June 23, 2023

HP is a well-known brand in the IT industry, offering a range of products and solutions for various networking needs. Among its offerings are switches, which are devices that connect multiple devices on a network and direct data traffic between them. HP switches come in different models and specifications, depending on the size, performance, and features of the network. In this article, we will compare four HP switches: R8N85A, J9774A, J9776A, and J9772A. These are all part of the HP Aruba 2530 series, which are designed for small to medium-sized businesses and enterprise branch offices. They are managed switches, meaning they can be configured and monitored remotely through a web interface or a command-line interface. They also support various security features, such as access control lists, port security, and 802.1X authentication.

R8N85A

The R8N85A is also known as the HP Aruba 2530 48G PoE+ 2SFP+ Switch. It has 48 Gigabit Ethernet ports that support Power over Ethernet Plus (PoE+), which means they can provide up to 30 watts of power to connected devices such as IP phones, cameras, or wireless access points. It also has two 10 Gigabit Ethernet SFP+ ports for uplink or stacking purposes. The switch has a total switching capacity of 176 Gbps and a forwarding rate of 112 Mpps (million packets per second). The switch supports up to 16K MAC addresses and up to 256 VLANs.

J9774A

The J9774A is also known as the HP Aruba 2530 8G PoE+ Switch. It has eight Gigabit Ethernet ports that support PoE+, with a total PoE power budget of 67 watts. It also has two dual-personality ports that can be used as either Gigabit Ethernet or SFP ports. The switch has a total switching capacity of 20 Gbps and a forwarding rate of 14.8 Mpps. The switch supports up to 8K MAC addresses and up to 64 VLANs.

J9776A

The J9776A is also known as the HP Aruba 2530 24G Switch. It has 24 Gigabit Ethernet ports and four dual-personality ports. It does not support PoE+. The switch has a total switching capacity of 56 Gbps and a forwarding rate of 41.6 Mpps. The switch supports up to 16K MAC addresses and up to 256 VLANs.

J9772A

The J9772A is also known as the HP Aruba 2530 48G PoE+ Switch. It has 48 Gigabit Ethernet ports that support PoE+, with a total PoE power budget of 382 watts. It also has four dual-personality ports. The switch has a total switching capacity of 104 Gbps and a forwarding rate of 77.4 Mpps. The switch supports up to 16K MAC addresses and up to 256 VLANs.

Conclusion

As we can see, the four HP switches have different specifications and features, depending on the network size and requirements. The R8N85A is the most powerful and versatile switch, with the highest number of ports, PoE+ support, and SFP+ ports. The J9774A is the smallest and most compact switch, with only eight ports and PoE+ support. The J9776A is a non-PoE switch with moderate performance and port density. The J9772A is similar to the R8N85A but with lower SFP+ port speed and PoE power budget. The choice of the best switch depends on the network needs and budget of the user.
