Always Disable “Over Commit” Before Creating LUNs When Using StorNext with Q-Tier

Why Disable "Over Commit" When Using StorNext and Q-Tier?


When you use StorNext with Quantum’s QXS Q-Tier, always disable the “over commit” feature before you create any LUNs. If “over commit” is enabled, it is possible to overprovision the LUNs and unknowingly run out of disk space. This could result in the loss of files that were written into the LBA range that was not provisioned with physical storage. This article provides some guidelines and recommendations.

Notes on Q-Tier Capacity Allocation and Utilization


Q-Tier determines used capacity based on used pages in the virtual LUN, and it determines which pages are used based on which pages are allocated. Pages are allocated when being written to by StorNext.
