About the mA-3A01
The mA-3A01 is an AXIe-based mass storage module that supports up to four NVMe
(Non-Volatile Memory Express) Solid State Drives (SSDs). The mA-3A01 supports both
large file streaming data and mass storage on the same solid state drives.
The mA-3A01 is designed to provide storage capability to an AXIe chassis (mA-1302 or
mA-1305). mA-3A01 hardware configuration options allow for up to four 3.2 TB enterprise
grade Micron U.2 2.5” form factor SSDs (12.8 TB).
The high write durability of the SSDs make them ideal for streaming data, while the large
storage capacity also makes them useful for mass data storage. When used in
combination with the mA-6806 VST or mA-6A30 Downconverter, and the mA-3011
Embedded Host Controller, the mA-3A01 supports streaming large file storage for RF
signal captures, as well as extended playback via the mA-6806’s arbitrary waveform
generation.
Principles of Operation
The mA-3A01 interfaces to the AXIe PCIe fabric channel and is compliant to the AXIe-1
specification. The mA-3A01 connects to the AXIe backplane with port interface from a
PEX8734 PCIe switch. The PEX8734 PCIe switch contains four downstream x4 wide
ports. Each port is routed to a U.2 connector, giving each SSD a dedicated x4 wide port
interface.
Each SSD presents to the host controller operating system as an independent storage
device. The host controller operating system software may be configured to combine each
SSD into single striped volume for increased read/write bandwidth
