Case Study: RAID Controller Cards
Everspin MRAM was the memory selected for the journal memory on LSI Corporation's (Now Avago Technologies) RAID controller cards featuring 6Gb/s and 12Gb/s SAS storage connectivity. Everspin MRAM performs the write journal or data log function in their RAID disk arrays.
The MRAM captures transaction information in real-time so that data can be recovered should a system failure occur. Data logs written to MRAM also capture system conditions and status for remote diagnostics and repair. MRAM chips were also included on LSI Corporation's reference designs for third party RAID cards and RAID-on-Motherboard (ROMB) solutions.
MRAM in RAID Controller Applications
Everspin MRAM is fast write, able to store data in real-time and is non-volatile with 20 years retention over the operating temperature range. External batteries or capacitors are not required.
Case Study: RAID-on-Chip Journal Memory
As well as for its fast-write without requiring load leveling or ECC overhead, Dell selected MRAM because MRAM non-volatility supports enhanced data center fault recovery, reduced system downtime and lower total cost of ownership. In addition, the fast write times of MRAM without load leveling or ECC overhead simplifies system design.
MRAM in RAID Servers
MRAM’s performance, high endurance and non-volatility allows Dell to provide industry leading RAID servers with enhanced data center fault recovery, reduced system downtime and lower total cost of ownership.
