PBlaze5 920 series is implemented with patent data protection technology, including LDPC error correction, AES-256bit Data Encryption, Full Data Path Protection, T10 PI End-to-End Data Protection(DIF/DIX), Enhanced Power Failure Protection, from device to link path layer, fully protect enterprise data in a safe and reliable storage environment.
To satisfy continuity of enterprise critical business and reduce the complexity of large-scale SSD upgrade operations in data center, PBlaze5 920 series NVMe SSD supports feature firmware upgrade without reset, enabling complete firmware upgrade without stopping businesses or shutting down systems.
PBlaze5 920 series supports up to 32 namespaces, share capacity and performance on single drive for multi-application deployment scenario. Each namespace has a different AES-256 key to encrypt data, to avoid new user access to old data and provide data access isolation. To ensure QoS of critical business, PBlaze5 920 series provides feature Quota by Namespace to set performance limitation for non-critical application deployed in different namespaces.
The Variable Sector Size (VSS) transfers user data with metadata. PBlaze5 920 supports 512, 520, 4096, 4104, and 4160 bytes Variable Sector Size, which means an I/Os from service application carry 8 bytes or 64 bytes of metadata simultaneously. On the premise of ensuring high consistent performance, VSS further guarantees high data reliability requirements for storage systems and distributed file systems.
To meet the high security and high-performance requirements of cloud computing, the PBlaze5 920 series supports enterprise-class TRIM function to ensure that trimmed old data will not be accessed by new users, while, significantly improves performance and endurance. Special designed TRIM mechanism has minimal impact on the business. The speed of TRIM is up to 8TB/s. Combining with applications to realize flexible TRIM strategy.
The PBlaze5 920 series supports dual-port function which solving the single-path failure problem. The two ports can be accessed simultaneously, which ensures the continuity of data access and minimizes the impact on QoS of critical service. PBlaze5 920 series is applicable to high-availability storage system and all-flash arrays with multi-controller, multi-path architecture. The PBlaze5 920 series also supports NVMe reservation function, which can be used for quorum disks in storage system.
