comment ext4 production ready on kernel 2.6.32 (debian6)?
Bugfixes are already done by LTS (long term support) kernel maintainers. Backporting new hardware support and features is crucial for Enterprise distros, otherwise for example you would not be able to run RHEL5 on modern hardware at all. Also if RedHat would not backport features from recent kernels it will loose customers. Anyway just look at release notes of RHEL 6.5: access.redhat.com/site/documentation/en-US/… and look for has been added or support for.

By backports I meant porting linux kernel features from recent kernels back to 2.6.32 without breaking API/ABI e.g. new versions of drivers or sometimes new features.

It's worth mentioning that RedHat 2.6.32 has a bunch of redhat-specific backports from recent kernels, so it can not be compared to Debian's.

comment Should I set rto_min for a route inside data center?
@Janning max latency is proportional to cumulative size of all buffers along the way. Speed of light is negligible in your case.

comment Should I set rto_min for a route inside data center?
I guess rto_min should be set not with regard to current latency, but w.r.t. sizes of buffers along the way and bandwidth. For example in presence of traffic bursts switch/router can hold frame/packet for couple of milliseconds.
