Table 31 Connecting M1000e to Stacked External Switch Infrastructure
Connecting M1000e to Stacked External Switch Infrastructure
Advantages Concerns
•
Support configuring LAGs between M-series IO modules
across both external switches in stack (cross-switch LAG)
• M-Series IO modules’ firmware can be updated without
bringing SAN network down.
• SAN Array-to-array traffic is isolated outside of the
M1000e enclosures
• Fixed hops between hosts and array volumes regardless
of number of M1000e enclosures
• Supports ability to scale arrays
• Supports ability to scale host.
• Supports sharing SAN with non-M1000e servers.
• External stacked switches can be expanded by adding
additional switches to stack as more ports are needed.
•
Must bring external
switch stack down to
apply switch firmware
updates.
Other Notes
•
If available, use 10Gb links between M-series IO modules and external switches
• M-series IO modules do not need to be interconnected since no arrays are attached directly
to M-series IO modules.
• Additional M1000e enclosures are added in similar fashion to diagram above.
• This strategy works for a single fabric or dual fabric M-Series IO module configuration (See
Section 4.7.1.1 for details)
