NVMe chipsets target data centre SSD requirements

Chipsets launched by Marvell, will accelerate the time to market for application-optimised data centre SSD implementations, says the company. The Marvell 88NR2241 NVMe switch and 88SS1098 and 88SS1088 PCIe Gen3x4 NVMe SSD controllers address current and emerging workload storage requirements, spanning capacity, latency, performance, power and cost for cloud and enterprise workloads. 

The proliferation of cloud services and new technologies, such as artificial intelligence (AI) and machine learning (ML), is driving various workloads in the data centere, says Marvell. These workloads can have differing storage requirements that emerging SSD form factors are targeted to address. Marvell has developed the NVMe chipsets to be capable of powering the larger enterprise data storage form factors (EDSFF), next generation small form factors (NGSFF) and various customised form factors. 

The Marvell 88NR2241 intelligent NVMe switch allows data centres to aggregate and manage resources between multiple NVMe SSD controllers and workload-offload accelerators. The switch enhances multi-tenant, virtualised cloud and enterprise data centre environments by offering predictable storage performance using integrated virtual functions. The Marvell 88NR2241 can provide up to 6.4Gbyte per second of throughput and up to 1.6M random input output per second (IOPS). It enables, says Marvell, the industry’s most flexible SSD architecture for optimal workload efficiencies around power, performance and cost.

The 88SS1098 and 88SS1088 are Marvell’s latest PCIe Gen3x4 NVMe SSD controllers supporting single and dual port functionality, the NVMe 1.3 standard, and open channel architectures. Both controllers are powered by Marvell’s fourth generation of NANDEdge LDPC error correction technology, which provides support for the latest 3D NAND TLC and QLC technologies and maintains latency and performance consistency. The controllers leverage Marvell’s SoC processor architectures to enable up to 3.6Gbyte per second of throughput and up to 800k of random read IOPS, supporting up to 16 NAND channels and 16Gbyte DRAM.

The chipsets can support up to industry-leading 32Tbyte capacities, says Marvell, to support a range of cloud and enterprise SSD solutions – including M.2, NGSFF, U.2, PCIe add-in-cards, EDSFF and custom-built.
