 - SD-Fabric is a **natively disaggregated solution using bare metal switches with merchant silicon ASICs**.
   Instead of using OEM networking hardware, SD-Fabric uses hardware directly from ODMs.
   The trend of using bare metal (white box) switches is unmistakable in the networking industry today,
-  spurred by the massive bandwidthdensity and growing sophistication of merchant silicon ASICs.
