Mellanox MCX556A-EDAT — 2-port 100GbE Adapter
100GbE QSFP28 connectivity for servers and storage platforms
| ||||
|
Genuine Mellanox 2-port 100GbE adapter with QSFP28 ports. The upgrade that unblocks backups, VM migrations and storage traffic without touching your switching architecture.
Where It Pays Off
Moving from 1GbE to 100GbE changes what a server can do: file serving stops being the bottleneck, VM live-migrations finish in minutes instead of hours, and iSCSI/NVMe-oF storage links keep up with the array behind them.
- VMware / Hyper-V / Proxmox hosts — more bandwidth per VM, fewer bottlenecks
- Storage networks — iSCSI, NFS and NVMe-oF links that keep pace with flash arrays
- Backups — backup windows shrink when the pipe is 100GbE
Genuine Vendor Option
Vendor-branded adapters mean vendor driver support and no third-party compatibility caveats in picky platforms. Pulled from working hosts and bench-tested.
