Thank you all for comments,
So to sum up a bit, it's a reasonable compromise to buy :
2 x R720 with 2x Intel E5-2660v2, 2.2GHz, 25M Cache, 48Gb RAM, 2 x 146GB, SAS 6Gbps, 2.5-in, 15K RPM Hard Drive (Hot-plug) Flex Bay for OS and 24 x 1.2TB, SAS 6Gbps, 2.5in, 10K RPM Hard Drive for OSDs (journal located on each osd) and PERC H710p Integrated RAID Controller, 1GB NV Cache
?
Or is it a better idea to buy 4 servers less powerful instead of 2 ?
I think you are facing the well known trade off between
price/performances/usable storage size.
More servers less powerfull will give you better power computation and
better iops by usable To, but will be more expensive. An extrapolation
of that that would be to use a blade for each To => very powerful/very
expensive.
The choice really depend of the work load you need to handle, witch is
not an easy thing to estimate.
Cheers
