RACERUNNER

ACCELA, INVICTA

WHIPTAIL’s proprietary operating system, RACERUNNER, is the reason our Flash-based family of products consistently outperforms similar technologies. Explicitly designed for NAND Flash, RACERUNNER sustains high throughput, high IOPS and ultra-low latency, overcoming the write performance and longevity challenges typically associated with multi-level cell (MLC) Flash.

Block Translation Layer (BTL):
· Greatly extends the useful life of MLC media
· Enhances random write performance
· Employs a method of writing that drastically reduces write amplification
· Avoids continuous repacking
· Avoids repeated erasing and writing of blocks
· Reduces the number of times a small random WRITE IO causes Flash erasure
· Significantly increases SSD cell endurance

Block Linearization
· Wear-leveling algorithm commits all writes across the entire array
· Avoids hot spots and premature wear
· Random write workloads are committed in a 100% sequential fashion

Enhanced RAID Capabilities
· Overcome shortcomings of traditional MLC consumer drives
