We are proposing to patch a group of servers with GB NIC's directly into a 10/100/1000 blade in a 4507R. What type of patch lead would be suited to give the best performace (using RJ45 connectors at each end).
Category 5 or better unshielded twisted pair, with all four pairs connected in a straight-through pinout configuration, is all you need.
Anything rated higher than Cat5 (for example, 5e, 6, 7) is tested to higher megahertz signaling levels; and may also have increased resistance to electromagnetic interference (EMI) and cross-talk due to a higher number of twists per foot/meter in the pairs. But the Gigabit Ethernet 1000BASE-T standard calls for minimum Cat5, and you're good out to 100 meters.
If you're under 100 meters and a cable tester doesn't certify the run as Cat5, and you're using all Cat5-rated components (cabling, connectors, jacks) and installation techniques, then it's time to start thinking about fiber, which is immune to EMI.
It doesn't hurt to have higher-rated copper, though. Think of it as insurance: good to have, but you probably won't need it.
Just don't wrap the cable around power transformers, UPSs, fluorescent lights, or elevator motors, and you'll be fine.

Hi, I am seeing quite a few issues with patch install and wanted to
share my experience and workaround to this. Login to admin via CLI, then
access root with the “shell” command Issue “df –h” and you’ll probably
