A Atlantis Computing Case Study
CDW, a Fortune 500 technology solutions provider with more than 8,600 employees, ran virtual desktops for 95% of its internal users on Citrix XenApp. As the environment scaled—including a 20% user increase after an acquisition—their EMC SAN became a bottleneck (storage processors >85% utilized), causing unpredictable performance, frequent user complaints and rising help‑desk volume; a SAN upgrade would have cost over $50,000.
CDW deployed Atlantis USX, a software‑defined storage solution that handles I/O from server RAM, offloading more than 80% of virtual desktop IOPS in testing and eliminating the need for SAN/SSDs for XenApp. The change cut storage requirements by ~85%, delivered >300 IOPS per user with near‑zero latency, reduced login times by 40% and app launches by 50%, cut help‑desk calls by 70% within two months, and produced roughly $50 per‑user storage CAPEX savings—about a 50% reduction in total solution costs.
