This has caused me to lose sleep and not get my weekly pat in the back from my boss.
We have a web hosting related product that consists of database, bandwidth and I/O sub-products.
To represent the database, I'm using a "three ringed" database tower. To represent the bandwidth, I'm using a chart-like graph. In my particular case, "bandwidth" really refers to data usage and I/O refers to the way we speed up disk performance, using specific drives and working with the Linux kernel.
Those seem to work for 85% of the people to whom I have access.
But what in the world does one use to represent I/O?
Showing the small letters i/o has been rejected, because it's too obvious. Seriously.
Any other ideas or suggestions from anyone?
