Kioxia SSD With Flexible Data Placement Demonstrates Improvements In Lifespan, Performance

KUALA LUMPUR, Oct 16 (Bernama) -- Kioxia Corporation is showcasing and demonstrating the benefits of a KIOXIA XD Series SSD equipped with Flexible Data Placement (FDP) functionality running the RocksDB database at the 2024 OCP Global Summit, taking place from Oct 15 to 17 in San Jose, United States of America.

The RocksDB database excels in high-performance searches through vast amounts of data and managing history data, and is widely used in generative artificial intelligence (GenAI) and cloud applications.

FDP is a feature defined in the NVM Express base specification (TP4161) that allows flexible control of data placement within a solid-state drive (SSD), according to a statement.

By appropriately managing data placement within the SSD, while minimising changes to host software and device drivers, FDP optimisation can enhance performance and extend the lifespan of the SSD.

SSDs follow instructions from host software and device drivers for data storage and erasure. As this process is repeated, data reallocation may occur within the SSD, potentially leading to reduced access speed and unnecessary consumption of flash memory write cycles, especially when data reallocation occurs frequently.

Leveraging FDP can help mitigate potential data reallocation, maximising the performance and lifespan of the SSD.

The demonstration at OCP Global Summit shows FDP functionality in a KIOXIA XD Series Data Center NVMe SSD and a Kioxia developed plugin, a small programme that extends functionality in an application enabling FDP capability, and tested with RocksDB.

Thorough testing and evaluation have resulted in approximately three times the lifespan improvement and approximately 1.8 times the performance for the RocksDB application in an FDP-enabled system, compared to a traditional system utilising conventional SSDs and file system.
