Hi folks,
We are still on the way of building our first small-cluster. Right now
we have 16 diskless nodes 8GB RAM on X7DWT-INF and a master also on
X7DWT-INF with 120GB disk and 16GB RAM. These boards (X7DWT-INF) has
built-in Infiniband Card (Infiniband MT25204 20Gbps Controller), and I
hoped that we can create a boot server on the master node for the 16
clients using IB connection.
Unfortunately after reading, I found out that our built-card is too old
for Mellanox FlexBoot:
$ lspci -v | grep Mellanox
08:00.0 InfiniBand: Mellanox Technologies MT25204 [InfiniHost III Lx
HCA] (rev 20)
Subsystem: Mellanox Technologies MT25204 [InfiniHost III Lx HCA]
whereas FlexBoot requires at least Connect2X-3X to work with.
My questions are:
* any body using the same (or similar main boards) and was able to
boot using PXE?
* if PXE server with Infiniband is impossible, then it is OK with a
gigabyte connection? Or should we go for 16 disks for these 16 clients
and dont care much on boot over IB or IP? (more money, of course)
Thanks,
D.
