Hi,
I'm just supposing, i'm also evaluating the same network topology like you.
I have tested my current setup for a while with just triple-bonded GbE, and haven't found the need for more features. I might be wrong ofcourse :-)
There is a lowcost. 12x 10GbaseT switch from Netgear.
I was looking at the Netgear XS708E which is very low cost compared to what the prices were 6 months ago when I looked at it last. What I don't know is how those prices compare to IB pricing.
on cluster network and IB to public network). Do you think will be possible to use all ceph services (RBD, RGW, CephFS, QEMU, ...) via SDP/rsockets ?
I haven't tried SDP/rsocket, so I don't know. From what I have experienced in the past, these things doesn't seem to be completely "drop in and forget about it" - there's always something that is not completely compatible with ordinary TCP/IP sockets.
On ebay there are many IB switches sold at 1000-1500$ with 24 or 36 DDR ports. If used with SDP/rsockets you should archieve more or less 18Gbps
That sounds cheap yes, but I assume that is used equipment? I was looking at costs for new equipment. -- Jens Kristian Søgaard, Mermaid Consulting ApS, jens@xxxxxxxxxxxxxxxxxxxx, http://wwww.mermaidconsulting.com/ -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
