Table 34 Single enclosure link aggregation single fabric
Single fabric non-stacked configuration
Advantages Concerns
Consistent M1000e fabric management 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
Table 35 Single Enclosure Link Aggregation Dual Fabric
Dual fabric non-stacked configuration
• Ensures that Ethernet SAN ports on each
blade server will be distributed across two
different mezzanine cards for a more highly
available solution
• Switch FW can be upgraded without
requiring network to be brought offline
• Does not adhere to recommended practices
for M1000e blade IO configuration
• Spanning Tree must be considered if
uplinking SAN to external switches or
additional M1000e enclosures
