Prostar 3920 disk array is a high-performance storage product based on open system design and the latest design concept. The product has a modular design, supports hot-swappable redundant RAID controllers, port bypass and redundant environmental monitoring circuits, has a battery-protected mirrored high-speed write cache, large power supplies and cooling systems. Support multiple target IDs, dual internal independent channels simultaneously connect all hard drives to support automatic error switching and recovery. LUN masking, high-speed cache mirroring and ECC memory maximize data integrity and reliability. SANtricity storage management software allows users to spend very low management costs to achieve unified management. It can be flexibly managed anywhere, and only one interface is needed to manage the entire PS series storage platform, so that the system can be upgraded seamlessly. The management software integrates the functions of partitioning and replication, and through the configuration file, it can flexibly realize functions such as increasing capacity, performance adjustment, storage merging, and data replication.
The ProStar 3920 is a modular, 3U rack‑mount storage array designed for SAN and cluster environments. Each chassis holds 16 drives and can be expanded up to seven chassis (112 drives) with capacities up to 33.6 TB over fiber or 84 TB with SAS drives. It offers high performance with up to 120 k IOPS, 1.5 GB/s sequential read and 850 MB/s write, and supports RAID 0, 1, 0+1, 3 and 5.
Management is handled by the SANtricity software, which provides unified administration, online capacity expansion, RAID level migration, snapshots, and remote mirroring. The system is compatible with Windows 2000/2003, Linux, Solaris, HP‑UX and other operating systems, and connects via 4 Gbps Fibre Channel or 2 Gbps/1 Gbps FC links. This manual is written in Chinese.
