This is what happens in a 3PAR system, whenever a disk is added to the system it is divided into 1GB blocks of space called Chunklets. Over time Chunklet mellowed out, he realised hey it’s good to share and instead of demanding a whole disk to himself he was happy with 1GB of any given disk. So, I have Updated four new HPE SN3600B (Brocade G610) Switches from 3PAR 101 – MEET CHUNKLET! – D8TADUDE 3Par Chunklet. FOS 9 is supported for most 32GB Switches and you can Update from v8.2.1d or v8.2.2a or later.

Phase 2 – Analyzes and rebalances space usage between disks associated with each node (intra-node tuning).
