Radisys was ultimately selected due to Radisys' wealth of telecom platform expertise, flexibility and rapid innovation, along with 25+ years of experience providing telecom professional services. They were not looking to purchase just a few racks of equipment, instead they requested 20 racks—all to be delivered in three months' time. Since then there have been 155 racks deployed at 7 different sites, each deployed in just 14 days. Their network is now successfully carrying a revenue generating service. V ERIZON'S SOF T WA RE A RCHITEC TURE A ND REQUIREMENT S Verizon runs a PAAS system in production and their software architecture is container-native architected around a Mesos cluster. The platform addresses multi-tenant development requirements, but all internal Verizon. They built an internal "platform" of services around DC/OS that includes logging services, monitoring, "external" networking and storage (both object and block). Some services are internally developed, some open source, while others are commercial. Major components include EMC ECS object storage, EMC ScaleIO block storage, and various/custom logging and monitoring packages. To learn more about the overall project, watch "How to Stand Up a 600 Node Bare Metal Mesos Cluster in Two Weeks"—a YouTube Video presented by Craig Neth, Distinguished Engineer—Architecture & Infrastructure from Verizon Labs. DCENGINE DELIV ER S THE PL ATFORM REQUIREMENT S Verizon selected the Radisys DCEngine, a hyperscale storage and compute solution, that is employed by Radisys' Professional Services. Verizon selected Radisys not only for our high density solution, but also our integration and development expertise. Radisys collaborated with Verizon to rapidly engineer and deploy the solution. Radisys continues to work in an agile style of development with Verizon introducing new technologies, higher densities and even specialized cooling. Verizon's DCEngine initial rack configuration comprised of CoreOS, 4x Cumulus switches, 10x storage sleds, 10x compute sleds and 2x PSU. The 30 servers/rack consisted of: 50 CPU sockets, 960TB spinning storage (10x16x6TB), 55TB SSD, at least 300 cores, and 3.8TB+ DRAM.
