Dell Technologies recommends the Isilon configuration for storage in clusters using PowerScale for their primary HDFS storage.
Machine function | Component |
Model | Isilon H5600 (hybrid) |
Chassis | 4U |
Nodes per chassis | 4 |
Node storage | Twenty 10 TB 3.5 in. 4 kn SATA HDD |
Node cache | Two 3.2 TB SSD |
Usable capacity per chassis | 500 TB |
Front-end networking | Two 25 GbE (SFP28) |
Infrastructure (back-end) networking | Two InfiniBand QDR or two 40 GbE (QSFP+) |
Operating system | OneFS 9.2 |
The Isilon configuration is sized for typical usage as primary HDFS storage with Cloudera CDP Private Cloud Base clusters and the PowerScale Worker node configuration.
Two Ethernet network ports per node are included for connection to the Cluster Data network or a PowerScale storage network. Two additional network ports are included for connection to the PowerScale back-end network. These additional ports can be either InfiniBand QDR or 40 GbE, depending upon on-site preferences.
One Isilon H5600 chassis supports four Isilon H5600 nodes. This configuration provides approximately 594 TB of usable storage. At 85% utilization, 500 TB of HDFS storage is a good guideline for available storage per chassis.
This configuration assumes that the PowerScale nodes are primarily used for HDFS storage. If the PowerScale nodes are used for other storage applications or clusters, you must account for it in the overall cluster sizing. You can also use other Isilon H5600 drive configurations.
