Peripheral Component Interconnect Express (PCIe) interfaces present users with a myriad of advantages, such as: increased performance, low latency, and increased throughput. Although this high-speed serial connection is a form of SSD, it has unique aspects that play a part in testing, such as: - The interface to the system motherboard is through a different technology
- Higher power consumption
- Differing airflow requirements dependent on their form factor
Due to the increased popularity of PCIe as a storage solution, it is becoming increasingly vital for manufacturers and OEMs to validate the performance of their PCIe through impartial, third-party test solutions. Existing SSD testing methodologies won’t suffice for PCIe testing. The unique differences of PCIe call for the use of testing systems and processes that are tailored to their specific needs. The challenges to PCIe testing mainly pertain to the areas of mechanical, electrical, and software. The following testing requirements apply: - The use of Environmental and Burn-in PCIe testing systems to simulate device wear
- Isolation of the support electronics is mandatory
- The ability to remove independent devices without interrupting other Devices Under Test (DUT)
Investing in Optimal PCIe Testing Services Despite the above-mentioned challenges, it is extremely important for manufacturers and OEMs to ensure breakthrough performance via PCIe testing. This can only be achieved through highly accurate test systems that carry out comprehensive tests in a variety of simulated conditions. For this purpose, manufacturers and OEMs need to engage the services of a reputable test solution provider or test system manufacturer that can provide a customized solution tailored to the specifications of your product. Here are some of the things to look for in effective PCIe testing systems: - The test systems should integrate features such as customized airflow so as to ensure uniform cooling across individual PCIe form factors.
- A turnkey solution that comprises of a complete package of hardware and software as well as all encompassing test scripts to carry out end-to-end testing
- The chosen testing provider or system manufacturer should have a variety of test systems that cover environmental, burn-in, and performance testing
- A solution that features end-to-end Gen 3.0 connectivity and the technology to provide the precise thermal/humidity environment without harming the test equipment is essential
In this era of cloud computing, PCIe has gained great importance as it is the proven solution used in applications such as large-scale distributed web caches, VDIs and OLTP databases. As modern datacenters demonstrate a rising demand for PCIe, it has become important for manufacturers and OEMs to invest in a comprehensive, end-to-end solution that will give their products a definitive edge over the competition.
