I am in the process of scaling up a Datacenter to handle what over the next 3 to 5 years is expected to be a doubling of the current workload. I am pushing my current stackable switches to the limit at peak times and the performance impact is very visible even to end users.
I am managing a network with approximately 1000 nodes.
multiple SQL servers for medical records and imaging (lots of data) SQL servers for financial data, admissions billing all the standard stuff. we are also doing a lot of Voice over IP and Voice over WiFi. we have 25 different VLANS, and obviously we have to deal with regulatory requirements for logging, security, availability etc.
I have been working on updating the Core Switching and for the various buildings and remote sites I have had no problems with the midrange 3Com series of switches the 40x0's. Of course they have just been end of lifed and I dont think that they will be really capable of handling everything in the core that we are going to throw at them over the next couple of years, so....
I have narrowed my choices down to a Cisco 6509 or a 3Com 8800. both switches claim to have the modules and support for the various protocols I am going to be throwing at them. (gigabit ethernet, 10 Gigabit ethernet down the road, OSPF, QoS, VLAN Access controls etc) I am not looking outside of 3com or Cisco as I really dont want to go down the road of learning a brand new interface and command language. Does anyone have experience positive or negative with either switch that they are willing to share with me.
