RAID storage
High reliability and performance data storage solutions from Infineon
At Infineon, we understand the need for high reliability, high availability, and performance required for a RAID. RAID is a technique that combines multiple physical disks into one or more logical units for the purpose of making it a high-density data storage with data redundancy, data integrity, performance improvement, or all of these. RAID controller cards are the data storage devices used to manage hard disk drives or solid-state drives.
Our non-volatile SRAM (nvSRAM) and Ferroelectric RAM (F-RAM) are commonly used in these RAID card applications to keep track of the data packets while it transfers between the host and storage system, otherwise known as write journaling. If the system loses power while writing, the journal information is read back at next power cycle to identify any data that was not yet written. Parallel nvSRAM and serial Quad SPI
F-RAMs are preferred over other non-volatile memories due to their fast write speeds, high endurance and ability to capture data instantly on power loss without the use of any power backup.
High reliability for preservation of critical data without compromising performance
- Eliminates the need for back-up batteries or super capacitors
- Provides unlimited (nonvolatile) write cycles at the bus speed
- Instantly captures data on power loss
