This Cisco VMDC solution is multi-tenant data center architecture that uses Vblocks defined by VCE coalition. The architecture specifies two PoD ("point of delivery") sizes, large PoDs and compact PoDs, which differ in compute and storage scalability as well as access- and aggregation-layer design to meet the scalability requirements for different sizes of data centers.
The compact PoD includes 64 servers, and the large PoD includes 512 servers. The design for both the compact and the large PoDs provides the capability to incrementally scale resources by adding multiple such PoDs to the system.
The Cisco Virtualized Multi-Tenant Data Center VMDC 2.0 solution eliminates the cost of home grown development of orchestration systems and complexity of designing, integrating and verifying that all systems and tools work together. It integrates crucial components of the cloud, including the virtualized infrastructure building blocks (compute, storage, and network), service orchestration for automation and configuration management, and end-to-end security.
Now question is How do we design Compact PoD using VBlocks as sub components? Which Vblock (0,1 ,2) to be used within which PoD?

It was funny that they did not come up with Vblock 0 until recent 2010, Vblock0 is my favrate for jump starting private cloud.
ReplyDeleteSharing of resources within different business unit is trouble.
pre-tuned, pre-tested, updates , and support as 2 of them belong to one company and cisco will support only network part.

As per my understanding –
ReplyDeleteCisco VBlock architecture consists of Compute, Network (limited to Nexus 1000V), Storage (with EMC Celerra and Nexus 5000) and VMware for virtualization. Whereas PoD talks about end-to-end stack with Network (routing and switching), Security (Layer 4-7 with Firewall and Load Balancers), Storage (high end EMC SAN and Nexus 7K), Compute, VMware and Service Orchestration layer as its components. PoD architecture has also considered different combination of service tiers such as Gold, Silver and Bronze.
For setting up a IaaS we should go with combination of VBlock and PoD components such as Network (routing and switching), Security (Layer 4-7 with Firewall and Load Balancers) and Service Orchestration layers from PoD design and Compute, Network (limited to Nexus 1000V) and Storage (with EMC Celerra and Nexus 5000) from VBlock design and VMware as virtualization component.
Which orchestration layer would be recommended in a PoD design?
