Post FreeNAS as iSCSI for ESXi 4.1 working
I can connect to FreeNAS iSCSI with ESXi4.0.
You have to commit the entire drive to be iSCSI. So can't share the same once drive between a CIFS share and iSCSI.
You can add multiple drive and make the other drives CIFS, FTP, uPNP, etc

It might be hard to see but the first two drives are set up as RAID1 for CIFS and the second two drives are set up as RAID1 for iSCSI.

Thanks for the info newmember, can you clarify, is FreeNAS running on a standalone host or did you follow the instructions Dave has posted on using passthru on SATA/SCSI drives to run FreeNAS as a VM from within ESXi?

I put FreeNAS as the host OS. I didn't go with the VM install, to me it seemed that added a layer of management I didn't need.

If you were to use VMware I think you you would create a virtual disk for FreeNAS to run on, and then create a seperate virtual disk that you could mount, then use that entire second disk for iSCSI. I guess you add 3 virtual disks and configure them as RAID5. I would not see the point if all those virtual disks were on the same HDD.

For me I installed FreeNAS on a 4G Patriot USB key. Then added two disks for RAID1 for CIFS, then added two disks for RAID1 for iSCSI. I used a Patriot key because it has a higher read access then most USB sticks.

Does this help?

I'm doing something similar with Freenas myself.

I have Freenas running an old Winfast socket 939 board with an AMD 3800X2 processor & 4 gigs of ram. There are 6 250 gig Western Digital PATA drives, 4 on the motherboard header & 2 on a Promise PCI IDE card.

I boot the system off a USB key.

I"m using ZFS on the 6 drives to give me a total of 1.36Tb. Even though the drives are connected in a less-than-optimal way, I a extremely pleased with the performance.

What's nice about using ZFS is that I can actually carve up the 1.3Tb as I want, there's no need to dedicate the whole dire to either CIFS shares or iscsi. In my case I have a 350Gb device, called an "extent" presented to my ESXi box over iscsi. Think of the extent as something like a virtual disk, the disk space is allocated, so the whole amount is in use as far as the filer is concerned. To ZFS though the extent is just another file so I still have another 800gigs I can use for shares. For grins I also have an NFS share on the filer that the ESXi box also mounts.

I originally ran the i386 flavor but switched over to the 64bit build when I freed up 4 gigs of ram from another application. The performance difference between the 2 was simply astounding. If nothing else ZFS loves the ram!

I was converting a disk image and thought I would capture the freenas speeds.
Intel Pro 1000 card
LINKSYS Gigabit 5-Port Workgroup Switch
Transfer was from my laptop.

Hello,

So how did you wind up setting your rig up?

Did you use one of the official builds? 32 or 64 bit? ZFS?

Happy with it?

I have been running this for a few months and its been great.
I run the kids movies from it. I run iSCSI for my vmware ESXi servers. I run it for my backups. I use it sync backup my laptop. I about to set up NFS so that I can do diskless booting on the kids computers.

The one thing I have to spend more time with is the permissions. I want to reduce the access to certain content. Currently the kids can only read the movie files, while I have read/write/delete access.

Anyone know if FreeNAS will work with a full version of 3.5?

You should be fine with NFS or iSCSI.

I followed the guid in ESXi 4.1 and can only say:
THANK YOU!

it worked great, only took me 10 minutes of config time, and is working like a charm!

Thank you very much
