Fully Scheduled Lossless Architecture
The Arista 7500 platform is a purpose-built multi-chip system with end-to-end scheduling: a cell-based fabric sprays uniform cells across all fabric links, Virtual Output Queues eliminate head-of-line blocking, distributed credit scheduling keeps every egress port independent, and deep buffers absorb in-cast and bursts without packet loss – so a fully populated chassis behaves like a single, internally lossless switching chip. All models run Arista EOS.
Deployment Scenarios
Spine and core: deep-buffer, fully scheduled forwarding for data center spine and service provider core roles
Turnkey commissioning: chassis, power, fabric and supervisor arrive as one configured bundle – add line cards for your port mix
Incremental scale-out: populate line card slots over time; all modules are hot-insertable field-replaceable units
AC power estates: this bundle is the AC configuration
Choosing Among the Bundle Variants
Bundle suffixes decode as follows: no suffix is AC power with a standard supervisor, -D substitutes the SSD-equipped supervisor, -DC substitutes DC power supplies, and -DC-D combines DC power with the SSD supervisor. Chassis, fabric modules and slot counts are identical across the variants of a given size.
