Standard SSDs.
