MF/CTR: The more I hear it the more it sounds like the caching capability is at the foundation of the storage pool tiering infrastructure.
Hu/HDS: That’s right. It is the key because if you have those caches in separate nodes and you can’t use those caches as one global cache, then you’ve got silence. That’s where you split the workload between those silos to be able to utilize them and that’s more operational cost.
MF/CTR: If you have effective caching, then you’ll be able to set up a foundation to both scale up and scale out without having to go crazy in terms of capacity?
