Huawei OceanStor mid-range storage systems are comprised of 10 models, including 5 hybrid systems and 5 all flash systems. The hybrid systems are the 5300, 5500, 5600, 5800 and 6800 V5 systems. The all-flash systems are the 5300F, 5500F, 5600F, 5800F and 6800F V5. These are mid-range systems with extensive features and capabilities supporting both block and file access. Huawei has delivered a succession of storage systems in the high-end, mid-range and entry levels. These systems represent a succession to their previous V3 models of these same products.
All systems support a scale-out architecture with up to 4 controller pairs, (8 controllers) connected via 10 Gb Ethernet. Storage devices in enclosures are connected with 12 Gb/s SAS. SSDs and HDDs are supported in any combination.
Connectivity for block access is through Fibre Channel, iSCSI, and FCoE. File access is over Ethernet using CIFS and NFS protocols. Block and file support is an integral capability, not requiring an additional controller function.
Third party storage can be virtualized behind the OceanStor system allowing centralized management of storage resources and migration of volumes for load balancing, retiring external storage systems, and conversion from thickly provisioned volumes to thin.
Advanced features of the OceanStor system include compression and deduplication, cache partitioning, quality of service controls, secure erase, dynamic tiering, and caching with SSDs. Snapshots, asynchronous and synchronous remote replication, LUN copies, and consistency groups are also included.
