    What's a decent 48port gigabit switch?

    I'm looking to get our first full rack at the end of this year/beginning of next, just wondering what switch people would reccomend?

    Most likely we'll end up with a single 1000mbit drop, and ~30 machines.

    Although Netgear isn't my personal preference, how would a Netgear Prosafe GS748T do?

    We are on a budget however I want something which is going to be bulletproof and not cause us any issues.

    Thanks

    we use prosafe switches in office environments, I dont think I would recommend it for a rack though. More likely an HP procurve as I think they are more tolerant to the temperature differences that can happen in a rack. Their backplane is also much higher than the prosafe ones.

    You can pick up PowerConnect 5448's for very little if you bundle them with server orders and they seem to be pretty solid.

    You could try an HP Procurve or a Cisco Catalyst depending on what "on a budget" means. AFAIK NetGear is a consumer brand, similar to linksys.

    We are using 48 port Gigabit switch from Netgear for one of our private networks - multiple terabytes of traffic goes through it for backup purposes and it works fine. It is very cost effective solution and I think it has a very nice web interface with good features.

    Stay away from Dell Powerconnect. I used them a number of times for critical infrastructure and they puked under pressure.

    That's my experience. I stick to the HP Procurves or Cisco Catalyst myself -- usually the HP's since they have lifetime warranties and are super easy to use with intuitive web management. If the feature is advanced though, you have a full telnet/SSH CLI to configure the most advanced features just like a Cisco.

    That is my main complaint with the standard image Catalysts, actually. You have to use rsh unless you buy a "crypt" image. When you're paying a couple grand is an SSH server so much to ask for?

    If you are looking to pass full 1000mbit traffic i would suggest go for cisco 3750's or 4948 catalyst if your budget allows and if u r looking for reliability for long term. Otherwise dell powerconnects are also good options you can look for them on ebay and might get a good deal.

    A Cisco 3560 sounds like it may work for you.

    Thats strange. I asked once about Netgear and people basically screaming to my face to stay away for it. How old is it now and how much traffic is it pushing it exactly?

    Hey there,

    Why not an HP 2848?

    You can ebay them for around $400 - $500 w/ free shipping these days.

    Thanks,

    I think unmanaged ones are not good - we had several failures during last 5 years.

    The managed one - 48 Gigaswitch is pushing on daily bases several terabytes of backup data and once per week up to 20 terabytes of data and is OK for more than 1 year.

    Well I assumed we where always talking only about managed ones, I would not even use on a small office unmanaged ones, maybe just at home for connecting the Wii and the Wifi. There is always something that needs to be tweaked and for a DC managed is the only way.

    Well, I cannot assume they are great then if you only push backups, as its always the same traffic and almost the same size at the same times. I thought it was infront of public servers. Thanks for sharing.

    You're welcome. I did mention in my original post that this switch is used on one of our _private_ networks.

    I missed that one. And what switch do you use for productions environments?

    In our newest data center (third one) we are using Cisco 65xx (09 and 13) for access for our customers (cabinets only).

    Cisco Catalyst 3750G-48TS would be my vote.

    Cheers for the suggestions guys.

    We've got a 1000mbit drop purley so we have a bit more bandwidth to work with in the event of DoS/DDoS, although actual usage is going to be 50mbit-100mbit

    They are bit to expensive for a rack setup. Maybe for a small DC

    You mean the ones you colo cages or the ones you builded from scratch?

    If it was me I would say that from real worl expierence you might be better off getting a 48 port 100Mbit with 1Gbit uplink. This will mean if one user does decide to send outbound DDOS you aren't going to get setup with a huge bill. That said I would go for Dell Powerconnects myself as never had a major issue with them if coupled with an RPS

    Thats a nice tip but how about server to server connections? They would also be limited to 100 Mbps only. You could limit the port per server if you need to on Gigabit switch for each client you don't trust. To be honest I dot see any benefits going today with a 100 port switch as we are entering the 10Gig era.

    I wouldn't expose external connectivity to a switch, regardless of whether it was using a plain text or encrypted protocol.

    Keep network devices on private or non-advertised IP space; if you need external access, use an ACL on your edge routers and/or use a bastion server. Cisco IOS has had its fair share of security vulnerabilities over the years.

    The lowest end switch I would consider is HP2824. We used HP switches in production for a number of years when our network was relatively simple. We continue to use a pair of HP2848 for our internal / corporate network. Beyond that, you can look at:

    Cisco 2960G (layer 2)
    Cisco 3560G (layer 3)
    Cisco 3750G (layer 3)

    Note, that with HP, only use it for layer 2.

    Either way, you are looking at a few grand for a good quality 48 port gig switch. If you just want gig uplinks, look at Cisco 3550-48 (if you will not need to support IPv6) any non G version of 2960, 3560, 3750. Also note that Cisco 3560 and 3750 are basically the same switch, except 3750 is stackable, which is nice if you plan on adding an additional switch / uplink ... you can deploy a fairly redundant network layer to all of your servers, assuming they have dual NICs that can do teaming.

    If you need inter-vlan routing on the switch, you will have to look at Cisco. Do not except NetGear, Dell, HP, SMC, Linksys switches to be able to handle any sort of layer 3 routing effectively, particularly under a DDoS.
