Quick Poll:
●  How many of you contribute to OpenStack?
●  How many of you are end-users of OpenStack?
●  How many of you are OpenStack Operators?
●  How many of you work for Vendor Organizations that contribute to OpenStack?
●  How many are “all of the above”?
●  How many just heard there was free Beer and Food?

Office:443.433.0106
What do you mean when you say Storage?

Office:443.433.0106
●  Ephemeral
●  Non-Persistent
●  Life Cycle coincides with an Instance
●  Usually local FS/QCOW file
●  Object
●  Manages data as.. well, an Object
●  Think photos, mp4’s etc
●  Typically “cheap and deep”
●  Commonly SWIFT
●  Shared FS
●  We all know and love NFS
●  Soon to be Manila
Number of different types of Storage in OpenStack, each serving a different use case
●  Block
●  Foundation for the other types
●  Think raw disk
●  Typically higher performance
●  Cinder

Office:443.433.0106
Most common question, difference between
Object and Block?
Cinder / Block Storage Swift / Object Storage
Objectives
●  Storage for running VM disk
volumes on a host
●  Ideal for performance sensitive apps
●  Enables Amazon EBS-like service
●  Ideal for cost effective, scale-out storage
●  Fully distributed, API-accessible
●  Well suited for backup, archiving, data retention
●  Enables Dropbox-like service
Use Cases
●  Production Applications
●  Traditional IT Systems
●  Database Driven Apps
●  Messaging / Collaboration
●  Dev / Test Systems
●  VM Templates
●  ISO Images
●  Disk Volume Snapshots
●  Backup / Archive
●  Image / Video Repository
Workloads
●  High Change Content
●  Smaller, Random R/W
●  Higher / “Bursty” IO
●  Typically More Static Content
●  Larger, Sequential R/W
●  Lower IOPS

Office:443.433.0106
Let’s talk Cinder!

Office:443.433.0106
Cinder Mission Statement
To implement services and libraries to provide on demand, self-service
access to Block Storage resources. Provide Software Defined Block
Storage via abstraction and automation on top of various traditional
backend block storage devices.
Huh?
So it’s simply allowing you to dynamically create/attach/detach disks to your
Nova Instances. Those are the basics, much more advanced capabilities
will depend on the version of OpenStack/Cinder and storage vendors’
exposed advanced features.

Office:443.433.0106

Office:443.433.0106
How it works
●  Plugin architecture, use your own vendors
backend(s) or use the default
●  Backend devices invisible to end-user
●  Consistent API regardless of backend
●  Filter Scheduler let’s you get fancy
●  expose differentiating features via custom
volume-types and extra-specs

Office:443.433.0106
Cinder Default/Reference Implementation Includes
●  Base implementation using LVM
●  Just add disks
●  Great for POC and getting started
●  Sometimes good enough
●  Might be lacking for your performance, H/A and Scaling needs (it all depends)
●  Can Scale by adding Nodes
●  Cinder-Volume Node utilizes it’s local disks (allocate by creating an LVM VG)
●  Cinder Volumes are LVM Logical Volumes, with an iSCSI target created for each
➔  Typical max size recommendations per VG/Cinder-Volume backend ~ 5 TB
➔  No Redundancy (yet)

Plugin Architecture gives you choices (maybe too many) and you can mix them together:

Adding Cinder conf file entries
#Append
to
/etc/cinder.conf

enabled_backends=lvm,solidfire

[lvm]

volume_group=cinder_volumes

volume_driver=cinder.volume.drivers.lvm.LVMISCSIDriver

volume_backend_name=LVM_iSCSI

[solidfire]

volume_driver=cinder.volume.drivers.solidfire.SolidFire

san_ip=192.168.138.180

san_login=admin

san_password=solidfire

volume_backend_name=SolidFire

Then restart Cinder service

With Juno release of OpenStack!!!
●  November 2014 is the fifth release of Cinder!!!!
●  Major emphasis on testing and compatibility
●  Running Third Party Continuous Integration’s (CI’s) on Vendors gear in their own labs
against each Cinder commit
●  Manage/Unmanage (or Import/Export) of Volumes widely available
★  Introduced support for Pools for those devices that still have that concept
★  Introduced support for Replication
★  Introduced support for Consistency Groups
★  Continued improvements to Cinder-Backup making way towards incrementals

Office:443.433.0106
New Cinder capabilities in Kilo
★  6th release of Cinder
★  It’s all about QUALITY
★  Running 3rd party Continuous Integration’s (CI’s) on Vendor gear
★  De-emphasizing new features (i.e. finish the ones we have and make them rock solid)
★  Redundancy for base LVM implementation (didn’t make it)
★  Private Volume types
★  iSCSI helper choices for LVM
★  iSCSI Multi-attach – still needs support in Nova.
★  Incremental Backups
★  Rolling Upgrades!!

Office:443.433.0106
Plans for Liberty version of Cinder
Some Highlights:
★  Multi-pathing
★  Image caching (SolidFire’s implementation in Kilo to be generalized in Liberty)
★  Backup Improvements (faster & more flexible)
★  Improvements for Replication

Office:443.433.0106
Thoughts for those building OpenStack Clouds

Office:443.433.0106
Making choices
can be the
HARDEST part!
●  Each has their own merits
●  Some excel at specific use cases
●  Maybe you already own the gear
●  TCO, TCO, TCO
Ask yourself:
➔  Does it scale? How muchstorage functionality exposed via Cinder?
➔  Is the architecture a good fit?
➔  Is it tested, will it really work in OpenStack?
➔  Support?
➔  What about performance and noisy neighbors?
➔  Third party CI testing?
➔  Active in the OpenStack Community?
➔  DIY, Services, both/neither (SolidFire AI, Fuel, JuJu, Nebula….)

●  Including complete software/hardware upgrades
●  Automation top priority in API design
●  Built to deploy in an OpenStack environment
●  Extreme fault tolerance with automatic self-healing

Office:443.433.0106
SolidFire &
Cinder
