that adheres to M1000e recommended
practices for blade IO configuration
• Switch FW can be upgraded without
requiring network to be brought offline
•
All blade server Ethernet ports used for SAN
reside on the same mezzanine card
resulting in a potential single point of failure
• Spanning Tree must be considered if
uplinking SAN to external switches or
additional M1000e enclosures
