I'd like to build a superfast Thunderbolt DAS for use with the new MacPro. The Idea is to build a computer from either a TB2-equipped motherboard like the ASUS Z87-DELUXE/ QUAD or another motherboard using a thunderbolt expansion card like the ASUS Thunder EXII, and stuff it full of RAM and perhaps an SSD RAID. The Idea is that this would allow me to create a >30GB RAM-disk that could completely saturate TB2, providing a bootable 20Gbps drive with access times in the millisecond-range for the new MacPro. the ramdisk would be continously backed up to an SSD and the whole thing protected by a UPS. Possibly, the same computer could also act as a host for a secondary standard SSD-raid also exposed via thunderbolt, either through the same thunderbolt port or using the second thunderbolt port (the ASUS Z87-DELUXE/ QUAD has two TB2-ports). A few GB of RAM could possibly be used as a cache to speed up this RAID. I'm open to selection of OS for the DAS: it could be Linux, Windows or OSX depending on where the best software and tools for making this work exist. There are a number of hurdles: first I'm not sure if the TB2 controller on a computer motherboard could be configured to take the role of TB-disk. One idea is to install OSX and use the thunderbolt networking feature to publish the RAM-disk as a network drive. (I'm not sure this would make the drive bootable and there would probably be other drawbacks too. ) Any thoughts on the feasability of setting upa TB2-equipped computer as a DAS? Any ideas on tools and methods that could be employed to make this work?
