The active active PRO FCa has two very fast 4Gb Fibre Channel ports connected to a high performance RAID controller based on a high power RISC storage processor with embedded RAID 6 XOR engine. In the event of a failed controller the active active PRO FCa will continue to operate on the surviving controller. Supporting the latest in RAID protection technology, the PRO FCa supports all standard RAID levels; 0 for striping, 1 for disk mirroring, 5 for efficient balance of drive protection and performance as well as the latest RAID 6 double disk protection for enterprise class requirements.
The two active active 4Gb Fibre Channel ports can work together to increase data throughput (over 900MB/Sec.), MPIO (Multipathing I/O) is a simple and quick method to improve Fibre Channel data path performance with supported operating system such as OS X and others, with MPIO - performance increase with configuration simplicity results in 510 MB/sec data rate per controller. For even higher dual path method, configuring the PRO FCa with two RAID sets and LUN map each RAID set to its own Fibre port will optimize the data path and produce a respectable data rate of over 550MB/sec. per controller. See the graphics to the right for more detail information.
The active active PRO FCa 4Gb Fibre Channel interface is backward compatible with 2Gb infrastructures and will plug and play in existing Fibre Channel networks.
