HP Procurve Topology and cabling advice
Posted on 2007-12-06
I have 2 HP ProCurve switches and need some cabling advice. I'm trying to enable the most efficient network with the best throughput.
The network supports 40 users and 3 servers. The users' workstations are all operating at 100MB through an HP ProCurve 4000m switch (which has a card with one Gigabit port). The servers are all connected to an unmanaged HP ProCurve Gigabit switch. Two of the three servers have dual network cards and I have them homed to a single IP address in each server. One server has a single network card. All network cards are Gigabit and all servers network cards are plugged into the Gigabit switch. A single certified CAT6 cable connects the two switches from the Gigabit port on the ProCurve 4000m to a Gigabit port on the Gigabit switch. The crossover is controlled by the auto-sensing port on the Gigabit switch.
I run a single private subnet (172.16.0.x) and isolated the servers on the Gigabit switch to gain better network throughput during my overnight backup cycle. Because theres only one cable between the two switches, all users who open files from the server (every user all the time) are experiencing data flow through a single cable and there is a single point of failure.
Im generally satisfied with the speed and observe few collisions, but Im no thrilled with depending on one cable between the two switches. Ive never had a failure and Ive never had a problem, but Im suspicious that this setup is not as efficient as it could be.
For the two servers with dual network cards, would I be better off plugging one card into the 100MB switch and 1 card into the Gigabit switch? Is there a better setup that I havent contemplated? Thanks in advance for your help.
