Cisco blades - or: I´m not really impressed

The big Cisco announced they entry to the server market. I expected something big. Well … i´m not impressed. The informations are a little bit sparse at the moment, but i will write down my thoughts about it:

• As expected the concept circles around their Nexus line of switches for combined FCoE and IP traffic.
• The cisco website states on product page that
  

  "Cisco UCS 5100 Series Blade Server Chassis supports up to eight blade servers and up to two fabric extenders in a 6RU enclosure without the need for additional management modules."

  This translates into 4 fullsize slots and 8 halfsize slots. for blades. This is considerable less dense than a Sun 6000 chassis with 10 respectively 12 slots on 10 rackunits.
• The blade system is even less dense than using 1 RU pizzaboxes. 1,25 inches for a single server as long you don´t choose the halfsize blades.
• The infos are a little bit sparse, but it looks like you can choose any kind of I/O for the blades ... as long it´s Ethernet ... no Infiniband, no FC, no SAS.
• Several points are unclear at the moment ... processor density for example, I/O capabilties, or the memory extender technology that Cisco mentions in a whitepaper

I hope there will be more information soon, but at the moment this fails at impressing me. I´m not really sure that just some Nehalem Blades with Ethernet, an Ethernet switch and reselling some software (they announced VMware, Windows and Redhat partnerships) is enough to convince the people of buying servers from their networking vendor.
