Pcie to 4 Port U. 2 Nvme Switch Adapter Sff-8643 with Plx8724 Chipset

Product Model:9324-4I
Product Name:4 Port PCIe 3.0 x8 to Internal SFF-8643 NVMe Adapter
Chipset:PLX 8724
Interface Type:4*SFF-8643 Connectors
Support Equipment:4*NVMe SSD or PCIe adapter card
Host Bus Type Type:PCIe 3.0 x8
It is PCI Express x8/16 Gen3 Multi-Host PCI-e switch Card.  It offers Multi-Host PCI Express switching capability that enables users to connect multiple hosts to their respective endpoints via scalable, high-bandwidth, non-blocking interconnection to a wide variety of applications including servers, storage, communications, and graphics platforms.
The LRNV9324-4I employs an enhanced version of PLX's field tested PEXPCIe switch architecture, which allows users to configure the device in legacy single-host mode or multi-host mode with up to six host ports capable of 1+1 (one active & one backup) or N+1 (N active & one backup) host failover. This powerful architectural enhancement enables users to build PCIe based systems to support high-availability, failover, redundant, or clustered systems.
High Performance & Low Packet Latency
 supports packet cut-thru with a maximum latency of 126ns (x16 to x16). This combined with large packet memory, flexible common buffer/FC credit pool and non-blocking internal switch architecture, provides full line rate on all ports for performance-hungry applications such as servers and switch fabrics. The low latency enables applications to achieve high throughput and performance and supports a packet payload size of up to 2048 bytes, enabling the user to achieve even higher throughput.
