Dan - re: "Blades" are an attempt to Clone SUN's successful architecture with PCs"

The first problem with your post is that Sun does not have a blade architecture.

Sun's CompactPCI designs are aimed at the telecommunications market - and that is what CompactPCI was developed for in the first place. Take a look at sun.com to see a little about how Sun positions that product line.

You call it successful - can you give me even a single instance, anywhere in the world, where Sun's CompactPCI design was used outside the Telco market?? Sun is not a competitor in the Blades game at the moment. And given Sun's primitive clustering capability, there is no way their design could do anything aside from what it was designed to do - provide simple dedicated processors for telco.

For example, can you show me Sun's system configuration using their CompactPCI boards? Hmmm - looks like Sun doesn't even make the rack products, they expect the Telcos to already have the racks.

Sun's design, like HP's, delivers no architectural innovation - it simply puts a small processor / memory combination on a single board and allows outboarding of peripherals via PCI bridging. There is nothing that this design does that could not be done with independent boxes in a rack - the CompactPCI design just makes wiring for I/O and power a little easier. It is not an SMP design or anything close to it.

The RLX blade design - see rlxtechnologies.com for details -
incorporates complete machines with their own local storage in a compact backplane arrangement which allows them to sell a complete product designed for dense web applications. Compaq's product - Announced with Intel in itworld.com - also include everything needed to actually make a working system for traditional applications. Their next generation infiniband products will allow more SMP like configurations, and will actually include SMP blades in at least 2P and 4P variants.

In other words, The Sun product has nothing to do with blades architecture, Sun is not in that market, they don't make a blade system, they only have a component for telco which happens to use the same form factor - and you are talking through your hat.
