Hello,

To support your storage we need to deep dive in the logs, it could be an issue with cache battery, or simple a learn cycle of the cache battery.

In the log you should have a

controllerId batteryState

can you check it?

Thanks

Hi , 

Thank you for your answer. I have screenshot of the log.I'm share it.

It gives a warning to replace the battery.
However, after replacing the battery and charging it, it works without any problems for a few hours or a few days, and then the slowdown problem occurs again.

Hi,

Unfortunately, the picture did not load. The storage slowdown reoccur after the battery replacement might due to the cache has not been properly cleared, but this need to be determined by the support if this is the root cause. Clearing cache may result to data lost. I may recommend to contact support to provide logs to confirm the issue. Also, there is a need to look into updating the SCOS, as currently the recommended is 7.4.21.

@DELL-Joey C​ This product has become EOS. We cannot get support. How can we proceed?

Did you try to contact support even if the product is EOS? Normally they can give you support anyway after having payed a fee.

Hİ Marco,

We will try to buy post support.Thank you for your enteresting.

Best regards
