Hello, CT's requirements in I/O depend on an user application. 1 Gbit link is enough to supply up to 100 MB/s I/O in PStorage. Moreover according our statistic HSPs usually have 10-20 MB/s I/O per node, running tens of containers, because I/O is almost random. So, 1G network should be enough for usual scenarios. We have many customers with 1G storage backend in production.
BTW, with PStorage you have an additional benefit: According our statistic 20% of nodes process 80% of I/O in DCs. When you unite disks into one cluster you have better I/O balance.

As far as I understood, pstorage is in fact targeted towards clusters with hundreds of containers, so I am a bit curious to understand where you got that information. If there's anyone on the list that has used pstorage in clusters > 7 - 9 nodes and wishes to share his or her experience, that's more than welcome.
