Mellanox MCX455A-ECAT — 1-port 40GbE Adapter
40GbE QSFP+ connectivity for servers and storage platforms
| ||||
|
Genuine Mellanox 1-port 40GbE adapter with QSFP+ ports. The upgrade that unblocks backups, VM migrations and storage traffic without touching your switching architecture.
Where It Pays Off
Moving from 1GbE to 40GbE 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 40GbE
Genuine Vendor Option
Vendor-branded adapters mean vendor driver support and no third-party compatibility caveats in picky platforms. Sealed new stock at parallel-import pricing.
