Figure 2 shows the large configuration architecture with four PowerVault ME5084 storage arrays:
In figure 2, the management server (the topmost server) is a PowerEdge R650. The MDS function is provided by two PowerEdge R750 servers. The MDS pair is attached to a PowerVault ME5024 through 12 Gb/s SAS links. The PowerVault ME5024 hosts the metadata targets.
The SSs are a pair of PowerEdge R750 servers. The SS pair is attached to four fully populated PowerVault ME5084 storage arrays through 12 Gb/s SAS links. The four PowerVault ME5084 arrays host the storage targets.
The solution uses InfiniBand HDR100 as the data network connecting the metadata targets to the compute clients, and InfiniBand HDR to connect the storage targets. Gigabit Ethernet is used for management operations.
