I cannot find any.


Xtreme CPU has not been known to do many networking reviews.  We want to change that.  We have been doing a lot of different networking jobs lately. So, I took it upon myself to write one of the first real reviews when it comes to the server/hosting market.  I have pretty good knowledge with Cisco, and HP’s Procurve line.  I do have to be truthful, I have not jumped full in to Juniper.  I hope everyone enjoys the review!

    What I’d like to see is a comparison of this unit, and others, against a home built router/switch using pfsense.

    We can definitely do that. However, I want to mention that this isn’t a home built switch. This is a enterprise level switch. There are things that this will just do better. Most home built stuff will have a very small backplane 2Gbit-8Gbit max, while this will do over 56Gbit/sec on the back plane. My follow up review will show what this thing will do 24/7 365. We’ve just put this switch into production 🙂

    You can certainly compare x86 home-built router with enterprise-level performance and features (e.g. Vyatta) to big-name routers that does the same thing. But this is a switch; there are no home-built possibilities here.

      Yeah. While this will do some static routing for you, it shouldn’t be used as a router. This should be used in conjunction with a router.
