Construction: Equinix SV4 is a Tier‑III, single‑tenant data center at 255 Caspian Drive, Sunnyvale, CA, consisting of a 1‑story reinforced concrete building with 119,756 sq ft of gross floor area on a 6.49‑acre site, providing 67,619 sq ft of colocation space, powered by 8 MW of capacity, owned by Brookfield and operated by Equinix, and fully operational as of 2026.
Land transaction: Brookfield acquired the property in 2026 for approximately $90 million.
Facility class: Colocation · Telecom Edge · Enterprise · Mixed
Workloads: interconnection / peering · enterprise colocation · high-density compute (supports high-density cabinets / next‑gen cooling) · telecom/edge networking
Availability tier: Tier III equivalent / Tier-III (per Brookfield property listing and facility specification material).
Cooling systems: Free cooling · Advanced cooling · Evaporative cooling · Heat recovery · N+1 cooling redundancy · Hot/Cold aisle containment
Cooling medium: evaporative cooling (recycled water)
Water source: recycled water
Fiber and connectivity: Carrier-rich Equinix IBX with multiple on-ramps and carrier/peering presence; PeeringDB lists SV4 with ~16 networks and multiple carriers present (e.g., AT&T, Zayo, Cogent, Zayo, Wave/Layer42) and Equinix Fabric/Internet Exchange services available. The facility therefore functions as a significant connectivity/peering node in Silicon Valley with direct carrier interconnection options rather than being an isolated single-carrier site.
Operating context: Equinix-operated IBX colocation facility (SV4) at 255 Caspian Drive, Sunnyvale. The building is a single-story reinforced concrete / tilt-up structure converted to a data center; it is operated by Equinix and (per property records) owned/leased in a net-lease arrangement by Brookfield Properties. Cooling uses close‑coupled evaporative (water‑cooled) air handling units and recycled water; generator autonomy and N+1 redundancies are documented. Public materials describe SV4 as serving high‑tech companies and peering hubs; Brookfield property material lists the powered shell as supporting ~6.5 MW of critical IT capacity (owner property spec).
