Hi all,

1. How does the process of space reclaim work on a VMAX thin device? How different is the reclaim from free w.r.t a sequential vs random I/O profile? Also, is there any significance of the sector CRC\Partial CRC\Old CRC on a Symmetrix TDEV space reclaim? 

2. What is the impact of space reclaim\free commands on the VMAX Cache?

Thanks,
