Data Centers in Silicon Valley
109 Facilities Tracked

54 data center operators maintain facilities in Silicon Valley. The three largest are Equinix (16 facilities), Digital Realty (12), and Vantage (10). The full operator set spans hyperscale providers, multi-tenant colocation campuses, network carriers running points of presence, and enterprise-owned facilities. Operators that run multiple sites under subsidiary or brand names are counted once under the parent company, so the rankings reflect the operator most consistently named for each site across the source datasets in Silicon Valley rather than how any single listing labels it, and the counts update as new facilities are verified across the market.

Data center infrastructure in Silicon Valley is concentrated in the Santa Clara market, which hosts 60 of the region's 109 facilities. The remaining facilities are distributed across 2 adjacent cities, each opening to a dedicated page with operator detail and verified addresses for that local market. The concentration reflects how power availability, fiber routes, and land near existing campuses pull new capacity toward the leading submarket rather than spreading it evenly across Silicon Valley, a pattern that shapes both where new builds land and where retired hardware eventually turns over.

Common questions about data centers in Silicon Valley, answered using verified data from ITAMG's multi-source directory of 109 facilities, each figure drawn from up to 15 source datasets. The questions below cover how many data centers operate in Silicon Valley, which operators run the most facilities, where they concentrate geographically, and the data sources behind the listings.

ITAMG compiles the Silicon Valley data center directory through a multi-source entity resolution process. Raw facility records from up to 15 source datasets are ingested, normalized, and deduplicated using a four-tier matching algorithm (Google Place ID matching, address normalization, coordinate proximity, and operator-name similarity). Where a facility hosts multiple providers, the Index reports the facility operator, which may differ from a provider named in the facility's name. Each merged facility receives a confidence score from 0 to 100 based on source count, address verification quality, operator confirmation, data richness, and source authority. Only facilities scoring 20 or higher and passing a data center classification filter are included in the public directory. The Silicon Valley directory currently includes 109 verified data center facilities operated by 54 providers across 3 member cities. Every Silicon Valley facility in this database is cross-checked where more than one source dataset reports it before it appears in the public listing. Counts describe the facilities included in this directory.
