• Maximum supported memory per processor: 1.57 TB, with a practical limit of 786 GB for the current configuration.
• Memory bandwidth reaches 68.3 GB/s, thanks to a quad‑channel DDR4 architecture.
• Effective memory speed is 2133 MHz (rated at 2400 MHz), ensuring low latency and high throughput.
• Integrated Smart Array P440ar controller with 2 GB Flash Back‑Up Cache for data protection.

Storage & RAID Flexibility

The HP 835847‑425 offers versatile storage options:

• Two Hot‑Swap SAS 6 Gb/s, 2.5” drives, each 300 GB, providing a total of 600 GB raw capacity.
• Supports RAID levels 0, 1, 5, 6, 10, 60, and advanced ADM configurations for redundancy or performance optimization.
• The Smart Array P440ar controller delivers PCIe 3.0 x8 throughput, ensuring fast data paths.
• Maximum storage capacity of up to 100 TB (when fully populated with additional drives).

Networking & Remote Management

Connectivity is robust and future‑proof:

• Four Gigabit Ethernet RJ‑45 ports powered by the HP 331i controller, supporting IEEE 802.3 standards.
• Integrated Lights‑Out (ILO) 4 remote management provides out‑of‑band control via IPMI 2.0 and SMASH CLP protocols.
• Redundant power supplies (1+1 configuration) ensure continuous network operation even during maintenance or failure events.

Graphics & Peripheral Support

While primarily a server, the HP 835847‑425 includes basic graphics and peripheral interfaces:

• Matrox G200 graphics controller with VGA output for console access.
• Two USB 3.0 Type‑A ports and four USB 2.0 ports for device connectivity.
• One serial port for legacy management or diagnostic tools.

Form Factor & Physical Characteristics

The server’s design balances density with manageability:

• 5‑U tower chassis (rack units) measuring 21.9 cm in width and 30 kg in weight.
• Hot‑swap drive bays sized at 2.5” for easy maintenance.
• Power supply rated at 500 W, with an energy‑star certified design to reduce operational costs.
