Description:
Alternative to SSDs
Violin Intelligent Memory Modules (VIMMs) are the best way to deliver the benefits of flash in the data center. VIMMs function as a hardware-based Flash Translation Layer within the Flash Fabric Architecture (FFA), providing our Flash Storage Platform with garbage collection, wear leveling, and error/fault management. Data is written to and read from VIMMs, which avoid the shortcoming of Solid State Disk (SSD) designs and the limitations of their legacy storage architectures. As a result, Violin is able to deliver the full potential of flash technology at the cost of legacy enterprise disk with our Flash Storage Platform.
Each VIMM includes:
High-performance logic-based flash controller
Management processor
DRAM for metadata
NAND flash for storage
Scalability
VIMMs enable the scalability of large flash arrays. The advantages of our VIMM architecture over simple SSDs are significant:
Integrated garbage collection for sustained write performance
Low latency access to DRAM metadata and flash memory
Safe access and local storage of metadata for fault recovery
Integrated monitoring and management of flash memory health
Distributed ECC correction for maximum bandwidth
Hot swap and redundancy management
vRAID
Violin’s patented flash vRAID technology, designed specifically to enhance VIMM availability, provides full RAID data protection and a fundamentally more efficient and higher performance solution. vRAID guarantees spike-free latency under load by ensuring there aren’t any reads blocked by erases. Notably, the microsecond latency of Violin’s Flash Storage Platform significantly improves metrics such as file read and write, response, and query times.
Availability
VIMMs work in conjunction with vRAID to ensure a very high degree of system availability and data integrity through multiple techniques, including:
Data validation
Data scrubbing: Flash wear leveling
Flash statistics monitoring
The combination of VIMMs and vRAID resolve the issues of flash errors, reliability, and wear to deliver an enterprise-class flash array with a far greater life expectancy than typical HDD arrays. In all the time that Violin Memory has been shipping flash arrays, no customer has worn out a VIMM. There have been component failures, but typical enterprise use has resulted in wear rates of significantly less than 10% per year.
