Isilon Tiering

The Isilon Tiering solution from Dell EMC is called CloudPools.
Dell EMC Isilon CloudPools software provides policy-based automated tiering that allows for an additional storage tier for the Isilon cluster at your data center. CloudPools supports tiering data from Isilon to public, private or hybrid cloud options. This technology is a form of storage pools, which are collections of storage volumes exported to a shared storage environment.
Cloud tiering and data tiering (or archiving) can deliver significant cost savings as part of a cloud data strategy by offloading unused cold data to more cost-efficient cloud storage solutions. The approach you take to Isilon tiering can either create an easy path to the cloud with native access and full use of data in the cloud or it can create costly cloud egress and lock-in. Array block-level tiering is a mismatch for the cloud. Isilon cloud tiers blocks rather than entire files, which the following ramifications:
  • Limited policies result in more data access from the cloud.
  • Defragmentation of blocks leads to higher cloud costs.
  • Sequential reads lead to higher cloud costs and lower performance.
  • Tiering blocks impacts performance of the storage array.

When it comes to considering Isilon data tiering and Isilon cloud tiering, it’s important to understand your cloud tiering choices. Cloud tiering and archiving can save you millions by offloading infrequently accessed cold data to cost-efficient cloud data storage. But, the approach you take can either create an easy path to the cloud for file data with full use of data in the cloud or it can create costly cloud egress and lock-in.
