Memblaze launches PBlaze5 920 series enterprise-class NVMe SSD, greatly improving user experience.

March 16^th, 2020 Beijing Memblaze Technology Co., Ltd (Memblaze) announced the launch of the PBlaze5 920 series enterprise-class NVMe SSD, greatly improving the user experience. The PBlaze5 920 series NVMe SSD uses 96 layers of 3D eTLC NAND and has two forms of U.2 interface 2.5 inch hard disk and half height and half length card, with a maximum capacity of 7.68TB. The PBlaze5 920 series includes PBlaze 5 D920, PBlaze 5 C920, PBlaze 5 D926 and PBlaze5 C926 4 SKUs.

The PBlaze5 920 series NVMe SSD provides up to 5.9 GB/s sequential read bandwidth and 970,000 read IOPS performance with read/write latency as low as 90/12 μ s. With excellent and stable performance, perfect data protection mechanism, good system compatibility, use experience and rich enterprise-class features, the PBlaze5 920 series NVMe SSD can help enterprises to build high-speed, highly reliable, flexible and easy-to-use storage solutions for their critical business applications. Excellent QoS and performance consistency, greatly improving user experience.

The PBlaze5 920 series NVMe SSD can realize smooth transition in 4K random writing, from empty disk to steady state, and in the state of mutual conversion between sequential writing and random writing, thus fully ensuring stable equipment performance without large jitter. At the same time, the PBlaze5 920 series NVMe SSD also greatly improves the efficiency of GC reading, thus greatly improving the overall efficiency of GC execution.

The excellent QoS consistency of the PBlaze5 920 series helps customers to avoid the risk of poor user experience and even business interrupt caused by excessive processing time of SSD some IO due to the surge of business access. At the same time, good I/O QoS provides reliable guarantee for cloud computing and overall QoS improvement of storage system.

Quota by Namespace to ensure business IO access priority

As the deployment of many different types of applications on a single large-capacity NVMe device is increasing day by day, the new feature of Quota by Namespace is integrated into the series of PBlaze5 920 products launched by Memblaze, which is also one of the few enterprise SSD products in the industry with this capability.

Quota by Namespace is to implement Quota operation on the Namespace of NVMe SSD, and select the appropriate Namespace according to application priority, etc. to realize optimization and expansion of application scenarios. By creating different namespaces on Memblaze PBlaze5 920 series and imposing Quota restrict on namespaces of tasks with lower priority, namespaces of high priority tasks can be guaranteed to enjoy more IO resources.

Online Firmware Upgrade to Ensure Continuous Business Continuity

Traditional firmware upgrade operation requires cold restart of the server and restart of each module of the business system, which is tedious and prone to errors. Memblaze PBlaze5 920 series NVMe SSD supports online firmware upgrade. even if there is IO in the business, the firmware upgrade can be completed without restarting the server, which ensures the continuity of storage system services, greatly simplifies the operation and maintenance links, and reduces the difficulty and cost of it system operation and maintenance.

Variable Sector Size Management, Flexible End-to-End Data Protection Scheme

Sector Size (Variable Sector Size (VSS) can save user data and metadata of the data at the same time. The Memblaze PBlaze5 920 series supports 512 bytes, 4096 bytes, 512+8 bytes, 4096+8 bytes and 4096+64 bytes Sector Size, i.e. the service application issues an I/o and can carry 8 bytes or 64 bytes of metadata. VSS technology can further ensure the high data reliability requirements of storage systems and distributed file systems on the premise of ensuring high consistent performance.
