Grid Redundany in Cisco MDS

[msingh08]

This is with regards to Cisco MDS 9718 Multilayer Director, what is Grid Redundancy and does the director by default come with power supply units, what is the minimum number of power supply units I can have and how many number of power supply units are needed for grid redundancy

Hello,

For the MDS 9718 Grid Redundancy, the minimum number of Power Supplies

depends on the Modules installed. 

Please see:

Table 5-19 AC PSU Requirements for Grid Redundancy

https://www.cisco.com/c/en/us/td/docs/switches/datacenter/mds9000/hw/9700/mds_9700_hig/techspec.html#72679

Here is the ordering information:

I hope this helps you.

Carlos

In the Cisco MDS 9710 Director Overview document, figure 1-1 needs to be updated to properly reflect the components of the Chassis. Details of grid redundancy for the MDS 9710 switch needs to be documented.

1-    System LEDs
2-    Rack-mount bracket
3-    Switching modules (1 to 4)
4-    Supervisor modules (1 to 2)
5-    Switching modules (5 to 8)
6-    Power supply modules
7-    Handles used for adjusting the chassis placement

Needs to be updated as follows:
#3 - Switching modules (1 to 8)
#5 - Power supply modules
#6 - Handles used for adjusting the chassis placement
#7 - N/A

Also, details of power supply grid redundancy (Grid A and Grid B) as well as slot location should be documented.
