1. CoprHD and OpenStack
Ideas for future

2. Agenda CoprHD in OpenStack: current approach
CoprHD as SDS Controller for OpenStack
Benefits
Phased approach
Projects

3. CoprHD in OpenStack (current solution)
Advantages
Keystone
Horizon
Swift
Simplified Management (CoprHD side)
Orchestration of complex workflows (with VPLEX, RecoverPoint)
Data Lifecycle Management
High Availability: service, storage
Policy Based Provisioning
Nova
Cinder
Neutron
CoprHD Cinder driver
OpenStack
Issues
CoprHD
Manual configuration (cinder side)
Tenant mapping – CoprHD/OpenStack
Clear-text passwords (in cinder)
Dual layer
EMC
IBM
HDS
NetApp …

4. CoprHD as Storage Controller
Overview
Keystone
Horizon
Swift
Implement block storage API in CoprHD
No changes to other OpenStack components
Nova
CoprHD
Neutron
OpenStack
Advantages
Driver approach advantages, plus:
Simplified Management
Eliminate extra layer (cinder)
1:1 Tenant mapping
Performance
Active/Active HA service
Ingestion
EMC
IBM
HDS
NetApp …

5. CoprHD with Dual API heads
CoprHD REST API clients
Cinder REST API clients
Port 8443
Port 8776
Auth service
API service
CoprHD REST API
Cinder REST API
System service
DB service
Coordinator service
Controller service
Cassandra database
Zookeeper software
Hardware

6. CoprHD with dual API heads
Nginx enables multiple API endpoints
Can register Block storage API endpoint in Keystone
Tenants can be mapped 1:1
Varray can be mapped to availability zone

7. Some use cases Use case Current With CoprHD
Storage Configuration
Manual steps – CLI, edit file, restart service, …
Everything possible via UI (Portal)
FC network zoning
Limited – doesn’t handle split networks
Full capability auto zoning
Storage services
Basic features
Advanced – HA, replication, tiering, discovery, multipath
Volume types
Admin has limited visibility (name only)
Complete visibility to specific features (through virtual pool)
Multi tenancy
Limited
Advanced
Plus: Performance, High Availability, Upgradability, …

8. Deployment options Situation Use Deployment
Dev/Test
Small deployment
No scalability requirement
Using LVM or commodity storage
Use native cinder
Use cinder drivers
Use cinder as block storage controller
Use CoprHD via its cinder driver
Multiple arrays of same type
Simple configuration
Moderate scalability requirements
Use CoprHD as SDS controller
Use native drivers where available
Deploy cinder as a provider for CoprHD
Use cinder drivers where needed
Map tenants 1:1 between OpenStack and CoprHD
Can apply quotas, reservations
Can get metering information
Offers good visibility and automation
Production / Enterprise
Large heterogeneous data center
High scalability requirement
Southbound SDK is critical for deployment

9. CoprHD + OpenStack: Phased approach
Phase I (Enablement)
Cinder driver with multiple arrays in the backend
Phase II (Ease of use and Integration)
API Compatibility for Block, File
Ubuntu, RHEL and other platforms
Distro support
Physically sharing the same node (support for deployment options)
Drivers -- expand the support
Generic but important (not OpenStack specific
Use cases which span block and object – monitoring, backup/archive
Phase III (Leadership)
Improve APIs, contribute features, drive improvements
CoprHD to be part of major Distros

10. SDS Controller for OpenStack: VisionUI
OpenStack Compute (nova)
Other services
Other services
Networking
Identity and authentication
Other services
OpenStack Storage (CoprHD)
Other services
block
file
object

11. Storage for Heterogeneous Private Cloud
Centralized Management of Storage for all Compute Platforms
OpenStack
VMware
Bare Metal
Manila (File)
Cinder
(Block)
vCenter
vCloud/ vCenter
Customer Orchestration
CoprHD

12. API Implementation – current status
Completed
Not started (Curt & Anil)
Volume API v1, v2
Create, delete, expand volume
Attach, detach volume (FC and iSCSI)
Create, delete snapshot
Clone volume
Create volume from snapshot
Keystone v2 interface
Keystone based authentication (tokens)
CLI and Horizon testing
Automated service registration in keystone
Glance interface
Keystone v3 interface – needs more analysis
QoS
Create image from volume
Testing using tempest
Needs exploration (Reddy & Anil)
Volume stats ?
Backup (swift)
Ceilometer
Work In Progress (EMC)
Consistency Group
Create volume from image

13. OpenStack projects for future
Tools needed for developers
Goal: CoprHD should run on Ubuntu & Centos (only instructions)
Docker
Co-existence (on same hardware?) with OpenStack services
User deployment
Currently only SLES OS, no upgrade, no multi-node
Add Ubuntu and Centos
Add multi-node (instructions)
Co-existence (on same hardware?) with OpenStack services, don’t reboot node
Keystone to be the only auth provider – remove proprietary token management (does this make sense for non-OpenStack environments?)
CI tools integration – Jenkins to include tempest tests
OpenStack CI setup with CoprHD
