The Dell Technologies Validated Design for HPC BeeGFS Storage is available in three base configurations: Small, Medium, and Large. These base configurations can be used as building blocks to create additional flexible configurations to meet different capacity and performance goals as illustrated in Figure 1:
The metadata component of the solution that includes a pair of metadata servers (MDS) and a metadata target storage array remains the same across all the configurations as shown in Figure 1. The storage component of the solution includes a pair of storage servers (SS) and a single storage array for the small configuration, while a medium configuration uses two storage arrays, and a large configuration uses four storage arrays. The PowerVault ME5024 storage array is used as the metadata storage, and PowerVault ME5084 arrays are used as the data storage.
To scale beyond a large configuration, an additional pair of storage servers are needed. The additional storage server pair can have either one, two, or four storage arrays as indicated in the scalable configurations.
