Case Study: Swisscom achieves 60% data-centre space savings and 80% lower latency with Dell Technologies PowerMax

Swisscom upgrades storage with high-density appliances reducing latency by 80 percent while freeing up 60 percent of the data centre with Dell EMC PowerMax

Swisscom, a leading Swiss telecommunications provider, faced critically limited space in its two data centres and needed a smaller-footprint, highly available storage platform to maintain always-on services for customers (including banking workloads). To replace aging VMAX arrays without expanding facilities, Swisscom selected Dell Technologies’ Dell EMC PowerMax (PowerMax 8000) under a storage‑on‑demand arrangement.

Dell Technologies deployed PowerMax with Dell EMC ProSupport Plus and Residency/Services, delivering a high-density solution that cut data‑centre space by 60% (storage racks reduced from 20 to 4), lowered power costs by 30%, and improved performance (one server’s latency fell from 10 ms to 2 ms) while increasing throughput. The changeover was seamless with no customer interruptions, enabled fast restores via snapshot/clone functionality, and provided flexible, on-demand capacity and rapid time‑to‑value through Dell Technologies’ services and support.
