Also, one feature that'd be AWESOME would be support for making a RAM disk out of a chunk of system memory.

I mean, Sun and HP both have (eight-way quad opteron) boxes with up to 64 DDR2 slots. MetaRAM has 8GB DDR2 RAM sticks, and they're coming out with 16GB ones (that they claim is compatible with such opteron chipsets), so that is potentially 1TB of system RAM!!!

This should enable ridiculous (ludicrous?) SAN/NAS performance. Some customers would like to be able to carve out even a dozen GB of RAM to use as scratch-disk or on some really crazy database application.

This RAM disk would help us to tweak system performance maximally and to help us prepare for SSDs.

And, it'd enable us to "legitimately" claim equally ridiculous performance specs in our marketing .

Eventually, it'd be cool to have the RAM disks replicated via iSCSI failover or something like that to make it partially sane to use even in production environments.

So... Ram disk support?
