The City of San Jose issued three building permits of subtype 'Data Center' for tenant-improvement work at 123 Great Oaks Blvd (APN 706-02-054 in the permit records; owner of record Equinix Hyperscale (2SV12) LLC): 2024-108710-CI 'EQUINIX TI (BEPM 100%) DATA CENTER' (43,317 sq ft, valuation USD 48.4 million) on 8 October 2026, 2026-141003-CI 'SV12x-F2.3 FIT OUT DATA HALL (I & J)' (14,585 sq ft, USD 14.5 million) on 16 October 2026 and 2026-140996-CI 'SV12x-F2.4 FIT OUT (K & L)' (14,585 sq ft, USD 18.0 million) on 19 October 2026. The City's Active Building Permits list (current to 26 October 2026) shows each with building, electrical, plumbing and mechanical plan approvals complete and no final date. The project recorded here is the data-hall fit-out these permits authorise inside the SV12 building of Equinix's Great Oaks South Data Center; it is permitted as of 19 October 2026, when the last of the three was issued. No start or completion of the works, added data-hall capacity or IT load is established, and nothing is asserted about the operating state of SV12, SV18 or SV19. evidence

Equinix SV18 — new IBX colocation data centre, now open (127 Great Oaks Blvd)

Equinix's product-update post of 5 August 2026 on its own community site says 'SV18, a new Equinix IBX facility in Silicon Valley, California is now open', 'expanding Equinix colocation presence' and providing 'additional Equinix colocation capacity'. This records SV18, the Great Oaks South building at 127 Great Oaks Blvd, as an operating Equinix colocation data centre on 5 August 2026, the post's date. It is not an opening date. The City's data-centre fit-out permit 2026-134965-CI for 127 Great Oaks Bl, issued 3 September 2026 and still active on 26 October 2026, shows build-out continuing inside the building, so full fit-out of SV18 is not asserted, and no capacity or IT load is recorded. evidence

Operational last observed as of 2026-08-05 · Authoritative status update

The California Energy Commission notice of determination (Great Oaks South Backup Generating Facility (SV18), SCH 2020100431) says the Great Oaks South Data Center 'consists of three 182,350 square foot, two-story data center buildings (SV12, SV18, and SV19) at 123, 127, and 131 Great Oaks Boulevard in San Jose', records that the Bay Area Air Quality Management District approved on 28 April 2026 an Authority to Construct for six emergency backup diesel generators for Building SV18 (application 738296) after earlier Authorities to Construct for seven engines supporting SV18, and names Equinix LLC as project applicant.

Location details

Coordinates: 37.23377, -121.78298
Geometry licence: public-record-source-terms
Use scope: Campus locator
Scope class: official_tax_parcel_union_centroid
Authority: Official source
Source entity: Campus
Method: official_county_parcel_union_centroid
Derivation: direct_geometry
Precision scope: Centroid of the union of Santa Clara County FY2026 parcels 706-02-057 (situs 123 Great Oaks Bl, the SV12 building) and 706-02-060 (situs 127 Great Oaks Bl; SV18 at 127 and SV19 at 131), one contiguous polygon of 18.00 geodesic acres, about 481 by 345 m. The centroid lies inside parcel 706-02-060, about 20 m from the SV12 parcel. It locates the three-building Great Oaks South campus, not the SV12 building or its data halls.
Horizontal uncertainty: Not reported
The county publishes its parcel polygons 'as is' with no positional accuracy; the point represents an 18-acre, three-building campus, and the positions of the SV12 building and its data halls within it are not published.
Geometry evidence: 327e6717

A locator places the site on the map. It is not a building footprint, a construction extent or a surveyed boundary unless the use scope is an official boundary, and even then it is a parcel or permit boundary.
