The PS4210 have 2x SFP+, 2x 10G BaseT and one single MGMT Port.  The BaseT are downwards compatible to 1G. So your PS would be connectet by 2x BaseT per Controller where one controller is active and the 2nd. is on standy. So you may able to see 200mb/s depeding of how good MPIO will works. Thats not a problem because the current PS line doesnt contains specific 1G models any more like in good old day with the PS6010<->6000, 6110<->6100. So you doesnt have to made a  decision when you buy the unit. You get both option in one box and can change it when ever you like. Regards Joerg
Hi there, I've been asked to install the below :- My concern is that we would be using a 10GB SAN with a 1GB switch (and 1GB NICs on the server).  My colleague said the Equallogic can connect to the 10GB uplink ports on the switch but the servers will only be able to connect to the server at 1GB, I'd be interested to hear if this is considered good practise - I don't like the sound of it! -Huw 
10GB SAN with 1GB switch?
