Blade Network Technology has rolled out the RackSwitch G8052, a new addition to its top-of-rack switch lineup.

Finally, network kit that cools properly
Congrats to Blade Network Technology for building a top of rack switch that won't completely screw up your server cooling and data centre efficiency.

Who buys TOR 1GBe switches?
Lots of people.
Looking at Blade Network's 10GBe offering, it retails around 13K (USD) versus 6K (USD) for the mix of 1GBe and 10GBe.
This switch actually makes sense. In building a Hadoop Cloud, a node w 8 2TB SATA drives will experience a bottleneck on disk i/o before hitting a 1GBe networking bottleneck. (YMMV) but you can cheaply solve this via port bonding. Then you'll only be slow on the trunk (uplink) from rack to backbone. There the 10GB should be enough...
So the product fits an immediate need where customers can't yet justify the higher cost of switches and nic cards.
Re:Finally, network kit that cools properly
Actually, Arista Networks switches have configurable fan direction. No need to order a different unit, so you can move a switch from a top-of-rack to end-of-row configuration.
Who buys Gb switches?
That'll be me, I'm just in the process of purchasing 8 of them.
