High Availability Models

AccelStor’s proprietary symmetric active-active shared-nothing design ensures both nodes operate simultaneously with no single node failure and delivers 99.9999% reliability. Thanks to FlexiRemap’s built-in 2(N+1) proprietary algorithm, NeoSapphire AFA can sustain the service when two SSDs fail at the same time or even in the event of a controller or flash drive failure. The nodes execute synchronous replication with each other via a high-speed interface. Even under the data protection level of double copies, the storage architecture can still achieve ultra-low latency of less than 1 millisecond, ensuring the lowest RTO (Recovery Time Objective). And with the “3+2+5” data protection strategy, AccelStor’s NeoSapphire AFA fully protects your critical data.

AccelStor’s proprietary FlexiRemap® technology can maximize each SSD utilization by distributing data evenly to the underlying SSDs after re-arranging the writing order to balance the SSD load. NeoSapphire AFA can fully utilize all flash module bandwidths, ensuring true storage performance with 60-110K IOPS sustained and meeting high-performance requirements of I/O intensive applications, such as artificial intelligence, virtualization, database, and media production.

AccelStor’s NeoSapphire High Availability AFA offers a wide range of storage options in 4U to 12U space-saving form factors and can provide a usable physical capacity of up to 228TB, which saves data centre space while ensuring optimum and flexible resources management for enterprises.

Unlike conventional RAID technology, AccelStor's proprietary algorithm FlexiRemap® can activate its data protection mechanism if one SSD fails, avoiding 2 SSD failures in the same group and eliminating data loss risk. With the support of snapshot, Free Clone and snapshot backup features, NeoSapphire High Availability AFAs can execute data restoration in case of accidental loss.

AccelStor's NeoSapphire AFA also supports remote replication for disaster recovery by establishing a transmission channel between the user's production and disaster recovery centres.

With AccelStor's proprietary algorithm, NeoSapphire HA AFA unleashes excellent storage performance and increases SSD lifespan by 40-60%, which significantly decreases the TCO of the storage system. The system supports inline deduplication and compression, background deduplication and compressions in off-peak hours to increase efficiency.

Besides, the patented algorithm maximizes SSD performance to ensure the minimum cost per IO. With an excellent price/IOPS ratio, NeoSapphire AFA ranks No.1 in the SPC-1 Price-Performance Rankings.

AccelStor's NeoSapphire AFA can support Vmware, OpenStack and Kubernetes through driver plug-ins. It also supports the external management of the third-party platform based on the standard RESTful API, meeting various customer needs.
