We use more HP switches than I can count.  They work fine.

What we've found is, like our experience with Dell switches some 5-8 years ago, their switches blow.

Two of the servers run KVM, and when we start turning up virtual machines on the KVM servers, the Dell switch starts seeing CPU utilization spikes, we get packet loss pinging real servers attached to the Dell switch, the Dell's CLI gets sluggish, and the Dell will terminate telnet sessions (not because they're idle) to the CLI and sometimes stop accepting new ones for a short time.
