Storage planning and configuration

The storage configuration must be carefully planned based on the overall workload characteristics that are intended for IBM Storage Scale.

The factors to be considered in planning the storage configuration include:
  • Expected response time, during peak and off peak hours.
  • Workload profiling to understand the data access requirements, both in terms of throughput (MiB per second) and I/O operations per second (IOPS).
  • Plan for adequate storage resources not just for “normal” network file serving but also for advanced functions.
The storage configuration includes the following details:
  • Number of storage nodes.
  • Storage disk subsystems.
  • Number and type of disk drives.
  • Total capacity
  • Projected IO throughput and IOPS

A file system that resides on fewer disks, or disks that are mapped on to RAID arrays that comprise slower lower speed disk drives, can result in a lower number of active concurrent SMB connections per protocol node.
