In September, a media storage system integrator once again purchased EB-LINK's PCI-EX16 to M.2 four-port expansion card for the single-machine capacity upgrade of the local high-definition video archiving project. This batch of goods was shipped as scheduled after card-by-card full load testing.

A rigid need to connect four disks to one slot

The archive server chassis of this project only has the last full-length x16 slot available. It was originally planned to connect an external disk array, but the budget and the load-bearing capacity of the computer room did not allow it. After switching to a four-port solution with a double-sided layout, a single card can be connected to four NVMe disks to meet the high-speed reading of near-line materials. The network port is reserved for the upload link, and the overall cost is significantly reduced. When comparing models, customers choose between standard double-sided version andPCI-EX16 to M.2 four-port expansion card (double-sided version)After repeated evaluations, the final decision was made based on the disk length and heat dissipation space.

Double-sided layout and heat dissipation are the focus of acceptance

Four disks are concentrated on one card, and the double-sided arrangement requires higher air ducts. The technical team recommends that customers give priority to solutions with heat sinksPCI-EX16 to M.2 four-port expansion card (double-sided ultimate version), and a first-level auxiliary air inlet was added to the front of the chassis, and the measured temperature of the fully loaded bay was controlled within 70°C.

There will be supporting support after delivery

This batch of goods comes with card-by-card test records and fixed stud spare parts. The support team synchronously reviewed the channel split settings of the customer's motherboard to ensure that the four disks are independently identified as x4. The same slot system can be used for subsequent expansion.
