The Sales Manual for various Power11 systems no longer lists the EN2A or EN2B adapters. There indeed are 32Gb and 64Gb adapters that replace it, like the EN1J (and EN1K) adapters that are PCIe4 2-port 32Gb Optical Fiber Channel adapters and the EN1N (and EN1P) adapters that are PCIe4 2-port 64Gb Optical Fiber Channel adapters.
The 32Gb adapters will support running 8, 16 or 32 Gbps. The 64Gb adapters will support running 16, 32 or 64 Gbps.
So, depending on your needs, the EN1J/K or EN1N/P adapters may be a good replacement for the older EN2A/B cards.

Subject: Power11 and HBA 16GB
I have a question. Does Power11 no longer support 16GB HBAs? EN2A and B are being withdrawal, Is a new card coming, or will everything be 32GB and 64GB?
