4. Mission Statement
"To produce the ubiquitous Open Source cloud computing platform
that will meet the needs of public and private cloud providers
regardless of size, by being simple to implement and massively
scalable."

5. OpenStack: Open Source Cloud OS
 Public clouds – level the playing field
against “the big three”
– Major Opportunists: Rackspace, HP
– And many more…
 Private clouds – open the door to
many distributors

 Disaggregation at host level

Roll-your-own storage nodes with services
based on a DFS or LVM
All storage and data services on storage

This is SDDC goal for many apps
 Disaggregation at array level

Not as flexible/ubiquitous as disaggregation
at host level
But: proven, performant, and inherently
resilient
Storage arrays have been disaggregating
disks for years
Array-based storage & data services
This is topic for today

 Across Variety Of CloudOS Platforms
 Variety of Solutions Within Each CloudOS Platform
 Continuously Evolve Solutions To Support Customer

20. EMC Best Practices
 Run EMC Volume Drivers Anywhere
–
–
–
–
–
Each Driver Is An Independent ‘cinder-volume’ Service
Low CPU/IO Requirements
Run On Controller Node For Active/Passive HA
However: Future Backup Considerations Will Change This
Scale Practice: Run “storage controller nodes” as VMs
 Best Practices For Access Protocols:
– iSCSI For VNX
– NFS For Isilon (Havana)
– FC For VMAX
 Best Practice White Papers Are Work In Progress
