What is our primary use case?
My use case was a small FlexPod architecture (seven Cisco B-Series Blades, a FAS8200 in CDOT, two Cisco Nexus switches). One rack. We used Cisco 3xxx switches. Six profiles were defined so six blades were running and one was a spare.
On top of the infrastructure we used Oracle Hypervisor (OVM); the VMs were based on Oracle Linux. On top the virtual machines we hosted Oracle Database (pinned, to reduce license costs) or applications.
So two levels of flexibility per DR were activated: one based on profiles and one based on the hypervisor.
How has it helped my organization?
The customer added the FlexPod-based solution to a real-time system to improve their overall system with a new analytics environment.
What is most valuable?
- Software flexibility. Everything is fully configurable.
- The reliability results from the design. Elements are well projected (disks, blade, network, etc.).
- No single point of failure is identifiable.
What needs improvement?
FlexPod was born to be used like building-block elements, to create large EDP premises. If used to create a single FlexPod CED, optional operational collaterals (backup, management, etc.) are missing, both in docs and in design.
For how long have I used the solution?
One to three years.
