Hi Jim, The customer who owned the 3048 switch we were trying to use in a cluster ended up pulling it for project deadline reasons -- we just did not have the time or interest in debugging the 3048 lockup issues we saw when the unit was under heavy NFS load. My understanding is that the 3048 now is being used in a desktop setting without any problems (rather than being returned). We ended up replacing the Dell Powerconnect 3048 switch in that cluster with a Dell PowerConnect 3248 model which has more features than we really needed but does have a totally different internal firmware, embedded OS and management interface. It may even be Cisco under the hood (not sure) The 3248 has been working flawlessly -- it aggregates traffic from a number of compute nodes and is uplinked to an ExtremeNetworks Alpine 3808 core switch. On other projects I've used the following Dell Powerconnect switches without any problems at all: Powerconnect 3024 -- 24 port 10/100 switch with dual GBICs Powerconnect 5012 -- 12 port gigabit ethernet (copper) switch Powerconnect 5024 -- 24 port gigabit ethernet (copper) switch So- we never really solved the 3048 problem. My understanding at the time was that this was a huge priority for Dell to fix because I think that was the switch they were trying to use on the monster Dell SUNY Buffalo cluster. Its bad to hear that they still have not nailed the issue. Dell seems to OEM different internal firmware and embedded OS's for various units in the powerconnect line. This may be why the 3048 is a dud and the other switches have worked fine for me. I'd recommend repurposing or replacing the Powerconnect 3048 switch. It just can't seem to stand up under heavy NFS trafic. Overall though I'm still pretty happy with the Powerconnect line -- in particular I like seeing a 24-port Gigabit Ethernet switch for under $2,000 USD. -Chris Jim Kehres wrote: > Hi Chris, > > > > I saw a post on a board from August from you concerning problems with > the Dell 3048 switch.
