External PCIe 3.0 expansion chassis Single slot


With Netstor's NA221A-G3, add-on cards can be completely removed from the server chassis. The included PCIe card NP963AG3-H provides a fast connection to the expansion housing in the host. Thanks to the PCIe Gen3 x4 host interface, the NA221 has a bandwidth of 32 Gbps.

The tandem offers the option to alternately use expensive cards on several computers without having to unscrew them each time. In addition, the system allows full height expansion cards to be operated in server with small enclosures.

The housing effectively cools down the installed card during operation by means of two powerful fans. A 65 watt power supply unit provides the power supply.

The NA221A-G3 was developed for all operating system platforms. It does not require a driver itself. Thus the Netstor unit works with all computers under Windows, Linux and MacOS.
