Hello,   The Force 10 is a great switch.  There are also 10GbE in the Power Connect line as well.  Either approach works. Replace existing, or lag over to a new stack for 10GbE.    Much depends on when and how you are planning to upgrade to the servers to 10GbE NICs.  What you need to prevent is 10GbE server NICs going to GbE arrays.   Have you contacted your sales rep?   They can bring in some network folks to review what you have now and help you move forward.   Regards,   Don 
Hi We have been running EqualLogic 6100's in production for 2 years now and I am considering the newer 10Gbit arrays. At the moment we currently use two Juniper ex4200 switches in both of our server rooms and they seem to be good. I have been looking for 48 port copper switches that do 10Gb and there doesn't appear to be much out there other than the Force 10 S4820T.  If we purchased these, would it be feasible to swap out the junipers and run the 1Gb arrays as they are alongside 10Gb arrays (different storage pool) and servers ? We could potentially create an lacp trunk between the junipers and these (as indicated in one of the best practice guides) but we are quite pushed for space in our networking rack. I was thinking that we'd stack the switches using 3 of the qsfp ports on each S4820T, would this be a bottleneck due to the ports being 10Gb and there only being 120Gb between the switches ? The other qsfp ports would have be used with spf+ optical transceivers for running replication traffic between our two server rooms.  Thanks
