We bought two clusters recently. Both clusters shipped with RJ-12 to female DB-9 cables for attaching to the serial consoles of the IB switches.
The True Scale / Qlogic 12300 ships with an RJ-12 console port, so the included cable works great.
The True Scale / Qlogic 12800 ships with a male DB9 console port … so the included cable … doesn’t do much.
==> Sounds like this is a gap -- I suspect that Intel intended to bundle some other sort of cable (from my point of view, a USB to female DB would have been ideal) with the 12800 ... but instead bundled the RJ-12-to-female-DB9 which is useful with the lower-end models.
I would like a single cable which connects from a USB-equipped laptop to a male DB9. Anyone else solved this?
Nobody else outside of Isilon engineering has likely solved it, because to be frank no monitoring or configuration of the switches themselves should be necessary. I always joked when I used to install Isilon clusters, that if we could get the IB switches dumb instead of smart, and at Staples or Best Buy, then we probably would. The intent of that statement was to drive home that the cluster monitors the health of the IB fabric itself, and it'll let you know if there is a problem. But absolutely zero configuration or monitoring of them from the outside network should be necessary.

The cables & connectors should have came along with the Infiniband switch. It needs an 1 x RJ12 cable connection and a 2 x RJ12->RS232 connectors.

Agree with what Chris K. says. An alternative is to use the IP ethernet connection.The IB default IP & subnet is
192.168.100.9 255.255.240.0.
