Share of Deployments of OpenStack in Production
to
Production-grade Deployments of Manila Shares

OpenStack Foundation October 2016 Survey
Share of deployments in production is 20% greater than a year ago

Strong OpenStack Deployment in Production and Pilots
Red Hat has over 350+ private
cloud customers and ~40 POCs
underway at any given time,
which aligns with this data.
Over 40% are in production and/or are undergoing a proof of concept with OpenStack,
while 20% are preparing to deploy OpenStack

OpenStack Used for Variety of Legacy & New Workloads
OpenStack is not
used only for net-new,
cloud-native
workloads but for a
variety of existing and
new workloads
Over 60% are using OpenStack for existing virtualized workloads as well as new cloud-
optimized workloads

Shared File System Drivers in Use (April 2016 )

The Age of Cloud Share Services
File Share Service Market Trends
●  OpenStack Manila: June 2013
●  Microsoft Azure Files: May 2014
●  Amazon Web Services Elastic File Services: April 2015

Meet OpenStack Shared File System Service
Multi-tenant, secure file share as a service
●  An Open, Standard API for File
System Provisioning and
Management that is designed to
provide a multi-tenant, secure file
share as a service across
OpenStack Compute instances.
●  Vendor neutral API for provisioning
and attaching filesystem-based
storage such as NFS, CIFS,
CephFS, HDFS and other network
filesystems.

Manila Use Cases
●  Support traditional enterprise applications
●  Provide Elastic and Scale file shares
●  Support “cloud-native” workloads, such DBaaS
●  Big Data – via Manila’s HDFS native driver plugin
●  DevOps / On-Demand development and build environments
●  Integration with existing automation frameworks through REST
API or CLI
●  Hybrid Cloud shares (external consumption of shares / migration
of workloads to the cloud from on-premise file shares)
●  NFV/Telco - use case example: store emails headers and bodies
in Manila shares and the the attachment in object storage.
●  Persistent Shared storage for Containers

Use Case I
Move traditional workloads without rewriting them
●  Manila service makes it easier to
transition traditional virtualized enterprise
applications workloads into the cloud
infrastructure without requiring to rewrite
the applications stack, while gaining
lower cost and more heterogeneous
infrastructure.
●  Key requirement:
○ Shared resources
○ High Availability
○ Disaster Recovery

Use Case II
Storage as a Service (Private or Public Cloud)
●  Extend your Storage as a Services
with your own shared file systems
(Similar to AWS EFS)
●  Manila delivers a durable, high-
throughput file system for content-
management systems that store and
serve information for a range of
applications, such as websites, online
publications, email attachments and
archives.

Use Case III
DevOps
●  Challenge:
Speed up Dev and Test refresh
●  Solution:
Run test in parallel by leveraging
containers and cloned Manila shares.
●  Automate database deployment by
leveraging both custom and Trove-based
services.
●  Infrastructure self-service

Production-grade Deployments of Manila Shares

Manila in Red Hat OpenStack Platform 10
●  Production-grade
automated
deployment of
Manila service with
OSP director with
High Availability
●  Horizon dashboard
support (via Manila
UI plugin)

Integration with NetApp Manila Driver
●  With OSP 10 release, the director can now deploy the Shared File System with a
NetApp on the overcloud.
●  NetApp unified driver Certified backend
●  Allows the Shared File System service to use NetApp storage controllers
(running Data ONTAP) as a back end.

Integration with NetApp Manila Driver
In addition to all the standard features all Manila drivers support, the NetApp
driver supports:
●  Expand/shrink shares (All drivers can expand but shrink is optional)
●  Manage/unmanage shares (for importing and exporting data to/from Manila)
●  Snapshot and clone from snapshot are both supported and space/time
efficient
●  Share replication (to address DR use cases)
●  Share servers (in addition to no-share-servers) for extra tenant isolation

The road to Ocata

Manila Today -
●  Number of Drivers: 23
●  Blueprints Completed: 14
●  Specs* new with Newton:
○  13 specs proposed
○  5 accepted
■  Share Migration Improvements
■  Store auth secrets in access map
■  Share networks span subnets
■  Share revert-to-snapshot
■  Hierarchical Port Binding
* https://review.openstack.org/#/q/project:openstack/manila-specs

New in Newton
●  Snapshot instance admin APIs
●  Extend share and extend snapshot APIs enhancements
●  Scheduler improvements for thin provisioning, driver filter and
Goodness weigher
●  Access list api enhanced to return access key
●  Network gateway & MTU DB support; port-binding support
●  Many share migration and data service fixes and improvements*
●  Share replication improvements*
* Experimental Features
http://docs.openstack.org/releasenotes/manila/newton.html

Some Production Considerations...
Don’t use Reference Implementation drivers in production!
●  Generic driver is unstable and not cut for scale
Core vs. Experimental and Microversioned APIs
Experimental Features:
●  Consistency Groups
●  Consistency Group Snapshots
●  Share Migration and Data Services
●  Share Replication
Experimental APIs may be changed at will, even removed.
Microversions allow new implementations to break backwards
compatibility while maintaining support for earlier versions of the APIs.

Newton share driver work
New drivers: Docker, Tegile IntelliFlash, Hitachi HSP,
NexentaStor
●  NetApp cDOT driver hybrid aggregate support
●  NetApp cDOT driver snapshot manage/unmanage support
●  CephFS Native Driver (Read-only share support)
●  CephFS Native Driver returns access key
●  Huawei added share replication support
●  EMC Unity driver added NFS/CIFS plugin
●  Hitachi HNAS CIFS support
●  GlusterFS new volume XML schema support
●  GPFS driver NFS Ganesha support
●  ZFSonLinux manage-snapshot support
●  Oracle ZFSSA driver supports manage/unmanage shares
●  Various fixes and enhancements to HPE 3PAR, Hitachi HSP, Huawei, Native
CephFS, NetApp cDOT, ZFSonLinux, and Windows drivers.

Supporting work for Manila in other projects
●  TripleO heat templates and puppet manifests using new
composable/custom roles infrastructure to support overcloud deployment with
NetApp and native CephFS backends.
●  Ganesha work on dynamic update of exports via d-bus
○  Lack of this capability was holding up use of Ganesha by Docker driver
○  Glusterfs and GPFS drivers use today
○  CephFS driver will use Ganesha for NFS gateway
●  Tempest library stable interfaces to improve CI stability
●  Security Vulnerability Management (when CVE’s hit), Barbican example
●  Monitoring, Troubleshooting and Telemetry
●  Kolla have added the support for deploying Manila (for running Manila
services containerized)
●  Fuxi – Docker Manila use for shared persistent volume

New High Availability architecture
Pacemaker systemd
HAProxy / VIPs A/A OpenStack Services
RabbitMQ Memcached
Galera manila-api
manila-share manila-scheduler
Redis
•  Default for new deployments, upgrades to OSP 10 and higher
•  Fencing enabled for Pacemaker managed services when/where required
(testing to determine this)
TripleO Manila Service HA Architecture

Ocata focus and beyond
●  New spec process has been proposed to provide more focus
○  Have fewer features in flight, more finished
●  Begin journey to scalable, active-active services
○  consistent model for avoiding races
○  How to scale out services across multiple nodes while still avoiding races
○  Exploit composable role TripleO infra
●  High Availability & Disaster Recovery
○  Replication, Backup, Snapshots
○  Common understanding of AZs and failure domains for services, resources,
networks, ...
●  Migration, Data Service, Storage/Network protocol independence
○  Single node, scale-out services
○  Continue to refine AZs in manila
■  What are are the relevant failure domains?
■  How to map these to independent services, networks, resources?
