PBlaze6 6641 Series advanced enterprise SSD optimized for PCIe4.0 server that delivers a massive 150% improvement in energy efficiency over the previous generation PCIe 3.0 PBlaze5 920, dramatically reducing power consumption of data center. PBlaze6 6641 Series offers capacity from 1.6TB to 7.68TB, all capacities come in 2.5-inch U.2 form factor.
PBlaze6 6641 series supports dual-port and allows access via two ports simultaneously, which solves the single-path failure, ensures continuous data access andmeets enterprise high availability requirement. Suitable for multi-path highly available storage system architecture and all-flash arrays. With no impact on enterprise business-critical continuity, minimising QoS impact.
The PBlaze6 6641 Series offer 7.68TB capacity up to 1DWPD over 5 years for eadintensive workloads; the PBlaze6 6647 Series offer 6.4TB capacity up to 3 DWPD over 5 years for mixed read-write workloads, all capacity support 2.5-inch U.2 form factors.
The PBlaze6 6641 series has a built-in optimised IO scheduling mechanism that ensures QoS and performance consistency of IO access, guaranteeing the high and consistent performance required by enterprise-class applications. PBlaze6 6541 series combined performance of the dual-port PBlaze6 6641 series is essentially equivalent to that of the single-port PBlaze6 6541 series, meeting the high-performance requirements of enterprise-level users.
PBlaze6 6641 series support richer enterprise features: Firmware Upgrade Without Reset, Telemetry, Persistent Event Log, Latency Statistics & High Latency Logging, NVMe-MI for Out-of- Band Management, Trim etc. to meet different business needs.
