Afternoon,
Apologies if you feel this is a duplicated question, I have looked around and done huge amounts of reading but wanted to just ask the question for my particular setup. This is a new field for me as most my clients/previous work, etc. has been completed using SAN/NAS kit brought for huge sums of money (mainly NetApp).
Sadly I do not have huge sums of money to buy one of these what I do have a machine which is your basic home hardware desktop no Server grade kit except for a Network card (Intel dual NIC Gigabit which I'm hoping to Bond). It has a RAID controller for the built-in SATA ports which will be hosting 2x2Tb SATA drives.
This will be for a Lab environment so not critical data however would prefer it not to loose data continuously as I might not get too much work done in my Lab. It will be used for hosting XenServer VM's via an ISCSI target so I'm guessing corruption would mean death to any VHD's almost instantly.
So what I already know is:
Do not use hardware RAID and ZFS together.
Do not use ZFS without ECC Ram due to almost certain risk of corruption.
What I'm unsure of is:
What is FreeNAS using if its not ZFS, in other words what file type does its ISCSI LUN use?
If I'm not using ZFS should I RAID 1 my drives using the hardware RAID and create the LUNS on just the one present drive which would still be protected by the hardware RAID?
As the drives are only 7,200 SATA drives should I forget about redundancy as its a Lab environment and just RAID them in Striped 0 to gain a speed increase and if it goes bad then just rebuild my lab?
Thanks in advance,
Charles
