10GBit still far from ideal pricewise, £300 for a NIC and £1000 for a switch with 8 ports.
I would try infiniband for my labs but not for production.
Problem is my Veeam backups are saturating easily the gbit network, the backup server has a big and fast RAID-5 array, writes sequentially at around 950MB/sec. My problem is the network being the bottleneck now.
Thanks!
