iscsi sata idea

Anyone know of a small device that could be made to run linux and if linux could make it do the following?

flip a sata controller to make the device act like a drive instead of a host

then use iscsi to connect to a lun on an iscsi array

my idea is to be able to present an iscsi lun to a DVR.

anyone know of a device and how to do this in linux?

If the chipset is able (which I've e-mailed about) I'm thinking of using this »www.solid-run.com/cubox

I think it'd be very cool to have my DVR using an iscsi lun instead of an esata drive.

No need for a "controller". iSCSI is all software based unless you get a NIC card that it is offloaded to.

If »www.freenas.org/ supports your hardware, you’re almost done.

Um ya try mounting an iscsi lun on a Directv DVR

the idea would be to make a simple device that would connect via esata to a device that can't do iscsi.

I have a iscsi array what I'm looking to do is connect a device that can't do iscsi to an iscsi array.

Ideally I'd have some small low power device that would be connected to the esata port of my DVR and to my network

Then instead of having a solo esata drive connected to my DVR I'd have a whole iscsi array that would be running raid 5

What model DirecTV DVR? Newer model or older TiVO?

HR20
currently with a 2TB seagate constellation drive in an esata enclosure

I'd hope the "little" device would end up being able to draw less power than a harddrive so I'd gain the benefit of moving(mostly) the power load to my iscsi array. (as well as gain the reliability of raid 5 for my DVR recordings)

Though if I can find a device that can do this I'd also need to add more storage to my array as I don't have 2tb availalbe to issue as another lun and I'd want to clone the 2tb esata to a lun

I think it'd be very cool to use my iscsi array to replace my DVR's drive (If this ends up working then I think I'd also remove the harddrive from inside the HR20 after all its just spinning using up power)

So the idea would be the device lets call it a iscsi esata bridge
would be an iscsi initiator with a sata controller flipped to act like a sata drive.

So do you get the idea I'm going for now?

So I guess no one here knows how to make such a device.

I'm sure its possible, maybe not with a standard sata controller, maybe it'd have to be some custom board with some chips off a sata drive.

Looks like I might finally be making some progress

Ok so using maybe more correct terms

I'm trying to make a sata target and iscsi initiator in one box

So the iscsi initiator would connect to an iscsi target (my iscsi array)
then it'd pass the iscsi lun out via the sata target and the sata initiator (IE the DVR) would then see the iscsi lun as a sata target.

its starting to look do able, seems someone has made a driver to make a marvell controller switch to target mode instead of initiator mode, so now if the box I'm looking at using uses that controller it'll just be a matter of figuring out the linux commands to make it happen
