Denny Cherry Denny Cherry Profile: Denny Cherry

Hopefully by now everyone knows that they should be aligning your disks.  Now when you use a Storage Array to present the LUNs to the server you may have the option of offsetting the LUN so that you don't need to offset the disk.  If you don't plan on using any of the advanced clone or snapshot...

When using an EMC CX array don’t plan on changing the port that you use for MirrorView

When joining fiber switches together you won’t get the bandwidth you think over that link cable.

Telecommuting is awesome, except when it sucks.

Denny Cherry Denny Cherry Profile: Denny Cherry

Telecommuting is the holy grail of IT work. You save a ton of money on gas, and you don't have to work in a cube farm. You can decorate however you see fit and wear what ever you'd like to (or as little as you'd like to) when you work. However everything isn't all roses and puppy dogs...
