now for the next project I would like to entertain the use of SAS storage arrays for example:
three of these set up as JBOD
https://www.ebay.com/itm/K2R84A-HPE-MSA-2040-ES-dual-SAS-12gb-C8S53A-controllers-SFF-Storage-San/303211316131?epid=2261482182&hash=item4698cd83a3:g:uGYAAOSwNTNcWGt9
K2R84A HPE MSA 2040 ES dual SAS 12gb C8S53A controllers SFF Storage San
each one attached to a 12gb/s card on a 12gb/s 1U server with max core and ram requirements
what do you think? would there be a bottleneck issue with regards to the 12GB SAS connection per server? or would the petasan os see things differently? I would be raid 0 on each drive / jbod
anyone ever done things this way?

In most other workloads with smaller block size, your cpu cores will most probably saturate long before.
