As I understand it, in a traditional RAID 5 setup adding new disks to the pool
provides more overall I/O as the load is spread out across multiple disks.
What exactly is this relationship in a RAID-Z setup? What should one expect in

Hello,
I'm sure this question has been asked many times already, but I couldn't
find the answer myself. Anyway I have a laptop with 2 identical hard disks
250Gb each, I'm currently using Linux on RAID0 which gave me ~500Gb..
I'm planning to switch to FreeBSD but I want to know before I do, what c
If you want any kind of data guarantee, you need to go for a mirrored
pool. If you don't want a data guarantee, you can create a single pool
(non-mirrored) of the two devs which will give you 500Gb. The key is
in the 'zpool create' command
zpool create twofifty mirror disk1 disk2
zpool crea
Since all my data are on this PC and I have many externals HDDs (around 3Tb)
I think I'm gonna go with Mirrored setup, protect my data.. but out of
curiosity, if someday I decide I want 500Gb, can mirrored setup be switched
to single devs on the fly or a complete array rebuild is necessary?

Uhhh - for an unmanaged server you can use ESXi for free. Identical
server functionality, just requires licenses if you need multiserver
features (ie vMotion)

Simply put ESXi is exactly the same local feature set as ESX server.
So you get all of the useful stuff like transparent memory page
sharing (memory deduplication), virtual switches with VLAN tagging,
and high performance storage I/O. For free. As many copies as you like.
But... You will ne
