OpenStack and NSX integration

Image
OpenStack is basically an open source CLOUD stack, and it delivers the possibility to consume the platform resources using the REST API calls. The "plug-in" architecture of OpenStack services enables various vendors (such as VMware) to integrate their infrastructure solutions (such as vSphere and NSX) to deliver an OpenStack cloud.
In the NSX Architecture diagram the OpenStack represents the Cloud Management Layer that provides governance, resource planning, financial planning etc and potentially manages multiple underlying cloud fabrics. This is all done to provide the transparent flow of the Applications running on top of the Cloud architecture. It´s really important to clear up one thing first: Non-Cloud Environment: An application “owner” would contact one or more datacenter administrators, who would then deploy the application on the application owner's behalf using software infrastructure tools (e.g., VMware vSphere) to deploy the application workloads on top of phys…

Cisco Data Center: Fiber Channel and Cisco Storage Fundations

Unified Fabricis a term for all of the equipment that makes LAN and SAN possible. There are two different networks (LAN as Front-end and SAN as Back-end) that we are trying to “converge”, and 10G is an enabler of that convergence. SAN (Storage Area Network) has 3 high level components: -Storage Arrays, where the Physical Disks are located. These can be JBOD (Just a Bunch of Disks) or RAID. -SAN Switches, that connect the Servers (Initiators) to Storage (Target) can do protocol conversions between FC and iSCSI, FC and FCoE, FC and FCIP. -HBA (Host Bus Adapters) – which is a NIC card for SAN. There are 3 types of HBA: oFibre Channel HBAs (SAN traffic only, 1/2/4/8/16 Gbps). oiSCSI HBA (1/10Gbps LAN plus iSCSI hardware offload). oFCoE Converged Network Adapter (CNA) (10Gbps LAN plus FCoE hardware offload).
TIP: When you change the mode of the port (Ethernet/FC), you need to reboot the switch. On Nexus 5548UP you can assign the FC ports, but you need to start from the END of the ports in the modu…
