Stop. Don't use FC-AL Quick emulation

If you have platforms with Fibre Channel connections that do not support fabric configurations, maybe you have a classic FC-AL. A year ago, I had the idea to change my old FC hubs with some new FC switches. These boxes support fabric and one FC-AL Quick emulation. The white paper was excellent, but when we put it in production, the databases went down in performance. Over the past two months, my local hardware vendor told me about a bug register at my installation and another in Germany. A few days later, they installed the new microcode, but THE PROBLEM CONTINUES. My only solutions were: 1. go back to hub; and 2. go back to fabric.
