-
- Multi-Core RAID - the new generation of RAID Engine completed re-designed infrastructure, by this technology evolution we got 0.96 core scaling factor for RAID IOPS which fully unlock the value of FLASH media. It works in symmetric Active/Active mode.
- Multi-Core Cache - the system persistent DRAM Cache, which mirror the write data to peer with very large scale caching ability, e.g. 5 million IOPS. It is also symmetric Active/Active. And optimized for SSD and the hybrid drives.
- Multi-Core FAST Cache, reorders the IO flow to put hot data into SSD media to improve system IOPS and response time. It presents symmetric Active/Active.
Requires:
- 1 years + working experience in complicated system, e.g. critical telecom product, OS, networking, storage, file system etc.
- Experiences in professional system-level software architecture and development experience
- programming experience
- Strong Linux/Windows kernel programming skills
- Knowledge and expertise in one or more of the following areas is great plus: file systems, storage protocols (NFSv3, v4 and v41 pNFS, CIFS, iSCSI), storage technologies (SAN, NAS, RAID, OSD, snapshot, replication), networking, device drivers, clustering
