Problem Space, Problem Background
Train Release Update

Train and Beyond
Priorities, Themes

3. Manila is the control plane to provision and
manage shared file systems across storage
systems.
One popular oversimplification: Manila is Cinder
for file shares.
Fork of OpenStack Cinder, built by a shared pool
of developers, shares much of Cinder’s
architecture.
But it solves a new class of problems that Cinder
does not naturally address.
Think: Manila file folders
What is Manila

4. ● Consistent, simple REST API

14. ● Pagination enhancements in the API
● Bug-fixes committed to accommodate deployment of manila-api with uwsgi
● Dell EMC Unity driver can now connect over an IPv6 management interface
● Dell EMC VMAX driver’s been rebranded to PowerMax, if used, the “emc_driver” configuration
option must be set appropriately after upgrade. A few VMAX configuration options have been
renamed as well, this must be reflected to avoid deprecation warnings in the logs.
● Several new configuration options have been added to the Nexenta NS5 storage driver to make
management of NS5 easier.
