All-flash storage server
IT industry concentrates on building scalable storage clusters shared by many users while guaranteeing Quality of Service (QoS). Scalability is the crux of the storage clusters because big data enlarges an amount of data needed to be stored and accessed. Guaranteeing QoS is also important because many users share a single storage cluster. Storage vendors (e.g., PureStorage, EMC, SolidFire) and open source projects (e.g., Ceph, OpenStack Swift, Gluster) provide scalable storage clusters.
We are currently focusing on the following topics.
- QoS management among multiple SSDs
- Architecture of scale-out storage server
- Flash-aware storage server
