Description:
  • HP J9728A#B8X | Aruba 2920 Series 2920-48G 44 x RJ-45 10/100/1000Base-T and 4 x Dual Personality SFP Ports + 2 x Expansion Module Layer 3 Managed Stackable Gigabit Ethernet Network Switch
  • HP Aruba 2920-48G (J9728A#B8X) is the switch IT teams supporting teams scaling out AI/ML training clusters that need fast east-west links often turn to when they need something that just works. This model fits data center and server-room deployments: virtualization hosts, NAS and SAN backbones, render farms and AI/ML training nodes that move large volumes of data between servers. It also works well as an aggregation switch feeding traffic up from access-layer switches. On the port side, you get 55 total network ports, laid out as 48xGigabit EthernetRJ-45 and 4xGigabit EthernetSFP (mini-GBIC),Uplink and 2xExpansion Module and 1xStacking Module, topping out at Gigabit (1GbE) per port. Because it supports Layer 3 routing, inter-VLAN traffic and routing tables can live on the switch instead of a separate router. It rounds this out with SFP (mini-GBIC),Stacking Module,Expansion Module expansion for uplinks and stacking so multiple units run as one logical switch. With 1 (GB) of onboard flash, firmware and configuration backups don't depend on a remote server. Physically, it's rack-mount, in a 1U footprint, rack-friendly, drawing ac input power and exhausting air standard front-to-back airflow, so it fits cleanly next to existing gear. GotoDirect sources this HP Aruba switch as a genuine, warranty-backed unit, with fast shipping across the US.
