Hello All,
I have a new storage build with following spec below ,
The storage serve as cifs nas and iscsi for XEN 3 hosts hypervisors.
The pool is built with 2x8 Disks per each vdev , each vdev is Raid-Z2
Pool where divided to 3 zvol's 4TB each for iscsi Xen network , and one Dataset of 18TB allocated for storage NAS based cifs usage ,4 ssd's where assign globally to cache 2x mirror for metadata(log/zil),2x in strip for read (l2arc).
All system is currently up and running , but i would like to tune the 10G network card to be optimized , i read few posts about 10G network tuning , i picked two suggestion for tuning and i would like your opinion which is most suitable to given scenario spec?
Thanks
