Riverbed Steelhead Adaptive Data Streamlining Modes
- Default This setting is enabled by default and works for most implementations. The default setting:
- Provides the most data reduction.
- Reduces random disk seeks and improves disk throughput by discarding very small data margin segments that are no longer necessary. This Margin Segment Elimination (MSE) process provides network-based disk defragmentation.
- Writes large page clusters.
- Monitors the disk write I/O response time to provide more throughput.
- SDR-Adaptive Specify to include the default settings and also.
- Balances writes and reads.
- Monitors both read and write disk I/O response and, based on statistical trends, can employ a blend of disk-based and non-disk-based data reduction techniques to enable sustained throughput during periods of high diskintensive workloads. Important: Use caution with this setting, particularly when you are optimizing CIFS or NFS with prepopulation. Please contact Riverbed Technical Support for more information.
- SDR-M Performs data reduction entirely in memory, which prevents the Steelhead appliance from reading and writing to and from the disk. Enabling this option can yield high LAN-side throughput because it eliminates all disk latency. SDR-M is most efficient when used between two identical high-end Steelhead appliance models; for example, 6050 - 6050. When used between two different Steelhead appliance models, the smaller model limits the performance. Important: You cannot use peer data store synchronization with SDR-M.
