Has anyone had any experience with the Dell PowerConnect 2724 Gigabit Switch and VoIP traffic? It seems to support Class of Service (CoS), but not full Quality of Service (QoS). Will CoS help prioritize VoIP traffic at all? I am setting up an asterisk PBX for 22 users with very light traffic, but I don't want to have the call start skippin...

...9;'ve locked up my dom0 a couple of times this morning copying a 3GB file from local disk to an NFS mount(neither xend nor guests running). I don''t encounter this problem on the stock CentOS 4 kernel. The machine is a PowerEdge 2850 with 2 e1000 cards - the one in use is connected to a PowerConnect 2216 10/100 switch and has negotiated 100Mbit. I''ll check if the stock Cambridge isn''t negotiating full duplex but that shouldn''t cause lockups. My mount options are: defaults,intr,rsize=32768,wsize=32768,nfsvers=3,tcp,timeo=600 This isn''t at NetApp (no 100Mbit...

Grasping at straws here...is anyone using a Dell PowerConnect 2224 24-port unmanaged 10/100 switch in a deployment? I have two separate asterisk installations with bad one-way audio where the only common elements left are the Dell switches and Polycom IP-500 phones. Two different ITSPs - one location uses IAX2 to the outside world, the other SIP. Two diff...

So has anyone had any experience working with the polycom 501 or 301 and vlans? We run dell managed switches here, so we don't have the luxury of running CDP to force the VOIP vlan. I haven't been able to get the polycom phones to talk on a manually set vlan. I have some junky sipura phones that work fine-(get dhcp, register to asterisk etc) when i manually set them to vlan4. Any advice

Hello all, I have leased 1/3rd of a rack (14U space) in a top notch data center. I''ll be racking a layer 2 managed switch (a Dell PowerConnect 5224), four of my own servers (1U Opteron servers, single socket, dual core, dual NIC), as well 2 servers for 2 friends who will be subleasing from me. The package includes 6Mbps of bandwidth, burstable to 100Mbps. Bandwidth is tracked with 5-min samples, and as long as my 95th percentile...

I'm looking to acquire a few new core switches for our network which would be a major upgrade from the cheap unmanaged things we currently have. Basically, just users, servers, and other simple network devices will be plugged into them but I'd like to start doing some testing with iSCSI for various non-production reasons. I have no allegiance to a particular vendor although I do have a

Hey, all. We're rolling out VoIP, and I'm wondering about PoE recommendations, as we're going to have to replace our current network equipment. My first inclination would be to just plunk down the cash and do a Cisco system, but I'm relatively certain that would get shot down by finance. Any recommendations for a couple-hundred-port solution with VLANs, PoE, and QoS? Don't
