inside multipathd.conf file "product" is nothing but to identify the MSA product that you are using where this config file will be applicable. It doesn't really matter if you mention or not. Now coming to what to mention if you really want to mention as best practice, you can mention as per your product model which can be either MSA2052 SAN or MSA2052 SAS. It doesn't really matter what kind of drives you are using.
some examples I have seen as below and one of them product details not mention as well,
defaults {
user_friendly_names yes
polling_interval 10
path_selector "round-robin 0"
path_grouping_policy group_by_prio
prio alua
path_checker tur
rr_min_io_rq 100
flush_on_last_del no
max_fds "max"
rr_weight uniform
failback immediate
no_path_retry 18
queue_without_daemon no
}
device {
vendor "HP"
product "MSA 2050"
path_grouping_policy group_by_prio
uid_attribute "ID_SERIAL"
prio alua
path_selector "round-robin 0"
path_checker tur
hardware_handler "0"
failback immediate
rr_weight uniform
rr_min_io_rq 1
no_path_retry 18
}
Hope this helps!
