HPE P42041-B21 — 2-port 10/25GbE Adapter
10/25GbE SFP28 connectivity for servers and storage platforms
| ||||
|
Genuine HPE 2-port 10/25GbE adapter with SFP28 ports. The upgrade that unblocks backups, VM migrations and storage traffic without touching your switching architecture.
Where It Pays Off
Moving from 1GbE to 10/25GbE 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 10/25GbE
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.
