Zoned Storage Devices (SMR HDDs and ZNS SSDs) have demonstrated that they can
improve storage capacity, throughput, and latency over conventional storage
devices for many workloads. Zoned storage technology is deployed at scale in
some of the largest data centers in the world. There's already a
well-established set of storage vendors with increasing device availability and
a mature software foundation for interacting with zoned storage devices is
available. Zoned storage software support is evolving and their is room for
increased file-system support and additional userspace applications.
The Zoned Storage microconference focuses on evolving the Linux zoned
storage ecosystem by improving kernel support, file systems, and applications.
In addition, the forum allows us to open the discussion to incorporate and grow
the zoned storage community making sure to meet everyone's needs and
expectations. Finally, it is an excellent opportunity for anyone interested in
zoned storage devices to meet and discuss how we can move the ecosystem forward
together.
Suggested topics:
- Ecosystem & Architectural review
- Your journey using or enabling zoned storage devices
- Current and future kernel work (non-power of 2 zones, swap
support, raid, log-structured block devices …)
- Qemu support now and later
- SPDK support now and later
- File systems support now and later (f2fs, btrfs, zonefs, ...)
- Application support now and later (CacheLib, Cassandra, Ceph,
HDFS, RocksDB, MySQL, TerarkDB, your favorite application, …)
- Tools and libraries related to zoned storage devices (blkzone,
fio, libzbd, nvme-cli, xnvme, xztl, …)
- Debugging tools and approaches
If you are interested in participating in this microconference and have
topics to propose, please use the LPC CFP process [1], and select "Zone
Storage MC" for the "Track".
The submission deadline is June 30.
Come and join us in the discussion. We hope to see you there!
