I'm not really sure, for raspbian wheezy we use eight imx53 quickstart boards. Now an arndaleboard should be more than twice as fast as an imx53 even in non-parelellisable builds but debian is growing over time. I'd guestimate six arndales would be enough to do us for a while.For a build cluster the arndale board looks way better than justlaptops.1. How much of them will you need ?
2. It may be difficult to put the arndale board into a case which can be mounted into a rack. It looks like the arndale board has itsThe arndaleboard has connectors on three sides but one side only has HDMI which we would not be using so there is no need to leave space to plug it in. The arndaleboard is 140x195mm.connectors at least on 3 sides of the pcb which doesnt't make it easier.
You can easilly find 1U cases that are designed to take an EATX board. EATX is 305mmx330mm. If the long edge of the arndaleboard is placed along the short edge of the space with the connectors facing inwards that gives us 50mm of connector space between the two boards for connectors on the long edge and 110mm of space for the eSATA connector on the short side.
So I think two arndaleboards in a 1U EATX case would be tight but doable. The biggest problem would likely be the serial console connector and it may be nessacery to use a custom cable for that either using an IDC D connector or using a conventional solder or crimp connector with no backshell.
3. Which interface would you like to use for mass storage ?
SATA
