We upgraded our Cisco UCS environment, every host got extra memory from 128 to 256GB. Before we did it we had mesured CPU usage by VMware vRealize Operation Manager. It was a great help to this process. We ware able to proof the CPU performance will be ok with this memory size. We would have liked to incrase our VMware environment density.

We had to coolect every memory module serial numbers, and information about that witch chassis consist of witch memory modul.

We used to Cisco PowerShell for this task. Yes, exist PowerShell tool for Cisco UCS 🙂

You can download Cisco UCS Power Too pack (click link) and install your computer.
(You must restart your computer after install process)

Collect memory serial numbers, and UCS chassis information:

Get-UcsMemoryUnit | Export-Csv c:\tmp\UCS_Memory.csv -Encoding utf8

Get UCS chassis serials:

Get-UcsBlade | Export-Csv c:\tmp\UCS_Serials.csv -Encoding utf8

Whit this two Excel you are able to determine witch memory modul are witch chassis.
