Cisco Nexus 7000 upgrade to 8Gb

When upgrading a Nexus 7000 to NX-OS version 5.2 (using more than 1 VDC) or to NX-OS v6+, Cisco claims the need to upgrade the system memory to 8Gb.

Note I have run on v5.2 using only 4Gb per SUP using 2 VDCs and it has worked just fine, but I should mention that the box was not under heavy load.

See how much memory your N7K has on a SUP by using the following command:

N7K# show system resources
Load average:   1 minute: 0.47   5 minutes: 0.24   15 minutes: 0.15
Processes   :   959 total, 1 running
CPU states  :   3.0% user,   3.5% kernel,   93.5% idle
Memory usage:   4115776K total,   2793428K used,   1322348K free

The upgrade per SUP would need the Cisco Bundle upgrade package (Product code: N7K-SUP1-8GBUPG=). One package has one 4Gb module. (see picture below) If you have two SUPs you would need two bundles. Notice the 8Gb sticker on module in the red block.
