I'm building a small datacenter from the ground, and I'm considering 10GbE. I'm looking for some advices about this decision.
I've compared Infiniband, FC, 10GbE and LACP with GigE, and in the end 10GbE appears to be the best solution at this moment.
Talking about the datacenter: it will have one or two storages (two in case of failover scenario), and three 1U machines running some Hypervisor (XenServer is my favorite). The VM's will be in the storage, so the Hypervisors will boot from the storage or I will put some small SSDs in the 1U machines just to load the Hypervisor.
So, the problem here is: I'm little confused with what I've to buy to make the network. I've saw some expensive switches, like the Cisco Nexus 5000/7000 with a lot of features but I don't know if I really need this guys.
I don't have FC, so it's safe to buy single 10GbE switches without "converged networking" technologies? Or I should take one of those to get FCoE running?
Another question: iSCSI over 10GbE would be better than FCoE? (I'm considering FCoE is better because we don't use the IP stack in FCoE).
Thanks in advance, and I really appreciate some opinions here.
