    Replacing our core switch

    I have been told to go ahead and replace our core switch (as it is 6 years old and unwarrantied now). It is currently a D-Link DES-6000 with 6 x 16port 10/100 RJ45 modules, 1 x 12port 100Mpbs Fibre module, and 1 x 2port 1000Mbps fibre module. At the same time, we have 4 x D-Link DES1024 switches connected to it by 100Mb fibre around the school that I would be looking to replace also.

    What are people's suggestions? I have been advised various things already - such as using a D-Link xStack comprising of 2 x DGS-3450 and 1 x DGS-3427 and 4 x DGS-3024's for the edge switches.

    My key concern is that in the coming year we are looking at using our network infrastructure for VOIP and want to ensure availability and reliability of that system.

    I have been looking at moving to HP ProCurve switches instead. What advantages would I gain from doing this? (Other thank lifetime warranty, next day replacement etc...).

    Cheers,
    Tony

    Re: Replacing our core switch

    I use a 2824 HP Procurve as a core switch. 20 Gigabit ports and 4 dual personality ports which you can use the 4 RJ45 ports or get some GBICs and connect 4 Fibre pairs. If you need more than you are looking at a chassis and expensive .

    The HPs are very good value for money and the life time guarantee is great.

    We are willing and able to go for expensive.

    Re: Replacing our core switch

    We also use HP, the 4140GL switch..... it is slightly more expensive then the one that Chris mentioned, but it is expandable for the future see the link below for all the details

    HP 4140GL

    Again the warrenty the HP offer is very good, and what made me go with HP plus the quality of the product has been outstanding aswell

    Re: Replacing our core switch

    We've got a 4108GL as our core switch which is an 8 slot chassis and it's now completely full.

    The newer ones with mini gbics are good though for the fibre transceivers.

    Have a look at the HP 5412zl. 12 module slots and it supports 10GB fibre links. HP still class it as an edge switch and not a core switch though.

    Re: Replacing our core switch

    I had a similar conversation with an HP person last year as our 4108GL is not classed as a core switch by them either but I think for schools they are perfect to function as the core.

    Re: Replacing our core switch

    I had a brief (very brief!!) look at the HP core switches and they are ever so slightly out of our range (a 4 port fibre module was £11k!!), so I think we shall be living with edge switches masquerading as core switches.

    Re: Replacing our core switch

    Thats must have been 10 Gig modules Theres a configurator you can download from the HP site to help you and the prices give you an idea on pricig although you will get it cheaper.

    We have two 5406zl for our core.

    We did a complete network overhaul for around 40000k

    This included

    21 2600 series switches
    5 3400 series swithes
    2 5400 series switches

    including all the fibre modules, and network design.

    I started by getting HP to design and quote, then they passed us to a local partner who were exceptionally good, they took the HP design which was overengineered to the max, and visited our site and reworked the design .

    Re: Replacing our core switch

    Right, I have decided upon one of the 5406zl HP switches with 4 of the 24 port 100/1000Mbit modules and a 20 port fibre module and dual PSUs for the core and HP 2650's for the edge ones. (so 96 gigabit copper ports and 20 ports for use with mini-GBIC's).

    It was either that or a stack of Dlink xstack units for the core and DGS-3024 units for the edge ones.

    I chose the HP ones as they cost less!?! and have a better warranty by far.

    If you have it in your budget get the procurve manager software as well.

    It make life so much nicer when you make configuration changes.

    Re: Replacing our core switch

    Do the standard switches not come with the normal version? I thought they did and you paid extra for the plus version? What's the difference?

    You could be right, we went for the full everything as they are the only switches we use now, I'd check with HP.

    Netgear Prosafe GSM7324 L3 Managed

    We recently purchaced one of these to replace our core switch, and saw a great improvement. We are all copper however, so I cant comment on its fiber performance.
