Traditionally, Helix Core servers required block storage attached directly to them, such as internal drives, Fibre Channel SAN, or direct-attached SAS disk trays. This requirement meant that, in a typical “scale-up” way, the entire environment was constrained to a physical maximum based on the technologies deployed.
By tweaking the way that the depot data is served up to a Helix Core server and using NFS over RDMA on PowerScale, we can deliver extreme single-stream throughput speeds to ensure that the Helix server can move data in the best time possible. An additional benefit of the PowerScale scale-out architecture is that the attached depot storage can grow seamlessly up to petabytes in a single namespace, while remaining online and with no impact to clients. This capability eliminates the traditional constraints of having to upgrade your entire array or head, migrate LUNs, re-stripe data, concatenate LUNs, or expand dynamic volumes, by growing the whole file system on the fly.
An added advantage of having Helix Core clients connected to a PowerScale system is the ability to host NFS workspaces, which enables multiple clients to use the same workspace from multiple hosts.
