Cisco 3750 vs. 4948

We are currently purchasing new switches for our servers in our datacenter. We cannot fit a 4500 series switch in our budget so we have been looking at either 2 3750-48 switches or 2 4948 switches. At first glance we thought the 4948 were the obvious choice, but when we had them quoted they came back cheaper than the 3750's. Does the 3750 do something the 4948s do not? One thing we do want to do is LACP for all 40 servers in our enviornment and etherchannel to the routers. I know the 3750 supports 48 channel groups, but I couldn't find any specs on the 4948.

Hi friend

The 3750 supports cisco stackwise technology which is not supported on the 4948.

ALso you have POE options with the 3750.

THe 4948 on the other hand gives you redundant/hot swappable power supply options

and has a higher switching capacity.

You should be good to go with the 4948 if you want to connect your servers and do LACP

HTH, rate if it does

Re: Cisco 3750 vs. 4948

Hi,

I would suggest to go for 4948's. These switches are the ideal for data center servers with a complete non-blocking architecture.These switches provide line rate wire-speed 96Gbps backplane switching capacity. Where as 3750's only support 32Gbps backplane.If I were you, I would have certainly looked for 4948's.

HTH,

amit-

Thanks for the reply. We have always been leaning toward the 4948 for the reasons you pointed out. It was just a little concerning when the 4948s ended up being much cheaper.

Re: Cisco 3750 vs. 4948

Given the specs on the new 3750E series (68Gbps backplane), is the 4948 still considered a much better switch for server farms? We have around 150 servers, and the stacking feature is very attractive, but the 32Gbps backplane on the older 3750 series always kept me away. Now with the new architecture of the 3750E, we are leaning toward them as opposed to the 4948.

Thoughts?
