Cisco supports the design and implementation of high-speed Fibre Channel fabrics, leading a change to the traditional FSPF link cost calculation for 128 Gbps serial interfaces due to the Cisco-only capability to create logical links with up to 16 members.

New trends in datacenter networking, and uncertainties on the data-dependent compression ratio, are clearly suggesting that 25G FCIP is the best approach to address remote data replication needs. Cisco MDS 9220i is what you need for your high-performance and secure SAN extension projects.

Cisco MDS 9000 Series provides all necessary capabilities to eliminate the noisy neighbor syndrome at the storage network level. By combining proper network design with high-speed links, congestion avoidance techniques such as DIRL, slow drain analysis and SAN Insights, IT administrators can deliver an optimal data access solution on a shared network infrastructure. 

The joint adoption of Cisco UCS compute systems and Cisco MDS 9000 Series of storage networking switches provides a significant benefit to the enterprise: advanced design options, easier management and better support.

Current sustainability efforts require power-efficient solutions that can deliver more bandwidth at a reduced wattage. Cisco recently introduced 48 ports on the Cisco MDS 9700 64-Gbps Fibre Channel Switching Module, a real technological breakthrough. Increased bandwidth, combined with approximately 40% decrease in power consumption makes it about 7 times more power efficient than its predecessor.

Troubleshooting MDS 9000 fabrics starts from collecting tech-support files and contacting the Cisco TAC. What is the suggested approach for doing so?

Data volumes keep growing, budgets are not. The workforce is highly mobile and distributed, applications live within hybrid-clouds, the edge of networks is now hosting data and cybersecurity is clearly a top priority.

Dynamic Ingress Rate Limiting represents the newest and shining arrow in the quiver of MDS 9000 storage network administrators for addressing slow drain and SAN congestion situations.

SAN congestion is a real challenge and can manifest in different ways. In order to exemplify the concepts, we compare the SAN to a highway system. This blog has two parts.
