Abstract
Techniques are described in which network devices, such as one or more data center access nodes, are configured to support durable block storage with inline erasure coding, i.e., erasure coding in real time as data is updated. A Durable Block Device (DBD) supports a block level API for one or more storage volumes that may be mapped to one or more applications executed by servers in communication with the data center access nodes. The disclosure describes the operation of the data plane of the DBD that is hosted on one or more access nodes, and its interactions with the management and control planes of the DBD that are hosted on one or more of the servers. The disclosure describes generation of a log structured volume in the DBD configured to gather multiple data blocks into larger chunks of data for inline erasure coding for storage across multiple storage devices.
