RSSI – Received Signal Strength Indicator. Measured in arbitrary “Indicator” units (wiki). Note that the Apple airport utility reports RSSI units as dBm, but that as stupid as saying “the link speed is 10Mb” or “the rainfall was 10ml”

IOM is the abbreviation for I/O Module according to https://www.cisco.com/c/en/us/products/collateral/servers-unified-computing/datasheet-c78-742624.html
Fully expanded that would be Input/Output Module.
The link to VIM – Virtual Infrastructure Methodology no longer works.
Hi Riaan,
I suppose I should update this. VIM doesn’t mean what it used to in 2012 when I posted this! Funny how acronyms change over time. I remember teaching classes where we used the Generic Attribute Registration Protocol (GARP) – but these days GARP is generally considered to mean Gratuitous ARP. In other words, it’s impossible to keep a page like this updated. Anyway, thanks for contributing.
CMIC – Cisco Management Integration Center (for UCS firmware management) is really know as
CIMC, with in the UCSmanager. Same words for each letter, but CIMC is pronounced SimSee.
Gotta love Cisco’s way – I’ll add CIMC as well!
Thanks
