What is the maximum number of 10GbE ports supported in a single BlackDiamond X8 chassis?

A single BlackDiamond X8 chassis supports up to 768 wire-speed 10GbE SFP+ ports or 384 10GbE RJ45 ports. With three chassis per rack, you can achieve 2,304 10GbE ports per rack. The 8 I/O slots accommodate interface modules configured for your specific connectivity requirements.

What is the port-to-port latency, and why does it matter?

The BlackDiamond X8 delivers 2.3 microsecond port-to-port latency for 64-byte packets. This sub-microsecond performance is critical for high-performance computing, financial trading systems, and real-time applications where deterministic, predictable latency directly impacts application performance and user experience.

Does the chassis include power supplies and cooling?

The BDX8-AC chassis includes 5 fan trays for thermal management but does not include power supplies or blank panels. Power supplies must be purchased separately and support both high-range (200-240VAC) and low-range (90-132VAC) input voltages. Up to 8 power supplies can be installed for redundancy.

What management and redundancy options are available?

The BlackDiamond X8 requires a minimum of 1 management module (BDX-MM1) and supports 2 modules for 1+1 redundancy. ExtremeXOS 15.1 or later provides centralized management. The modular architecture supports N+1 redundancy for power supplies, with 4 required for full 20 Tbps redundancy.

Can I mix different port speeds (10GbE, 40GbE, 100GbE) in one chassis?

Yes. The 8 I/O slots support different interface module types, allowing mixed configurations. You can deploy 48-port 10GbE modules, 12-port 40GbE modules, and future 100GbE modules in the same chassis. This flexibility enables gradual technology transitions and heterogeneous workload support.

What is the power consumption per 10GbE port, and what are total system power requirements?

The BlackDiamond X8 consumes 5.6 Watts per 10GbE port, delivering industry-leading efficiency. With full 20 Tbps configuration, total system power reaches approximately 8,460 Watts at power supply output and 9,475 Watts at input (200-240VAC), generating 32,338 BTU/hour heat load.

What routing and VLAN capabilities does the BlackDiamond X8 support?

The chassis supports up to 1 million L2/L3 forwarding entries (expandable to 512K with XL modules), 4,094 VLANs (Port, Protocol, IEEE 802.1Q), 384 link aggregation groups with up to 64 members per trunk, and 9,216-byte jumbo frame support for optimized throughput and multi-tenant isolation.
