HighPoint have further expanded their range of RocketRAID RAID controllers with the new RocketRAID 3522; an enterprise level PCI-E x8 add-in card with two external mini-SAS connectors running off Intel's IOP 341 I/O Processor.
Enterprise level data protection is offered in the RocketRAID 3522 with RAID 5 (XOR) and RAID 6 (P+Q). By offering 8KB of NVRAM redundant RAID arrays can avoid degraded and out of sync RAID arrays by avoiding WRITE holes due to unexpected power failures. Logs are stored in the NVRAM to let users check their RAID arrays for consistency. To prevent data loss the RocketRAID 3522 offers an optional BBU (battery back up unit) to store unwritten data for up to 72 hours when there is system power failures.
