Apart from the fact that even devices with multiple interfaces are generally designed to only allow one to be active at a time, if somehow you managed to connect two computers at the same time then it is not capable of arbitrating simultaneous access by two computers, if this happened you would get corruption. So there are no such products.
If you want to have two or more computers access shared RAID storage then the following are the only options -
- Use a NAS (Network Attached Storage), this is effectively a RAID box with a computer inside it acting as a file server, each computer would connect to it over the network via a suitable protocol which could be AFP, SMB, NFS, or iSCSI
- Connect it to a single computer and share it to other computers, the external RAID box would then be a 'DAS' (Direct Attached Storage) type device
- Use a SAN (Storage Area Network), this is a high-end type of RAID system which is designed to connect to a SAN and then multiple computers also connect to the SAN. Each computer can access their own private area on the RAID system but if you want them to access the same area then you need a SAN metadata controller, this is what Apple's Xsan software does for example
Note: Drobo do mainly DAS type devices, but also do NAS type devices or have a way of adding NAS capabilities to one of their DAS type boxes. They are not regarded as a leading NAS supplier, leading brands of NAS would be QNAP, Synology and NetGear/ReadyNAS
Note: iSCSI is a way of doing a SAN over a normal Ethernet network instead of FDDI, you may still need a metadata controller.
