I went over the review/test, and as far as i understood in this system there is only a single GLAN switch.
Besides, the individual nodes do not have their own HDD, but a NAS instead.
This is particularly bad, because the disk-I/O is also handled by this poor LAN switch.
One should use at least two switches: one for internode communication, and the other for NFS and so on.
Second point: if those prices which i have seen in the forum are right, than 20k$ is equivalent to 15600Euros.
For that money i can buy from the company where we are buying our equipment from the same system build from Supermicro 1U Twins. For this price i even have Dual GLAN per node, and one Infiniband per node.
This system above could be called indeed a computational server, and the Intel system is just something like a custom made weakly coupled network of computers which is coming with a hefty price tag.
Of course one could argue that buying 3 Supermicro twins plus an Infiniband switch is not as neet looking as this Intel, but once it is in a rack, who cares?
I would not really would like to listen to this intel machine on my desk anyway, so that should be put in a nice rack as well.
