Virtualization brings numerous advantages to the data center, including:
However, it also introduces new challenges, especially for SAN deployments in virtual machine environments. These challenges include:
Cisco MDS 9000 Family takes an innovative approach to address these challenges.
Cisco MDS 9500 Series Multilayer Directors with cross-bar architecture and design meet the most stringent performance requirements:
Quality of Service
You need granular traffic prioritization tools for application management across all enterprise applications in a virtualized, consolidated, physical SAN. The Cisco implementation of QoS is transparently integrated with both N-port identifier virtualization (NPIV) and VSAN capabilities. It has the following advantages over the competition:
You can prioritize your applications when building a tiered approach in virtualized environments within a certain tier (a storage tier fits well in a dedicated VSAN) as well as within each tier.
When virtualization and virtual machine mobility are considered with respect to security, the Cisco implementation of role-based access control (RBAC) is superior to that of the competition:
This brings significant advantages to customers when virtual machines are deployed in conjunction with VSAN and IVR features.
Note that Cisco MDS 9000 Family RBAC is as flexible as the RBAC provided by VMware vCenter, allowing the creation of parallel groups of administrators with very specific focus, to support related areas of the virtual infrastructure and the fabric.
