How To
Summary
To avoid media errors the IBM 7226-1U3 external media enclosures with installed LTO tape drives should not be mounted directly above or bellow POWER System CEC enclosures. Modern LTO8 and newer drives operate within tight mechanical tolerances due to higher track density and tight servo tolerances. Because of these tolerances there is a possibility for low‑level vibrations originating from the CEC to affect the read and write performance of the LTO tape drive when installed directly above or bellow the CEC.
Environment
The IBM 7226‑1U3 media enclosure should be installed with a 1U vertical separation from ALL Power Systems CEC enclosures. Direct, zero‑clearance installation of a 7226‑1U3 enclosure from a Power Systems CEC enclosure can result in degraded read/write performance and tape errors.
