Introducing ExaSAN PCIe 3.0 Storage System1.1 Overview1.1.1 What is the ExaSAN SolutionDeveloped by Accusys Storage Ltd., a worldwide leader in RAID (Redundant Array ofIndependent Disks) storage systems, ExaSAN (pronounced “X-sa-SAN”) is a family of storageand switch products that take advantage of well known PCIe (PCI Express) technology speeds,standards, and roadmap.The current ExaSAN products employ PCIe3.0 protocol that provides 8 Gb/s per lane transfers.With 4 lane QSFP (Quad SFP) connector and cable, ExaSAN can transfer up to 32 Gb/s byusing single connection.Post production work including non-linear editing (NLE) requires high bandwidth storage toquickly move the volume of data being processed and ExaSAN storage solution meets thosedemands. The high bandwidth provided by ExaSAN technology allows the client to completeediting tasks in a much shorter time to save time and money.ExaSAN solution, including its complete line of rack mount RAID systems, tower RAID systems,PCIe switch systems and accessories, support to build DAS (directly attached storage) andSAN (storage attached network) environments. Figures below depict the ExaSAN B08S3-PSsystem solution architecture in DAS and SAN environment.DAS environmentDAS with C1M environment
