Evgeniy Polyakov, listed as the connector and w1 subsystem maintainer, announced the first release of his distributed storage subsystem, "which allows [you] to form storage on top of remote and local nodes, which in turn can be exported to another storage as a node to form tree-like storages." He describes the features of this new block device: "zero additional allocations in the common fast path not counting network allocations; zero-copy sending if supported by device using sendpage(); ability to use any implemented algorithm (linear algo implemented); pluggable mapping algorithms; failover recovery in case of broken link; ability to suspend remote node for maintenance without breaking dataflow to another nodes (if supported by algorithm and block layer) and without turning down main node; initial autoconfiguration (ability to request remote node size and use that dynamic data during array setup time); non-blocking network data processing; support for any kind of network media (not limited to tcp or inet protocols); no need for any special tools for data processing (like special userspace applications) except for configuration; userspace and kernelspace targets."

In his blog, Evgeniy noted a similarity to the recently discussed DRBD. In the recent announcement he compares his solution to iSCSI and NBD noting the following advantages: "non-blocking processing without busy loops; small, pluggable architecture; failover recovery (reconnect to remote target); autoconfiguration; no additional allocations; very simple; works with different network protocols; and storage can be formed on top of remote nodes and be exported simultaneously".
