hello,
i have an 3u enclosure with 16 hot-swap drivebays.
i polutated 14 of them with 2tb sata disks and 2 polulated with 120gb ssd disks for zil.
(core i3 cpu @ 2.8 ghz, and 32gb ecc memory)
all are connected to an lsi 9211 8i sas controller with an sas expander board (also lsi).
it works great and freenas sees all disks.
now i made a raidz2 vdev on it with 1 hot spare. thinking this would be a great setup. 14 data disks. 1 spare and 2 parity makes 11 disks of 2tb netto storage.
now i read on several posts not to add more than 10 disks in a vdev.... oooopssss...
so i read all of you recommend raid 10 or a striped mirror.
so i want to put 2 disks in a mirror and do that 7 times. so i will get a stripe of 7 mirrors. (14 disks). is this a recommended setup?
or should i create to stripes of mirrors (for example 1 stripe of 3 mirrors and 1 stripe of 4 mirrors)
i use the storage as iscsi for vmware and afp/nfs/cifs storage for video/data
