Cisco N-Port Virtualizer for Large-Scale Fibre Channel
Blade Switch Deployments
Blade Switch Deployments
Blade switch depoyments are increasingly common among enterprise customers. Gartner
claims that blade servers are the fastest growing segment of the server market. This
trend means that Fibre Channel attach rates for blade server enclosures will also grow.
As the scale of blade server deployment increases, however, it introduces some
challenges, such as large increases in the number of domain IDs, increased server and
network management complexity, and interoperability concerns in multivendor
environments. The Cisco
®
N-Port Virtualizer (NPV) feature introduced in Cisco MDS 9000
SAN-OS Software Release 3.2(1) addresses these challenges, offering these features:
●
Increased scalability by reducing the number of Fibre Channel domain IDs used
●
Seamless interoperability between Fibre Channel blade switches and multivendor core
storage area network (SAN) switches
●
Enterprise-class high availability
●
Virtual SANs (VSANs), for segmentation and fault isolation
●
Advanced traffic management
●
Increased operational flexibility for blade server additions, moves, and changes
●
Simplified Fibre Channel blade switch management
Introduction
There are two architectural models for Fibre Channel blade switch deployment: switch and host
bus adapter (HBA) models (Figure 1).
