It would be much less embarrassing for you if the website in your signature actually finished loading the images containing the text for your company. The page does not render at all for me -- it is completely blank once the gratuitous code stripper is finished with it. I presume security has to be disabled to view it -- and I'm not going to do that. As a matter of policy I never deal with anyone who is so incompetent as to create web sites like this. Generally I have found that such companies product is of the same quality as the web page.

The Juniper ex4500/4550 could work, small chassis, can be made part of a virtual chassis. Works well in an enterprise setup but can cause configuration headaches if within a service provider environment where vlans need to be translated.

Re: Looking for recommendation on 10G Ethernet switch
You may want to take a look at the Brocade VDX 6720, it provides 16 10gb ports, with 8 ports on demand with addl license. They are very reasonable, esp. if you only need 16 ports.

Certainly the days of doing NxGE to servers should be behind us. There are many good 10GE switch offerings. The Juniper QFX and Arista (insert one of three good product lines here) have been excellent for us. We like them for different reasons -- Arista is quite good if you want to integrate with a provisioning system; QFX is our choice when most provisioning is done manually. Both are way under $50k per box. The biggest difference between the TOR-style switches and chassis offerings, aside from the obvious, is buffers. All the TOR-type 10G switches have really small buffers and that can be a performance issue for iSCSI when utilization is high. Most of the chassis-type switches have very generous buffers so you do not run into problems with micro-bursting, etc. The vendors will all tell you about lossless ethernet, flow control, etc. and that crap sounds great on paper.

The vendors will all tell you about lossless ethernet, flow control, etc. and that crap sounds great on paper. Try making it actually work. flow control on a switch port can lead to hol blocking, which is bad bad news - guaranteed to trash multi-access network performance. Some vendors actually push this as a feature. I don't completely understand why, but maybe it has something to do with customers mistakenly believing that it will make their lives better. People believe in all sorts of odd superstitions though: black cats, spilling salt, having full features on ethernet LAGs, vendor marketing blurb, fear of the number 13, etc. All very odd stuff. Nick

I'm also currently looking for 10GBASE-T switch for my first SAN, but one with 48 ports. The price for X670V-48T seems reasonable, but I have no experience with 10 GbE over copper, so it's difficult to figure out what criteria to use (other than price) when comparing Extreme, Arista, Dell, and others.

Re: Looking for recommendation on 10G Ethernet switch
I have used the summit x650s for cloud and they work fine for public and SAN traffic on the same switch. I have seen then as low as 7k if you can work with extreme directly. The only downside being the configuration for large VLAN amounts. Also netgear makes the xsm7224s which does everything the summit does aside from only supporting 1024 vlans. I have a pair of these and they work very well. On Friday, November 2, 2012, Andrew Latham wrote: On Fri, Nov 2, 2012 at 2:38 PM, Kevin L.
